Photoshop path tool

There are a lot of hotoshop tutorials on the Internet, but there is little talk about the path, it is very puzzled, you need to know the path is also a powerful tool in Photoshop. The series of articles you have read will give a detailed explanation of this important concept of Photoshop-path. The content includes the settings and usage of various path tools, the use of menus in the floating path panel, and the use of right-click menus. It also uses examples to describe the path in addition to the image background and outline the image edge, the shift path, the conversion between the selected region and the resource sharing between different programs, tries to fully understand the importance of the path, it helps you master the important weapon to make this drawing.

Paths is an important tool in Photoshop. It is mainly used to select a smooth image area and assist in drawing, draw smooth lines, and define the trajectory of a paint brush, the output input path and the conversion between the selected region. He highlighted the powerful editable feature on the secondary image, and has a unique smooth curvature attribute, which is more accurate and smoother than the channel.

Let's take a look at an example:

　　　　　　

Here we need to extract the tracing below the graph and compare the following schemes:

1. Using a magnetic cable plug-in tool, we can roughly obtain the yingyang with an uneven edge. After Gaussian blur, we can deal with general needs. For example, background, and image matching.

2. In the previous step, the selected region of the magnetic cable can be saved as a channel, and then the channel can be manually adjusted with a paint brush to make it smooth, which may require patience at the pixel level. After a long time of fatigue, yingyang can cope with high-level needs. For example, webpage applications or print backgrounds.

3. You can use the circular selection tool to quickly select and convert it to a path. With the help of the CTRL and ALT keys, you can adjust the path to quickly obtain the yingyang constituency with smooth edges.

4. Of course, if you are confident about the free cable, you may wish to manually draw a constituency.

5. The magic wand tool, based on the color selection, is not big or complete for the color difference in the figure, there is nothing to do here, not to consider.

Believe in this list comparison method, you can intuitively feel the practicality of the path tool. Let me finish playing this movie first.

Step 1: Use a circular tool to quickly circle and select the desired yingyang: (for more intuitive purposes, I reduced the transparency of the fan chart when creating the fan chart, so that the selection area can be clearer .)

　　　　　　　　

In step 2, right-click the dotted line of the selection area and select make work path from the shortcut menu. Then, the selection area is converted to a work path.

　　　　　 　
Careful readers will surely find that the converted path is slightly different from the selected area. The reasons are explained later.

The three black boxes in the circular path in the figure are called the path nodes for adjusting the left and right sides of the curve. The straight line extending from the node is called the normal line of the curve, that is, the tangent of the curve, the black square of the regular line segment is a small prism used to adjust the curvature. drag one of them to change the Curve Curvature of the other side, and the curve between the two normal lines, you can drag two wire handles to change the curvature to the edge suitable for yingyang.

Step 3: Select nodes and press Ctrl to switch to the node selection tool. After the adjustment handle appears, adjust the path to the appropriate one. Note that if you do not have the Conversion Tool on the tool panel, hold down the ctrl key to adjust it.

　　　　　　　

Step 4: Right-click the adjusted path and select make selection to convert the selected area into a selected area. Then, you can proceed as you like.

　　　　　　　

If you are not interested in the path, let's look at it again,

　　　　　　　

In this way, smooth and beautiful lines are drawn using paths. More than that, you can draw more dazzling lines in vector graphics tools and input them to Photoshop through paths, such as illturstrator, CorelDraw, and 3dsmax.

An old saying goes: interest is the best teacher. Therefore, the objective of this movie is to make you interested in the path. Two small examples are provided, but you have to systematically learn how to master it. The following has to begin with the most boring principle.

