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
