[Pkg-phototools-devel] Bug#945402: feh: Please add dcraw to the Suggests (or even Recommends) of the package

[Elena ``of Valhalla'']

Source: feh
Severity: normal

Dear Maintainer,

Up to buster, feh was able to open (a preview of) the raw files
generated by my camera (Canon EOS 1100D); after upgrading to bullseye it
fails with the following error::

    OJPEGDecodeRaw: Inconsistent number of MCU in codestream.
    feh WARNING: 20171230/141140-img_5195.cr2 - No Imlib2 loader for that file format

However, after a number of attempts, reading the manpage I noticed that
there is a better way to show raw files in feh, by using dcraw.

I think that having dcraw available in the Suggests of the package would
have helped me find this option much earlier, as that's the first thing
I checked, to see if I was missing some optional dependency.

I'm not sure if it's worth adding to the Recommends instead, as enabling
the use of dcraw is not automatic anyway (it requires the option
--conversion-timeout X with non-negative X, in case somebody finds this
report while having the same issue.)

Thanks for your work on feh
