But when I open the image with Gimp, it tells me that the image is RGB

Seems that Dot.net can not handle files of Indexed Pixel Format as well as
other types of formats.
Given a file or and Image of type Indexed Pixel Format is there a method to
convert it to some other pixel format?
Thanks

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
