Description Eumel 2015-05-14 14:12:36 UTC

On opening a pnm graphic, Gwenview (vivid, version 4:14.12.3-0ubuntu1) displays the following error message:

Loading ‘foo.pnm’ failed
Gwenview cannot display documents of type image/x-portable-anymap.

Also, during scanning, when the file is named foo.pnm.part, gwenview displays the image (partially, with the bottom black, according to scanning progress)

Reproducible: Always

Steps to Reproduce:
1. Have PNM file.
2. Open it with gwenview
3.

Actual Results:  
Error Message:

Loading ‘foo.pnm’ failed
Gwenview cannot display documents of type image/x-portable-anymap.


Expected Results:  
Gwenview displays PNM

I did further research and found out that  /usr/share/kservices5/qimageioplugins/pnm.desktop
was missing in my install for some reason unknown to me.
I then copied it from /usr/share/kde4/services/qimageioplugins/pnm.desktop
and now it works. Note that pgm and pbm files were present.

Seems to be some kind of packaging problem: Either the file is missing in the package, or it is not generated on install.

Same on Kde Neon - User Edition

Open *.pnm file say can not opened. remove extension « .pnm », gwenview open file correctly.

(I'll attach a test file)

Due to file huge size, more than 4000k allowed here... uploaded on launchpad: https://bugs.launchpad.net/gwenview/+bug/1460417/+attachment/4770251/+files/abc-gray.pnm

Comment 4 Christoph Feck 2016-11-02 18:08:38 UTC

Rename the file to *.ppm, *.pgm, or *.pbm, depending on the actual image type.

Comment 5 Alex10336 2016-11-02 18:11:51 UTC

It's .pnm file. generated by « scanimage ».