In Photoshop, paths is a closed or open curve segment made up of the besell curve. Besell is a parameter curve constructed by peb of French Renault Automobile Company in 1962 based on "infinite similarity". Based on this curve, the Design System unisurf of a curve and surface was completed and applied to the company in 1972. The besell method combines infinite function approximation with set representation, making it as handy as using conventional plotting tools to draw curves on a computer. Of course, you may not feel this way, because you don't need a path and think it is difficult to control. Well, after reading this article, I believe your opinion will change. Shows the effect of a standard besell curve. We can see that a besale curve is defined by four points. P0 and P3 define the starting and ending points of the curve, also known as nodes, p1 and P2 are the control points used to adjust the curvature. A polygon composed of four vertices p0p1p2p3 is called the control polygon of the besell curve. By adjusting P0 and P3 nodes, you can adjust the start and end points of the besell curve. by adjusting the position of p1p3, You can flexibly control the curvature of the whole besell curve to meet your actual needs. At the beginning, it may take some time to practice the image. Here is a small experience: in general, first adjust the curvature, And the need is almost the same, then adjust the node, to change the curve position suitable for the need. This sequence can reduce repeated operations. Generally, only one besell curve is not enough to express a complex curve area. In Photoshop, to construct a complex curve, the besell curve group method is often used, the beginning and end of a section of the besell curve are connected to each other. For example. There are usually the following splicing methods using the besell curve, as shown below. A. Connection Mode 　　The whole curve is composed of a direct curve (a direct line connecting the start point and the end point). This curve is generally used to outline a polygon area composed of a straight line segment. A. B. Splicing Mode 　　It is composed of two quadratic or cubic B curves. They reach the continuity of a at the join point, which is called zero-order geometric continuity. B. C. Splicing Mode 　　A whole curve group composed of a one-time betel curve and a second or three-time betel curve. The two besell curves reach the continuity of B at the intersection, that is, the first-order geometric continuity. C. D. Splicing Mode 　　It is composed of two quadratic or cubic B curves. Apart from the continuous CHARACTERISTICS OF C when connecting points, their main normal is connected to the same line, the curvature at the intersection of the two betel curves is the same, that is, the second-order geometric continuity is achieved. D. From a mathematical point of view, although boring, it is helpful for readers to better understand the path. In the next article, let's see where the path tool in Photoshop is. Photoshop provides a group of tools for generating, editing, and setting "paths". They are located in the floating Panel of the toolbox in phtoshop software. By default, its icon is displayed as "pen icon", as shown in the right figure. By clicking the icon with the left mouse button for two seconds, a hidden Tool Group will pop up, with a total of seven tool groups, in the order from left to right, they are "Pen tool", "magnetic pen tool", "free pen tool", "add node tool", "" delete node tool "," node position adjustment tool and node smooth adjustment tool ". Based on functions, they can be divided into three categories: I. node definition tools 　　These include "Pen tool", "magnetic pen tool", and "free pen tool ". They are mainly used for node definition and preliminary planning of the besell curve group. Ii. Node Deletion tools 　　This includes "add node tool" and "delete node tool ". They are used to add or delete the besell curve nodes as needed. Iii. Node Adjustment tools 　　Including the "node position adjustment tool" and "Node smooth adjustment tool ". This tool is used to adjust the position of a curve node and the curvature of a B curve. The specific arrangement of these tools is shown in. The following is a detailed description. This article focuses on node definition tools. I. node definition tool Group 　　Node definition tools include "pen Tools", "magnetic pen Tools", and "free pen Tools". They are used to define nodes and draw paths. 1,Pen tool: This is the most common tool for defining path nodes. Generally, you can use this tool to define nodes manually. The "Pen tool" is easy to use, use mouse to click the left button on the tool icon, select the tool, and click the mouse button in the image to define the node as needed, each time you click the left mouse button, a node of the betel curve is generated. Based on the mouse clicking order, each node is connected by a betel curve (even if it is connected by a straight line segment ). Shows the process of defining three nodes in order (note: the path is not exactly the same as the selected region. You can define a closed path or an unclosed path. At the same time, the path can also have the intersection feature. When the user's mouse cursor is at the starting node, a small "O" is displayed at the bottom right of the mouse cursor "pen", indicating that the path can be closed. If