Thread: poker game

Hello, I'm thinking of making an online poker game, it will have simple 2d graphics. I have never made a game before, and I don't know any opengl/directx stuff only pure win32. Do you think it is feasible to do this in pure win32 code?
The chips and cards need to be capable of smoothly moving across the table. My first problem I have hit is that how do I make certain pixels of my bitmaps not be drawn?
The table is not all one solid color, so I can't just set the background of the chip to a solid color.
Because if I have a square bitmap with a circle in it, how do I make it appear like a circle and not a square? I hope you understand what I'm trying to ask, because I'm having a hard time explaining it.

thanks
