[digiKam-users] Using pdf files for images

[Gilles Caulier]

Hi,

You can add PDF as type mime in DK setup, but the last time that i do
it, I see few time latency introduced to render thumbnail and preview.

Typically, there is no specific implementation to render PDF in
digiKam. We delegate the job to 2 possible codec :

1/ ImageMagick
2/ QImage

Depending of the structure of PDF, ImageMagick will take a while and
provide a wrong preview. Here i used my large lesson class
documentations generated with LibreOffice, and the result was really
really bad.

I don't yet tested with QImage codec.

This is why PDF is not included in type -mime by default in digiKam.

So we can tune a little bit in DK to the right codec to see which one
is the best. We need PDF samples from your collection to see the
result.

We have 2 bugs about this topic in bugzilla. PDF is a long story, and
bug have been finally closed because no real and simple solution can
be found :

https://bugs.kde.org/show_bug.cgi?id=145295
https://bugs.kde.org/show_bug.cgi?id=226023

So feel free to comment and reopen rigth file in bugzilla to continue
this discussion.

Best

PS : excel and word as photo container will not work at all, i'm
sure... It's definitvely a bad idea.

Can I add this mime type to the configuration without creating problem with digikam processes?. Can I also add mime type for excel and word files as we receive these files with photo embedded.
