My company is using Tiffs with geospatial data, so are dealing with the BigTiff format, plus several custom tags. The images are stored with (I think I'm using the terminology correctly here) pyramid structures/directories, so a massive image can be zoomed in/out.

They have a "shapefile" which defines multiple regions within the image, and we chop up the single large tif into thousands of smaller images and store those in a database for analysis.

Does libtiff support (allow? provide API for?) multi-threading? I would like to read in a single 50-GB file and assign different threads/processes to extract the images.
