Writing to an Image

[Principher]

I have decided to try to learn programming for my Amiga 1200. Currently I have started with ECS graphics programming.

However I have a problem. I grew up with VGA chunky graphics and not the Amiga's planar graphics and as such I have have a bit of a hard time figuring out how to write a pixel to an image. Ofcourse I could just use WritePixel, but since this is a function and not a macro it is way too slow for writing lots of pixels. Can someone explain how to write a pixel at location (x,y) in a NxM image with D bitplanes in a way so that I can construct a macro for the job?

I have tried searching google for help, but have not been able of finding the right combinations of words

Thanks in advance

Thanks, I will look into those two options. Didn't think of the possibility of there being a chunky to planer converter function.
