Take a look at ImageMagick (<http://www.imagemagick.org>) which is an image processing library that uses libTIFF for it's TIFF support and fully supports working with in memory "blobs".
Correction: TIFF is one of the very few formats (the other is HDF) for which ImageMagick does not provide native BLOB support.
The reason for lack of support is because the libtiff API is not adequate. To be adequate, the API would need to support working with striped, or tiled data (using a accessor function we provide), and not require a file descriptor. Since TIFF is a very important format, we would really like to support TIFF BLOBs in ImageMagick.
