Direct2d 1.1 Development Notes Special Effects Article (3) Simple pixel shader Special Effects

(For more information, see the source) 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

YUV pixel format

1 Overview YUV is a color encoding method. It is developed to be compatible with black and white TVs.

iOS dev > Learn-how to draw 1-pixel lines correctly

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

OpenGL pixel format Management

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),
