Thumbsup used to stop at the first problem processing a file.
This was a problem on large galleries where you’d need to run it again and again, fixing files as you went.
This change:
- skips problematic files and shows a summary at the end
- logs all warnings/errors to <thumbsup.log> when running the default output
Also refactor and cleanup of the logging logic.
GraphicsMagick can’t process animated GIFs well unless all frames are coalesced, which creates very large files.
This means there is a new dependency on Gifsicle which is very good at working with animated GIFs.
- Thumbnails are still processed through GraphicsMagick (more options, e.g. centre-crop)
- Large previews of animated GIFs go through Gifsicle
The startup checks are updated to check for the Gifsicle binary.
Fixes#96.
This will help understand usage patterns to know what to focus on, e.g.
- are many people using thumbsup on Windows?
- are there many galleries with > 10,000 photos?
