68K Dev Question: How do I work with images in C or C++ on the Amiga?

[nyteschayde]

I have been trying to find place that describes how to load an image and present it with code. Things that would be nice to understand:

• How to load an image pre-datatypes
• How to load an image with datatypes
• How to display an image in a regular window
• How to display an image directly to a screen

• Examples on how to do this with <=3.1 would be great
• Examples on how to do this with >3.1 would also be enlightening
• Examples on how to do this with 24-bit images would be welcomed

• What types of images are supported without datatypes? ILBM? Anything else?
• Any info on tools you might use to convert PNGs, JPGs and more to ILBM
• Anything else along these lines

Thanks in advance.

Thomas, do you have any quick examples on how to do what I asked in C or C++? Clearly with datatypes since it would seem that coming up with your own bitmap format or writing a parser for a bitmap would be a waste of time unless you were limited to OS1.3 or (when did they add datatypes? 2.x?)
