Advanced JPEG export missing options and mismatch #233

Open adorbabble opened 4 years ago

adorbabble commented 4 years ago

BIMP’s “Change format and compression” operation for JPEG does not have the same advanced options as the “Export Image as JPEG” dialog in the latest versions of GIMP (2.10.18 at the time of writing this issue) : “Use quality settings from original image”, “Save Exif, XMP, etc. data” and “Use arithmetic coding” are missing ; the “Save baseline“ option has been removed from GIMP, I think ; “Use restart markers” is also missing from BIMP ; the options for Subsampling use different labels.

Here is a picture, with BIMP on the left and GIMP’s standard dialog box on the right :

jpeg_adv_options

(Sorry for the French in the left dialog box, I’m using GIMP in English but my Windows is in French, so I guess that BIMP uses French because of that and I haven’t found how to change it)

I guess that the code in BIMP has not been updated to match the export as jpeg options of GIMP ?

By the way, I wish I could contribute, but so far, I only know the very basics of making a GIMP plug-in with Python, and struggling to make it work beyond the simple “Hello world”

Thank you for this great tool !

I'm also looking into a possibly related issue. Trying to convert HEIC to JPG in batch, but the JPGs are not rotated for some reason? (when opening in GIMP, they're fine; in GIMP's preferenced I did check to export Exif data)

Update: for anyone having the same issue, it seems to help to upgrade from GIMP 2.10.28 to 2.10.32

Apologies for this comment! :)

It appears it use to work if you selected "keep original modification date" (#133) but this doesn't show the additional options and this workaround now fails too (#393)

I was using HEIC photos taken on a Samsung using GIMP 2.10.32 and Bimp 2.6 on Windows 10 and all EXIF data lost when saving as a JPEG irrespective of the "keep original modification date" checkbox. The EXIF data is saved when exporting from GIMP manually.
