  Gimp Layer Mask
Posted by: iconwilly - 02-14-2023, 08:52 AM - Forum: General questions - Replies (14)

When I made an image in GIMP I overlayed a paper texture onto my photo making the image look like it's made of paper.
But when I transfered the image to VTF or made it my computer background, the paper texture I added seems to be missing, is there a way to add this texture to the image so it looks like this no matter what, when I put it in VTF or any other software.

Thanks.

  Gimpscripter plug in for 2.10?
Posted by: notsogoodyet - 02-13-2023, 10:13 PM - Forum: General questions - Replies (2)

Hello all, I'm a new programmer and somewhat experienced GIMP user. After doing some research into Python Fu I was excited to read about this Gimpscripter plug-in. But when I install it, it shows up in the filter bar - I click on it - nothing happens. I can't seem to figure out if I've installed it wrong or if this plug-in doesn't work on 2.10. 

Has anyone here used Gimpscripter on GIMP 2.10? 
Any tips on why the plug-in might show up but the GUI isn't showing up?

I've extracted the Gimpscripter files like this
AppData
   Roaming
      GIMP
         2.10
            plug-ins
               Gimpscripter.py
               Gimpscripter(Folder)
                  gui(Folder)
                  mockmenu(Folder)
                Doc(Folder)

Any help is greatly appreciated!

  I am new just my photo on back ground
Posted by: Holographic Breathing - 02-13-2023, 02:41 PM - Forum: General questions - Replies (3)

Hi I am new to this.

I have a nice photo of myself and with gimp I have cut out the backgrounds and I think the background is now transparent.
The photo is w1008 x h961

I want to add the photo with the transparent background to a larger background -  w18 66 x h9 61

I have saved a background of this size in white and would like to change it to colour that I would like and then put my picture with the transparent background on the top.

I would really like some help to achieving this because I'm getting nowhere.

Many thanks in advance to anyone who helps.

  Shadow question
Posted by: sl60 - 02-13-2023, 02:48 AM - Forum: General questions - Replies (4)

If I have a tree on a lawn, for example, and I add a cast shadow on the grass, how can I accurately depict the shadow if it hits a vertical wall and climbs upward?

Question Concatenate a layer name with fixed text and variables
Posted by: tkemmere - 02-11-2023, 05:24 PM - Forum: Scripting questions - Replies (2)

Hi all,

I'm learning Python as I go along in the Gimp. Can somebody get me going on this one please?

I have a few variables loaded with figures. (blur is for example 10 and contrast 0.15). I would like to set a layer name, so that later I can save the layer with a filename based on the layer name.

But how do I combine fixed text and variables? It must be something like this, but how exactly?

Code:
pdb.gimp_item_set_name(new_layer, "Blur "+{blur}+"contrast "+{contrast})

I would like the layer name to be "Blur 10 contrast 0.15".

I also tried with "&" but that didn't work either. Nor did it without the "{}".

Am I close? Thanks!  Smile

  Programmatic XCF text layer editing
Posted by: Anthony Buff - 02-11-2023, 03:40 PM - Forum: Scripting questions - Replies (9)

[Image: Perfect-Fit.png]
The above was the answer to a question I found in reddit thanks to a similar quest of mine. I'm set out to do just that, and my lackings on Python programming are very nicely being covered by ChatGPT.

I have text layers in an xcf file with descriptive names and at this point, all I want to do is replace the text in them programmatically from a python script..

Chat GPT has already come up with some python code but it's throwing up a crucial error right at the beginning:

Code:
import gimpfu

line 1, in <module> import gimpfu ModuleNotFoundError: No module named 'gimpfu'

Then Chat GPT suggested this:
Code:
import sys
sys.path.append("/usr/lib/gimp/2.0/python")
import gimpfu

Same error pretty much:
line 3, in <module> import gimpfu ModuleNotFoundError: No module named 'gimpfu'

Chat GPT suggested to find the location for gimpfu.py

Code:
find / -name gimpfu.py 2>/dev/null

That rendered nothing in my terminal. I'm on bullseye, MX Linux, and GIMP is installed from the repository. I can reinstall should that be the suggestion. I'm on GIMP 2.10.28


Any ideas as to how to go about this? Are there any sample files that could show the editing of an existing text laxer? But then, How can I get python to import the library that talks to the GIMPs API?

  [split] GIMP crashes randomly
Posted by: rickk - 02-11-2023, 07:33 AM - Forum: General questions - Replies (21)

What I have noticed while working with canvas size 16,000 x 11,000...some operations take an especially long time to conclude, making Gimp appear "locked", although it'd actually chuffing away.

For example, a bucket fill operation, even within a relatively small target area of the larger picture, for instance only 150x 200 pixels, can take 45 seconds to actually paint the target.  My guess is that's because Gimp has to calculate it''s task relative to pixel 1;1 of the graphic, so there is a lot of heavy lifting going on under the covers, despite the appearance of a simple task. Paths on really large canvasses take  a long time to process, as well.

In fact, I've been getting a surprising amount of outright crashes when stroking a path on large canvases, more so than I've ever experienced with Gimp before,  which is heart breaking when I've got considerable work in progress that just goes "poof" along with it.
What I've done is to modify my workfow, performing all the other "non-path" tasks as a group, then saving that  as an interim work, before embarking on any extensive path work.... saving paths for last....which the strategy has eliminated a lot of frustration.


I've been knitting "tiles" together of an old map that  I found in a multi page format PDF online source.  Importing into Gimp at 600 PPI,  and then touching up the join areas.   And it was going so well I decided to expand my work, ultimately enlarging the canvas to 16,000 x 14,000....whereafter Gimp  got REALLY crash prone...crashed like half a dozen times just this afternoon. But having learned the hard way what to expect, I just saved a copy before plotting any path, just to be on the safe side.

Probably need to buy a new laptop, my current machine is maxxed at 8 GB ram..

  Cropping multiple images and exporting all layers
Posted by: PHDIKOULAS - 02-10-2023, 10:28 AM - Forum: General questions - Replies (3)

Novice gimp user

I had a previous version of gimp along with some plugin i assume

I could open 10 images as layers, crop and then export all layers. I cannot seem to remember what plugin that was if it even was a plugin. The only thing i remember is that the output folder was always in system 32

Any clue what it might have been?

  DPI vs PPI
Posted by: Wallahoopi - 02-09-2023, 08:40 PM - Forum: General questions - Replies (2)

Have a printer requesting 8.5"x11", 300 dpi, 1/8" bleed.

Have a GIMP doc at 2625x3375 and 300 ppi. Printer says it's coming up as wrong size and 72 dpi. 

Am I missing something or are ppi and dpi not comparable?
