What is an appimage?
These are linux applications  assembled into single packages. The Gimp appimage for example, contains about 9000 files and Inkscape about 5000. These are big applications, there are small ones as well.*

Why use an appimage?
- Use an application infrequently, and consider it not worth the disk space as a regular installation. For example, Write very few letters / reports these days?  Use a LibreOffice appimage, stored on a 'data' partition.
- There is a more recent version of the application available as an appimage than the version provided by the linux distro. Some versions of linux, such as Debian, are very conservative and application versions are 'frozen'.
- Use different versions of the same application. For example, a regular Gimp 2.8 installation plus  a Gimp 2.10 appimage.
- As a try-out. Run the appimage. Like it - keep it. Do not like it - delete it. All gone, no hunting round for those dependencies apt-get installed. 

How to run an appimage?
Obviously download one first. Make the file executable. Depending on linux distribution, a double click on the file using the file manager will work.  Otherwise open a terminal where the appimage is located and run with a dot-slash ($ ./the-file-name.appimage)  Remember, the tab key auto-completes those long file names.
Depending on the appimage, a desktop file for the menu structure is added, but not always. Make one if required.

How does an appimage work?
A little like a virtual CD. The files are un-packed to a folder in root /tmp and work from there. When the application is closed, the folder is deleted. Sometimes small files remain, clean out the /tmp folder occasionally.

Does an appimage always work?  
No. An appimage is rarely completely self-contained, it can depend on system files. An appimage assembled in Debian, probably will not work with Fedora and definitely will not work with that 2003 Slackware installation.

I don't know any other place to ask about this. I downloaded Inkscape 1.0 as soon as I saw it was available. I skipped snap due to earlier experience and downloaded the App Image. I used" chmod u+x and the double clicked the app image. Everything worked fine. I could use 1.0 now. Very happy.

Now I have to come back and double click the App Image every time I need to use 1.0. There is no entry in Kubuntu 20.04 graphics menu, neither are there any files in " .config " related to 1.0.

I am quite ok with clicking the App Image every time. But it would nice if there was an icon to click on in menu or desktop. Just for the ease of use case.

Any help will be great.

Hello everyone, I hope you are fine and staying safe!

I'm still learning how to write script-fu script and  before I ask the question, I will like to thank all the experienced coder that are been helping me through out this learning process.

Hello.

I am new to GIMP and have been learning from trial and error as well as youtube tutorials.

One thing I cannot figure out is how to export a PDF that shows both landscape and portrait in on PDF file.

I am creating an A5 leaflet, so this is three layer groups, the front page, the middle pages, and the back page.

The front and back pages are in A5 size and the middle pages are in A4 size in landscape.

The issue is that when I export this into a PDF, even though I have left the transparent background in the front and back page to fit in the middle pages when exported, a white border on the left and right-hand side appears.

Does anyone know how to get this looking like a completed document without the white borders?

Thanks in advance

My way of saying "THANK YOU!" for your numerous contributions to GIMP Paths!


   

Hello my friends,

currently i've got a vintage Bamboo one S

doing it's job on Gimp with Xubuntu as OS
it's pretty beat up from use, and i'm looking for a succesor,

what would be a nice upgrade?

i'm kinda wow'd by the high prices,
and if there is a "B" class brand who does the same as my old Wacom that would be great...

the use of my wacom is without any extra stuff installed, just using it as main "mouse" and edit tool in Gimp

i've plugged it in and it worked... no need for fancy stuff yet, but due the small size it's kinda *bleep* for really small stuff

does the size also increase the ease of use when going bigger? like if i have to do small stuff  i've got to force my hand to work
if i'm going as big as possible does the tiny stuff become easier due just workspace?

Greetings,

I am very new to Gimp and really enjoy the functions that I am able to use but i have a small project that I don't even know how to begin and would really appreciate some help with please. 

I have a PNG image of a white bus that I need to paint some graphics on. Basically I need some orange stripes diagonally on the bus. I would like the stripes to be solid and evenly spaced diagonally on the body work and transparent over the windows and of course it must look like a paint job on the bus. 

Can anyone help me get started as I don't even know what functions I need to use and Googling and YouTubing isn't giving me the answers i want because i don't know what to search for. 

 Please see the blank bus attached and a basic idea (painted bus sample)  of what i am aiming to achieve. 

Thank you in advance.

Danny

Hi. Sorry for the generic title but I couldn't explain the problem I'm facing in a few words.

I'm facing this weird problem: I start with an image (a hand drawn picture made with Sketchbook, exported in photoshop format and imported in Gimp 2.10.18) that only contains a layer with semi-transparent black drawings, and a background white layer. Gimp imports it correctly, or at least everything looks good. If I hide the white layer and I export only the black-and-transparent layer into PNG, and then I open the exported image I have this behaviour: the image look the same, but when I add again a white background layer, the image blends differently with it, it looks washy, with less contrast and with lighter blacks. I attach an example to illustrate the behaviour.

As you can see in the picture below, the exported PNG looks the same until I add a background again.

Does anyone knows what's happening here?

How do I determine all colors in a photo?

     Look at the attachment.

This is what happens in GIMP when I try to draw. At the beginning there's a slight discoloration using the pencil tool. How do I disable this?
