iipmooviewer is very fine but I need to zoom in a little more (sometimes 20:1
pixel ratio (I know, this is huge but I need it)). But when I zoom in, I am
stuck at 1:1 ratio. Is there anyway to change this?
Thanks in advance!
You seem to have CSS turned off.
Please don't fill out this field.
There's no way to do this in the current iipmooviewer. I may add the ability
to go to 2x in the next release, but 20x will just give you massive
An alternative way to do this would be to scale up your TIFF image first to
20x the original size and use iipmooviewer to view that. This would also give
you better quality upscaling than would be possible by doing this in the
I know about the pixelization but it's a feature I would like for some reason
(low contraste detail that you can't see easily). I can't scale the tif image
to x20 because they are already massive (70kx70k pixels).
The workaroud I have found is to use the Firefox zoom feature but it restart
the viewer and mess it up.
Thank you anyway for your program. If you add the 2x zoom, I guess I could do
something to make it x20.
I tried to zoomify my original picture. The resulting TIF is 13GB big and the
server can't work with it. Here is the log:

Big.tif is about 200k x 20k pixels. And it'a tiny one :)
The TIFF standard doesn't allow for TIFF files greater than 4GB. But, the
latest libtiff beta supports BigTIFF which does. Are you using libtiff 4? I
haven't yet had a chance to test on super-massive TIFF images myself, but in
theory, iipsrv should work as normal if you compile with this.
Well, I didn't heard about this bigtiff library. As soon I have time, I will
try to find it and compile iipsrv with it.
Thank you :)
Hey this is this kind of size I need :
1095630 x 939495 ; 2875.94GB (well, size lower as possible of course)
The bigtiff stuff is now merged into the main libtiff library. The version 4
betas available should work fine.
Zooming 2X would be a feature I would appreciate as well.
