Photoshop Tutorial 06:photoshop6 reversal of the universe

Tutorial reverse? It's not that dramatic, is it? wrong! Photoshop really can! Let the corn do this young tell you. It is rare that the picture meets the requirements at the outset. When you copy an object from a picture to another image, you often enlarge or shrink it. You may also want to tilt the line to the level, as well as up and down, flip around. In Photoshop, you can do this by just clicking a few mouse clicks or by performing a few simple commands. It's not easy, let's start now.

Reset Size

Photoshop can easily change the size of an image or any of its objects. There are two options: Resize the image or reset the canvas. The former is the enlargement or reduction of the image itself. The latter is to enlarge or shrink the work area, still let the image float in it. Typically, you use the latter only if you need more work space around the object and you do not want to shrink the double-click image.

Resize an image

To resize the image, you can select, command, and open the dialog box shown in Figure 6-1.

Figure 6-03

(1) pixel size--here, it shows the size of a single front image, you can change the size of the image by setting the width and height of the image. If you select the constraint scaling option, the chain to the right appears, indicating that the width and height of the image will always remain the original proportions.

(2) Document Size--here, you can view the dimensions of the image to apply printing, or you can change the print size by adjusting the width, height, and resolution. The units you can select are percentages, inches, centimeters, pica, columns, and dots. If you keep the resolution of the image unchanged, change the pixel size and document size when setting the width or height of one of the option groups, the width and height of the other option group also change.

(3) to redefine the image pixel--when changing the image size, Photoshop will redistribute the original pixel color to the new pixel in a certain interpolation way. The optional approach is shown in Figure 6-4. The two cubic cubes are the most accurate way of distribution.

Note: Changing the size of an image can sometimes cause image quality to be affected.

Reset Canvas Size

The canvas size command allows the user to modify the working space around the current image, that is, the size of the canvas. You can also crop the image by reducing the canvas size. When the canvas size is enlarged, the newly added space will be populated with the current background color. So before you change the size of the canvas, make sure the background color in the toolbox is the color you want. White is a common color.

Click, Command, and eject the dialog box shown in Figure 6-7.

Figure 6-07

The same dialog box as the image size described earlier. You can choose the metric system you like from the pop-up dialog box. Enter the size of the canvas you want to change. Photoshop Displays the size of the new file.

In addition, the canvas size differs from the image size in that it is possible to use anchor points to determine where the image is placed on the canvas. As shown in Figure 6-8, after clicking the upper-right corner, the image size does not change, just because the canvas size is larger, the original image also runs to the upper right corner. As shown in Figure 6-9.

Change the size of the selected area

You can also change the size of the selected area. To do this, first select the object or the image you want to resize by using the most convenient tool. When the selection box is active, select,, and command. As shown in Figure 6-13, a window that resembles a trim box is placed around the selected object, and a control handle anywhere around the box is dragged to change the size of the selected object. If you drag the slot while holding down the SHIFT key, you can also maintain the height of the object's width ratio. If you have a handle on the side of the Guodong box, you can stretch or shrink the height or width of the selected area.

Rotating

There are many images in the process of processing, in order to more efficiently and easily operate, need to rotate. Photoshop provides a powerful and accurate selection tool. Execute, Command, and its menu as shown in Figure 6-16.

Figure 6-16

If you don't rotate the canvas at right angles, you can select,, and then open the dialog box as shown in Figure 6-20.

Figure 6-20

In the dialog box, enter the angle value you want to rotate. If you cannot exact a specific value, you can set a value first. And then constantly undo or reset. Select and to determine the direction of rotation, click Finish. Flipping the image is as simple as real life.

Mirror Flip

Flipping is actually similar to looking in the mirror, and the image after the flip is the image behind the mirror. You can flip horizontally, as shown in Figure 6-24. You can also flip vertically, as shown in Figure 6-25.

Figure 6-24

Figure 6-25

Mirroring flips and rotates differently, it changes the direction of the image up or down or left and right. Of course, sometimes we have to rotate the image as well as the image to get the image we need.

Transform a Selection object

The preceding can be either for the entire canvas or for the selected object. You can only apply the entire image to the selected object, as described below.

Click, command, and drop down the menu as shown in Figure 6-28.

Figure 6-28

The rotation and scaling are similar to the commands under the canvas, and I'm not going to go into detail here. The following are mainly about chamfered, twisting, and perspective.

(1) Skew is not only tilted to a certain angle, it can also distort the image, stretching, and deformation. Like a piece of putty, you can change it arbitrarily. It allows the selected object to distort in all possible directions, and we can do this simply by dragging the control handle and dragging the selection area. Just press ENTER when you are done. As shown in Figure 6-29 is a picture of an effect after a diagonal cut.

Figure 6-29

(2) Distort the selection area. All the transformation tools are similar, but there is a subtle difference in how the selection area is changed. For example, zooming and skewing can change the selection area, but the twist command does not change the size of the image, but rather the extrusion and stretching of the graphic love you with. As shown in Figure 6-30.

Figure 6-30

(3) Change the perspective effect of the selected object. The pivot command is one of the most commonly used commands in Photoshop's tool library. To create an image that is nearly as large as a small effect, the perspective tool is the most appropriate. Its movement is very intuitive. When you stall a control handle at a vertex, its diagonal is mirrored motion--the mirror handle of the diagonal when you click a control handle and drag the mouse from the selection area will also mirror the selection of the principle area. Conversely, if you drag an anchor point into the selection area, the mirror handle of the diagonal will also move inward. As shown in Figure 6-31.

Figure 6-31

The difference between perspective and deformation is that the deformation can only deform one vertex of the selected region. When the perspective drags one of the top corners, it adjusts the two corners automatically while mirroring changes.
