One of the errors in MCTRL are icons with not working trancparency!
I am trying to collect informations about image trancparency in the windows environment.
There is the rule, that the color of the upper left pixel is the trancparency color.
I have also found the rule, that the magenta parts of the image are transparent.
Last but not least are there 32-bit icons/images with alpha channel.
In Pelles C's icon editor there is a special color named screen color and in 16 color mode a special pixel with a cross in it (not clear, how to set such a pixel).
Can someone bring some light on this, please? Which OS supports which methode?
