Re: Thumbnail creation from shell possible?
Posted: 14 Sep 2016, 22:12
Here is a first draft
@Jan: If you don´t wish something like this, please delete!
CAUTION:
It may not be free from errors. Please work with backups only! USING at YOUR OWN RISK!!!
I put the code in a file in /usr/scripts with name mk_thumbnails and start with /usr/scripts/mk_thumbnails from within the start folder. The script works with 1 level subdirectories it ignors the "thumbs" folder and shouldn´t overwrite exisiting files. you can find the resolution within the script. I use S = 55x44, m = 201x134 and l=800x534. If you specify a watermark file, it adds a watermark, if watermark file exists.
For me it´s working fine with big folder. With the PhocaGallery build in function I need 1 to 4 seconds for each picture. Directly on my webserver this script create thumbnails for 10 pictures within a second.
Maybe someone has more ideas:
