Volunteers needed to run a select-polygon test - gasMask - 11-19-2024
Windows 10
Gimp 3.0.0 RC1
Hi,
I'm looking for volunteer(s) to run this test plug-in. The plug-in creates an image and selects a square polygon at the topleft of the image.
At least that what's it's supposed to do. However, the plug-in will crash while failing to select the polygon. The failure appears to be in the procedure: 'gimp-image-select-polygon'.
Code:
procedure = Gimp.get_pdb().lookup_procedure(
'gimp-image-select-polygon'
)
config = procedure.create_config()
config.set_property('image', image)
config.set_property('operation', Gimp.ChannelOps.REPLACE)
# Define a square of four points
# positioned at the topleft of the image.
config.set_property(
'segs', (0., 0., 250., 0., 250., 250., 250., 0.)
)
procedure.run(config)I'm willing to report the bug to Gimp.org, but I believe it's a good idea to have some proof before doing so. There's also the possibility that I'm doing something wrong, and someone could point that out.
To install the plug-in copy the folder into a Gimp 3 plug-in folder. After Gimp is restarted, the plug-in will appear on the Gimp window menu under "Development".
Thanks for your attention.

You can simplify that command like so:
images.select_polygon (Gimp.ChannelOps.REPLACE, (0, 0, 250, 0, 250, 250))
That worked for me when I ran it on its own, if that helps.

@gasMask
Just tested ... does not work for me.
Produces a new image, but no selection.
This is the error message I get in the termínal window:
Code:
Traceback (most recent call last):
File "~/.var/app/org.gimp.GIMP/config/GIMP/3.0/plug-ins/SelectPolygonTest/SelectPolygonTest.py", line 91, in run
config.set_property(
TypeError: could not convert (0.0, 0.0, 250.0, 0.0, 250.0, 250.0, 250.0, 0.0) to type 'GimpDoubleArray' when setting property 'GimpProcedureConfig-gimp-image-select-polygon.segs'(of course the plugins are not in .var but in .config :-( )
Nevertheless: I usually would do it the way CMYK Student suggested.

Just tested.
For me it worked.
I got the following messages in the terminal. Looked like an error but in the Gimp-window was a new image and selected.

It's not a selection ... only an active new image.
RE: Volunteers needed to run a select-polygon test - gasMask - 11-19-2024
I screwed up the test. the polygon points were misconfigured. This is a revised version, but the error persists for me. The image has no selection.
MrsP-from-C, thank you for your help. I could still use a verification with this test. Any feedback could make Gimp development team's job easier.
Code:
procedure = Gimp.get_pdb().lookup_procedure(
'gimp-image-select-polygon'
)
config = procedure.create_config()
config.set_property('image', image)
config.set_property('operation', Gimp.ChannelOps.REPLACE)
# Define a square of four points
# positioned at the topleft of the image.
# (x, y, ...)
config.set_property(
'segs', (
0., 0.,
250., 0.,
250., 250.,
0., 250.
)
)
procedure.run(config)The 'image.select_polygon' function works for me too.
With gimp-image-select-polygon', I believe the problem lies with 'GimpDoubleArray' which could have a wider impact.

RE: Volunteers needed to run a select-polygon test - MrsP-from-C - 11-19-2024
Still no selection created.
I thought it could be because of the point values 0.0 and so.
But changing to integers didn't help either.
So I wonder what is supposed to fit in there?
It wants a 'GimpDoubleArray' whatever that is ... No idea of how to create that.

Thank you MrsP-from-C for your help. I've posted an issue.