point dragging occurs, the curvature of the curve is also adjusted. For example. Double-click the pen icon. In the options control panel of Photoshop, the pen Options page is displayed ), There is only one option available in the control panel, namely, the rubber band item. If this option is selected, the secondary "rubber band" will be displayed during the next node definition process to help you locate the node. Also known as "rubber band options ". The keyboard control key works with the pen tool to facilitate your operations. In Photoshop, press and hold the [shift] key on the keyboard, keep the connections between the created key points and the last node at an integer multiple of 45 degrees. When you press and hold the [alt] key on the keyboard, the original "Pen tool" will be converted to "Node smoothness adjustment tool" Temporarily. When you press and hold the [CTRL] key, the original "Pen tool" will be converted into "Node location adjustment tool" temporarily ". With the combination of these keys, it is very easy for the user to adjust the besell curve, without having to switch tools, which can greatly improve work efficiency. Another special feature is that when you move the mouse cursor to a defined node (not the starting point ), in this case, the pen tool is immediately changed to the delete node tool. Now, the user can delete the current node. If the mouse cursor moves to the straight line segment connecting the two nodes, the "Pen tool" is changed to "add node tool". The whole process of adding and deleting nodes becomes very simple, and the second-level tool does not need to be replaced constantly through the tool panel. 　 2. magnetic pen tool 　　Definition: it is a newly added Path Generation Tool in Photoshop. It is similar to defining the magnetic loose of a constituency. It uses a fixed range of regions as a reference to automatically analyze the pixel trend of the image, automatically analyzes the boundary area of the object inside the image. The difference is that the magnetic pen tool here generates a path, not a selection area. 　　Feature: the advantage of the magnetic pen tool is not only to easily outline the object contour in the image, but also to "The modifyable path and the smoothness of the path, because the path can be converted to the selected region, and the path is adjustable, the effect of the path in the image background removal application is significantly better than that of the magnetic cable plug-in tool, in addition to the image background, because the selection of the outer boundary area of the object in the image is generated using the magnetic cable tool, in addition to saving the selection as a channel and modifying it, you cannot directly adjust the region selection accurately. However, when using a magnetic pen tool to generate a path to the external boundary of the object in the image, because the obtained path can be directly modified, you can directly modify the path after generating the contour path of the image object to make it better, this is shown in the example at the beginning of this article. At the same time, due to the use of the besell curve group in Photoshop to define the path, the path can have a very smooth appearance, and the adjustment is random, this is difficult to achieve through the adjustment channel, although the channel's functions in constituency editing are not powerful, it is still inherently inadequate in terms of smoothness and subtle adjustment. Because the besale curve group used by the path is a vector representation method, the path accuracy is not the same as that of a channel that represents the selected region, as the image scales, its precision and appearance are affected. Due to the above advantages of the path, after defining the outer contour of an object in the image using the magnetic cable plug-in tool, you can adjust it again, finally, the process of converting a path to a selected region is widely used in precisely removing the image background. 　　Use method: the use of the magnetic plug-in tool is similar to that of the magnetic plug-in tool. 　　You only need to select this tool, and then use the extra break outer boundary that mouse needs in the image to move. During the mouse movement process, the path node is automatically generated, if a user finds that a node is needed, and when the mouse moves so far, photosho [P does not generate a node, the user can click the left button of moue to forcibly define a node, in the process of moving along a certain area, if the moouse movement control is poor, it may lead to deviation from the outer boundary of the object and cause some wrong nodes, (You can delete multiple nodes after pressing the delete key continuously.) After defining the path of a region, you can customize the path based on the actual image structure and processing needs, consider whether to close the entire path. Similarly, move the mouse to the first node and click the left mouse button to close the entire path. An art photo is displayed. The path obtained after the flower body in the image is outlined using the magnetic pen tool and the generated path is added/deleted, the final path obtained by adjusting the node location, adjusting the curvature, and other post-processing operations is the most refined path map than its smooth curve features. (Note the perfect combination of the path and the border of the original image ). 　　