How to convert binary data to BMP format?
I acquired raw data from a camera 320x240 pixels per frame. I have one binary file containing 3600 frames. I need to write a program in C++ to take the file and convert each frame to a BMP image.

Hi,

Chances to be wrong, as I have a sequence of assumptions.
As you  have 3600 frames, I understand it is a clip, a short film in 320x240 pixels format, BTW a typical small format film. Most film cameras or photo cameras capturing films record the films in mpg format.

If these assumptions are correct, what you need is to convert a MPG or AVI film by exporting each frame to a series of BMP image format. As you tell abot a raw file it icould be also an uncompressed file.

Whatever you have, you must know what format is, to chose the right codec to decode the film. As soon you read the file, your program can convert frame by frame to BMPs. This will be a complicated task, if you are not an experienced graphics programmer. And a tedious task.

A practical way to do it is simple play your film and, at same time, run a program that capture the image at a appropriated rate, say 15 or 30 mframes per second. Such capturing program can be found at
http://www.codeguru.com/cpp/g-m/bitmap/capturing/article.php/c4919/

Things will be simpler if you know the raw film format. And much more simpler if the raw file isn't compressed.

You can share more information with us, if you have more.
