  Reduce image to simple color palette?
Posted by: Fleas - 11-11-2023, 03:58 PM - Forum: General questions - Replies (2)

I was just wondering if anyone had any tips on how to "flatten" an image's colors to give it less depth and feel more like an 8-bit sprite.  Here is an example of what I'm working with:

[Image: $Enemy-Knight.png]  original    [Image: $Enemy-Knight1.png] edited

I have a few hundred of these types of images so I'd like to know if there is a way to easily reduce all the different shades of green to only one green.  Same with brown, etc.  Using tools like posterize, threshold, and so on tend to pick up the wrong parts of the image and I would be doing tons of edits either way.

Brick start_gimp-2.10.bat - Installation
Posted by: Krikor - 11-10-2023, 04:00 PM - Forum: Installation and usage - Replies (8)

Hi,

I downloaded the Samj Portable 2.10.32 version and am carefully analyzing how I will proceed to change the version.

The first thing that is different that I found is the existence of the start_gimp-2.10.bat file, which does not exist in my version in use.

So my question is:

Why this .bat file if there is nothing like that in the current version?
When will it be executed?
Should I keep it or can I delete it?

Here the contents of the file:

set GMIC_PATH=%CD%\GMIC_Filters
set GIMP2_DIRECTORY=%CD%\Preferences
start /B %CD%\bin\gimp-2.10.exe

Last but not least!

Is there a way for me to test this new version (2.10.32) without having to first uninstall the current version (2.10.28) and so that there is no conflict between them (shared use of files, etc.)?

Grateful!

  Changes in 2024 for Ubuntu
Posted by: Tas_mania - 11-09-2023, 10:19 PM - Forum: Alternate Gimp packagings - Replies (14)

The Register has reported changes in the 2024 Ubuntu LTS system.

There will be a 'Core Desktop' and an 'Ubuntu Core' edition with a totally locked admin file system. I'm confused already, I hope they come-up with different names?

Quote:it's entirely built with a single packaging system: Ubuntu's Snap.

My experience is Snap is slower to load on older systems. Linux Mint is based on Ubuntu but does not use Snap. Which direction will they go?

  Takes Forever to EXPORT an image
Posted by: OldSargeDaleD - 11-09-2023, 07:13 PM - Forum: General questions - Replies (6)

Dell XPS 8940
11th Gen Intel® Core™ i9-11900
32.0 GB 
Windows 11 Pro

I open a graphic image (anything from a JPG to a PNG to a TIFF)
I work on the file -- many times, simply cropping something out of the larger image
I Click File, I click Export

I just did this, creating a headshot for an Avatar on my genealogy software.
It took me 7 (count 'em SEVEN) attempts to get the file name into the input box and get it exported.
Gimp stalled out, it took me out of the Export dialog box and back to the main screen with my cropped image
I'd try again, and again, etc -- the program would go into "Not Responding" then it would time out (again) and I'd have to start over

Any suggestion?? 
Thanks 
Dale

  MacOS Pinch to zoom
Posted by: Gimp_charles - 11-09-2023, 02:08 AM - Forum: General questions - Replies (3)

Hello. I thought for sure there would be a bunch of questions about this, but only found scattered results online most referring to linux.

Info:

Gimp 2.10.34
MacOS Monterey 12.2.1
Macbook Pro (2019)
Gimp user since: 2010

Trying to find a way to enable pinch to zoom in and out. I know it wasn't available for many years so had basically given up on it, but wondered if it had been implemented recently. I saw a couple random posts online that people were able to do it, so I started to wonder if it's a problem with my computer settings. Or did I misinterpret the posts I saw, and pinch-to-zoom isn't possible on MacOS at all?

Secondary question, if it's not possible in gimp, is there a 3rd party plug in that accomplishes this?

Any help is appreciated. Thank you so much.

Charles

Photo Moiré or "wavy artifacts"
Posted by: sbalbarbin - 11-07-2023, 10:59 PM - Forum: General questions - Replies (4)

Hi all,

using GIMP 2.10.34 on Win 10

I have been getting annoying wavy lines (I would describe them as, you know those topographical map of mountains, that shows the difference of heights) that actually come from the gradual transparency of a layer after using the Eraser tool. Basically, using the Eraser tool, with a Force of 25% ish and Hardness of 13% ish (actually, whatever these settings are, it does it anyway). Attached is a screenshot of the entire GIMP layout (you will see all the Eraser settings). Only 2 layers active, so basically the one on top was opaque and I'm simply slowly and smoothly erasing it to reveal the layer under. At some point, I do want the top layer to be completely showing the one under it, but I do want a certain "gradient", and that thing happens right at the gradual transparency.

I once had that problem, few weeks back. It was the same problematic result, only, it came from duplicating a text layer and applying a gaussian blur on the layer below, in order to create a glow like effect. A friend of mine told me: check to see if you're in 8 bit Integer precision, and put it higher if it is. I actually was at 8, and I put it at 16 bits and this problem disappeared. So yesterday, I was, wait a minute, I suddenly have this problem but I'm in 32 bit?

So I'm confuse here... Anyone knows what causes this (I mean I know where it comes from) but is this a "normal GIMP" thing I will have to live with? Is there a way to get rid of it once you created it? Or is there a workaround to make sure I wouldn't get this?

Thanx a bunch in advance

Stef

  Layer Mask Logic
Posted by: festus - 11-07-2023, 08:23 PM - Forum: General questions - Replies (1)

Hello,
I am wondering what the logic/reasoning is behind the use of layer masks.
Specifically, why, when you apply a mask to an image and you brush it, does the color from the below image appear?
Thanks,
fh

  Use unique image in two or more layes
Posted by: Alejandro80 - 11-07-2023, 09:25 AM - Forum: General questions - Replies (5)

Hi,

I need to use one single image, and replicate it in different parts of the canva. So when I change the image, all the replication will auto change.

Please see the attached image as an example, where I have multiple layers showing different red dots across the canva.

Now I need to change this red dot to a different image, but I do not wish to go through all layers changing one by one. I would like to change the red dot in one single place, and affect all layers.

Is it possible to do something like that in Gimp?

Thank you in advance.


Please let me know if the explanation is not 100% clear. Thank you again.

  Autocad hatch
Posted by: Gabe - 11-06-2023, 01:28 PM - Forum: General questions - Replies (3)

So I'm building a custom Cad hatch fill pattern for a software I use and like to make the individual travertine stones look like they have a little bit of depth. See attached. I was able to piece together one single stone with three or four different actions but, what a pain. Anyone know a quick way to do this?
