How to convert an image file to BMP programmatically using native Windows XP capabilities?

Is it possible to convert an image file to BMP format using WindowsXP's native libraries and scripting capabilities?

I'm talking about WSH, JScript, VBS, etc...
C++ is also good for what I need if it can be compiled with Dev-C++

Solution

Yes, you can. Look at the Image class which is part of GDI+.
