1998.12.08 21:19 "TIFFReadRGBAImage()", by Frank Warmerdam


I imagine this has come up many times before, but I just recently joined the list after a few years off it, so I don't know the answer.

Is there a reason that the TIFFReadRGBAImage() and related functions only allows you to do the whole image in one pass? What I would like, is an API that allowed me to read a single tile or strip into an RGBA buffer with all the other processing currently found in the TIFFReadRGBAImage() API.

I have briefly reviewed the tif_getimage.c code, and doing the above does not seem trivial. Would there be significant interest in such a capability if I took the time to implement it?

I have two clients that I think would benefit from this, so I could afford to spend a couple of days on the job. If it's much more I will likely have to eat the time myself.

Until recently I hadn't realized how much of the photometric interpretation and orientation stuff I have been ignoring.
