Would you mind explaining what you exactly mean as ROI? The abbreviation stands for Region of Interest. This is clear, but what definition of ROI you refer to? I have a feeling there is potential for another confusion here.
Hmm...well I mean simply that, a region of interest....in many contexts in the current discussions it is almost synonymous with a subimage_view...
OK, this is clear now. I have met term ROI mostly used to describe a certain coding strategy where regions which are encoded to higher quality (and stored as such in a format) than the rest of image. This is common technique used in JPEG2000 or PGF. This also allows faster decoding and access to those subimages where each of them is ROI.
Please feel free to correct me if you think I'm using the term in wrong/confusing ways...
I just wanted to confirm that we think of the same writing and reading the term ROI.
ps. have you by some chance ran the GDAL test(s)?
