Image.FromStream() method returns Invalid Argument exception

Question

I am capturing images from a smart camera imager and receiving the byte array from the camera through socket programming (.NET application is the client, camera is the serve

Answer 1

I'm guessing that something is going wrong when receiving the file from the server. Perhaps you're only getting part of the file before trying to convert it to an Image? Are you sure it's the exact same byte array you're feeding the C++ application?

Try saving the stream to a file and see what you get. You might be able to uncover some clues there.

You can also add a breakpoint and manually compare some of the bytes in the byte array to what they're supposed to be (if you know that).

Edit: It looks like there's nothing wrong with receiving the data. The problem is that it's in raw format (not a format that Image.FromStream understands). The Bitmap(Int32, Int32, Int32, PixelFormat, IntPtr) constructor may be of use here. Or, you can create the blank bitmap and blt it manually from the raw data.
