    Does PVR image format support indexed image?

    What’s the different between ‘i’ and ‘l’ channel names in PVRTexTool Command-Line tool?

    Hello Xpol,

    indexed images, also know as palette images are not supported by PVR Image formats.

    The ‘i’ channel stands for intensity which is calculated as i=(R+G+B)/3.
    The ‘l’ channel stands for luminosity which is calculated as L=0.2126 R + 0.7152 G + 0.0722 B.

    Thanks,
    Paul
