    Thanks Robert for letting me help.

    This project allows you to convert wsq file fingerprint to bmp and tif format and bmp,tif to wsq format. This project is in .NET.

    I tested the code. The wsq to bmp works fine.
    However Bmp to wsq gives a different result to the Nbis (c++) equivalent.
    Not sure why , it looks like the compression is greater resulting in a poorer quality wsq file.
    The wsq file is slightly smaller, so when converting back to BMP , the image is of a lesser quality than the Nbis equivalent, and the ridges become increasingly jaggered.

    Anybody else experience this?
    Perhaps I missed something?
