I tried writing a custom decoder for png files using WIC. I have a problem in displaying the palette type images. Can any one help me to understand the initialization of IWICPalette with the color table entries. I use InitializeCustom(colors, numcolors) for initialization of the IWICPalette. color - represent the WICColor array. For a 1bpp indexed palette type image what should be the value of numcolors? what should be the size of the WICColor array? How do i store the RGB triplet values for each index? |
