Working on an item concerning radar object detecting, I want to use a picture of a LB 13 / 40 tube. I don't want to use an existing photo from the internet, so I tried my skills with gimp and the result is this : 
   
   

Gimp 2.10.18, Linux Mint 20.3 Mate,
Does any one know if the Filter, "Leon Reset Background to White" is still available, i found it a very use full tool for converting PDF's texts backgrounds to white, i used a few years ago but cant find now to reinstall ??

I am a brand new user of GIMP and so am not familiar with the correct terminology. I searched on various permutations of this thread title but came up empty. I am not especially graphics oriented and will never be a frequent user. However, when you learn how to use a new tool, it turns out to come handy in the future for many tasks you never foresaw. 

I was steered toward GIMP by a friend who used to have Photoshop and I mentioned that I had a project in mind about making a photo collage. Because his Photoshop had died with his computer's hard drive, he suggested I look into GIMP. Well, the photo deal is on hold but I have been using the program to help create silkscreen stencils for cookie decorating. I have found several You Tube videos which really help explain how to accomplish my simple tasks much easier and quicker than the simplistic, inefficient ways I had started out using. My current dilemma concerns a logo shape which I want to make thinner. The procedure will be to screen the logo shape, in this case the script of a college name, with one color of icing. Then a reduced shape is screened over in a different color, which will hopefully yield a uniform border around the second screening.

I started with a PNG file of the logo. Using GIMP I split the file into separate files for each color. The inner color outline is too close in size to the border color. To get an outline of the inner color I followed an on-line suggestion:

LAYER > TRANSPARENCY > ALPHA TO SELECTION
SELECT > TO PATH
SELECT > NONE
[hide layer, make new layer]
EDIT > STROKE PATH in the STROKE LINE menu

This left, presumably, a STROKE LINE around the edges of the inner color. I have a background in AutoCAD. In any CAD program, OFFSETing a line refers to drawing a parallel line on whichever side of the object line you choose. If the object closed, say a square or an unfilled alphabetical letter, you end up with larger or smaller squares or letters but the centers of both the originals and offsets remain the same. With this background I had intended to OFFSET the STROKE LINE inside the current outline by several pixels. Then I intended to flood that with the inner color, thereby creating a slightly enlarged border around the now smaller inner color. But it appears that OFFSET has an entirely different meaning in GIMP.

So some specific questions:
I see the STROKE LINE I created, but don't know how to select it and verify what entity type GIMP thinks it is, i.e., is it actually a STROKE LINE?
Can a STROKE LINE be offset smaller as I described above, i.e., not scaled?
If not, what type of GIMP entity or procedure is able to accomplish this?

Thanks for any guidance,  Rick

I am looking for a tutorial how to remove Vignette effect using Gimp. I found a very good plugin https://www.vicanek.de/imageprocessing/v...rector.htm
It works perfectly with Irfan View. But when I put it in Gimp it opens but only a small part of the image is displayed.
So perhaps you know a better method to get rid of vignetting?

In docking dialog windows, is there a way to stack dialog windows on top of each other rather than have them turn into columns running the whole length of gimp?  With the "undo" window  or the layers window, having a long column is good, but with other windows I just need a box shaped window, not a long column, and would like to stack the boxes on top of one another. Would also like to be able to lengthen or shorten a dialog window even if it is docked. How does one do that? Can't seem to find documentation on this. 

Thanks in advance for any assistance..

Been using Gimp for about a week now but cant seem to find an answer for this. Im trying to put three same size circles on a page but when i move them it always leaves a faint border behind and i cant seem to remove it. I float the image to allow me to move it and then anchor down so i assume im doing this bit right but the imprint is left behind. Picture attached.

Good evening and thanks for reading a newbie question, and it's probably extremely basic and obvious.

I've downloaded Gimp 2.10.32 because I would like to make my own Blu-ray covers for my collection using a fan template of The Criterion Collection sleeves.  Over the last three weeks, I've slowly been learning about layers and changing the direction of text boxes.  I know that Rome wasn't built in a day. 

But I'm stumped in how to change the pre-loaded data within the template.  This template is pre-loaded with some basic, junk numbers for the back cover information:

2015
75 MINUTES
COLOR
MONAURAL
2:35:1 ASPECT RATIO

These figures seem to come from the "name" / "layer attributes."  When I right-click on the layer that contains this information, I get an option that says "Edit layer attributes."  This gives me a pop-up box where I can change the layer name.  The name of this layer is: 

2015 75 MINUTES COLOR MONAURAL 2.35:1 ASPECT RATIO

But whatever changes I make to that name just change the name of the layer, not the text that appears in the image.  How can I make changes to those figures so that the text of the image reads what I'd like it to?

Thanks in advance.

Updated today via the software updater on *buntu 20.04.5 to GIMP 2.10.34, I have the PPA Panda Jim (ubuntuhandbook1) and got a tiny problem when starting GIMP just after upgrade.
It says that my GEGL is too old and GIMP refuses to start.

I solved it by opening right away Synaptic package manager, searched for GEGL, selected libgegl and marked it to upgrade,
> synaptic immediately proposed me to upgrade more packages related to gegl,
> yeah, sure I agree
> Apply button for all,
once upgrade was done > GIMP started nicely  

Just sharing in case you got the same tiny problem.

Also first thing I tried first is the text color that flatpaker have problem with, Not problem detected on my side with this PPA   (yet)

   

Hello everybody  
I'm interested in colorization of old photos. Sometimes I encounter a problem with cobbled roads/streets. For example this photo taken in 1930s. How to automatically colorize it without laborius selecting some stones and makinh them reddish and others bluish? Like in this color photo? https://www.dreamstime.com/ancient-windi...e103076500

I need to increase the resolution of my company logo so when I print it on my product labels and instructions it will be more clear. The image is a small picture and I like to enlarge it for the instructions but it becomes fuzzy when I do. Can someone fix it for me and then tell me how to do it so I will know in the future?
