With Ofnuts plugin 'Decompose to color channels' I got quick a nice effect on a photo that was taken with a blue spotlicht in the back. Could be done with another workflow, but I found this a quick one.
I am trying to make a hi res from a image. Going to print I increase pixels but it does not seem to work. I am using version 2.10 Give me some detail and examples if you can.
Thanks
I have been trying to iridescent effect to this grey suit.
does anyone know if it can be dont with gimp and if so could you please aplly it to the following images.
and of course teach me oh wise ones!!
Hi guys,
So I'm on the road to develop a plug-in for GIMP 2.99.16, but I've just started out. I am taking baby steps and ran into this error at the get-go.
What I want to achieve:
I want the plug-in menu item to be enabled when there is no image opened.
What I changed:
procedure.set_image_types('*') <- Works.
to:
procedure.set_image_types('') # <- Broken.
What happens is that the menu item becomes enabled, but when I start the plug-in, I get an error:
"Procedure 'jb-plug-in-first-try' has been called with an invalid ID for argument 'image'. Most likely a plug-in is trying to work on an image that doesn't exist any longer."
procedure.set_menu_label("My first Python plug-in")
procedure.add_menu_path('<Image>/Filters/Tutorial/')
procedure.set_documentation(
"My first Python plug-in tryout",
"My first Python 3 plug-in for GIMP 3",
name
)
procedure.set_attribution("Your name", "Your name", "2024")
return procedure
def run(self, procedure, *arg):
Gimp.message("Hello world!")
# do what you want to do, then, in case of success, return:
return procedure.new_return_values(
Gimp.PDBStatusType.SUCCESS, GLib.Error()
)
Gimp.main(MyFirstPlugin.__gtype__, sys.argv)
On another matter, is there a way to refresh the plug-in, as in have GIMP reload it, so that I can edit code and not have to restart GIMP?
Hi pepes. I watched a video and managed to increase the fonts in Gimp which on my laptop are way too small.
I did this by altering the GTKRC file. Is there a place in that file to alter the icons too. I can hardly see my brushes and the main tools on the top left are too small as well. I used the icon theme reset to large. It is not large at all and hardly makes any difference. Please help as I would really love to use this software. but its just not pleasing to use.
Thanks JJ
Ok. Have struggled with installing Gmic for GIMP (v 2.10.22) on Mac. After several days and hours of research, I was able to install on Mojave. There is a lot on the web about install failing, so I kept on digging. The reason I still use 10.13 is due to several other CAD and 3D software that will not run on newer Mac OS (I know, but Engineered Software was bought by Form Z and it's taking a long time to release the updated version, also I have a dwg converter that won't run on newer OS). Any way, I used the Macports installation (download the correct version for your OS). Install Macports then open Terminal (utilities folder) and paste the command listed on their website to start the install. The install takes a while, you can monitor via terminal to see what is being installed (the terminal command to view what is going on is also on Macports website and it allows to see where everything is going, USE IT, especially by the end, where terminal tells you exactly the path to the gmic files, believe me, I learned the hard way). Ok, after about 1 hour or more, I think, everything will be installed BUT, and this is a big BUT, the packages are installed on the ops/ directory which is NOT where GIMP 2.10 looks for plug-ins. You need to navigate to the ops/ directory (its the optional folder: Macintosh HD/opt/local/lib/gimp/2.0/plu-ins/gmic_gimp_qt) scan through that folder and find the gmic_qt file, copy that ifile into you applications folder for gimp (you have to right click on the app icon to "show contents")
Path: Mackintosh/applications/gimp (the app)/contents/resources/lib/gimp/2.0/plug-ins once you are in that folder, you can copy the gmic_gimp_qt file by dragging it in.
Restart your Mac, open GIMP and you'll see the GMIC plug-in in the filters folder at the very bottom; it's greyed out until there is an image to work on.
Whew-it took me forever to figure this out. So far working OK. Still seeing if there are other files that need to be copied.
I think this may work for other, later OS's too, and maybe you don't need to do this for the latest GIMP update 2.10.33?
Anyway, I hope this helps
I am new in this forum. I use a Huion Tablet H950P, since the update to Gimp 2.10.36 my lines look like the screenshot. Very pixelated. I haven't done much with brushes in Gimp so far, however the strokes look terrible compared to results in other programs. Can anyone help me?
The original script is for LightZone and GIMP, which works nicely, from GIMP to LZ and back to GIMP
So my changes works nicely from GIMP to Darktable, but to get back from Darktable to GIMP again, I got an error
Any idea, help? I can't think anymore my head gets narrow vision now and is on fire
the code I did some change for Darktable:
Code:
#!/usr/bin/env python
'''
Lightzone.py
call LightZone passing the active layer as a temp file.

New here (architect doing building illustrations) and searched but could not find anything. New to GIMP and trying to use an effect similar to Photoshop ripple effect which I used to convert vector exported lines into a "jiggled" effect to make them look hand drawn (CAD drawing to render like traced by hand). Not looking for photo to pencil sketch or anything like that. The ripple effect in Photoshop is pretty straight forward, only choosing percent of "jiggle" and medium or large effect. The ripple filter in GIMP does not achieve anything like the photoshop ripple. The imported images are typically black and white. Looked across the web and everything is about converting photos into a pencil like sketch but the lines are not "squiggly".
Help please
