It will work for grey image what about RGB images

[Image Analyst]

Yes, it will. Basically you have to know what the format is, since it's not a standard format. Then get the bytes and organize it into and RGB image. For example, are the bytes RGB for pixel 1, then RGB for pixel 2, etc.? Or is it R for all pixels, then G for all pixels, then B for all pixels? Or is it BGR, BGR. BGR, etc. You need to know that. If you don't, then guess. One of them will look right and the others won't.
