Flip operation, etc., if the image library support, is relatively simple, when click the button for various operating various image manipulation (call)

CodePudding user response:

flip BMP is simple, the highest one line and the bottom line of data exchange, step by step until the middle, stop,

CodePudding user response:

Use gdi +

CodePudding user response:

Built environment using OPENCV, or BMP images per-pixel operations

CodePudding user response:

CxImage library is an excellent image manipulation libraries, it can quickly access, display, conversion of images,
Directly using the open source library is a kind of function is complete
