From now on, one can not use older versions of photoshop that one bought in the past !! So GIMP is now curtainly a good replacement for those with a small budget.

I do not remember whether this question was already discussed, hence I apologize in advance if so.
Assume an image has been "quantized" using mode indexed (then back to RGB).
The image shows -for example- areas of 8 different colors (if 8 was used while temporarily converting it to indexed).
But the number of separated color areas is often as expected greater than 8, because there are areas of the same color not contiguous, for example again we see 12 separated areas.
Interactively one may use the fuzzy select tool to work on each separated area, but from inside a script I don't see an easy way to do the same, because the gimp_image_select_color considers all together -as expected- the areas having the same colors, and the gimp_image_select_contiguous_color requires an x,y identifying a pixel position.
Is there a way to access separately each area without using a complex scan of pixels in the image to identify each of the 12 separated areas? 
Many thanks.

Hello Everyone: I would like to be able to design/create decorative lines, such as would be used in a document to separate content or underline a heading. See attached examples. Does any know of a technique or tutorial or plugin that would accomplish this sort of thing in GIMP?

Thanks. . .

Hi,


I was wondering if it is possible to create a reference grid. I have a couple of photos...different sizes...and would like to render a grid every 1cm. I managed to do that with Render-Pattern-Grid....however I would like to have a notation on the side so I can refer to the box in the grid by using references such as A1, B4 etc...Do you think it is possible?

Hello,

There is a page on wikipeda on contrast limited adaptative histogram equalization :
https://en.wikipedia.org/wiki/Adaptive_h...ualization

There is an implementation of contrast limited adaptative histogram equalization on Imagej (Plugins =>Filter => Enhance Local Contrast) with settings for blocksize, histogram bins, max slope. 

Imagemagick also can do contrast limited adaptative histogram equalization,  i have also found it on github :
https://imagemagick.org/script/clahe.php
https://github.com/erich666/GraphicsGems...iv/clahe.c

I don't know equivalent action in Gimp, similar but not the same are tone mapping algorithm like Mantiuk, Reinhard, fattal. Maybe this algorithm can be ported to Gimp as plugin, filter or Gegl action.

On some picture it can be useful to have a better contrast with blocksize to match length of picture and smaller or to get drawing effect with very smaller blocksize and histogram bins.

Here for instance a 387x259 photo with Imagej and different settings :
First row Original - settings blocksize 387, histogram bins 256, max slope 3
Second row 60/60/3 30/30/3

Edits in Photoshop such as Exposure, Curves, and Hue apply a layer over the original image making it a more versatile experience, to where reordering edit layers can produce a different outcome, and allowing one to constantly return to one specific edit after making other ones and altering it. Does GIMP work in this fashion? Or is it something too advanced for me to figure out?

I'm using GIMP through the Linux addition to my Chromebook as a photo editor since I obviously cannot install Photoshop or want to pay for it. I have no issue doing the basics and I know how layers and their opacities work but it's pretty much anything in the Color tab that I don't understand to do in a versatile manner similar to Photoshop.

Greetings,

I created an animation GIF which has 500 frames.It is taking too long to unoptimize and use interleave layer plugin. Even after waiting to complete the plugin execution, When trying to save it, GIMP freezes with message "not responding".

I have enough space on my disk to save the file. The final file size is about 1.5 GB.

Any pointers on how to improve the performance would be helpful.

Hey, y'all. So, from this video game box art case cover, I have to copy the word "Trilogy" and paste it. Then I should rename "Remastered" as well. So that way, the same texts and colors I wanna keep them like that is to type it for myself. Do you know how to get into it?

Moving layers comes up frequently with beginners so a very quick look some options.

Moving layers from one image to another
1. click-n-drag
2. copy and paste

Move that new layer around the canvas 
3. A floating layer is just another layer.
4. The Move tool.
5. Anchor a layer or make a new layer

Moving a text layer
6. Use the move tool
7. Use Ctrl-Alt with the active text tool.

Hello everyone!

I need the effect you see in the image for pictures, the original idea is to use a cutting plotter ...I tried lots of options and I need to know if there is any plugin that could give me that kind of result.
Any help would be really appreciated
Thanks a lot
Best regards
