It does work, but I find I have to:
- hunt for the dialogue box centre screen but behind the main GIMP window.
- move it to a position beside the main GIMP window 
- click on the target image in the main window
- double click on OK in the border dialogue box
- sometimes repeat the last two steps once or twice more before anything happens
I am using Mac OS-X Ventura and GIMP 2.10.

I am completely at the starting block wrt scripting, but if anyone is in a position to correct this behaviour for a future update, please could they also consider adding:
- tool preserves current settings (width, colour) for next use
- dialogue box opens where you last left it, and floating above (overlaying) main GIMP window.

Hey all, this is my first post here, although I have used Gimp for a long time for simple things.

I have problem that I think Gimp could help me solved, but I'm not sure how. I have an old service manual scanned, in a very good shape in general, but would be great if I can bring it to almost perfection. I think there are three things that could improve the current quality from an 80% to a 95% (subjective numbers). These things are:

• Remove all single pixel marks. The document has in the background some single pixels (over the white background). Removing al those would be a large improvement.
  
• Straighten out the pages. Some pages are not perfectly "vertical", so detecting the pages that are at an angle and rotating them would also be a huge improvement.
  
• Use OCR to read the text and replace the some how "broken" characters with newly rendered ones of the same font and size.
  

• PDF to individual images
  
• Process each image
  
• List of images to PDF

Hi,

I was playing around with my settings, as I always want JPG's to export at 100% quality (it always seems to want to downgrade to 90%?). Anyway - now when I export an image as a .jpg I get a corrupted image. Here is my settings:

(sorry, I don't seem to be able to embed images via , and the upload attachment doesn't seem to work?)

Anyhow - if I look at the generated .jpg file in Notepad++, I can see it has the right start:

So I'm unsure whats going on :/ When I try and open it in Photos I get:

Any suggestions? I've tried to do a "reset" of the settings but that doesn't seem to help :/

UPDATE: I just installed 2.99.14 beta, and it showed:

This is a development version of GIMP.  Debug messages may appear here.

Do not know if it is a script or plugin. Can someone attach this here please or link me to where I may find it?

Put the file in

Create the folder "plug-ins" if it doesn't exist.

Just thought I'd post this here - I'm not sure where to put plugins with the repository gone but this is somewhere.

Just made a Python script plug-in that does palette swaps for pixel art that's RGB* and not indexed. Available on GitHub here.
It recolours the current layer, in one of two modes:

1. If given another layer, it identifies the unique colours in both it and the current layer, sorts each of them in order of RGB value, then maps them across.
          
   
2. If given 2 1-pixel-high layers, it builds a map out of them, and recolours everything in the current layer the colour of pixel 1 of the 'subset' layer the colour of pixel 1 of the 'sample' layer. Then continues through.
          
   

I have been trying to create a simple circle image with semi transparency, however when exported to png the semi transparent areas are no longer semi transparent except in some programs.

I started off in windows, and all my png exports there would display as fully solid when imported into the game engine I was playing with.  So I checked them in irfanview, and chrome and it displayed as solid in both of those programs as well.

I switched to linux and found that the exported pngs will show the semi transparent area when opened in Viewnor or Image Viewer but the other image viewer applications showed it as solid, including in chrome and firefox.  In the image Viewnior is on the left, the Gimp image is in the center, with firefox and chrome on the right.



How do I export the png to properly preserve the semi transparency in a universal manner?

I the grid makes it easy to create patterns, but the problem is that the half the squares of the grid at the bottom and on the right are outside the view, which makes the texture non-tilable. is it possible to do something about this?

I doesn't seem to be that bad with grid distance 40, what is the best setting?

Hi all,

I'm attempting to write a python script that palette swaps an un-indexed image, as sample colorize doesn't quite seem to have a way to force zero interpolation between colours.

I've got code that iterates across a pixel region pixel-by-pixel using the RowIterator from the colorxhtml.py script, finds the unique colours, arranges them by brightness, then uses gimp_image_select_color and gimp_edit_bucket_fill to replace the colours from drawable 1 with the colours from drawable 2, exactly, in order. All good.

The problem is iterating across the drawables takes way longer than it should - about 30 seconds for a ~250x250px layer. That's a bit much. Is there a way to get a list of unique pixel RGB values easily (ignoring transparency)? The histogram functions seem to work on individual channels.

I guess I could do a nested histogram in 1 channel, select areas for each of the values it took, then histogram each of those sub-areas in the next channel, then repeat again, but that seems like it'd be even less efficient!

Edit: Argh, sorry, I meant to post this in scripting! I don't seem to have the rights to delete it and repost, apologies.

How does one disable the auto update in Gimp 2.8?
I like 2.8. I know where everything that I use is. I DON"T want to take the time to learn where everything moved to.
If at some time I need a feature in Gimp 10 then at that time I will update to that version, until that time I'm quite happy
with the version I'm trying to run.



Thank You
