  Border left around selection when selecting by color
Posted by: Chellrose - 08-08-2024, 12:48 PM - Forum: General questions - Replies (3)

Hi,

Using GIMP 2.10.34 on Debian 12.  When I "select by color" and then either cut the selection or fill it with a different color, it leaves behind a border of the old color.  This happens with the fuzzy select too.

The antialiasing option on select is off/unchecked.  I've tried it with and without antialiasing, no change in results.

This happens even with single-color images that I've made, so I know it isn't fuzziness from some JPEG or something like that.

Steps to reproduce with own image:

1. Make 2 layers, one a white background layer and the second either white or transparent.  (This is to give a full white background to see the border easily)
2. On the top layer, make an elliptical selection.
3. Using bucket fill, fill the selection with a single color.  (Anything but white)
4. Select None
5. Using Select By Color, select the area made in step 3.  (FWIW, I'm using Select By Composite with a threshold of 20.0)
6. Either cut the selection, or fill it with a different color.

A border of the old color is clearly visible (if you filled with color, you may need to zoom in a bit to see it.)  The border appears to be 1-2 pixels wide, with varying shades (or opacities, I'm not sure) of the old color.

Can anyone tell me how to fix this?  I'd like to be able to "select by color" the whole area, and cut or fill it without leaving a border.  My searches so far yield the suggestion to turn off antialiasing in the selection, but again, I do have antialiasing off.  I've attached screenshots showing the initial colored region and the border left behind.

Thank you!

GIMP 3 no more <Vectors> but <Paths>
I just stumbled upon it > https://gitlab.gnome.org/GNOME/gimp/-/issues/11881
Might help Ofnuts (if he is not already aware) and others if one day he/they decide to port their plugins to GIMP 3.

  How to clean up full color pics for black/white print?
Posted by: abrogard - 08-07-2024, 11:30 PM - Forum: General questions - Replies (3)

we only have an old black and white office printer.

from time to time we want to print out images that are full  color or close it it.

then the printer wastes a lot of ink doing a dark background and incidentally obscuring much clarity.

is there a way to deal with this probably fairly common problem?

here is today's example:

  Python-Fu console crash
Posted by: robgos - 08-05-2024, 02:31 PM - Forum: Extending the GIMP - Replies (7)

Hi

Trying to start with Python scripting and got problem with console crash. Trying both from saved file and entering script in console, when main() function is called console crashes, saying that (translated directly from my language so in details may be little bit different, but: "An error occurred in the plug-in: "python-console.py, The plug-in, by aborting due to an error, may have corrupted the internal state of GIMP. To be safe, it is recommended to save the images and restart the program." Tried different scripts, even with empty main function.
Tried on two computers, version 2.10.38, Windows 11 Pro

Dont think it is my computer. Am just having problem with one site atm. 
Cannot see the last 11 replies on a thread of mine from my computer. Am wondering if it  is also making the whole site slow for me. Saw all I missed on my phone.
I know it is not gimp related but was hoping someone here could help me with a solution.
I was advised to remove a 'hosts file # website name'  but don't want to do that unless I know it is safe to do so. 
Any one here use windows? and where would I find the host's file if it is ok.

Photo How To Overlay A Still Image Over A Gif?
Posted by: aRandomViewer - 08-03-2024, 02:09 AM - Forum: General questions - Replies (2)

How do I put a png over a gif I have without it changing? I've found stuff where gifs can be overlayed on still images, but not the other way around. I even once attempted putting the still image on each frame of the gif, but that caused the transparent colors to add on top of each other, since some of the frames are meant to combine.

  Histogram of all visible layers
Posted by: Feliks - 08-02-2024, 03:26 PM - Forum: General questions - Replies (5)

Is it possible to see a histogram of all visible layers combined (and not only of the active layer). I want to tweak different layers and see what it does to the final result. If that is not possible, is there maybe a plugin that can do this ?
Thanks.
