Effect Chart: 1, new file: 400*400, the background is white. Then create a new layer. 2, set the foreground color is green (reference value: #51A9A1), with the elliptical marquee tool, draw an oval selection, fill the foreground color. 3, select---modify---contraction, (parameter is 30 pixels) 4, select---feather (parameter is 30 pixels), OK. Then the reverse, press DELETE key Delete, the result is as follows.

1, a new 895X307PX layer, the resolution is 300, the background color is white, color mode is RGB. 2, open the character material, drag to just new layer above. 3, create a new layer, using the pen tool to circle the top half of the picture, you need to have a point of curvature, and then use the shortcut keys Ctrl+enter to make it into the selection. 4, select the Gradient tool, set the gradient color, and the eyedropper tool to adjust the gradi

Original Effect chart 1, first press CTRL + SPACEBAR and click to enlarge the picture, at this time will find the face of mm more rough, so we can choose "Smudge tool", in the property bar to set the strength of "10%", and then carefully in the face of mm smear, reduce facial skin roughness, so that the color looks even more, as shown in the picture. Before smearing: After smearing: 2, select "Sharpening Tool" in the toolbox, and select "Soft angle 13 pixel" nib in the p

You do not need to map the image. It is the simplest and best-performing method. 1. Use the magic wand to select the background of the red part. CTRL + ALT + D (the range is slightly larger, depending on the image resolution) 2. Press Ctrl + u to display the color window and press Ctrl + 1 to adjust the color and saturation and brightness to an ideal value (sometimes Ctrl + ~ Fixed Multiple times) Step 2 can also be used with "1.

The earth coordinate system is the basic Coordinate System of the Earth measurement. It is often used for the computation of earth problems, studying the shape and size of the Earth, preparing maps, positioning and operations for rocket and satellite launch and military aspects, it is inconvenient to directly use it for project construction planning, design, and construction. Therefore, it is necessary to convert the Earth coordinates on the sphere to the plane according to certain mathematical

Problem DescriptionIn Diagon Alley, there are only one wand-seller,peeling gold letters over the door read ollivanders:makers of Fine wands s Ince 382 BC. A single wand lay on a faded purple cushion in the dusty window.A tinkling bell rang somewhere in the depths of the shop as they stepped inside. It is a tiny place,empty execpt for a single spindly chair which Hagrid sat in to wait. Harry felt strangely a

In the post processing of the photos, we often use Photoshop to extract the characters from the photos in order to achieve special effects such as background replacement. The use of Photoshop to extract the characters of a lot of methods, we first change the background of the photos of some small instances, to summarize the article describes the Photoshop four ways: One, the tool method--skillfully replaces the background with the magic wand tool Tw

Coordinate System and Projection Transformation and Its Application in ArcGIS A batch of data needs to be processed recently, which involves the content of coordinate transformation. I will share my personal data collection and experience. please correct me if I have any shortcomings! First, I would like to raise the following questions:Is there a coordinate conversion problem? Is there a problem with projection conversion? What is the difference between coordinate conversion and projection co

1. Magic wand method-the most intuitive methodApplicability: the color difference between the image and the background color is obvious, the background color is single, and the image boundary is clear.Method intent: remove the background color to obtain the image.Method defect: it is useless for scattered hair.Usage: 1. Click "magic wand;2. Check the "magic wand"

Tool Method--Use magic wand tool to replace background skillfully Knowledge Tip: Magic wand tool is mainly to enable users to choose a color consistent area (for example, a red flower) or the background of the more monotonous picture, without having to track its contour. The Magic Wand Tool chooses a color range that can be controlled by the value of the error r

to abstract an elliptical body similar to the earth. The elliptical body has the following features: it can be quantitatively calculated, features long half axis, short half axis, and eccentric heart rate. Because the time, method, and region of the elliptical body are different, the results are often inconsistent. Therefore, there are many types of Earth

1 Emphasis on map projection knowledge Concept of projection In mathematics, projection refers to establishing the correspondence between two surface point sets. In cartography, map projection is to establish a one-to-one correspondence between the surface and the projection plane, that is, to study how to express the earth surface to the map plane.Importance-correct map projection is the basis for combining/overla

Geographic coordinate system and earth coordinate system (reproduced) Geographic coordinates: spherical coordinates. The reference plane is an elliptical sphere. Coordinate unit: longitude and latitudeCoordinate: plane coordinate. The reference flat area is the coordinate unit of the horizontal plane, including meters and kilometers.The process of geographic coordinate transformation to the Earth coordinate can be understood as projection.

"Lasso Tool" is a selection tool, when not used a lot, mainly used in processing bitmaps. When you select the Lasso tool, the magic wand and its options and polygon mode appear in options, as shown in Figure 2-2-30.

Tips in Photoshop, the most original approach is to use the Magic Wand Tool magic Wand in the background of the adjacent color selection to delete, and then use the Eraser Tool Eraser tool to carefully erase the rest of the background of the remaining broken branches. Alternatively, use the Lasso lasso tool to outline the main part of the image, then reverse the selection and delete the background. We summ

For a long time, there are always many friends who cannot fully understand the concepts of geographic coordinate system and earth coordinate system. Recently, I saw an article about them on the Internet, which I like very much. So I want to forward it here, hoping it will be helpful to the drawing friends. Geographic coordinates: spherical coordinates. The reference plane is an elliptical sphere, and the coordinate unit is longitude and latitude.Coor
