I recently installed Gimp 3.0.0-RC1 using the windows installer (on Win 11 - 64-Bit).

I am new to plug-in development, having only written one plug-in for Gimp 2.10.38 just last week.  The 2.10 plug in works as I expect it to.  In learning plug-in development, I discovered 3.0.0-RC1 and decided to install it and convert my plug-in to work with 3.0.  To start, I attempted to create a simple, "Hello, World!" plug-in.  Currently I have:

Gimp.main(AnimateDrawableOffsets.__gtype__, sys.argv)

OK.....so, after re-reading the error message, I noticed it also included the line, " missing 1 required positional argument: 'run_data'"...removing this parameter from the definition for the run function allows the plug-in to operate and I can now see the "Hello, World!" message in the error console.....

I do not know what this parameter is for, or how removing it will affect the plug-in development.  For now, I will keep researching what this parameter is used for and how it becomes populated with run_data.

Hi,

I'm looking for volunteer(s) to run this test plug-in. The plug-in creates an image and selects a square polygon at the topleft of the image.

At least that what's it's supposed to do. However, the plug-in will crash while failing to select the polygon. The failure appears to be in the procedure: 'gimp-image-select-polygon'.

How do I crop an image to 1280 x 720?
Thank you for any information

Hi folks! I was creating a gif of a product by taking separate gifs and stills of different product views and then combining them into one gif using GIMP (manipulating these as separate layers). But four of the gifs (taken with the program LICEcap) would have really messed up colors when I combined it with the others. I attached a .png of a still from one of those gifs.

For these four gifs, I first grabbed the gif using LICEcap, then I uploaded it to Canva to put the gif on a static background, and then I took that and loaded it into GIMP with the intention of combining each with other static images/gifs.

I was able to solve this by doubling up the "background" layer on the very first gif this was happening with; literally just making a copy of it. The other three I have not been able to resolve. I played around with making/removing the "background" layer of the gif as an alpha channel (though I don't fully understand this concept), but this did nothing. 

It's weird to me, because these gifs look totally normal on their own, and when I edit them on their own. It's only when I brought them into the final gif document to combine them that they got weird. 

I ended up using an online program (ezgif.com) to fix the issue, because I was on a time crunch. When I loaded the gifs that were problematic in GIMP onto ezgif, they did not display weirdly. However, going forward I want to use GIMP!

Any help and insights is greatly appreciated!

Hello my favorite Admins/moderators

We can do arrow to the right by doing 2 angle brackets to the right > > = ➤ , but we cannot do it the other side <<
For reference I wanted to do it on this post ➤ https://www.gimp-forum.net/Thread-Digika...8#pid40998 but nope no can do

Thanks for reading, and have a great day.

Has Gimp changed the way layers work in 2.10.38? If so, can you point me to instructions? I've looked for hours and haven't seen anything that describes the behavior of layers I'm seeing. When a New Layer is (apparently) integrated with an existing layer how do I separate them?
 Also, when I right click on an image layer all I see is New View, Raise View and Delete View. What happened to the right click menu option?
I'm assuming operator error could play a part but I don't know what it could be.
Thanks for your attention.

Hi All,

Fedora 41
gimp-3.0.0~RC1-2.fc41.x86_64

Since upgrading to Fedora 41 from 39, Gimp upgraded to 3.0rc1, I lost my arrows.

I have "arrow_V3.scm" from http://programmer97.byethost10.com/Files/arrow.zip   copies into "/usr/share/gimp/3.0/scripts".  When I select
-->Tools --> Arrow --> Arrow --> Okay, I get the following error:

Execution error for 'Arrow': Error eval: unbound variable gimp-image-get-selected-vectors

"arrow.scm" does not work either

How do I fix this?

Many thanks,
-T

Hello,
 
I am a new user of Gimp (2.10.38), but I have used several drawing programs including Sketchbook Pro. I replaced a failing 10-year-old MS Surface Pro (Windows 10) that I use with the stylus it came with. The stylus on the Surface Pro works as expected with Gimp, as well as all other programs that use a stylus.
 
The new computer is a Lenovo Yoga 9i 2-in-1 (Windows 11) that came with a Lenovo Slim Pen stylus (compatible with WGP, MPP2.0, AES2.0, and AES1.0 protocols). The stylus works perfectly with all other programs (apps) that I have tried so far, including Sketchbook Pro. It is not working with Gimp 2.10.38.
 
I have searched, viewed or read dozens of suggestions for making a stylus work with Gimp in the forums, YouTube, and other internet findings and have tried many of them. What I have been able to do so far is to create dots at the beginning of each attempted stroke of a brush (or pencil or pen). The dots are the same size no matter how much pressure I use to make the stroke, but at one point the dot sized were proportional to the pressure. The screenshot shows examples of four attempted strokes of the brush, and below those marks are strokes made using the mouse.
 
Any suggestions about how to get the stylus to work will be appreciated. Thanks!
 
Mike
