Yes, you can query them over the "QueryFeatures" interface, so you can
see the names f.e. in PtGui's Info dialog.

YES!

That's very true, but also for the old one. So maybe 3-5 in total should
be enough. I kept them all, because for some special cases it is good
to have them, like Nearest Neighbor is good for Hotspot, but gives bad
results for picture, aabox is great for testing. My Top 5 would be:
spline36 - fast
sinc1024 - slower, makes sometime strange artefacts
aahamming - antialiasing, "fast", no sharpening
aamitchell - antialiasing, Slow, little sharpening
aalanczos3 - antialiasing, Slowest, some sharpening
So maybe it would be good to make an "beginner/expert" checkbox, to
hide the others (including the Gamma Field).
Any comments are welcome.

The Problem is PTSticher, because it seems, that the program allocates
the memory on its own, so the program crashes if you select a 32 bit
input image.
With Pano2QTVR (direct calls to the DLL) everything works fine without
modifications. (But Quicktime doesn't support 32bit, so you can only
extract the tiles...)

Thomas.