Parameters: similar to other path tools, you can use the mouse button to double-click the magnetic pen tool. You can set the corresponding tool attributes in the option control panel, the property settings window corresponding to the magnetic pen tool is named "magnetic pen opitons control panel. As shown in. 　　From the control panel on the left, we can see that the attribute settings of the magnetic pen tool are similar to those of the magnetic plug-in tool. Where: (1) magnetic pen width: Similar to the width of the cable set in the magnetic cable set tool, used to define the diameter of the target area (positive circle type) for reference. (The caps lock can be switched Based on the capital Lock key) (2) frequency valueThe {frequency} frequency value determines the node density generated when the magnetic pen tool is used to drag along the boundary of the object. (3) border color difference[Edge contrast] The boundary color sum determines the magnetic attraction when the boundary color difference is reached. The smaller the value, the easier it is to attract the image in areas with low chromatic aberration, And the finer boundary contour can be extracted. (You can also use the left mouse button to forcibly generate a node) (4) TypeType setting has only one option, pressure, which is only valid for users who use an electronic tablet. When this option works, it indicates that the width of the magnetic cable can be instantly changed by the user stroke pressure transmitted by the electronic tablet. The user's pen pressure intensity directly affects the actual value of the pen width. If the pen pressure value is large, the pen width decreases, and the pen width in the reference area decreases accordingly. (5) curve adaptationCurve Fit: The curve adaptation setting item is unique to the magnetic pen tool. This option determines the maximum error allowed when the path is outlined along the outer boundary of the object, the unit of this option is pixel. The smaller the value, the closer the generated path is to the actual outer contour of the object. However, for some low-resolution North images, due to insufficient image boundary data, that is to say, the intensity is not strong enough, which will lead to a significant step effect on the actual outer contour, and the path will appear very uneven. For such images, we will often encounter, in order to obtain a Smooth outer boundary path as much as possible, you must use this setting to allow the error range. In this way, the final outer contour path is not fully adapted to the outer boundary of the original image, however, the path profile is very smooth. Obviously, there is a problem of syndrome differentiation, which depends on your thoughts. Using this configuration item properly, you can get a smooth path selection to a certain extent. You can use this property to smoothly process some low-precision clipart images, the main contour of the image after automatic smoothing is obtained. 　　Shortcut Key: the keyboard control key works with the magnetic pen tool. Press and hold the [alt] key to switch to the pen tool, press and hold the [CTRL] key, and switch to the node position adjustment tool, if the mouse is located at the curvature adjustment point of a node, it is switched to the "Node smoothness adjustment tool" 3. Free pen tool 　　Definition: it is a tool used in Photoshop to plot the path at will. 　　Usage: It is basically the same as the plug-in tool in the phiotoshop selection tool. Basically, you only need to create an initial point on the image and then drag the mouse to draw the path by hand, 　　Parameter: The Configuration window of this tool is the freeform pen optiones control panel, 　　In this control panel, there is only one setting item, the curve fit option, used to set the allowable error range. 　　Quick key mode: the keyboard control key works with the free pen tool. Press the [alt] key on the keyboard, and the free pen tool will become a tool for adjusting the smoothness of nodes, press the [CTRL] key on the keyboard, and the free pen tool will become a node position adjustment tool. Ii. add or delete a tool group for a node 　　Node addition and deletion tool groups includeAdd node Tool,Delete node Tool. They are used to add or delete the besale curve nodes based on actual needs. At any time, they are elected to use any tool used to create paths. When the mouse cursor moves to the besale curve track, the cursor automatically becomes the Add node tool, when the mouse cursor moves to the location of the besale curve node, the cursor automatically becomes the delete node tool. The Add/delete node tool does not have the corresponding options to be set, therefore, their property control panel is completely empty. 　　In this case, the "no options for the xxx tool" prompt is displayed on the Property Control Panel. Iii. Node Adjustment tools 1. node position adjustment tool 　　Definition: The node location adjustment tool is used to move the path. You can use the node location adjustment tool to move the entire path or only the positions of one or several nodes in the period, you can also move the position of a node's control point. This tool also selects one or more paths. 　　Two notes: 1. Click a node using this tool. The Node shape is changed from a box to a solid square. The Node shape is selected. 