Hi Olivier,
Last, but not least, there is no support for tiled TIFF. Nothing about tiled TIFF is defined in tiff_tags.hpp. Maybe we could add in tiff_device_base a read_tile method, similar to read_scaline (sic), but which simply swap TIFFReadScanline with TIFFReadTile.
So, do you plan to add this stuffs in the new version of GIL io? Maybe I could help. Let me know.
You are correct there is no support for tiled TIFF, yet. I think I was silently hoping that TIFFReadScanline would work, even though it might be inefficient. If you have some time at hand I would be very thankful if you could add support for tiled TIFFs. Of course, I can help you out with any questions or problems you might run into. I have fixed the spelling error ( read_scaline ). ;-) Thanks, Christian
