One way is to open the file and parse the BMP format to find the color. You don't need anything else but Dev-C++ for that. There are various websites that give explanation of format, this might be a good starting point: http://en.wikipedia.org/wiki/Bitmap I don't know if you're using pure Dev-C++? For example if you use it with wxWidgets plugin (wxDev-C++) you can use wxImage class to load image from file into memory and then inspect it. Other than that, perhaps SDL_image library is also a good candidate. As for IrfanView, maybe you should check it's documentation, maybe it has some ways to run it from command line and it would output some info about images. But that still sounds like a weird idea. -- Milan Babuskov http://www.guacosoft.com
