I've been using the same format for editing/making art in GIMP forever. 4500 x 5400 pixels, 300 PPI.

Recently I saved and closed a project, and upon reopening it, my brush lines are now jagged and pixelated. I can draw a new line with same brush settings and the lines come out smooth and fine. I am 100% positive my image was still smooth and fine when I saved the .xcf fie and closed GIMP. Something happened and I can't figure it out for the life of me.

Any help with this would be greatly appreciated, as I am essentially losing 8-10 hours of work here.
-Thanks

Hello, I'm a new Gimp-User and I hope I can find some help for my problem here. 
I am trying to apply a default gradient to a new image, but it doesn't work.
Here is the result of Abstract 2, but it's the same issue with any other default gradient.

The problem still persists after the update.
Thank you for any suggestions,

Have the colours of the lettering on the main interface changed recently?
I use a dark theme and had no trouble  seeing them before - all of a sudden the writing has gone black on a dark grey theme!?
I know I could have made the change - I was messing around in preferences earlier today. I do not recall going into themes though. Is there anywhere else I could have changed it? How can I change it back to a lighter colour?

Hi everyone :

 I just discovered a limitation of GIMP  2.10.   Whenever I import a .jpg file (either as a background or as a LAYER), the SHADOW  tool won't work.  But.....when I use the TEXT tool,  I am able to use the SHADOW tool.  One reason is....that the TEXT tool is an internal tool. Whereas, importing a .jpg file works on the basis of being external.

Hi everyone :
 
    I'm still learning GIMP.  I'm  trying to learning how to add SHADOWS to text and objects.
 I open GIMP>OPEN AS LAYER> select .jpg file.  Then I use the SCALE tool to "enlarge" the file.  After that, I click on ADD ALPHA CHANNEL. Then select FUZZY tool. After that,  I select the box next to the one that shows the object. I use that one to do the "erasing" of the bacground. Sometimes the DROP SHADOW/LONG SHADOW options are greyed out. But if I select the box (in LAYERS) showing the object, the background won't erase.  The other problem is....if I DO get the shadows to work.....it's cutoff ( I used the LAYER BOUNDARY SIZE / LAYER TO IMAGE SIZE).
Advice ?

I have layers with single color layers as I really like these colors.

I want to make a palette from these colors.

I've followed the instructions at https://docs.gimp.org/en/gimp-palette-dialog.html#gimp-palette-new

I made sure all of the color layers were visible

I selected ALL

Import Palette

Chose

• Sample merged: When this option is checked, colors are picked from all visible layers. If unchecked, pixels are picked from the active layer only, even though not visible.
  
• Selected pixels only: As the name says, pixels are picked from the selected area only, in the active layer or all visible layers according to the status of the previous option.

I have 7 video frames (saved as PNG) of a lightening strike who's main 'vein' persists over most of the frames but is also producing 'tendrils' that are different in each frame.
I want to make a single image that includes all parts of that strike over time.

I have imported each image in GIMP as a separate layer.
I have tried 'Merge Visible Layers', that basically gives me just the first image.
I have tried setting each image to 50% Opacity and then each image Mode to 'Merge' - which is the closest I can currently get to the desired end-point, unfortunately the grey in the clouds where the image does NOT include the 'tendril' tends to erase that from the image where that tendril IS present.

I have experimented with Add Subtract and Multiply but they all badly effect the overall background image.

I have no doubt that this has been done before, but Google and this forum search does not result in anything awesome.

Attached are a couple of the (reduced to 20%) frames that the effect is visible in.

Hail all:

So, AI driven sites (and even few releases of the software) are becoming mainstream.

Does this translate soon to Gimp as well?
I mean, it would be neat, to see a Gimp with AI support, for things like cleaning up an old picture, or to improve the quality of a less great picture, things like that.

Or, for others, to "generate art from scratch", not that so my thing, but hey, to each his own.

"Simple" support tools to "auto-improve" pictures is good for me, based on AI-algorithms.

Thank you:

Hi,

This question came out of the following posts:

Does pdb.gimp_drawable_curves_spline want the spline control points to be in the range 0.0 - 1.0, or 0 - 255, or can it cope with either?

As far as I can make out, the deprecated pdb.gimp_curves_spline takes 0 - 255 and calls the C function curves_spline_invoker() that divides each point by 255. The replacement pdb.gimp_drawable_curves_spline calls drawable_curves_spline_invoker() that looks very similar but without the divide.

In summary these both work for me:
pdb.gimp_curves_spline(layer_copy, HISTOGRAM_VALUE, 6, [0, 0, 157, 110, 255, 255])
pdb.gimp_drawable_curves_spline(layer_copy, HISTOGRAM_VALUE, 6, [0.0, 0.0, 0.615, 0.431, 1.0, 1.0])

This doesn't work for me, as it makes the layer all black, but works for David and Issabella:
pdb.gimp_drawable_curves_spline(layer_copy, HISTOGRAM_VALUE, 6, [0, 0, 157, 110, 255, 255])

Should the latter work and why would it work for them and not me?

Many thanks for any help.