2. You often need to change a certain curve and click it directly. A handle will appear on the two nodes of the Curve. Dragging the two handles will only affect the curve, it does not affect the curves at both ends of the node. This is important because operations that only want to change a certain curve are more common. 　　Usage: the node position adjustment tool is very easy to use. Select this tool, move the mouse cursor to a certain path to be moved, and then drag the mouse to adjust the position. This tool can use the ctrl key to call out at any time and anywhere, which is very convenient. The node location adjustment tool can also directly change the location of the besale Curve Control Point. When you use the mouse cursor to click the left mouse button at a node, the control point of this node will be displayed immediately, in this case, you can drag the position of the control point as needed to change the curvature of the besell curve. To change the positions of multiple nodes at the same time, you can press and hold the [shift] key on the keyboard at the same time, click different nodes respectively, so that multiple nodes are selected at the same time. Then, when the mouse point is dragged, all nodes will be moved synchronously, directly affects the location of the whole besale curve group. If multiple nodes have continuous characteristics, only the curvature of the besale curve at both ends will change during synchronization, you can use the node location adjustment tool to select multiple paths at the same time. Generally, if you click the left mouse button at any location of a path, you can select the entire path. To select multiple paths at the same time, you can use the Shift key and then click another path. Another simple method is to directly use the node position adjustment tool to drag points in the image, to define a rectangle area (the operation is similar to using the rectangle selection tool to generate a rectangle area selection in the image. The entire path of all nodes in this rectangle area will be selected. Note that the dragged rectangle area does not need to completely contain all the paths to be selected, as long as any node is inside the rectangle area, the entire path is selected immediately. When you use the node position adjustment tool to adjust the position of a node or control point, if you use the Shift key on the keyboard, you can force the operation to be performed as an integer multiple of the 45 degrees angle. The node location adjustment tool works with the shift key on the keyboard to select and adjust multiple nodes at the same time. 　　Tip: If you want to move the entire or multiple paths, select the desired path and use the free transform path command in the editing menu or press Ctrl + T, you can drag the path to its location. 2. node smoothness adjustment tool Definition: It is used to adjust the position of the control point of a certain betel curve, that is, to adjust the curvature of the betel curve. Under normal circumstances, we use the pen tool to define the nodes of the besell curve group (no drag behavior). After the definition is complete, we will get a group of multiple straight line segments (one besell curve) in this case, the control point of the besell curve overlaps with the node. To adjust the position of the control point of the besell curve, that is, to adjust the curvature of the besell curve, you can use the node smoothness adjustment tool. How to use: the tool for adjusting node smoothness is simple. You only need to select this tool and drag the mouse button at a node in the image path to adjust the node curvature, that is, adjust the position of the control point. If the adjusted node is not the starting or ending point of the path, the mouse is dragged at the node position for the first time, the control points that lead to the two betel curves in total near this node remain in the same straight line. That is, the smooth adjustment tool is used at the node, and the progressive curve adjustment ensures that the curvature of the two betel curves at the node is consistent. Of course, you can also directly adjust the position of each control point so that the two betel curves have different curvature at the intersection point. As an element in plane image processing, paths are very important. As with channel layers, Photoshop also provides a dedicated control panel:Path Control Panel. 　　 As shown in. Similar to other control panels. The Path Control Panel consists of the system button area, Path Control Panel label area, path list area, path tool icon area, and path control menu area, the detailed structure is shown in the path control panel structure. The original image we use and the four path effects in it are shown in. The following describes the main areas that constitute the path control panel. 1. system button area: it is located at the top of the path control panel, and two system buttons are on the right. They are used to minimize/Close the path control panel respectively. If you need to drag the position of the layer control panel, you only need to use mouse to drag it on its blue system bar. 2. Channel label area: the channel label area is located below the system button area. Its main function is to display the type of the current control window or to separate the combined control panel group. 