Re-saving images

Hi,
I'd like to re-save a batch of images using the Optimise Huffmann Table and Rebuild Embedded Thumbnails
(just to save a bit of space), and can't figure out how to set up a batch sequence to do the job
Is this possible? Any ideas?
Brian

OK, looked at the options, and have now started to re-save
my images, with quite a good reduction in size
Thanks a lot,
Brian

Hello Brian,
today I had some time to look a little further into this.
Unfortunately phpBB is line-wrapping my table. Please copy & paste the following “code” from your browser to a text editor:
Code: Select all
output( jpeg 1-100 0/1 0/1 0/1/2 0/2/1 0-10 0/1 )
^ ^ ^ ^ ^ ^ ^ ^
File | Quality | Encoding | Optimize | DCT method | Sub-sampling factor | Smoothing | Rebuild
format | factor | 0 = Non-progressive | Huffman | 0 = Slow | 0 = 2x2,1x1,1x1 (4:1:1) | factor | embedded
| | 1 = Progressive | table | 1 = Fast | 1 = 2x1,1x1,1x1 (4:2:2) | | thumbnail
| | | | 2 = Float | 2 = 1x1,1x1,1x1 (4:4:4) | |
These settings can't be saved to an XBS script:
- Keep EXIF data
- Keep IPTC data
- Keep XMP
- Keep ICC profile
- Use estimated original quality if possible

Also remember that with Browser menu>Edit>Metadata>Clean... , you can optimize (though most other options here are for removing metadata, these don't need to be used at all)
and with
>Edit>Metadata>Recreate EXIF thumbnail , reconstructs existing thumbnail to match image
... all this without resaving.
