I'm fairly new to GIMP, so maybe I'm doing something wrong. But when I crop an image, it leaves the pixelated background there. So when I reopen the image, you can see the area that was cropped (which shows as a white border in the attached screenshot. I have the "delete cropped pixels" box checked, so that shouldn't be happening. Can anyone suggest something I might be doing wrong?

• Worked out the math to generate a displace map
  
• Figured out that Gimp displace map doesn't work at all as described in the doc
  
• Worked out some more math to generate a displace map that pleases Gimp
  
• Eventually got some satisfactory results
  

   

   

Hi,

Starting with an image on an oversized canvas (ie. with space all around the image), I was wondering if there's to select a point on the image with the mouse and then snap this point to the centre of the canvas?

Hope this makes sense. I frequently have to centre scanned maps in this way and would like to find a way to do it quickly and precisely.

Thanks

Good day,
  I was given boxes of family albums.  Most I can separate the pictures, but others are the glue pages holding everything in place where the best I can do is remove the spiral binging and plastic overlay.  Picture counts and sizes will vary on each page.  Looking a batch scripts to separate the individual images in a scan  the most recent I see use deskew.exe to realign the images, but that doesn't seem to be around anymore.

  What are the current suggested workflows for doing this type of work.  Dust removal and color correction can happen later.  I have windows 10 macOS and Ubuntu Linux systems available so my options their are wide open.

Thank you for your time and suggestions,

-Patrick

Hello,

I would like to automatically get locations of multiple simple geometric forms from digitized maps ...

I have roughly 300 digitized maps (300 7 MB files) containing the positions of all allied and german units during the last year of world war 2. It is approximately 500 units * 300 days = 150000 locations.

Using the Gimp script-fu, I'm able to pre-process the maps and remove the backgrounds to keep the units symbols only. Attached is the light result map for the 6th of June 1944.

Is there any "simple" way, using gimp to separately detect the geometric unit symbols (rectangles with round inside, rectangles with cross inside, dashed rectangles, ...) and then get a corresponding position in the image?

I think at kind of convolutional algo ... ?

It is quite obvious for a single map to do it manually, but ... I would like to be able to insert this into a script-fu to run it automatically over the 300 map files.

I don't want to use heavy processing like AI for that ...

Thanks for your help.

Hi All

Is there way to take an outline of a shape then copy that so you just have the outline?

So example would be if you had a solid square, and you take a outline of that so you just have shape of the square. Hope that makes sense.

Have downloaded GIMP 2.10.32 - added resynthesizer plugin without any problems

When i try to use it, however, I get this


An error occurred running python_fu_heal_selection

Why, when I drop an image into GIMP, does it instantly get resized?  I know I'm probably doing something wrong.
I have an image that I want to rotate -45° and save without any further modification.
I want every pixel just as when it was loaded, just rotated.

I can't figure out what I did to my clone and heal tool.  The little x that is usually in the center of the tool selection area is now offset towards the top.  It also doesn't work like it usually does.  The whole selection area within the tool doesn't work properly.  It seems only the upper portion works properly.  I exited Gimp and came back in but that didn't fix the problem.  I can't get a screen capture because the little x inside the selection area doesn't show up.  It has gone away and come back a few times.  I can't figure out what I have done.

   

I’m looking to do some color correction on old photos, but the scans include a border made up of the album paper on which the photos are mounted along with some handwritten captions.  The album is about 65 years old and the photos are glued directly onto the album paper.  Also, many of the photos are slightly skewed.  I've attached an example.

How do I limit the enhancements to just the photo without affecting the color of the surrounding album paper?  I’m assuming there’s a masking technique that I can apply in this situation but I’m not sure what it is.

I suspect a similar question has been asked but all of my searches in the forum (and online more generally) have come up empty.
