Scheme Algorithm for indexed image mode
Posted by: lesolorzanov - 07-27-2023, 11:54 AM - Forum: General questions - Replies (3)

I've always been marveled at GIMP and very happy that it's so accessible.

I was wondering if I can ask, I'd like to know how indexing works and creation of a palette, it happens so quickly that I was wondering if anyone could tell me (even if roughly) how this indexing works. Or even point me to a an article or the name of the creator of this particular algorithm.

I attach an image of what I am talking about.

  Merging colors... How do it with Gimp?
Posted by: Krikor - 07-27-2023, 10:00 AM - Forum: General questions - Replies (9)

Hi,

We obtain the secondary colors by superimposing the primary colors, such that:
Red + Yellow = Orange
Blue + Red = Purple
Yellow + Blue = Green

Is there any way to produce this with The Gimp?

   

I laid each color in a layer and tried to get the secondary colors, I tried the layers modes and the composite mode, but without getting the expected results.

Thx!

  several register by python file ?
Posted by: jacques_duflos - 07-25-2023, 07:07 PM - Forum: Scripting questions - Replies (3)

I am doing a script that I want to execute very quickly with a shortcut, or more slowly with a option window. Something similar to "save" (quickly executed with ctrl+s) and "save as ..." (with a window to precise options). How should I do ?

  1. Should I do two completely separated plug-ins ?
  2. Or one plug-in with two python files in it (one importing the other I guess) ?
  3. Or can I put several register function in one python script ?
  4. other ?
I would say the third option is the best, but as I can't remember having seen such thing anywhere, I wonder if there are habits or rules about that.
The code would look like that :

Code:
from gimpfu import *

def slow_function(image, layer, other, options):
    #some code

def quick_function(image, layer):
    slow_function(image, layer, defaults, values)

register(
    "python-fu-quick-function",
    "description",
    "description",
    "Your Name",
    "Your Name",
    "2023",
    "<Image>/Filters/quick function",
    "*",
    [],
    [],
   quick_function)

register(
    "python-fu-slow-function",
    "description",
    "description",
    "Your Name",
    "Your Name",
    "2023",
    "<Image>/Filters/slow function ...",
    "*",
    [
        (PF_IMAGE,  'image',            'Image', None),
        (PF_OPTION, 'some option')],
        (PF_OPTION, 'some other option')]
    [],
    slow_function)

main()

  Resizing Images
Posted by: Azean - 07-25-2023, 03:55 PM - Forum: General questions - Replies (2)

Hello, 

I've messed around with Gimp for a few years when I need to do something but today I'm having a lot of problems using the scale tool. I have a base layer with an image, I paste in a second image that I put on its own layer that I can manipulate with the unified transform tool and rotate tools just fine but the image is too large and I wanted to scale it down with the scale tool but I am unable to just select the image I want and instead it selects the whole canvas. What am I doing wrong? I don't ever recall having this issue before so I guess I'm doing something wrong.

Cheers
Az



Never mind, I figured it out shortly after posting. In tool options Transform was set to image instead of layer *face palm*

Sorry about that, if you're a mod please delete the thread Smile

  Github for gimp plug ins
Posted by: jacques_duflos - 07-25-2023, 01:16 AM - Forum: Extending the GIMP - Replies (1)

Is it a good idea to use github for creating and using gimp plug-ins ? I guess it is very useful to share them, and for team work. But is it useful to clone a repository directly in your plug-in folder ? will it keep the plug-ins up to date ?

I just started using it but I'm still very new to it. If anyone has pieces of advice, experience or whatever  please share

  How do I make(more than one) straight line?
Posted by: Zio - 07-23-2023, 03:17 AM - Forum: General questions - Replies (7)

Hello all,
Just starting out with GIMP, and have run into a problem.  I watched a tutorial video about how to make straight lines using the SHIFT key, but then when I try to make another line, that second line turns out thinner and in a faded green/blue color.  What am I doing wrong?  Huh
