Hello,

My wife and I enjoy creating stained glass projects.

Is there a way of opening an image in GIMP and then convert it to outlines of the image?

Typically in stained glass patterns there is a 3mm line that represents the thickness of the soldered areas connecting the various glass pieces together.

say for instance, that I opened an image of a birdhouse in GIMP. 

would it be possible to have that image converted so that there are outlines of all objects within that image?


thank you all

I am using GIMP 2.10.12 running on Windows 10 and also windows 7

Could you attach the birdhouse image?

You could try this one DIEGO_MOSAIC_Mosaic_Stained_Glass_QT210.py the original posts are from http://gimpchat.com/viewtopic.php?f=9&t=17380#p238787 Any questions about it should go there.

Because that is 7zipped and also requires a specific pattern, DopeCrystals04seamless.jpg, the two files attached as a regular zip.

It also requires the gmic_gimp_qt plugin from http://www.gmic.eu  The windows version has an installer, that is the one to get currently: https://www.fosshub.com/GMIC.html?dwl=gm..._win64.exe

What you need to do: 
Install gmic_gimp_qt 
Unpack the zip: Put the file DIEGO_MOSAIC_Mosaic_Stained_Glass_QT210.py in C:\Users\"yourname"\AppData\Roaming\GIMP\2.10\plug-ins
Put the file DopeCrystals04seamless.jpg in C:\Users\"yourname"\AppData\Roaming\GIMP\2.10\patterns

In use, it looks like this: https://i.imgur.com/LGVuMxv.jpg
There is also a stained glass filter in the gmic plugin. Not so good. Over complicated unless the image is very simple.
