This is an implementation of the WSQ algorithm as described
in "IAFIS Use of the Wavelet Scalar Quantization (WSQ) Compression/
Decompression Algorithm," J. J. Werner, 8 December 1992. The implementation
is designed for well-equipped IBM-type desktop computers using
the Windows 3.1 operating system. It reads .BMP files and writes
compressed files, and vice versa. Results are displayable on a
high-resolution video monitor. The quality factor can be set under
menu control. Computations are performed in integer arithmetic
-- no floating-point coprocessor is needed.
