Hi everyone,

I'm a new user of GIMP so apologies if I have missed something obvious. I am trying to make a texture file (skidmarks on a road). I need only the rubber tyre markings to be visible on an otherwise transparent image so it blends into the base road texture underneath (hope this makes sense). The file type must be DDS for best in-game performance (PNG is hardware intensive to render, DDS is not). The image I have made exports perfectly to PNG, with black tyre marks on a transparent background, however when exporting to DDS format it outputs a completely black image.

I have tried all possible DDS output combinations (compressions and formats) with no improvement. I believe the best output should be using "Alpha Exponent (DXT5)" compression option but happy to be corrected on this. Not using Mipmaps (but should I? If so, how?).

I have tried many different combinations of Alpha layers, image layers, Alpha channels etc.

Screenshots of my latest attempt below (working PNG output, fully black DDS output)

Can anyone point me in the right direction?

Let me know if you need me to provide any more info.

Thanks in advance!

I have had this thing as my screenlocker image for a couple of weeks now (seems to be a standard Windows10 image), and I just noticed how heavily photoshopped it was.

   

Hi all.

tl;dr

Photo edits don't have the desired results. Probably because when I import photos into Gimp, the brightness, contrast, saturation (etc.) change subtly but perceptibly. I think this is due to Color / Colour Profiles(?) What am I doing wrong, and how can I get more predictable results? Thank you in advance.

Apologies for what feel like pretty "noob" questions. (And further apologies if they've been answered 1,000 times already; I searched the forum, but maybe my search fu is lacking).

The problem: 

I take photos with my smartphone, then import the jpegs into Gimp for post-processing. But they look different in Gimp - flatter, greyer, less bold - than they do in the File Browser (Finder; I'm using macOS on a MacBook pro). I think this is due to the Colo(u)r Profile: Finder says "Colour profile: sRGB IEC61966-2.1" but AFAICT Gimp is using sRGB(?)

I've experimented with Image > Colour Management > Assign Colour Profile... and Convert Colour Profile... ...but I can't discern any difference, so I assume I'm using them wrong.

Q1. Am I right in my assumption: is the Colour Profile the problem?
Q2. I want the changes I make in Gimp to accurately reflect what I'll see in Finder; what's the best way to achieve this?

Bonus question (...possibly opening a can of worms?): if my ultimate goal is to post the results online, does it matter which colour profile I use...?

Any help gratefully received  

P.S. macOS, Gimp 2.10

I'm new to this program and for some reason i cant get my 2nd layer to resize.
what am i doing wrong any help would be great.

I'm new to GIMP and have read that the resynthesizer plug-in is an easier way of removing an object from a photo while maintaining the background so I tried to download it. I'm using an M1 Macbook Air running GIMP v2.10.22 and I've followed each step from Davies Media Design Tutorial (https://www.youtube.com/watch?v=MiE-buxZij4&t=287s). However when I try to use the plug-in (Filters>Enhance>Heal Selection), a dialog box always appears saying this:

An error occurred running python_fu_heal_selection
error: procedure not found
More Information:

Any help would be appreciated!

Nice to meet you.

I tried to install G'MIC by referring to the post on the page below.

http://gimpchat.com/viewtopic.php?f=28&t=17566

Quote:Use the package: https://github.com/aferrero2707/gimp-pl ... 10-osx.tgz Unpack it and move folder GMIC and exe gmic_gimp_qt (hence the content of the tgz) to ~ / Library / Application \ Support / GIMP / 2.10 / plug-ins / 

I'm trying to keep my 2.8 and not update to the 2.10. but i can't find a way to do it, please help?

Hello, I'll would like to know how made a stroke path dotted with circle dots rather than square dots.

I'll don't find any circle dots in line style only square.

In fact I'll would like to make bolts along a path.

Thanks by advance for your help.

Hi all,

For one of my projects I would like to extract a specific part of a path, and make it a separate path to move around by itself. I have included some screenshots and the corresponding xcf file in the attachments.

One method I have already tried is with using the the ofn-path-edits.zip, to break apart all paths, and toggle the lock button and then move them around. This works, however; in my actual projects, I'm dealing with several hundred segments, all merged into one path. If I have totally break this down and, locate the right segments, toggle the ones I want to use, and then start moving them around, this is extremely time consuming.

My question;

is there a way to make a selection of a segment of a path (with some sort of free-hand tool?) to extract a specific part of a path, and make it a path by itself?
(pls see attachment for clarification).

Any help will be greatly appreciated!
Warm regards,

J-G1

I want to draw this in GIMP:

How? So far I have only come across the path tool, but I haven't found any other way other than setting anchor points by free hand. I'd like to set the coordinates of those anchor points directly. How?
