Using ofn-gradient-along-path on a particular RGB image takes about 30 minutes.  Using it on the same image converted to Greyscale takes about 90 minutes.  I would like to figure out a way to speed up the script.
Is there a way to profile the script and find out what calls are taking the most time?
Perhaps the image or aspects of it are being converted back and forth between RGB and Greyscale.  Is there some sort of specific Greyscale library or functions which can avoid thrashing like that?
Any suggestions on how I might be able to approach this problem?

Hi Guys
I'm desperate for some help for what should be a simple operation. I'm creating a cover for a book with Amazon KDP. I've done this before with GIMP 2.8, but now have 2.10. When I try to insert the image I want into the book cover template it appears very small and I can't change it to fit the template. I've tried everything. I open the template in GIMP then open the image as well. I've tried copy and paste with the image, but a tiny image appears and I can't drag it to fit the template area required. I'm obviously missing something obvious. I'd be so grateful for any help.

Many thanks

Jude

Hello 

I'm just an idiot - please help me

Does someone know of a tutorial to explain how I would add 'depth' to a flat image?
In this image below, you can see the shadowing.

I can create a rectangle, and add a wave effect, which will look like a flag, but there's no depth internally


Thanks!!

First off I can not change the font! I have attached a screen shot to describe the problem

So any advice please?

Thanks

I thought it would be nice to have it to "help" people seeing things in the stack, so I made few tries and got some strange behaviors.

First, one the try did not like much the Ctrl+F after adjusting a node, GIMP got in a loop, until I needed to kill it

Then at one point from an image of 1920x1080 pixels, I got an image... take a seat... attach your seatbelt... of a whopping 11 GB new image with 33 217x 23 434 pixels and completely deformed

Before:
   

After:
   

I did save the XCF to keep the last path when I saw this huge image, if you want to try, it's reproducible every time.

I don't know if it's a good file transfer website, I was surprised that G-F accept only 1MB as files, thus searching something quick (file is 1.8MB)

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..
