This test works for me: ~~~~ #include "CImg.h" using namespace cimg_library; int main() { CImg::save_empty_cimg("test.cimg",1000,1000,1,3); CImg img(500,500,1,2,0); img.rand(0,255); img.save_cimg("test.cimg",0,128,128,0,0); CImg::get_load_cimg("test.cimg").display("test.cimg"); } ~~~~

The `pattern` parameter has always the same meaning. It's a 32bits integer (`unsigned int`) whose bits define the pattern of the drawing. - If all bits are set to `1`,...

I've done this commit : https://github.com/dtschump/CImg/commit/9c1c24d9d7fa743047382d3c0a40e9724ddb987a Could you check if that solves your problem, as intended ? I don't have MSVC right here on my computer.

Humm. These error messages do not help a lot ! I don't know what I could do then :(
