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

Image processing-about pixel coordinate matrix transformation (translation, rotation, scaling, miscutting), image processing Matrix Introduction The coordinate transformation matrix is a 3*3 matrix used to perform coordinate changes on the image and transfer the original coordinate point to the new coordinate point, because an image is composed of a dot matrix and color information at each point, the conversion of the sitting mark is to move each

Use the text in Flash with a very small font size? Of course, the first time to think of 04 such a classic pixel font (PIXEL font) but with the PIXEL font disadvantage is not no, the first is the need to set a fairly accurate, otherwise the word or to paste (need to be accurate to 0.1 pixel adjustment, very annoying) f

From: http://blog.csdn.net/hxgqh/archive/2011/02/23/6202001.aspx You can obtain the pixel value for more flexible image processing. In opencv, you can add a cvscalar struct to the cvget2d () and cvset2d () functions.In opencv, The cvscalar structure is:Typedef struct cvscalar{Double Val [4];}Cvscalar; Four double-type variables will not be forced type conversion during algorithm processing and reduce the accuracy.Let's take a look at the definition o

Focus speed You should take some actions to make the program run as much as possible. First, locking a surface is not the fastest, so you need to try to lock the smallest rectangular area on the surface that you want to operate. For many operations, including simple pixel rendering demo programs, you should lock the smallest rectangular area. Second, in the 640x480X16 mode, the spacing is always 1280 bytes. You should try to consider whether there is

HLSL is basically written in the language of C, but I personally feel that the most difficult way to get started is to pass in the parameters of the two functions of the vertex shader and pixel shader completely in the C language.The following is an example of your own understanding in the simplest HLSL effect framework.uniform extern float4x4 GWVP; struct OUTPUTVS{FLOAT4 Posh:position0;FLOAT4 color:color0;}; Outputvs Colorvs (float3 posl:position0, F