3. Path list area: This area displays the list and name of each path layer. 4. path tool icon area: Used to quickly complete corresponding path operations, located at the bottom of the Panel. 5. Path Control Menu: Used to complete all path control functions. It is a hidden menu and is displayed in the triangle button in the upper right corner. Under normal circumstances, if you use the path tool on the tool panel to outline a path, the path control panel will automatically generate a working path named, if you need to fix the path layer, You can first switch to the new icon in the tool icon group under the path control panel, in this way, the current work Path layer will be automatically named as Path 1. The naming rules for the automatic path layer will be accumulated in sequence for path1), and the surface will be fixed, as shown in. In this article, we will focus on the icon functions of the path tool icon area and the functions of various menu items in the path control menu. I. path tool icon Area There are six tool icons in the path tool icon area. They are fill paths, outline paths, convert paths to choices, select paths, create path layers, and delete path layers. 　　1. Fill path: The fill path tool is used to completely fill the current path with a foreground color. If you select only a part of a path or an unclosed path, Photoshop fills in the Closed Area after connecting the first and end of the path to a straight line segment.   If you need to set the fill path, you can click the fill path tool icon while holding down the Alt key on the keyboard. A setting window is displayed before filling, it is used to set the corresponding properties for filling. Shows the dialog window. The contents area is used to determine the fill color or fill type used. By default, the foreground color is used. In each option, foreground color indicates that the foreground color is used for filling, background color indicates that the background color is used for filling, pattern indicates that the custom image security is used, and black indicates that the color is black, 50% indicates filling with medium gray, and white indicates filling with white. In the blending area, Opacity is used to set the opacity of the fill color, mode is used to set the merging mode, and preserve transparency is used in a non-Background layer to protect the transparent area in the layer. There are two options in the last render area, mainly to prevent the added area from appearing at the edges. The feather raduus determines the feather range, in pixels, The ANTI-ALIASED determines whether to use Smooth settings. 2. "outline path" toolThe role is to use the foreground color along the outer contour of the path to outline the border, mainly to leave the appearance of the path in the image. Shows the specific effect. Strictly speaking, the path profiling tool is actually the result of moving the path along a certain step by using a Photoshop drawing tool. If you click the outline path icon while holding down the Alt key on the keyboard, a stroke path dialog window is displayed. In this dialog box, we can select the tool used to outline the path. Different drawing tools will lead to different outlines. The effect is also influenced by the original pen type of the quilt selection tool. Obviously, using a pencil tool is totally different from using a paint brush tool. In addition, even if you use the same tool, different pen settings will lead to different outlines. In addition to the outline, the subdge blur and other tools provided can also be used to perform operations such as smearing and blurring along the path. With regard to the use of these drawing tools, we provide a few below to outline the paths effect under different drawing tools and different pen type settings. -- -- TIPS: When we outline the path, the most common operation is the outline of a single line in one pixel, but there will be problems at this time, that is, the existence of the moment tooth, which has a great impact on practical value, in this case, we may first convert the path to the selected area, and then perform stroke processing on the selected area. We can also obtain the line of the original path, but can eliminate the moment teeth. 3. Select a pathTo convert the selected path to the selected region that is used to define the processing range when processing the image, you can use the path Conversion Tool to complete the conversion process. For example.   We have outlined the peripheral path of the butterfly. to convert the path to a selected region, you only need to select the path1 layer and then click the tool icon to convert the path to the selected region, to complete the conversion. Similarly, if you press and hold the Alt key on the keyboard, and then click some paths to convert them to the selected tool icon, the setting window is displayed. The setting window name here is the make selection setting window, as shown in. In the make selection dialog box, there are two sets. The Feather radius item is used to set the feather range, in pixels, the ANTI-ALIASED option determines whether the anti-aliasing feature is used during the conversion, the operation groups are located in the second part, and are valid only when the selected region already exists in the current image, this setting determines how to combine the selected region and the original selected region after the conversion. There are four sub-options in total: 1. MEW selection directly replaces the original selection area 2. Merge add to selection with the original region 3. Subtract fron selection subtract the selected area after the current conversion from the original selection area, which is called boolean subtraction. 