As we know, before the CS5 (version number), it is very difficult to achieve pixel-level accuracy with the AI vector tool. Why? Because unlike PS image processing software, a raster based image processing software (that is, directly orien
What is the basic element of a color picture?
To put it bluntly, an image consists of the basic thing is binary data, its capacity size in essence that is the number of binary data. A YUV422 image of a 1920x1080 pixel, the size of which is 1920x1080x2=4147200 (decimal), or 3.95M. This size is related to the number of pixel points and the storage format of the data. The following describes the relationship b
In the book 3D Mathematical Fundamentals-graphics and game development, we see the concept of pixel-to-width ratio. Of course it's good to understand that pixels are squares, so the pixel-to-width ratio is 1.
For pixel aspect ratio details, please refer to msdn:https://msdn.microsoft.com/zh-cn/library/cc294571.aspx, I will parse the meaning of the formula after q

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
Brief introduction:Always understand the common units in Android is not very thorough, share under today. What's not in place, welcome to point outMeaning:1, Screen Size: Physical size (cell phone diagonal size, such as 4.7, 5, 5.5 inches of mobile phones)2. Density (dpi): the pixels shown per inch3, Pixel (px): The size measured on the real screen4, DP: screen width and px of a ratio, on the large-screen
Android development unit, 1DP indicates 1px length at a screen point density of 160ppi.Since the Android device screen is numerous and cannot be developed individually for each screen, the number of pixels on different screens is calculated using the formula px=dp* (ppi/160).Example: HVGA screen 320*480, generally 3.5 inch, calculate the point density is √ (320^2 + 480^2)/3.5 = 164, approximately equal to 160,1pd=1pxWVGA screen 480*800, press 3.8 inch screen count, point density Yes (480^2 + 80
As long as the digital signal processing circuit, there must be a clock signal. In the LCD panel, the pixel clock is a very important clock signal. The frequency of the pixel clock signal is related to the working mode of the LCD panel, the higher the resolution of the LCD panel, the higher the frequency of the pixel clock signal. Within a row, the number of

This time we implement a custom transformation.
The implementation of direct2d custom transformation shader models requires the implementation of HLSL (high level shading language.
HLSL is a shader implementation, but HLSL can only be used in d3d.
Shader is described as a short program executed by the video card, which can be executed efficiently (in parallel.
Never learned? It doesn't matter. I don't know it either, but I won't explain it in detail here
1 Overview
YUV is a color encoding method. It is developed to be compatible with black and white TVs. In Modern Color TV systems, three-channel color cameras or color CCD cameras are usually used to retrieve images, and then the acquired color image signals are divided by color, respectively amplified and corrected to obtain RGB, then, the Brightness Signal y and two color difference signal R-Y (U) and B-Y (v) are obtained through Matrix Transform circuit, and the three signals are encoded respe
Editor's note: Pixel style is the favorite of some artists, but also the game impression of many students. Today to share a simple and practical pixel painting tutorial, teach you to draw a personalized pixel and blue room, the process is very meticulous, beginners can learn, finish can also draw their own pixel wind b
Some of them were very large, the quality is very good HD PNG picture, after reduced to icon but became miserable (the details of the icon loss of serious) and when we go to see those professionals made icon, but found that the other side of the production of the icon size is small, but the details are kept very good, Is there any skill in this? Today, share an article about using Photoshop CS6 grid alignment to draw HD icon.
Photoshop CS6 has been well received since its release, and attentive
Recently I have studied pixel-level touch processing. Sometimes we use an irregular image as a button. This irregular image is a PNG image of a rectangle, it is very likely that the actual effective display content of the image only accounts for a small part of the entire PNG image, and most of the remaining content is the transparent area of the PNG image. We want to filter out this transparent area, A button response is effective only when the actua
When designing Web pages and program interfaces, most designers are worn out to ensure that each pixel's color, texture, and position are accurately presented. Accidentally, some of the most commonly used operations such as moving, rotating and pasting will make your hard work to naught. However, if you can make some small changes to your workflow, you can always keep the quality of the work in the project.

The pixel padding rate refers to the number of pixels that the graphics processing unit renders per second, in mpixel/s (million pixels per second), or gpixel/s (1 billion pixels per second), which is the most common metric used to measure the pixel processing performance of the current display chip.
The rendering pipeline is an important part of the display core and is a set of specialized channels in the

internal values of a pixel color to eight bits in a linear relationship to output to the screen, where red occupies three bits of the second bit, green occupies 3 bits in the middle and blue occupies 2 bits in the highest position. Windows regards the 8 bits as the index value of the logical palette. For example, after the color value of OpenGL (1.0, 0.14, 0.6667) is converted, the binary value is 10001111 (111 in red, 001 in green, and 10 in blue),
The getImageData and putImageData functions are required for Pixel processing in HTML5.GetImageData copies the pixel data in the canvas, processes the acquired pixel data, and finally passesPutImageData paste the processed data to the canvas. The process of processing pixels in the middle is called the batch processing of pixels. Because copying and pasting pixel
There is a way to see if someone is really careful when completing a webpage design. Sometimes the miracle is some small details, some details that are almost invisible to others. What I call "pixel-level beauty" refers to the careful scrutiny of online bars, edges, and border strokes. Instead of using a single line, we should add more details. The details can be a subtle gradient, or just a line of 1 pixel
