Using nconvert v7.70 to re-compress 16b tiff file results in a stuck process. Calling as following:

nconvert -org_depth -c 3 -overwrite myfile.tif

GraphicsMagic and its `identify` command:

Thank you very much for your efforts and quick response! It's working now.

Any idea when there will be an update for the linux version?

I've encountered a different problem when extracting stacked tiff files with nconvert version 7.80. When I run:

Code: Select all

nconvert.exe -org_depth -out tiff -xall ./DJI_0012.TIFF

The extraction process stops exactly after 3258 files even when there are a lot more images left. Tiff-stacks with less images work totally fine but as soon as there are more than 3258 stacked images, nconvert stops at exact the same position every time no matter how many images are left to extract.

Perhaps it's just misuse or wrong/missing parameters but from my perspective it could be a bug, as well. I'd appreciate it very much if someone could look into that. Thanks!

Thank you, the conversion is working.

But I can verify, that the conversion stops after 3258 pictures.
