Is there a way to convert cartesian or polar to pixel coordinates? like (x,y,z) to (RGB) or (x,y) to (RGB) or (r,theta) to (RGB)?

I wonder there's a misunderstanding...

cartesian and pixel coordinates are related to the FOV (field-of-view) of the image in the whatever system coordinates, and pixel sizes.

RGB is related to the color scale, or color specification of the image. See this doc.

Could you better explain your question?

I have a complex array (x+iy) and I wand to create an image out of it, So from a pair of point (x,y) to pixels that represents an Image
