Hi TenaC
Yes you can. You need to put your byte array into a memblock, then use the memblock command
CreateImageFromMemblock.
If you look at the help page for this command there is an example with code.
The above command is for bitmaps. There is also a command CreateImageFromPNGMemblock that does the same for PNG's.
I would guess as long as your .Net image is either a bitmap or PNG, you might be able to get the raw bits, put them into a memblock. Maybe you could use a MemoryStream or something like that to save the image to? Then read the bits from the MemoryStream into an AppGameKit memblock, then use one of the above commands to create an AppGameKit image from that?