4. intersect with selection calculates the intersection of the two selected regions, that is, retaining their common parts, that is, Boolean addition. 　　Note:For an open path, the system automatically connects the start and end points with a straight line segment. At the same time, a besell curve, that is, a straight line segment composed of two vertices, cannot be converted separately. For the same reason, A one-time betel curve group (or a straight line) composed of multiple nodes cannot be converted. 4. convert a selection to a path:In Photoshop, not only can the path be converted to the selected operation, but also the selected area can be converted to the path, this operation uses the select convert to path button in the path control panel. This function is used to convert the selected area to a path. Generally, Photoshop veterans usually use this function to convert some images, such as the scanned image into a vector description file, in this way, you can directly import the appearance of the tool, such as 3DS MAX softimage or other three D or vector graphics tools, for lofting and editing operations, for the tool that chooses to convert to a path, we will repeat the first example below, which is already in use and will be easier to understand now. Step 1: Use a circular tool to quickly circle and select the desired yingyang: In this way, we get a selection area. To change the selected area to a path, you only need to click the tool icon to select the path to complete the conversion. Or right-click the dotted line in the selection area and select make work path from the shortcut menu to convert the selection to a work path. As shown in: Careful readers will surely find that the converted path is slightly different from the selected area. If we enlarge the current demo image, we can find that the obtained path is not 100% compatible with the selected region. In the tolerance option that determines the adaptation error, in The make work oath setting window, press and hold the Alt key on the keyboard, click the tool icon to select the path to be converted to. The make work path dialog box is displayed, The tolerance option, the only setting item, determines the error range allowed by the conversion process. The value range is 0.5-10, and the Unit is pixel. The smaller the value, the higher the conversion accuracy, the more nodes on the obtained path. By default, this value is 2 pixels. TIPS: Generally, you do not need to change the default value. It is enough. If the node is not enough, you can add it in future operations. This avoids unnecessary detours. Create and delete a path layer:Create a path layer and delete a path layer on the rightmost side of the tool icon at the bottom of the path control panel. 　　5. The new path layer tool is used to create a new path layer.. Click this tool to add a new path layer in the path control panel. Like other similar tools, if you press and hold the Alt key on the keyboard and click the new path layer tool icon, the setting window is displayed. The setting window displayed here is the new path setting window, there is only one configuration item, name, which is used to set the name of the currently created path layer. If you need to change the name of an existing path layer, you can use mouse to double-click the left mouse button in the path layer list bar in the path control panel to pop up the new path settings window for renaming. Another function of the new path layer tool is to quickly copy the path layer. If you want to obtain a copy of an existing path layer, you can directly drag the list of path layers to the new path layer tool icon, after the mouse button is released, you can copy the path layer. We get a new path layer named [Path 1 copy, with the same content as pqth 1. 　　6. The delete path layer tool is used to delete a job.. To delete a useless path layer, you can select this layer and click the delete path layer tool icon. Of course, you can also directly use the drag operation to delete the path layer. Only one dialog window will appear for you to confirm, but one will not. II,Right-click the path control in the menu Similar to the channel control panel, you can use the mouse button to click the small triangle button at the top of the path control panel to bring up the hidden path control menu, the menu item can complete all the icons in the path control panel. Some of the options have the same functions as the tool icon in the path tool icon area described above. Displays the list of all menu function options of the path control menu. This includes creating a path layer, hiding a path, copying a path layer, deleting a path layer, converting a selected region to a path, converting a path to a selected region, and filling in the path area, outline the path boundary, set the CIDR path Clipping Path, and set the path layer thumbnail display option palette options. Most of the functions in the path control menu are similar to those in the tool below the path control panel mentioned earlier.
