I would like to be able to save a Bitmap to a graphic file, such as a JPG,
BMP, etc. Are there any 3rd party sources that provide a means to put this
functionality into my VS C++ 2008 application in /CLI mamaged mode? I'd
prefer not to write the conversions.
Also, is there a place I can find the BMP and JPG file format standards?

There's lots of 3rd party libraries available.
Built in to Windows, there's GDI+. http://msdn2.microsoft.com/en-us/library/ms533798.aspx
The .NET System.Drawing namespace has classes which wrap the GDI+ classes. http://msdn2.microsoft.com/en-us/lib...m.drawing.aspx

For JPEG, Google "JPEG file format" and/or "JPEG JFIF"
A typical (packed) BMP file is a BITMAPFILEHEADER struct followed by a
BITMAPINFO struct followed by the color table (if appropriate) followed by
the pixel data. http://msdn2.microsoft.com/en-us/library/ms532311.aspx

Thanx Mark!
I also discovered that Wikipedia also details image file formats! Pretty
cool! :)

If you're willing to call out to unmanaged code, here are two ways.
