Hello, I'm thinking of switching back to Gimp 2.8 like I did on Windows 7 and it worked like a charm, but the new Gimp 2.10 I got on Linux Mint Cinnamon 22.1 Software Manager seems to have some functionalities like indexed mode I was really use to completely broken.

Is there a way I can download Gimp 2.8 on Linux Mint? I didn't see it in the Software Manager there was only 2.10 and I assume an even newer version..
I do have the installer for Gimp 2.8 I used on Windows 7 which probably can be run with Wine, but I would prefer not to do that because from my experience it seems everything that's run with Wine on Linux seems a lot laggier and choppier than it was on Windows 7 which is not good for when I want to draw...

If there's an AppImage of Gimp 2.8 I would prefer that because those are convenient and have everything they need to run, I looked on the official Gimp site and it said it had a download for 2.8, but it would always redirect me to Gimp 2.10 on the Software Manager so I assume it's not on the official site.

I really need help this is really stressing and frustrating me.

I have been on Windows 7 for the longest time and using Gimp 2.8 with no hassle and it was very easy and comfortable, I now recently "upgraded" to Linux Mint Cinnamon 22.1 and installed Gimp 2.10.36 from the Software Manager on it.

Now I like drawing sprite art on a transparent background and when it's done I index the sprite art because it makes it to a very small filesize which makes me happy, on Windows 7 Gimp 2.8 this was super easy I would just select the indexed mode and apply it and bam it would index the image with no issue at all.


Now on Linux Mint Cinnamon 22.1 and Gimp 2.10 (I don't know if Linux is causing this problem or Gimp is) when I try to index an image with transparency it completely messes up the saved image!

This is just an example of an indexed image I happen to have it's of a Charizard sprite, as you can see the original indexed image from Gimp 2.8 on Win7 is completely fine and has its transparency and is a super low filesize.

Now when I open that image in Gimp 2.10 and do absolutely no changes except export it as a new image look at what happens to it!

Now here's the weird thing, if I add a solid color background (like white for example) to the original image then export it the colors don't get corrupted, but the filesize is still massive! [attachment=13875]
I'm at a loss for what to do.. did gimp 2.10 just completely break indexed mode or maybe it's the version of gimp on the Linux Mint Software Manager?

Somebody please help

Hi! Im having some issues when using the Desaturate>color to gray as an FX. If i note merge and leave it as FX, it dont show accurately the edition. Plus, gimp become unstable, and even it delet some portions of the canvas until i shut it and restart. No problem with other fx, at least im aware. Im on windows 10. I will try to see if this happen in linux.

Is it possible in GIMP to create variants (versions) of the project? Sometimes it is not convenient to have several files for one project.

I am fairly new and basic to GIMP, I have used SVG files in the past and cut out vinly signs and graphics with GIMP.

I have a PNG file that I paid for from a digital artist. I uploaded the file using upload as layers and changed the embedded sRGB IEC61966-2.1 to the one GIMP suggested. I selected all and added the alpha channel. From here, I thought I would be able to size the image, duplicate and crop the two new images, save and export them to my sublimation printer.

Behind the image is a transparent layer and when I move the main image- it only moves within the transparent layer. When I try to delete the checkered layer- the main image deletes.
   
   

I was able to crop the image to selection, as shown but you can see the layer still and my image will "disappear" if I move it off the page.
   

Any help would be greatly appreciated, as I have 30 more of these images to print. If you need any more info, just let me know.

Thanks, Alli

How do I keystone (alter perspective) on a batch of images?

I have a number of images to which I need to apply the same perspective change so as to make them appear correct when projected onto a screen where the projector is not square on.

Thank you

Using GIMP 2.8.2 on a Mac with OS 10.14.6
Would appreciate step-by-step instructions as I am a bit of a newbie to Gimp.

Hi! Using Gimp keyboard shortcuts really make things faster. I recently installed Lubuntu and Gimp. Nice! But first thing i noted was that the usual "ctrl+alt+mouse scrollwheel" that increase and decrease the size of the brush, was assigned to the system virtual desktops. Bad! I guess i can make changes in Lubuntu of in Gimp. I wonder how you manage this issue? Would be nice to be consistent across different systems, so, when you open Gimp you forget where you are working.
Thanks

Hi.Is not a bug, but i believe an error in the distribution of text in the "Mode" selection of layers. It happens in windows as well as in Linux. While there is plenty of room to show all the modes at once, you need to scroll to see them, meanwhile the upper space is empty. Here an screenshot:
   

Hi all ! 

With Gimp, the most part of time I works on photos to simply add extra layers and export the result (maps, explanations, mechanisms, and so).

In this case I do not alter the original and keep it.

Recently I realized the most part of my XCF projects take more than 20MB per file vs the originals which take 2MB max.

After digging I understood the problem : projects keep the original raw uncompressed photo on a layer which is a waste of storage as I can include again the original.

In definitive I want to keep the original photo, the exported one and all that allowed to obtain the exported result.

I imagined an external batch process to open the targeted files, remove the usefulness layer, archive the original with the lighted project.

I discovered script-fu language (LISP scheme) and followed tutorial script-fu and experimented it with success.

But I did not found a way to achieve this : get the uncompressed layer size

I found the following procedures which are not "size related" :
- gimp-image-get-layer-by-name
- gimp-image-get-layer-by-tattoo

Is it possible to do this with script-fu ? Is it possible in another way ?

Extra question, is there a way to attach a file to a XCF project (I suppose no) like we usually do it with the email attachments method ? I hoped this could be achieved with an add-on ...


Thank you in advance for the time you will spend to me .
