AlphaDistribution Class Reference
Detailed Description
An implementation of alpha distribution methods. This implementation only works for textures with 8-bit channels.

Public Types | |
| enum | Method { METHOD_ERROR_DIF , METHOD_PYRAMID } |
Static Public Member Functions | |
| static void | FixAlpha (Method method, unsigned char *alpha, int width, int height, int spp=1) |
| Fixes the alpha values of an image with the given width and height using the specified method. If the image will be used with alpha-to-coverage, the spp parameter should indicate the number of alpha samples; otherwise, it should be 1. | |
| static void | FixAlphaRGBA (Method method, unsigned char *image, int width, int height, int spp=1) |
| Fixes the alpha values of an RGBA image with the given width and height using the specified method. Only the alpha channel of the image is modified, the RGB values are not altered. If the image will be used with alpha-to-coverage, the spp parameter should indicate the number of alpha samples; otherwise, it should be 1. | |
| template<typename SAMPLE_MASK_TYPE = unsigned char> | |
| static void | GenerateSampleMaskTexture (SAMPLE_MASK_TYPE *sampleMask, unsigned char const *alpha, int width, int height, int spp) |
| Generates a sample mask texture from the alpha values of an image with the given width and height. This sample mask texture can be used with the original texture for handling alpha-to-coverage. The spp parameter is the number of alpha samples that will be used. | |
| template<typename SAMPLE_MASK_TYPE = unsigned char> | |
| static void | GenerateSampleMaskTextureRGBA (SAMPLE_MASK_TYPE *sampleMask, unsigned char const *image, int width, int height, int spp) |
| Generates a sample mask texture from the alpha values of an RGBA image with the given width and height. This sample mask texture can be used with the original texture for handling alpha-to-coverage. The spp parameter is the number of alpha samples that will be used. | |
