IN CASE you don't want to read the documentation :( here are a few things you
need to know about:


What is WaveTrIC?

        WaveTrIC stands for Wavelet Transform Image Coder.

        WaveTrIC is a still image compressor/decompressor as well as 
        a fast wlt files browser.

        This software compresses:
                * 1 bit monochrome images
                * 8 bit greyscale images
                * 4 bit VGA images
                * 4 bit RLE images
                * 8 bit RLE images
                * 8 bit color images
                * 24 bit true color images


How to install WaveTrIC?

        You need to copy the following files in the SAME directory:
                * wavetric.exe (executable program)
                * wltinv18.dll (decompression DLL)
                * wltfor05.dll (compression DLL)
                * msvideo.dll (display DLL)

        You also need to place the wavetric.ini file in your windows system
        directory.


How to compress bitmaps?

        1 - In the File menu, choose Open DIB File
                or you can click on any already open window holding a bitmap
        2 - In the File menu, choose Save As
        3 - Click on the Parameters button
        4 - Pick up the compression levels for luminance and chrominance 
                where minimum == minimum compression / best quality
                and   maximum == maximum compression / worst quality
        5 - If the input file is a an 8 bit greyscale file, check the "Input
               is greyscale" box
            If the input file is a 24 bit image, an 8 bit color image, or a
               VGA image, uncheck the "Input is greyscale" box
        6 - Pick up the entropy coder:	
                For now, you can only use the Huff + rle coder or no coder at
                all
	7 - Click on the OK button


How to read compressed files?

        1 - In the File menu, choose Open WLT File (default extension is *.wlt)
        2 - Pick up a file name	
        3 - Pick up a resolution ("Full" if you want to see the image full
	    size, "1/4th" if you want to see the image at a quarter
	    of its size,...)
        4 - Click on the OK button


How to find (.wlt ) compressed files on you hard drive?

        1 - In the File menu, choose Search
        2 - Give a directory name
        4 - Click on the OK button: this will generate a window with all the
	    lowest resolutions of the found files.


How to compress a BIIIIG bunch of files?

        1 - In the File menu, choose Run Script
        2 - Pick up a *.wls script file
        3 - Click on the OK button: this will execute the compression script
            file


How to create the script file?
The first line of the script must be [begin compression]
        On each following line put:
        1 - the input file name
               put a Tab or spaces
        2 - the ouput file name
               put a Tab or spaces
        3 - the compression level for luminance
            (from 0 (=minimum) to 84 (=maximum))
               put a Tab or spaces
        4 - the compression level for chrominance
            (from 0 (=minimum) to 28 (=maximum))
               put a Tab or spaces
        5 - the entropy coder (0=none 4=Huff+RLE)
               put a Tab or spaces
        6 - 0 if the input file is a color file, 1 if the input file is
            a greyscale file
               The last line of the script must be [end compression]


How to dither to 8 bits?

        1 - In the Edit menu, choose Dither to 8 bits (you can use two methods)


How to quickly get infos on an open wlt or dib file?

        Place the mouse cursor on the window holding the file and click the
