Note: This library is is stable and contains no known bugs. I will continue to fix any bugs and test against the platforms as they are updated.
Linux/Mac
Windows
Cross-platform screen and window capturing library . . . this is made to be lightweight and fast. see the Exmaple folder for a demo
linux: sudo apt-get install libxtst-dev libxinerama-dev libx11-dev libxfixes-dev
- Windows 7 and Up
- MacOS
- Linux
The image format is raw BGRA 32 bits per pixel. Alpha is unused!
The data exists like this if you were to march through with a for loop [A,R,G,B], [A,R,G,B], [A,R,G,B]. For a read on why this is check out the post here post here
