...konnte eine Datei mit dem MIME-Typ "image/jpeg" nicht konvertieren

[chrisbonn]

It is not possible (nextcloud 25) to convert JPG images in the folder, all utilities in my Debian 11 are installed, on other cloud instances I know it does not work either, it does not seem to be due to my configuration.

A maintenance:mimetype:update-js I still did, the package img2pdf is also installed and with unoconv all other conversions run (odt/docx)

Here the error message from the PDF_Document:

Error converting wasserschaden/10_oeffnung_badew

Hi there, sorry for not addressing this issue earlier. It could be a "version problem" with img2pdf. I.e. my app maybe assumes a newer version than in particular Debian has installed and uses some features which are not present in that old version. Could you please provide me with the output of img2pdf --version?

And perhaps try to run the following command-line on your server?

img2pdf - --rotation=ifvalid < JPG_INPUT > PDF_OUTPUT

If that "ifvalid" rotation option is not understood I have to leave it out for not up-to-date versions of img2pdf. The fix would be fairly easy to implement (either look at the version of just try another time without that option).

Hi - hello, I tested and the result is:

img2pdf: error: unrecognized arguments: --rotation=ifvalid

it is version: img2pdf 0.4.0 on Debian bullseye

and on the list of options I can't find a "--rotation=ifvalid", here:

[-h] [-v] [-V] [--gui] [-o out] [-C colorspace] [-D] [--engine engine] [--first-frame-only] [--pillow-limit-break] [--pdfa [PDFA]] [-S LxL] [-s LxL] [-b L[:L]] [-f FIT] [-a]

[--viewer-page-layout LAYOUT] [--viewer-fit-window] [--viewer-center-window] [--viewer-fullscreen]
[infile ...]

Your app in the Nextcloud is really a very good idea! Thanks for it!

Perhaps the commit a78735a might solve the problem. I have also uploaded a new pre-release to the Github and the NC app store. Perhaps you could give it a try.

The work-around is to check for the version and not add the "--rotation" switch if the installed version is too old. It would probably also be a good idea to augment the checks and notifications for missing helper apps to include supported versions.

Good morning, thanks for the quick fix for the img2pdf - this also works, great, but now the can't include the .odt documents. What am I doing wrong?

Hi there, can you please have a look if #28 is related and perhaps even provides a solution?
