pixels in a DC
I have a question you might have seen before, but I can't find it on the site, so here goes:
Is there a better (i.e. faster) way to access the pixel data in a DC?
In this particular instance, I've got a DC of the screen by using CreateDC, and I'm using GetPixel, then GetRValue etc. on each pixel point. But it's taking too long. Is there a way to access the data that GetPixel is looking at? Will I be able to interperit it?
Any help appreciated,
I suppose you could get a DIB of the DC and access the data in it. In this thread, I responded to someone on how to access DIB data directly.
