The histogram whose parameters are to be set. Must be one of GL_HISTOGRAM or GL_PROXY_HISTOGRAM .
widthThe number of entries in the histogram table. Must be a power of 2.
internalformatThe format of entries in the histogram table. Must be one of GL_ALPHA , GL_ALPHA4 , GL_ALPHA8 , GL_ALPHA12 , GL_ALPHA16 , GL_LUMINANCE , GL_LUMINANCE4 , GL_LUMINANCE8 , GL_LUMINANCE12 , GL_LUMINANCE16 , GL_LUMINANCE_ALPHA , GL_LUMINANCE4_ALPHA4 , GL_LUMINANCE6_ALPHA2 , GL_LUMINANCE8_ALPHA8 , GL_LUMINANCE12_ALPHA4 , GL_LUMINANCE12_ALPHA12 , GL_LUMINANCE16_ALPHA16 , GL_R3_G3_B2 , GL_RGB , GL_RGB4 , GL_RGB5 , GL_RGB8 , GL_RGB10 , GL_RGB12 , GL_RGB16 , GL_RGBA , GL_RGBA2 , GL_RGBA4 , GL_RGB5_A1 , GL_RGBA8 , GL_RGB10_A2 , GL_RGBA12 , or GL_RGBA16 .
sinkIf GL_TRUE , pixels will be consumed by the histogramming process and no drawing or texture loading will take place. If GL_FALSE , pixels will proceed to the minmax process after histogramming.
