hi guys
I am trying to save a frame to disk as a jpeg image. I used the SDL
tutorial, but that program saves the image as a ppm which is not
naturally supported by Microsoft. So how can I save it as a jpeg or
a bmp (a for that windows naively supports?) thanks.

I ran into a similar problem with OS X, and I found two solutions. One
was to us netpbm (windows version here: http://gnuwin32.sourceforge.net/packages/netpbm.htm)
to convert the PPM images to another format after they've been
output. The other option is to build the bitmap yourself. I used the
built in OS X facilities for this, but you could probably do it
yourself by building the appropriate header and outputting the raw
pixel data yourself. Might try looking at the Wikipedia entry on the
BMP file format.
