(Open GL) Making a colour transparent

[Blessman11]

I'm trying to create a side-scroller and I need to make a colour of my bitmap transparent. How do I go about doing this?

In most 2d graphics the color 0xff00ff is transparent.

would that work for bmp images

Yes, it works for me, but you'll have to look up how to do a masked blit.
