Hi All,

I am trying to achieve a certain look on a greyscale/height map image for a cnc project I am working on.

Im new to gimp so Ill try to be explicit as Im not sure of exact terms.

I started with an image that only has two colors to my knowledge (or at least doesnt have a lot of colors so that if you looked at a height map of the image it would be mostly 0s and 1s.  I switched to greyscale mode and played with contrast and brightness to get the greyscale sharper.

This is where I am.

I am trying to figure out how to basically apply a filter (or modify the values of the pixels in some way ) over that grey scale image I created so that it becomes a height map where the highest point is in the center and as we move towards the edges of the image it gradually falls off in height.  so that you get a domed look but still retain details of the image.  Is this even a thing that makes sense? Is gimp the right program for this sort of thing?

Appreciate it!

When I read the API document of gimp_layer_new(), I'm curious about what are explicit procedure calls in the below quote. 

Quote: Other attributes such as layer mask modes, and offsets should be set with explicit procedure calls.

Quote:Attributes such as layer mode and opacity should be set with explicit procedure calls. 

Hi. I am a brand new GIMP user for about 2 days now and I have already learned a lot, thanks to excellent YT tutorials.

Windows 10 Pro 64-bit; GIMP 2.10.28

I need to install this plugin:
https://github.com/apocalyptech/gimp-text-outline

I downloaded the [color=var(--color-fg-muted)][color=var(--color-fg-default)]text-outline.py[/color][/color] file. I copied it to: 
C:\Program Files\GIMP 2\lib\gimp\2.0\plug-ins

I put in the root folder and restarted GIMP. But, the plugin does not show show under filters, decor where it is supposed to be. I  am sure I did not copy it to the right place.

Can someone please advise:
1. If I did it correctly, and
2. where to put the file for the plugin.

Thanks very much.

I must have changed the default setting somehow and now am clueless as to how to get it back. 

Drawing on a new layer with a color using paint brush works just fine. When I try to add a new color now however I can only draw on the empty space of the layer, and no longer over the color. It's as if the old color had become a seperate layer that's laid over my layer. See the two images attached.

Thanks for your help.

Hi,
I just published a tool for batch processing using spreadsheets:
https://gitlab.com/ChameleonScales/tablegimper

As far as my tests go it fully works as intended but I would like to hear from some experienced users before I make a video tutorial so that if there are high-priority corrections to make I can first do that and then make a video.

If you're up for it:

Attached to this post is a test folder you can play with. The readme in the gitlab repository should guide you all the way to being able to use tableGimper with this test folder.
If not, here is a first problem to solve!


As it is, this test folder will purposefully lead tableGimper to throw you errors so that you can see what happens when you make mistakes in the csv files.
Then, the working csv files contained in the "no-errors" folder can replace the other ones to give you a working structure for tableGimper.

Looking forward to your questions and feedback.

O I meant "thumbnails" probably not "icons"   ...so these little thumnails, pictures, whatever you call them, have ceased to appear when a file is opened.
How does one enable them.

Been using Gimp for years. The icons that appear at the top of the workspace no longer appear when a file is opened.  Am using Gimp 2.10.28.

I think gimp is using too much memory because of which I'm unable to open any other applications while using gimp. While startup of gimp, it uses only like 80 MB, but as soon as I open any file or image, it jumps directly to 500 MB and from there it only keeps increasing. Is there any way to reduce this without affecting any overall performance of gimp?

Version- 2.10.28.
Windows 8.1 (64 bit)/ 4 Gb of ram.

Images like the hundreds of craters on the moon or a cliff face with thousands of rocks with shadows sometimes look too smooth.
The Artist Filter Cartoon enhances darker areas that are distinctly darker than their neighbours and works but was not made to do this.
Is there another filter or method to darken multiple shadows?

HI all,

I recently played around with some abstract photography. I was in a state of mind that made it difficult to retrace my steps / filters / effects I applied   

I know its a long shot but I thought maybe somebody here has an idea what kind of filters / settings have this effect. Take it as a challenge

I am pretty sure I inverted the colors before applying filters, but like I said I was pretty out of it. I am not even sure if it was a filter specifically or other settings which does not make things easier . All I know for sure that it is definately that photo as I never renamed it, and I used only part of the original (cropped).  

If you do find out you have my eternal gratitude and utmost respect
