GIMP won't list .jpg files but will edit renamed .jp2 file

udvAQZJY · **Joined:** Jan 21, 2018 **Posts:** 4

I have a curious problem. I installed GIMP 2.8.18 using a fresh profile on Linux.
The file-jpeg plugin is installed however GIMP doesn't list .jpg or .JPG files in a directory. I have to rename the file to .jp2 for GIMP to be able to list it and thereby read it. I was wondering if anyone had any suggestions why this is?

Seond question, what is the gtk toolkit component for getting an image preview in the open file dialog box?

I know these features exist from an earlier experience with GIMP. I changed my system and am having to rebuild from first principals.

Edit the "pluginrc" file in your Gimp profile, the section for the plugin that loads jpegs it should look like this:

Code: Select all

(plug-in-def "/usr/lib/gimp/2.0/plug-ins/file-jpeg" 1494589442
    (proc-def "file-jpeg-load" 1
         "loads files in the JPEG file format"
         "loads files in the JPEG file format"
         "Spencer Kimball, Peter Mattis & others"
         "Spencer Kimball & Peter Mattis"
         "1995-2007"
         "JPEG image"
         0
        (icon stock-id -1 "")
        (load-proc
            (extension "jpg,jpeg,jpe")
            (magic "6,string,JFIF,6,string,Exif")
            (mime-type "image/jpeg")
            (thumb-loader "file-jpeg-load-thumb"))
         ""
         3 1
        (proc-arg 0 "run-mode" "The run mode { RUN-INTERACTIVE (0), RUN-NONINTERACTIVE (1) }")
        (proc-arg 4 "filename" "The name of the file to load")
        (proc-arg 4 "raw-filename" "The name of the file to load")
        (proc-arg 13 "image" "Output image"))
    (proc-def "file-jpeg-load-thumb" 1
         "Loads a thumbnail from a JPEG image"
         "Loads a thumbnail from a JPEG image (only if it exists)"
         "Mukund Sivaraman <[email protected]>, Sven Neumann <[email protected]>"
         "Mukund Sivaraman <[email protected]>, Sven Neumann <[email protected]>"
         "November 15, 2004"
         ""
         0
        (icon stock-id -1 "")
         ""
         2 3
        (proc-arg 4 "filename" "The name of the file to load")
        (proc-arg 0 "thumb-size" "Preferred thumbnail size")
        (proc-arg 13 "image" "Thumbnail image")
        (proc-arg 0 "image-width" "Width of full-sized image")
        (proc-arg 0 "image-height" "Height of full-sized image"))

Note the "load-proc/extension" item. What extensions are listed in yours?

Oh wow, great thanks for the swift response. Yes that now works. I wonder why .jpg isn't set as extension option by default?

Just to answer your second question - The one in your reply. I think .jpeg use to be the default extension but was changed to .png for a web friendlier file because it supports transparency and .jpeg doesn't. Actually it will export to what you use the most - gimp files can be exported in many formats and the native extension is xcf.

By default in my open file dialog the image type selector is "All images". Not in yours?

All Images is selected by default.

I just stumbled on yet another problem. When you "export" an image there again is no .jpeg option.

Just enter .jpg as the extension. Example - "blablabla.jpg"

If I do that I get this:

Code: Select all

The given filename does not have any known file extension. Please enter a known file extension or select a file format from the file format list.

Works perfectly here, no clue what your issue is. What are you running gimp on anyway?

FYI, I'm running gimp 2.8.16 on Linux x64.

It looks like your Jpeg plugin is broken, or has been overridden with a a JPEG2000-capable plugin (my stock Gimp 2.8.22 doesn't know about the JP2 extension).
