Error while executing script-fu-paste-as-brush:

Could someone help me? Thanks so much.

Warm Regards

  Filling with sharp edge
Posted by: szbalogh - 05-17-2020, 08:47 AM - Forum: General questions - Replies (2)

I want to extract some figures from a photo and edit it. Want to fill the selection but it adds a thick border to it.
Soft edges are reduced to 0 pixels. If i add some 50 pixels it extends the border. 
How can i fill the selection only up to the selection line?
I am new to GIMP, please help, it is so annoying that i cant proceed.

  ofn-text-path-selection
Posted by: Ofnuts - 05-14-2020, 10:14 PM - Forum: Extending the GIMP - Replies (4)

If you create text where there is an overlap between characters:

   

The strokes of these characters overlap:

   

And if you try to get a selection from that path you don’t get the initial text:

   

This is because Gimp uses an “even-odd” algorithm to determine if a pixel is selected or not: drawing a line from the pixel in any random direction, the pixel is outside the selection if the line intersects an even number of strokes (0
is considered even), and inside the selection if the line intersects an odd number of strokes. If the overlap areas, such a line intersects two strokes, one for each character, so the overlap area is unselected.

This plugin uses a different algorithm: it identifies the strokes that belong to the same characters (more accurately, sets of nested strokes), and adds theses characters separately to the selection, so the overlap areas are the union of the selections for each characters and are selected:

   

As usual plugin is here. Enjoy.

Thanks to Akovia for the incentive and the help. Your PC shall not have burned in vain!

  New Install Problem w/Cursor
Posted by: Dawter - 05-14-2020, 02:56 PM - Forum: General questions - Replies (1)

I've been using an old Gimp for ages and just upgraded to 2.10.18.

My cursor will close out things but will not allow me to click on for example, When I'm in Preferences and I chose which theme I want it lets me do that. But when I click on "OK" to save it, it does nothing. It lets me X out and close things but won't allow me to save my preferences.
Any idea as to why? Thank you.

Photo Automated merging and export
Posted by: Bayard - 05-14-2020, 09:00 AM - Forum: Scripting questions - Replies (3)

Hello everybody !

I'm glad to find an active forum about this marvelous tool^^

So... ! I'm here about a very boring project, and I thought I can find some experts to give me one or two advices...  Shy

Here is the things I need to do :

- import a png file into a .xcf
- put this new layer between two other layers (for eg. Color2 and Color3, and I want my new png file to be slipped between them !)
- export the whole thing as a new png !

And I have to do this for some hundreds files  Confused

Do you know if it exists scripts I can use to make a batch, instead of doing it manually ?

Thanks a lot, have a nice day !

  Clone Multiple Patterns At Once?
Posted by: Drain - 05-13-2020, 08:17 PM - Forum: General questions - No Replies

I'm looking for a way to simulate the "multiple patterns at once" effect going on in the video below. I already have large tiled patterns for the cross hatched rock and the stone floor and they work great using the Clone Tool. 

The other thing I can't figure out (and GIMP might not have this ability) is how to setup a brush to create the squared off walls that's open on the trailing edge like in the video.





Thanks in advance for any help Smile
