Hi All, I am trying to develop a simple Tiff library with using VB.NET. (if
you know any, please inform me)I've read the Tiff 6.0 specs., and achieve to
read the tags and the image data. I can see that image is LZW compress. I've
find an LZW library to decompress the image data. After decompressing the
data, I wrote it to a file but the output is not an valid image file.
(I want to extract pages as bmps from multipage tifs) The Tiff info (Aware
Systems AsTiffTagViewer)SubFileType (1 Long): ZeroImageWidth (1 Short):
50ImageLength (1 Short): 50BitsPerSample (3 Short): 8, 8, 8Compression (1
