Hi,

I want to reduce the hue range of an image by dividing all hue-values by a variable value without touching the saturation- and lightness-values (any more sophisticated projection of the hue-range would also be very interesting).

I am looking for an automatic process that could for example turn the 1st attached image (temp_full_hue.png) into the 2nd attached image (temp_half_hue.png).

Ofc it wouldn't matter where the resulting hue starts, since I'd be able to shift it to wherever I want.

Kind regards

I have an image that I want to extend to the right. Most of the right border is a vaguely orange-red color, lighter near the top of the image, darker near the bottom.

I want to make that image larger by extending that border to the right. If all of that border followed that pattern, I would just copy it piecemeal and paste it next to the existing border. But there are a few places where bits of furniture etc. touch the right border, and extending those in a straight line would look weird.

So far, I have copied pieces of that right border using a rectangular selection tool at a 400% zoom (with the grid spacing set to 1, this makes each pixel visible to the naked eye) and repeatedly pasted them to the right until I reach the right edge of the (expanded) image.

But where other things touch the right border of the original image, there are breaks in that nice smooth flow from light orange to dark orange, making a hard visual boundary where they meet.

I want to "erase" that boundary, making the transition gradual across the entire right area.

I thought of applying a few hundered iterations of a "relaxation" algorithm: color(x,y) = (color(x+1, y+1) + color(x+1,y-1) + color(x-1,y-1) + color(x-1,y+1))/4 , but I thought it would be better to learn how to do this in GIMP, if I can.

Suggestions?

See the attached image for what I've managed to do so far.

Btw, the messy area in the top center is the result of my trying to erase boundaries with the smudge tool. It didn't work as well as I'd hoped.

What is the best way to minimize screen space occupied by tools / icons / command windows / etc.?

When working on my laptop with its puny 13" screen I want to see as much of the image as possible. Which means hiding various icon/command/tools windows. What is the best way to do this.  Note: I do not want to get rid of essentials such as the menu and the status tools. How?

During a GIMP upgrade;... are my settings, added scripts, & and added paths kept?

[currently Win7 Pro 64bit, GIMP c 2.10.14]
thanks!

Hi, 

I am having trouble making the Wheel/Rotation work for dinamic brush settings. 
I can see the tilt is recognized well but using the air brush pen, the one that has the wheel, there are no changes when for example I wish to change the brush size with wheel/Rotation. 
The Wheel/Rotation ( wheel on the air brush pen and rotation on the art pen ) are rocognized in other apps like photoshop.

Is there another option that needs to be enabled for this to work ?

Hi, I'm new here and just installed Gimp 2.10.20. I used PS for years...

I like what i see and want to transfer to Gimp. But I ran into a problem now: How can I use the color picker outside of the Gimp window, eg to pick an  original color from my web browser to get it as a foreground color or its hexcode? I couldn't solve the problem with YT tutorials. So I try, if maybe someone in this forum hopefully knows an answer. 

Ok, I could import a screenshot and use the picker inside Gimp, but I need this so often, that I think maybe there's a trick cos in PS I just moved the eyedropper to an open browser and I had exactly the color of the pixel under the cursor, no matter where ever I clicked. If I try this in Gimp, the picker turns into a standard windows picker, as soon as it leaves the Gimp area, what normally makes sense, but not, if I need a color from my desktop window. Sorry for still being a noob, but maybe someone is so nice to help me.  

Thanks, Finn

On my Debian 10 system, Gimp's memory usage builds up as I open/close files and never goes down until I quit Gimp, leading it to fill the memory and use the swap even though I have 64GB of RAM and each xcf file is less than 1GB (and I only open one at a time).

Is there a setting I can change to make Gimp free memory when an image gets closed?

I wanted to post a thread in Gimp 2.10 section, but I don't see an option for posting a new thread there.

I would like to create a layer from the below image that goes from full opacity in the centre of the clock to transparent at a certain radius. I guess this is a sort of "radial transparency fade selection". So I would like a circular image which is 100% opaque in the centre, and completely transparent around the cirumference.

How would I go about doing this in GIMP? I've tried using the Gradient tool on a white transparency mask, a FG to Transparent gradient but I am getting absolutely nowhere.

Can somebody please help me or point me to a good tutorial that does this?

The paint bucket in Gimp 2.10.20 is not adding color correctly. As you can see from the attachment, colors in two of the three rectangles are faded. The bright gold one is pasted in from elsewhere and the paintbrush strokes do properly show color. Same thing with the blue. For whatever it may be worth, I'm running GIMP on a fully updated version of Win 10.

Any idea what might be causing this and how to fix it? The color setting is exactly the same for the brush strokes and corresponding box.

Thanks for you help.
