Take the 2-minute tour ×  I'm grabbing a portion of the screen
and scanning through the pixels for a certain color range.  I
looked at MSDN's Capturing an Image example and know how to use
the functions.  I can get the bits into an array, but I'm not
sure how to do it in such a way that I can loop through it as I
would an image. A pseudo-example (which I'm sure is way off):
for ( x = 1; x <= Image.Width; x += 3 )     for ( y = 1; y <=
Image.Height; y += 3 )         red = lpPixels[x];         green
= lpPixels[x + 1];         blue = lpPixels[x + 2];  That's
basically what I want to do, so if red, blue, and green is a
certain color, I'll know what coordinate it's at (x, y) in the
image.  I just don't know how to use GetDIBits in such a way,
and how to setup the array appropriately to be able to
accomplish this.  share|improve this question add comment  4
