Using Gimp 2.10.30 (32 bit) I was working on a 15,000 x 20,000  size image, and noticed that gimp was reporting the project size as 11.8 Gig (see attached).  Once I eventually exported the image... the final file size was only 135 MB.  But, I'm surprised that 32 bit gimp can count up that high?   What was actually going on behind the scenes allowing this to happen?




Additionally, this particular project involved my "quilting" together 10 fairly large tiles of a map, into a single image. This required SUBSTANTIAL moving, tilting, scaling, and redoing a large number of operations in order to get all the roadways to line up properly.

SO there is little doubt in my mind that I had a considerable amount of memory tied up, in the form  of "undo" operations.

Is there a good way to tell gimp to release "undo memory" during the course of a protracted multi stage project.

For example, once I had 6 of my 10 tiles edited and placed perfectly,  all the memory being held to save the "undo" operations up to that point, could be put to better use if released.

If that seems like an unusual ambition, consider that I came to this point the hard way.  The first time through the assembly of this quilt,  4 hours in and working on the 10th tile.....I did run out of memory....and the end result was not rewarding.  

So, this question is more or less a think-back to what I coulda/shoulda/woulda have done.

Hello All,

I was excited to see GIMP supports Scheme so I took a crack at generating some procedural camouflage.
Overall it was easy and I'm happy with my effect.
There seems to be one slight error and that is that my topmost layer seems to be drawn transparent if you use my default colors when running the script.
To run the script open a fresh blank image and then select the script.



My code is here:

The xcf image in question I'll attach.

If you disable all layers except for the first you'll see you can see the checkerboard showing through.

Hi, is it possible to convert a PNG into .cur and a set of PNGs into .ani using GIMP? I currently have SVG, can convert it into PNG to use as cursor files in Windows 10 and 11. Thanks.

Hi there,
I have a piece of artwork I've added to Gimp and am trying to scale to certain dimensions. I was my understanding that if you use the scale tool and insert either the new desired height and width of the drawing (and the scale is locked), and press 'scale', that it would automatically re-scale it to fit the dimensions, however, it doesn't seem to fit the specified dimensions exactly, with gaps showing on either the sides or top/bottom. 
Any idea how to get it to scale a drawing to a specific size?

Hi. New to 2.10 and gimp.
I have a problem, where my pencil will not draw at full color strengh - I have to draw the same spot 3-4 times to get black, green or any color. Have tried changing pencils and opacity is at 100%. Can't seem to figure it out.
Hope you have suggestions.

I'm am trying to understand how to add color to a black and white halftone image (ex. a vase of red roses- the vase and all roses are in black and white halftone...except the middle rose will have the rose buds colored red), I initially tried cutting the image (the middle rose only) I wanted to added color out using the free select tool.

I then copied the extracted color objected (rose) and went about turning the image into a black and white halftone image.

I then tried to paste the color rose onto the half tone portion of the image however whenever I add the rose to the halftone design the rose becomes black and white.

Is this the incorrect approach to this design or is it not possible to create halftone black and white with a single object(s) in color?

Hello,

1- Initially I trace some strokes on separate layers.
2- Then I merge these paths in a single layer, but the result that is obtained from the selection of this path does not match the created paths.
3- I would like to be able to get a selection close to what you can see in the illustration below this image (3):



Is there any way to achieve this with Gimp? 

I've tried the Join Strokes plugin but no success.

Thx!

Hello all,
I've just upgraded from version 2.10 (.10 as I recall) to 2.10.32 Flatpak on Linux Mint.  Whatever the previous .xx version was, I had an eyedropper in the toolbox' Foreground Color's Change Foreground Color dialog (same also with the background color) that was supposed to let me click on the eyedropper and click on any color on the screen. 

To get to the eyedropper in question, click on either the Foreground color or the Background color.  Up comes the appropriate Change Color dialog with a palette of colors to choose from, together with the HTML color code (hexadecimal 6-digit code representing RRGGBB).  The eyedropper has a pop-up explanation to "Click the eyedropper, then click any color on your screen to select that color."

I happen to have a Pencil tool selected.  I've opened the Change Foreground Color dialog, clicked on the eyedropper, then clicked on the white part of the U-Haul truck to select that color.  (I want the truck's branding to disappear from my photo of a camping activity, as it adds clutter behind the subjects of my photo.)  The Pencil drops a circle of pink where the eyedropper was to select the white shade.

Better that I exit from the Change Color dialog and use the Color Picker tool.  That works.

The same issue exists in the 2.10.32 version just installed.

Can anybody tell me how one uses the eyedropper in the Change Foreground Color dialog?  It is redundant in a way to the Color Picker tool, but it would be useful while in the Change Color dialogs if it worked!

Hi there, I keep getting a "unknown file type" message when trying to open a FITS file. Some files are from my camera and some are from the internet. Most are 12 bit or higher. Take care. EDIT: Actually, GIMP will not open any picture file, .jpg, .png, ect, has the same error message. Wonder if I need to re-install GIMP.
