Re: How to read *.bmp *.wav files?

The code for reading *.wav files is available in the
Miscellaneous`Audio` package, which comes standard with Mathematica
(the documentation for it is in the _Guide to Standard Packages_).  I'm
not immediately aware of any code to read bitmaps, but the format is
well-documented (almost any Windows programming book that covers
graphics will have it) and not too difficult to parse.  However, I will
mention that binary reading under Mathematica for Windows is
problematic--it's very slow and it sometimes does text-binary
translation which is very bad.  If you decide to code this routine
yourself, I recommend reading in the bitmap file with FastBinaryFiles
(0206-783 on MathSource).
