End Google Ads 201810 - BS.net 01 --> My app (which is part c++/cli and part c#) generates bitmaps on the fly, and they exist in memory initially as arrays of unsigned char (width * height * 3 bytes (rbg)).

I need to be able to crop, resize, rotate (90, 180 degrees), mirror and flip these images in an efficient way.

I've previously used GDI+, but GDI+ has some serious threading issues (although it allows multiple threads, only one thread per process actually gets executed by GDI+ at a time).

So i need a replacement image processing library. I looked at CImg, but internally it organises data into separate arrays, one per colour channel, which would make it a headache to get my data into and out of the library.

is anyone familiar with any other libraries which will meet my needs? could be c# or c++, it doesn't really matter.
