Question

I had assumed that Gdiplus::Bitmap::FromFile returns NULL if the file is not a valid image, but it returns a non-NULL even if I pass it a doc file, for example. There doesn’t seem to be an IsValid method for Bitmap, or anything similar.

So how do I know if Gdiplus::Bitmap::FromFile has really loaded a valid image?

Answer 1

It turns out that Bitmap::GetLastStatus() is what I was looking for, it returns Gdiplus::Ok if the load operation succeded, or an error code if it failed.
