This is my proposal for a plugin dedicated to a much requested feature in GIMP 3.0: stroke paths with an arrowhead at the end.
It has one genuine feature, compared to other similar plugins (AFAIK): the body path is shortened to ensure that the arrow tip ends up reasonably well aligned with the path's last point.
This apparently trivial feature actually hid a rabbit hole. The requirement of cutting a Bezier curve at a specific point send me through a deep dive into Bezier curves theory and algorithms. :-)

The image below shows a selection of arrowheads styles available:

   

The documentation is here, and you can download the current version here.

Make sure you place the folder named "pl_stroke_arrows" in the GIMP plug-ins folder inside your profile.
Depending on your operating system, make the file "pl_stroke_arrows.py" inside this folder executable.
The plugin should appear at the bottom of the "Edit" menu.

The plugin has been tested, but some new bugs will probably happen. Please report here, preferably with a downloadable .xcf file to exemplify the case.

When ever I am attempting to do a PNG export on my M4 Mac mini with Sequoia, instead of popping up the PNG export options dialog, it just freezes. I can't interact with anything. On the toolbar will have a PNG-export listed, but no windows for it are available.

Hello fellow Gimp-Users.

I've been using Gimp for a couple years now.
As I got used to it, I also got used to the workflow and the shortcuts.
I just downloaded version 3 and to my surprise many shortcuts don't work at all (Ctrl+C/Ctrl+V/Ctrl+Zoom/Ctrl+H).
Also I was used to hit Ctrl+S to scale the current selection. Now it brings up the Shear tool and Ctrl+T seems to be for scaling.
I don't know what the developers were thinking on this release and why it would be a good idea to change shortcuts, people were used to for years. (vibe coding?)

However, in 2.8 everything works fine. My system is a clean W10 with more than enough performance.
Really dissapointed with this release. I know I can change my shortcuts manually, but why did they change them in first place? 
Anyone else facing the bugs of some not working at all?

Creating a paperback cover. Instructions from Amazon say:

Quote:Image color, size, and quality. Images should be in CMYK color to ensure your cover looks good in print. All images should be sized at 100%, flattened to one layer, and placed in your document at a minimum resolution of 300 DPI (dots per inch).
 
Flatten all transparencies. These can cause the file to print with missing or distorted content.

I was hoping for an update to this.  Have not experienced this before this latest upgrade.  You open the levels screen and it could take literally 5-minutes before it shows a histogram or your able to hit auto.  I have a gaming machine.  Maybe this has been mentioned 42 times already.

I am trying to call a gegl edge detect filter repeatedly in a while loop as here

I'm running GIMP 2.10.20 on Windows 10 on a 4K screen.

I searched for and found various GIMP mask tutorials but for some reason it never comes out right.  

I have a specific image that I'm trying to "enhance" with a mask.  BTW, this image is a copyright released image found here for any would-be copyright nazis out there.

I'm trying to get this image here.......




to look like this image here.........




As you can see the second image has a very light sort of sepia tint to it and I'm guessing they made a mask over the whole image.  So if I like the second image better then why don't I just use the second image?  I have a higher resolution image of this image than the one that I found online that's been masked and in addition to that the second image has been cropped and I want to use the uncropped image.  

Can someone give me detailed instruction on how to get the first image to look exactly like the second image by making a mask?  Thanks in advance

I have done this  thing for years so something must be wrong with my layers. I need to clean up the area in top left bit by bit.
I pasted a vertical piece at the top left of the image in the top layer. In this situation I usually clean up the excess with a brush in a mask on the side. I did as follows:
1. made a selection  from the image part of the layer. If I click once inside the selection it stays, If I click twice it disappears.
2. move to the mask
3.switch from selection to brush tool
4. selection in image disappears 
I am doing all this because I can't run the brush in a straight line.
The selection is large compared to the tiny area I need to remove, but I think that I am in the right layer.
I also tried a New from visible on top, selecting always from the image part of the layer of course, add mask, but selection disappears as I add the mask. Thank you.

Version 3.0.4 is running on one computer. Just installed the same version on another computer. The new install shows a big blank window. Is it possible to copy a file from the first computer to the second to avoid manually setting display preferences? Both systems run Windows 10.

Hi, I just set out to write a tinyscheme script that retrieves the list of files from a folder using file-glob and although it looks trivial I can't get it to work. 

the line in question is:

(let* (filepaths (cadr (file-glob (string-append input-path "*.png") 0))))

which always returns empty whether I place it in a script or type a version into the console. Gimp just tells me that parameter 1 to cdr needs to be a pair.
Yes, I have verified that the folder pointed to by input-path exists and that there is at least one png file in it.Permissions are ok (I can load the file explicitly)
I have tried unix style and windows style path separator: nothing works.

I can hardly believe something this fundamental is actually broken - is there something about my setup that is wrong? I have a standard 3.04 installation using the windows installer any insights are appreciated.
