P glPixelMap 324 glPixelMap glPixelMapfv, glPixelMapuiv, glPixelMapusv: set up pixel transfer maps. C Specification void glPixelMapfv( GLenum map, GLsizei mapsize, const GLfloat *values) void glPixelMapuiv( GLenum map, GLsizei mapsize, const GLuint *values) void glPixelMapusv( GLenum map, GLsizei mapsize,const GLushort *values) Parameters map mapsize values Specifies a symbolic map name. Must be one of the following: GL_PIXEL_MAP_I_TO_I, GL_PIXEL_MAP_S_TO_S, GL_PIXEL_MAP_I_TO_R, GL_PIXEL_MAP_I_TO_G, GL_PIXEL_MAP_I_TO_B, GL_PIXEL_MAP_I_TO_A, GL_PIXEL_MAP_R_TO_R, GL_PIXEL_MAP_G_TO_G, GL_PIXEL_MAP_B_TO_B, or GL_PIXEL_MAP_A_TO_A. Specifies the size of the map being defined. Specifies an array of mapsize values. Description glPixelMap sets up translation tables, or maps, used by glCopyPixels, glCopyTexImage1D, glCopyTexImage2D, glCopyTexSubImage1D, glCopyTexSubImage2D, glDrawPixels, glReadPixels, glTexImage1D, glTexImage2D, glTexSubImage1D, and glTexSubImage2D. Use of these maps is described completely in the glPixelTransfer reference page, and partly in the reference pages for the pixel and texture image commands. Only the specification of the maps is described in this reference page. map is a symbolic map name, indicating one of ten maps to set. mapsize specifies the number of entries in the map, and values is a pointer to an array of mapsize map values. The ten maps are as follows: GL_PIXEL_MAP_I_TO_I Maps color indices to color indices. GL_PIXEL_MAP_S_TO_S Maps stencil indices to stencil indices. Chapter 14
