How do I obtain the algo/kernel/convolution mask for the various filters in gimp?

For instance, I was interested in the numbers behind  https://docs.gimp.org/en/plug-in-oilify.html

so I could customize them per my needs, and create new filters per my needs.

Howdy all,

I'm going to start fiddling with the best way to scan in and clean up aperture cards to make them as readable as possible. Has anyone solved this problem before? I expect the process would be similar for microfilm and microfiche if anyone has worked with those. 

As I sort out best practices I will share my findings here.

Thanks,

GIMP keyboard shortcuts (ps-menurc shortcuts) sometimes work sometimes not! note "i am using
theme called "dark"" and i added the "ps-menurc" to it and replaced similar file with it " and tried to add it in gimp folders like themes , plugins etc  and /user folder in c . as  a random solution! but not fixed the problem! and may work fine if i re copy the file every time before i use gimp to the theme folder !
-
even if i reset the gimp tool preferences , gimp shortcuts not always work also !

it seems that i can not change my username by "forum options" ! can that be done by admins manually like some other forums ?..

I am running on High Sierra 10.13.4 on a 27' Mac, when trying to use the heal tool or 

the clone tool right clicking on the mouse & holding Ctrl only brings up a dialogue list,

I was under the impression from the tutorials that I have viewed that this action should

activate another circle dependant on the brush size then transfer the sample from the original 

circle. What am I doing wrong please

I am a newbie to Gimp running Gimp 2.8 running High Sierra 10.13.4 When attempting to use the Healing or Clone tools right clicking

Hi,
I have been a GIMP user for many years but what happened today is new to me. I accidentally undocked the Tool Options so then I automatically tried to revert it by unclicking and clicking the single-window mode. However, the Toolbox did not return to the top with the tools in several rows but the tools are in all in one vertical line alongside the image block, and even disappearing out of the screen so many cannot be used at all... It seems it is not possible to drag it to where I would like it to be. Will you please give me some advice on how to return the toolbox back to the original position, i.e. Toolbox in the top left corner, Tool Options under it, and not one on the left and the other parallel to it?

Thanks!

Good day,

I am using the current beta. Does anyone know if there is setting to increase the size of the tool icons?

I've taken a load of photo's of old photo prints. They are not square on the photo's I have taken and some of the photos were not completely flat.

What I want to be able to do is select the four corners of the photo, square up the corners and crop to that size so end up with a nice square off straight photo.

I've tried searching but have been unable to figure this out. Any help would be appreciated.

Thanks
Andrew

Hello, I'm having trouble trying to save a "project" (xcf file) on GIMP. I get the following error: "could not seek in xcf file invalid argument". From what I managed to find online it may be because the save file size is over 2GB. I wanted to know if there are any workarounds for this issue and also know why is the XCF so big when my original image is a jpg file of only 130mb and I have barely added any features in it, just about 4 paths. The bottom part of the gimp window is showing "filename.jpg (7.9GB)" and I have no idea where did that 7.9GB came from since, like I said, I've opened a 130mb jpg image. I used to have a ~7.5GB filme with the same name as this one (higher res version) but I've deleted it already and opened gimp by right clicking the new file (130mb) and selecting "open with GIMP".

Thanks in advance.
