C# - get bmp from image

Expert: Hosnieh [Sara] - 10/19/2009

Question
Hi, I've checked that my webcams are standard, and the webcam bit works fine. The problem occurs when I try to convert the individual images to bmps.

If I replace the webcam with a bmp I can alter the bmp by using graphics, so that bit works fine too.

But with a webcam I keep on getting a runtime error saying "Does not refer to object instance"

The way I understand a webcam works it is a camera that takes about 30 pictures a second - because each picture is slightly different it gives the illusion of movement (a bit like a cartoon , but with a stream of camera pictures rather than drawings). So I I could find a way to lock my work to the pictures I would be able to work/alter them as bmps.

Answer
Hello,
I try to help you as much as I can but first I need to know more about your problem.
does your webcam save the picture in any place and you want to alter those picture or you want to get picture directly from the webcam (streaming) and then alter it?
some of possibilities:
if it saves the pic, then maybe it is not bmp and it is in compress format like Jpeg.
maybe the picture is in use and your program cannot alter it.
