Sorry : Software Centre.

the fastest way if it just for resizing, install imagemagick then run via terminal

convert example.png -resize 200x100 example.png

but if you wanna have a gui, I use gimp (probably a overkill depending on your use case)

Hey dbarron,

When I am looking in the Software Centre, it says it is allready on my computer. Perhaps it is a part of Gthumb.

Yes, it's usually considered as core for it's image manipulation.

+1 gthumb. I though Eye of GNOME did it but I am clearly mistaken.

Guys: THANKS.

I found out out how it works in Gthumb.

Greetings, Evert

It's been quite a long time that I can't resize images with Gthumb:

$ gthumb

** (gthumb:2207): CRITICAL **: 18:58:44.751: gth_overwrite_dialog_new: assertion 'G_IS_FILE (source)' failed

(gthumb:2207): GLib-GObject-WARNING **: 18:58:44.751: invalid (NULL) pointer instance

(gthumb:2207): GLib-GObject-CRITICAL **: 18:58:44.751: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed

(gthumb:2207): Gtk-CRITICAL **: 18:58:44.751: gtk_widget_show: assertion 'GTK_IS_WIDGET (widget)' failed

When i try to resize an image, gThumb gets stuck and I can't close it anymore. Please, take a look at this picture:

    crom5 Is this just when resizing one image or several?

      I have never tried to resize more than 1 image at once

      I've just tested and been able to reproduce this, will bring up with Josh as updating it to 3.8.0 locally fixed it.

      a month later

      Hello, it's working ok now.
      Thank you very much 🙂
