Re-saving images

Post by Brian Pugh »

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.
