Joris, Alex, Leonhard,

thanks for discussing this topic so deeply, I appreciate that.

Somehow I'm lost. Can I now use TIFFClientOpen to pass a memory blob
to libtiff, and use TIFFRGBA to get it decoded or do I have to use
ImageMagick (thanks, Leonhard!)

The only problem with passing a blob of memory to libtiff using TIFFOpen I saw
was that libtiff uses internally a "tif" handle
to an internal data structure, and without doing I/O first I would not
have the internal structure filled correctly with all the information
libtiff expects. And while researching that problem I could not believe that
an *imaging* library like libtiff expects you to do I/O first, before you do
the task the name imaging library stands for. 

I try to  avoid to use another wrapper like ImageMagick, when I only need a
powerful lib like libtiff is  for decoding various flavours of tiff images.

Thanks
wolfram
