DPI indicates the resolution, which is the number of points per inch in length. DPI can be subdivided into horizontal resolution and vertical resolution. For example, if the horizontal resolution of a 1 inch * 1 inch image is 100 dpi and the vertical resolution is 50 DPI, it divides horizontally into 100 segments per inch, vertically into 50 segments per inch, just like a grid on a square meter. this figure has 100*50 = 5000 grids in total, with a total of 5000 pixels. since the horizontal resol

Pixel traversal in the position of chess pieces in the python hop Series Preface In the previous blogs, we introduced and practiced color recognition, template matching, and other positioning methods of pawns, this blog will verify the pixel Traversal method used in the most popular jump plug-in on github. Method description The essence of pixel traversal is colo

Photoshop make pixel painting (text) Source: Pacific Internet Author: Exang First of all, I am a rookie, in recent days to do some pixel map, got some friends praise, in this to thank you for my support. A lot of friends want me to do a similar tutorial things like to understand the pixel rendering method, I also just touch the

When we design interfaces and Web pages, we often encounter graphics drawn in Photoshop, although they are vector graphs, but after amplification or there will be a lot of imaginary edges, blurred place, in the magnification, narrowing, rotation after the virtual edge become more serious, or in the AI to draw the exquisite vector icon glued to PS will become false, The work that we have worked so hard to do is "burnt", which is not allowed in our eyes, and we have to make each

First, point Vs PixelIn iOS, when we use frames such as quartz,uikit,coreanimation, all coordinate systems are measured by point. The system will help us deal with point-to-pixel conversions when actually rendering to settings.The benefits of doing so isolate the change, i.e. we do not need to focus on whether the current device is retina after the layout, and can be laid out directly in a set of coordinate systems.In practice we need to keep this in

We have learned how to draw a graph (triangle) on the screen of DirectX 11, which involves the coloring tool. We just used the method, but didn't explain how the coloring tool works, what is a shadow? Today, let's take a look at what it is !!! Because DirectX 11 contains a variety of coloring devices, some of which are used in some advanced applications, as a beginner, first, you can understand the vertex coloring tool and the pixel coloring tool. If

Basic mobile phone resolution knowledge (DPI, DIP computing) 1. terms and concepts Terms Description Remarks Screen size) It refers to the actual physical size of the mobile phone, such as the commonly used 2.8 inch, 3.2 inch, 3.5 inch, 3.7 inch Motorola's milestone mobile phone is 3.7 inch Aspect Ratio (width/height Ratio) Refers to the actual physical size width/height ratio, divided into long and nolong Milestone is and belongs to long Res

The layer-3 Texture of D3D is rendered by the pixel shader YUV420P and textureyuv420p Briefly record some highlights of YUV420P rendering with Texture over the past two days. During video playback, sometimes the decoded data is YUV420P. Surface can render YUV420P by setting parameters, but Texture does not seem to support direct rendering of YUV420P. Surface usage seems to be relatively simple. It is usually used to display data. If Texture is used, m

　　Before you learn the contents of this chapter, be sure to hold the color basics of the lesson in front of you. 　　by learning the basics of color, we know that each pixel has a corresponding brightness, this brightness and hue is not related, the same brightness can be either red or green, as in black and white (grayscale) television, like the image of a single gray can not determine whether it is red or green. therefore, the brightness and hue of t

In three steps, use HTML5+JS to implement the pixel Thunder Image Generator HTML5 's canvas gives us a lot of space, but the pixel style avatar builder just uses the method of drawing squares. Draw a pixel avatar, as long as three steps, 1, solve the pixel point, 2, solve the relationship between the

Tutorial Editor: We say here "pixel painting" is not the corresponding vector map of the dot-matrix image, pixel painting is also a dot-matrix image, but it is an icon-style image, more emphasis on the clear outline, crisp color, almost no mixing method to draw smooth lines, So often used in the. gif format, while its modelling comparison cartoon, get a lot of friends love. If you use the interpolation to c

After running the code to move the position of the mouse at will, you can display the mouse coordinates, do not occupy system resources JS get the mouse coordinates, get the typical example of the mouse pixel, run this page, move the mouse at will, the location of the mouse can be displayed in due time, do not occupy the system resources. nbsp; nbsp; ;nbsp; nbsp; nbsp; [Ctrl + a full election note: If you need to introduce external JS need to refres

This time do not worry, we use the PS "Storage for the Web and device format" can hit the effect we want! 1th step: Find the picture you need to adjust → look at his details → as shown in the following figure 2nd step: Use PS to open the picture → file → save for the web and device format → as shown in the following figure 3rd Step: Select jpeg→ adjust quality → corresponding to the lower left corner of the file memory size → as shown in the following figur

The tutorial introduces the method of making smaller pixel heads. Because there are fewer images, the difficulty of making them is much greater. The author of the various parts of the introduction is not very detailed, the production time does not seek the same effect, roughly the same can be. Final effect 1, first we build a 100x100 of paper. If you do not adjust the point, you can click "Image"-"properties" to adjust. 2, we use Magnifier, enlarge 6

Final effect Diagram 1. Create a new 50*50 file (in pixels). 2. Input text, color random, font casual, remember to eliminate the sawtooth way must choose "None", and then the text layer grid. As shown in Figure 1. Figure 1 3. Select "General" under "edit"-"preset" to set "image interpolation" to "near (faster)." As shown in Figure 2. Figure 2 Remember, after the finished to restore this setting back to the "two cubic (better)", otherwise, hehe, later small map larger picture, it is not fun

Dispose a bit, otherwise it will not update oh.The specific code is: if (picturebox1.image!= null) {PictureBox1.Image.Dispose ();}Here is another piece of code, so that you can modify a picture of the pixel value, and generate a new picture. So we can make our own code to create cool GIF. (such as the effect of a gradient from one picture to another picture.) ）The processing of the image should be used to Bitmap, not image, so first know their mutual
