Hi folks!

It's been a really long time since I've posted to a forum, so please forgive me if I don't have the normal "forum manners". I'm looking for help with a very specific problem that I don't have the know-how to solve.

I have an active stylus with pressure sensitivity that I'm using with my HP Spectre 360. It's a touchscreen computer and the pressure sensitivity does seem to work well with OneNote for Windows, which is not an application I'd like to use for drawing. I knew that there weren't any pressure sensitivity settings in Paint.Net (the program I've been using for a while for digital art) and decided to download GIMP after reading good things. 

However, now that I have GIMP, I can't seem to find a way for it to register the pen as different than the mouse, or to sense that there is different pressure being put on the pen nib in general. It's very sad and a little tiring to have it work in an application not made for drawing, then not work at all in an application made for art, as someone who enjoys non-digital drawing.

If there's anyone out there with any solutions to this problem- be it an external driver or fiddling with settings or anything, I would really appreciate the help!

Thank you so much in advance!

Hello everyone,

it might be me overlooking something obvious, but I cannot find anywhere the procedure to call the high-pass filter in Python-fu.

Just to be on the same page, the filter can be found in "filters - enhance - high pass.." in GIMP 2.10.

I cannot find it in the procedure database. I also tried to look in the scripts folder, in order to import it or re-implement it, but it's not there, so it might be a built-in.

Do you know how I can call the high-pass filter in a script?

    Is there a way to fix this? Example: When using the brush on a non transparent layer, everything is fine and the transition is smooth. But when I draw on a transparent layer the transition isn't as smooth anymore and looks quite bad. I just hope there's a way to get rid of this.

With this plugin it is possible to place guides on specific places :

https://www.gimp-werkstatt.de/forum/view...f=24&t=772

After installation one can find the plugin in the menu : Image / Guides / Mehrere Hilfslinien setzen  

Tested on Gimp 2.10.18 / windows 10

As someone eventually raised an issue about scripting GEGL: https://gitlab.gnome.org/GNOME/gimp/-/issues/1686 I took the code Massimo wrote and butchered it a bit to make it easier to create multiple PDB entries.

I would appreciate it if someone on Linux would try out my code to see if it works (as I only have Windows).

Suggestions on code improvements/re-writes welcome


There are two files in the zip archive. The Python that does the work and the .scm that uses the new gegl operations, which registers scripts here
   

Thanks

EDIT 2020.08.24: Removed attachment as it's the wrong way to do it.

I selected an area of a png black-and-white drawing, then pasted a separate file into it and anchored it, then moved on to other parts of the image. Then I decided I wanted to scale the former pasted image bigger and unfortunately I had already saved it to send to someone, so the Edit menu was wiped out. So I ran the rectangle select over the entire pasted area (and beyond the borders as well), knowing that the existing parts of the drawing would not be wiped out and so was able to erase the pasted area. But when I re-selected the area to re-paste the file, the entire selection I had just made returned (beyond the borders as well) and so the file pastes in those parts outside the area that I want to paste into.

Is there a way to undo this selection and start fresh?

I am seeking help setting up an automation BIMP procedure to process simple gray scale files in the following way... Hopefully the illustration will help explain.


The GIMP process I need is the following simple process...

1. Open gray scale image
   
2. Select by color
   
3. Stroke selection
   
4. Save file

I'm using gimp to apply freckle textures to a face texture for a video game. All textures are other peoples' work; I'm just pasting the freckles as a new layer onto the face and colorizing them. This is my first exposure to GIMP. I noticed that the face freckle texture is lighter than the neck freckle texture. As a result, when colorized to the same HTML value and applied to the character model, the neck freckles are much darker than the rest (example). Since the original freckle textures as greyscale, is there a way to normalize the max pixel intensity of the neck freckle texture to that of the face, so that they come out to a balanced intensity?
