GlacierHello,
I really need to find a program or API that will allow me to annotate or insert/ append a 2 to 3 inch blank space on tiff images that are 100,000 pixels in height. ............so far nothing handles these really large images...................
any ideas.........?

Without telling us about the "so far", you will get many results from the "so far".

HTH,
Michael

I/ve tried (actually my programmer has) InforMatik software (informatik.com)
and Pegasus software
.............they both have good image apps but can't handle the really large ones. over 100,000 pixels in
height..............................possibly engineering software would work?

Try ImageMagick: http://www.imagemagick.org You will still need a decent system to handle such images.

HTH, Michael

Michael,

Perhaps this sounds weird, but ImageMagick sucked at handling some *very large* Earth map images I threw at it. The GIMP was better.

I know, but the last time I mentioned that Imagemagick has problems, I was told that this is "hogwash" ;)

The GIMP seems to be one of the only apps that can handle large images, though. I remember someone who wanted to precess schematics of oil drill holes, and no other app seemed to handle them...

One of the things that should be kept in mind when working with very large images is that one should disable "layer and channel previews" in the preferences. Updating the previews can cause a major slowdown if the image doesn't fit into memory (or rather into the configured tile-cache).

I guess we could add some code that automatically disables previews for image (w/o undo steps) that don't fit int the tile-cache.
