The fundamentals of the tartan cloth (plaid for americans) are well described on Wikipedia and are very simple. They are easy to reproduce on Gimp:

Creating the tartan "tile"

• Create a small square image (this will be your tartan "tile"). Its side must be a multiple of 4 (for instance, 40x40)
  
• Fill it with horizontal bands of color of different widths (usual tartan patterns use three colors, and there is a vertical symmetry).
  
• Duplicate the layer
  
• Rotate the top layer 90°
  
• Add a layer mask to the top layer
  
• Bucket fill the mask of the top layer with the attached TartanWarpMask pattern
  
• And there you are

This happens to me all the time. I use fuzzy select to lighten part of the background in this booking photo. But if you look, it also goes onto the guy's jacket, which I don't want.
I don't have the time to go through and manually select the area so the jacket is left out. Is there a way I can quickly unselect the area on the jacket?
Sorry if this is such a noob question and thanks in advance for any help.

meson test failed with the following ERROR mesage for gegl-0.4.30 .

What is the reason for the difference in results between stroke selection and stroke path?  Stroke selection is not perfectly round and not smooth and is twice as large as the stroke path operation performed on the same sized oval design.

Is there any way to get a smooth and true to shape result using stroke selection, or is that not the purpose of stroke selection?

Hi-

I have the latest version of OS X and Gimp 2.10.22 (revision 3).


What causes the Tool Options to pop out like in the attached pic and how do I move it back to where it was before?

Thx

Hi,

I'm using GIMP 2.8 and am contemplating whether I should upgrade to 2.10 (or not??).... but I'm on an older MBP that's a 2014 running OS Mojave. Can it handle Gimp 2.10? 

Also, if I do upgrade, will I lose anything in the different functions or will I have trouble opening my 2.8 projects after the upgrade.

Thanks!

Hi GIMPers,
I’m a scientist working on the colour of seafood. I want to get the average RGB value of the tissue I’m working on, but have it not be influenced by non-muscle tissue (fat) and not be influenced by specular reflection pixels. I’ve used the “select by color” tool to reasonably good effect (see attachments. "6 modified" is after processing, "6_cropped" is the input file), but it requires human input to select the color (around which range pixels will be selected) and the threshold (of how tight the range is). This is not adequate though for high-throughput sample processing, and not reproducible (from human decisions as above). I would like a script which:
1. Isolates the sample from the background
2. Removes pixels associated with non-muscle tissue and specular reflection pixels
3. Calculates average RGB values for remaining pixels
Step 2 could be based around a rule like: Make pixels transparent if R/G/B value lies outside “range specified by user based on color picking analysis of RGB values of unwanted pixels”.
My girlfriend coded one in Python (Github link: https://github.com/aspiringutilitybot/Pi...-of-inputs ), but I thought a GIMP script would be useful.

Hi, I was trying to create some badges as in gaming type. Some of them are really complex and has a very bright glow like outline. Something like this

   

It would be nice to know how to do this using GIMP. Thanks.

...and why you should not worry about it.

You know that your printer uses cyan, magenta, yellow (CMY) and black (K) inks and wonder about converting between the GIMP (and computer) red, green, blue (RGB) and CMYK.

If printing at home, the inkjet printer software  does the conversion. Just remember that photographs are typically displayed brighter on the computer, especially with Windows Photo Viewers and will print that bit dimmer.

If sending photographs off to a commercial printer, these days they will generally make the conversion for you, with a warning that colours will become 'more subdued'. They will still do a better job than you can do.

LOGO's and designs that are printed using offset printing where layers of colour are printed on top of each other (a subtractive printing process) are another matter.  Your painting / sticker / book cover might come back looking dull and faded.

The best way is to create your design start-to-finish using a CMYK editor such as Krita, however it is possible to use GIMP and see what a print will look like. That is soft-proofing

If you must use Gimp, then pick your colours carefully avoiding those bright greens and blues that will be affected the most.

This little video is about soft-proofing in GIMP. https://youtu.be/jyNz7-QLPLA  about 6 minutes duration.





For those that want a CMYK version of their work using Gimp then there is a plugin CYAN see: https://www.gimp-forum.net/Thread-CMYK-c...3#pid11743
