How to get image from the screen and then save it to a file?
I want to clip a rectangle box from the desktop and save the pixels as an image. Then save the image to a file.
So there are 2 questions:
1. what's the efficient way to get the pixels in a rectangle box on the screen? Using GetPixel in for loops is the only thing I know.
2. I want to save the image to a file. I guess saving it to .bmp is the easist, but what is the format of bmp? It would be better if I can compress it in any way with a few lines of code, BTW, I am programming in C++.
Thanks in advance!
