Hi!
It should be possible to thumbnail a PNG completely
from the image
stream, using minimal memory (at the expense of speed).
progressive/interlaced images, anybody? still, someone has to contain
few lines of pixels.. we've looked at this problem too many times,
and still - images have internally to be expanded to full
uncompressed bitmap.
Imagemagick is a tool that is a jack of all trades and
best solution
for none. If the problem is with using Imagemagick to do it, use
something else.
use what? current GD maintainer was in our channel few times, telling
about future product, that might save us. that future product doesn't
seem to have appeared.
if anyone wants to revisit GD support for thumbnails, performance et
al - please tell your results.
really, this whole discussion is about 'oh, look, these guys have no
clue', when we had certain investment of time looking at what can be
done.
BR,
