How to change one color in the image with another?

Updated today to Gimp 2.9.7 from 'buntu ppa

This is the blend (gradient) tool, The ability to paint a gradient directly onto the canvas is not new, but I do not know how long editing a gradient in place has been there. Adjusting the colour stops, now shows up straight away in the tool.
The gradient file - something.ggr does of course, have to be in your Gimp profile gradients folder, to be editable.



Developers are threatening to include this in an updated Gimp 2.8.(24?) sometime.

For a while my browser has been crashing on me or 'not responding' but eventually it did. I think I have fixed that now by resetting the browser but now Gimp is doing something very similar. Nearly every-time I run a filter within gimp (It doesn't seem to happen with GMIC) the status bar at the bottom doesn't complete. Sometimes the operations complete and often they do not. 


I don't have a screensaver running on my computer so that is not using up room. I have only used about half my storage too - over 200GB is left on it. Surely I don't use 200 hundred GB to browse the net? My question would be  - what do you think the problem is?

I am using a relatively new gimp 2.8.22
Am afraid to add any more scripts now incase my pc cannot handle it.

My OS is Windows 10 Home 32 bit

I have 256*256 image.
I would like to offset it in a way that Gimp creates 512*512 canvas with 4 images (256*256) offseted.

ello all,  I recently got into the t-shirt design hobby/business.  I downloaded gimp and have been using it to turn my hand drawn art into computer based art for Tee Spring, Society6 and many more.  The issue I'm having is that for some reason my lines (mainly the curved lines look pixelated.)  after seeing many videos on how to change the DPI on gimp I keep only seeing how to only change PPI. 

I did notice that to change the PPI it automatically changes the art design to smaller dimensions is that why I get's pixelated because its being stretched on the t-shirt?  What is also weird is that when I make the art larger to where it bleeds out of the printing zone the pixels seem to be more smooth.  (the following pictures are for examples only and not the actual design)

so my questions are:
Can I create art on gimp for t-shirts that will be printed on Society6,Tee Spring, Red Bubble etc.?  If so can someone please give me detailed instructions how to fix the issue or maybe even a video link to one.
Thank you for your time.

Help request from users of Gimp versions 2.9.x.
Does Gimp 2.9 version(s) support filters processing an image by tiles?
I have some of my filters which make use of tile processing to speed up the pixel by pixel processing.
At a first test of the newly released 2.9.6 it seems that none of those run.
If someone who is using already 2.9.x releases can double-check I'll appreciate.
Thanks.

(BTW another small concern about this release: it says that "add_layer" is deprecated and suggests "insert_layer", but the first one is executed the second one no(???))

Hi,

I use this script:

Hi All
Ive only been using Gimp for a few weeks so Im a relative noob.

I am trying to print to a networked printer managed centrally by Paper-Cut. When I try to print an .xcf file it gets put on hold awaiting authentication. There is no way to resume printing and authenticate. (Which is the usual process)
When exporting the same file to .png and printing there is no problem. It uses my prev' saved authentication credentials and it prints out fine.
Q1. Is it the file type and Paper Cut doesn't know what to do with it?
Q2. Is there any print resolution advantage in printing directly from Gimp instead of .png?


Cheers

Rob

I've discovered the capability that GIMP has for obtaining images directly from the scanner without creating intermediate files (i.e., File>Create>Scanner/Camera).  What I don't know but think I should is the format of the data be transferred from the scanner to GIMP.  I think the interface that is being used is called TWAIN.  Of course what really matters is the image quality being delivered by this mechanism.  For example, when scanning pictures that I want to edit, in GIMP, I've been avoiding the use of jpeg because of the lossy compression.  I'd opt for tiff if using intermediate files.  Also my scanner is capable of producing images in either 8bit or 16bit formats but when using the TWAIN interface I don't specify a file type.  I've noticed that I can select a 16bit quality on the scanner but I'm pretty sure that what I'm working on in GIMP is only 8bit even though there is never any indication of a format conversion which I think must be happening somewhere.  Is it the scanner or GIMP doing the conversion?  Or else the scanner is able to figure out that GIMP wants 8bit and does it without informing me about the discrepancy.  Is the data being transferred in a format equivalent to a file?  If so what type of file?  Or does the TWAIN specification dictate the format.
