If I have a tree on a lawn, for example, and I add a cast shadow on the grass, how can I accurately depict the shadow if it hits a vertical wall and climbs upward?

Hi all,

I'm learning Python as I go along in the Gimp. Can somebody get me going on this one please?

I have a few variables loaded with figures. (blur is for example 10 and contrast 0.15). I would like to set a layer name, so that later I can save the layer with a filename based on the layer name.

But how do I combine fixed text and variables? It must be something like this, but how exactly?

The above was the answer to a question I found in reddit thanks to a similar quest of mine. I'm set out to do just that, and my lackings on Python programming are very nicely being covered by ChatGPT.

I have text layers in an xcf file with descriptive names and at this point, all I want to do is replace the text in them programmatically from a python script..

Chat GPT has already come up with some python code but it's throwing up a crucial error right at the beginning:

Novice gimp user

I had a previous version of gimp along with some plugin i assume

I could open 10 images as layers, crop and then export all layers. I cannot seem to remember what plugin that was if it even was a plugin. The only thing i remember is that the output folder was always in system 32

Any clue what it might have been?

Have a printer requesting 8.5"x11", 300 dpi, 1/8" bleed.

Have a GIMP doc at 2625x3375 and 300 ppi. Printer says it's coming up as wrong size and 72 dpi. 

Am I missing something or are ppi and dpi not comparable?

Hi, I am working on an icon theme for Ubuntu. It is based on Yaru ( the default icon theme ). The difficult part is that there are many sizes of PNGs that Yaru ask for each image.

I was wondering if there can be some script or so that can resize an image into all Yaru-compatible icon sizes?  Something like we have for iconify.

   

An image needs to be in 256, 48, 3, 24, 22, 16 and 8 sizes for the icon theme to work properly.

For now, I am using a 256x256 for all. It causes burr ing at edges, in some cases, info windows show a big image than a small icon due to the parent image size.

Any help would be great. Thanks.

Wondering if someone could give me a little help.  I used an stl i modeled to create a grayscale heightmap for CNC carving but the outer edges are too steep (see red circle).


I figured I could fix this by applying a gradient around the boundary selection of the image in gIMP to soften the edge between my greyscale image and the black background.

After some google searching I saw there was a tutorial for gradient border select, and the image looks to be similar to the affect I'm trying to achieve, but it was on gimplearn, which seems to no longer exist.

I've included pictures of the greyscale image, what the result is in my carving software, and a picture of the effect i'm trying to achieve.

Any and all help appreciated!

Hey everyone, I'm new to GIMP and I usually just google my questions and get my answers pretty quickly, however, this issue I haven't found any answers for and its one that affects the functionality of my work process. 

I usually resize covers for paperbacks and hardcovers for Amazon and they have precise measurements for what they want as the covers. 

Usually on photoshop, I could get the measurement down to the third decimal place without any issues, this is on my PC experience. However, I'm now on a Mac and I'm using GIMP and when I try to do the same for the resize, once I set it and leave the numbers, it rounds up, so 13.025 inches becomes 13.030 inches and 9.917 inches becomes 9.920 inches. 

This won't do as Amazon would come back with an error that the size is still unmatched. 

How do I ensure that it stays at the exact numbers I selected?

Any assistance would be most appreciated. Enjoying GIMP as an alternative to Photoshop at the moment and want to continue to do so.

For a school project, I need to make a linear gradient go from a color to transparent. I'm no stranger to using Gimp and I know the steps I need to take in order to achieve such an effect but a strange issue has been occurring. There's this weird dithering effect on the side that is supposed to be transparent.

I already unchecked the dithering option in the gradient tools but the effect still persists. I've looked up tutorials but none really seem to have this issue. I've even reinstalled Gimp but nothings changed. Does anyone have any idea of what's going on or what I'm doing wrong?
