Syntax:

b2dGetImagePaletteColorR:Int(imageHandle:Int, index:Int)

imageHandle : Int
index : Int

Int

Summary

Returns the red component of a palette entry, 0 to 255.

Takes imageHandle and index (0 to 255).

Returns the red value, or 0 if the handle or index is invalid.

This reads the stored palette, not the animated one - it returns the entry as loaded or as last set by b2dSetImagePaletteColor, and is unaffected by any cycling or fading currently running.
