  Managing tool options and window positions
Posted by: Ofnuts - 04-23-2021, 08:28 AM - Forum: Tutorials and tips - Replies (2)

There are two ways to manage tool options in Gimp:

  1. Always start with the same settings. This is best if you work on various projects, and also if you are a beginner, because you can then reset the options by restarting Gimp
  2. Saving your settings between Gimp sessions. This can be useful if you work on a few big projects
The choice of behavior is directed by the options in Edit ➤ Preferences ➤ Tool options ➤ General ➤ Save tool options on exit. You want this unchecked for option #1, checked for option #2:

   

If you use option #1, you have to make sure once for all that your default options are to your liking by either:
  • Click the Reset Saved Tool options to default values  button:
   

Or:
  • Make sure that the following are as you want them:
    • All options in all tools (for instance font and font size in the Text tool, or the "corrective" flag in transforms)
    • The current brush, gradient, pattern, and the foreground and background colors
    • The active tool
  • Click the Save Tool Options Now button:
   

Your options are similar for window positions, but this is usually less critical. Saving window positions is often a good idea, but be careful if you use several monitors, a saved window position can end up on a screen that is no longer here. Settings are in Edit ➤ Preferences ➤ Interface ➤ Window management ➤ Window positions:

   

A last place to check with a similar choice is Edit ➤ Preferences ➤ Input devices for input options mostly related to painting:

  VDF in GIMP
Posted by: Winston - 04-23-2021, 12:46 AM - Forum: General questions - Replies (10)

Is it possible to use VDF plugin video effects as picture effects in GIMP, and if not, could you add the feature? Could I convert a VDF to PY somehow? Could I download a plugin and open as an effect, and type the path and open VDF in GIMP?

Yes, I know, videos are in motion. At least applying as 1 frame might work... Right?

  Remove plain background, set it transparent
Posted by: bobJ - 04-22-2021, 10:07 PM - Forum: Scripting questions - Replies (4)

Hello,

I have 1500 png to process so I'm searching a script/plugin to do this.

Given a png, I would like the script to do the following:
- do a magic selection (wand/fuzzy) with starting point coordinattes 1,1 (I know this pixel is the background color)
- remove this selection and have transparency instead

I tried this script in a plugin via BIMP:

Code:
def plugin_use_fuzzy(timg, tdrawable):
   
    pdb.gimp_layer_add_alpha(timg)
    pdb.gimp_image_select_contiguous_color(timg, 0, tdrawable, 1, 1)
    sel = pdb.gimp_image_get_selection(timg)
    pdb.gimp_edit_cut(sel)
But it does nothing.
Could you help me please?

  GIMP V2.99.4 Flatpak Python Issue
Posted by: programmer_ceds - 04-22-2021, 04:49 PM - Forum: Extending the GIMP - Replies (11)

I have installed V2.99.4 flatpak and can run this or V2.10.24 as I wish but not quite in the way suggested where you have to use a flatpak command to select the version that is to be run (beta or stable). If I use the command to select the beta version the Menu/Graphics/GNU Image Manipulation Entry always starts V2.10.24. To start V2.99.4 I have a bash script. I'm not sure that this is relevant to the issue noted below.

When I start V2.99.4 in a terminal window I see the following error message:

Gtk-Message: 17:32:23.772: Failed to load module "xapp-gtk3-module"

So far as I can tell I have this module installed (file usr/lib/x86_64-linux-gnu/gtk-3.0/modules/libxapp-gtk3-module.so exists)

I have also taken the text for the Python Goat exercise and renamed all occurrences of 'goat' to 'goatee' and placed the file in a subfolder of the user plug-ins folder but it doesn't appear in the GIMP menus. Initially I made the mistake of placing it directly in the plug-ins folder and received a warning from GIMP - so it is looking in the user plug-ins folder.

The latest version of the python goat exercise script, as downloaded from the gitlab site, contains statements that it relies on Gimp 3.0 and GimpUi 3.0 - I have tried changing these to 2.99 since that is the beta version - this had no effect.

Has anybody else had more success in this respect?

I thought I would go through the scripts that I have written and those that I have downloaded from elsewhere and update them for GIMP 3 if I could (starting off by running them in V2.10.24 with the --pdb-compat-mode=warn option to report deprecated scripts). I have successfully updated all the .scm files - some run without a problem but many fail with the (known) error message about GimpObjectArray being an unknown return type - I think I just have to retest these when V2.99.6 becomes available. However, as noted above I have hit a problem with the .py files.

  half of the tools don't work
Posted by: bombitmd - 04-22-2021, 03:52 AM - Forum: General questions - Replies (6)

I can't find any solution on the Internet.  Everything used to work a few weeks ago, now half of the tools won't work.  

Works:  
- move
- select tools
- crop
- scale tools
- paint bucket tools
- text tool
- colors

WON'T WORK:
- pencil, paintbrush, etc
- eraser
- clone
- smudge

I've followed all the recommendations I could find.  It's in RGB mode.

I'm stumped

  toolbox (mostly) hidden behind 'tool options'
Posted by: ottenm - 04-22-2021, 12:17 AM - Forum: General questions - Replies (4)

Periodically, I open GIMP and it looks like the toolbox is missing. But on closer look, a little sliver of it is sticking up above ... is it 'tool options'? The top row is actually usable if I can remember which icon is which.

I know I can get it back following Edit > Preferences > Interface> Window Management > Reset Saved Window Positions to Default Values, and then exiting and restarting GIMP (and moving and resizing the window back), but every couple of days it's becoming tedious/frustrating.

Any ideas?

  Shrinking a selection to ~1px width
Posted by: PSNick - 04-21-2021, 11:14 PM - Forum: General questions - Replies (5)

Is it possible to shrink a selection to, for example, 1px width without the selection disappearing in the thinner areas?

Let me give you an example. In the image below, I have selected the "walls" at the edges of this map, shrunk that selection slightly and converted it to a path (in green). The problem is that when I convert it to a path, what I'd like is to instead have a single line through the middle of those walls, instead of two bordering the selection. But if I shrink it too much, some parts of the selection will completely disappear and I think that even if I managed that, the selection to path tool would create two lines anyway bordering the selection.

Perhaps a better question would be, can I create a path from a selection by filling in that selection instead of using the borders for the path?


Thank you!

Hello fellow Gimp users

I'm wondering if anyone can help me by recommending a drawing tablet for Gimp?  I'm using Windows 10 and the latest version of Gimp.  Does anyone use the Kamvas 13?  I've seen mixed reviews online with some saying it doesn't work with Gimp.

Thank you for any recommendations  Heart

  Notes of Pain plugin for Gimp?
Posted by: Amelia_Albergee - 04-21-2021, 04:36 PM - Forum: Extending the GIMP - Replies (3)

I was wondering if there was a plugin for Gimp similar to the Notes of Paint plugin for Photoshop by denis154. Or something on that end? Anyone know?
