Using windows 10
2.9.5 only Gimp I can use
Issues with Wacom tablet (Intuous3, 6x8) =

• Only pen will place cursor in desired position
  
• Only pen will draw, paint and edit in desired area
  
• Mouse will not place cursor where desired
  
• I've upgraded and installed multiple versions of Wacom drivers
  

Over the year a lot of xcf files have accumulated on the hard disk. Sometimes the names do not make sense, I do not know which file to delete.
Am using Gimp on Linuxmint and in the file browser it does not show miniature images. I have to open each file with Gimp to see what it contains and then delete it or not.
Question: Is there a viewer for xcf file format to quickly get an idea of the image and decide if to delete or not?

Long time user of Gimp.. But it recently started acting up. I have reinstalled in hopes of fixing the issue, but that didn't help.
While using the program, after about 10-15 minutes, It stops.

i cannot install (not viewed in the filters or scripts list) beautify plugin even i did all what the owner said in read file . ! and the owner did not answer on github ,,Or, in the truest sense, forgotten, because it has been a long time ..

I scan a black ink drawing on white paper. If I'm using a bucket fill, what are the best settings so that the black lines are preserved and dominant? Normally I don't have any problem - I just make sure the lines as thick and dark before I scan. However, on my most recent drawing, the bucket fill swallowed up the lines more than normal - I can only guess that my settings were somehow changed (unbeknownst to me) from what I am used to. I usually just set the bucket threshold to 90 and it does a pretty good job. Thanks for any suggestions!

Hi,

I wrote a C based GIMP plugin to cleanup text scans done with a camera.
Some of these scans, esp. of books tend to have darker and lighter areas on the page , and these don't work well when you try to use a thresholding tool on your text.
The plugin I wrote find the background level dynamically for each small part of the picture, by dividng the picture into squares whose radius is the inner_level parameter. For each square, the average level is calculated on a square whose radius is the kernel_size parameter (and is larger than the inner_size). A histogram is made o all the pixel values within the kernel area, and the most popular one is assumed to be the background level.
The next darker histogram peak is assumed to be the text color, and any pixel brighter than the text brightness (plus the threshold adjust) is squashed to white.
The result is the original text in its original brightness, plus a full white background, suitable for printing.
I forgot to add that the filter first converts everything to grey scale.

The plugin is in: Gimp-clean-text-photos
(Sorry, binaries are windows-only (x86), but full source code is provided).

Using GIMP threshold tool :
You can easily see that even if you let part of the picture become black, some other section is still too bright.
No global threshold level across all the picture can separate all the text from the background.

Using my plugin (Using a kernel size of 40, inner size 3, and threshold ajust is -12).

Increasing the kernel size increases the are over which the averaging is made, You want it to be at least as large as the text rows height so that the dark letters will never become the majority pixels instead of the background.
Increasing the inner_size makes things faster since more pixels are calculated for each square,
Changing the threshold_asjust controls the offset from the 2nd histogram peak, effectively turning this to a brighness  control.

I used it to clean up hundreds of text scans done using a simple pocket camera of open books where some of the pages are darker or have shadows. The objective was to get pictures that have a white background duitable for printing on a B/W laser printer, without losing text clarity.

Hope you find this useful.

I'm writing a plugin to call python-fu-heal-selection with inputs of the file and the points defining the polygon selection, but cannot get the polygon selection to work.  I have tried using the square polygon select and it works fine, but the generic polygon selection does not accept my input; what's wrong with my script?

Hello everyone!

When you are creating a new image and specifying the size. In the advanced options if I want to make something at 4k resolution should I bump up the resolution in the advanced options?

   

Thanks in advance for the information

Hello,

I have a couple guide lines on my canvas that are misplaced and annoying me, but I can't seem to get rid of them:




From what I recall, I think I should be able to hover over them, and the mouse icon should turn into a grabby thing that indicates I can click and drag the guide lines over to the ruler where they will disappear, but it's not doing so. For example, if I'm on the pencil tool and I hover over the guide line, the icon remains the pencil tool. If I click on the guide line, I just create a mark like the pencil tool is supposed to do. Thus, I can't seem to get rid of them.

Do I need to activate a specific tool in order to grab them or make them disappear? Is there some other way of making them disappear? Am I remembering correctly (that the mouse icon should turn into a grabby thing) and my instance of Gimp is somehow corrupt?

Thanks.

Hello everybody (: I am trying to create a selection and an image with square/rectangles with cropped corners. Something like this:
