I have an image with 5 placeholder texts, and I've written a python function (I just copy-paste it in the console and then call it as needed) to change those texts and automatically export the image with a custom name. It works great, but I was planning on using the same function without needing to open GIMP at all.
Is there a way to make my script autonomous from GIMP?

Good Morning, 

I REALLY need someones help. 

I am trying to use GIMP to change the opacity of a image down to very low. But have text within the image, which contains the original opacity.

I have attached an image of a website who've done exactly what i'm attempted to do. As you can see in the example, the text is bright and vivid, using the images original colours. However the rest of the image is creates the more opaque background. 

Any ideas on HOW THE HELL to do this??? haha!

Many thanks

Hello, I'm a teacher currently in online teaching mode because of current world events.

I thought since Gimp 2.10.8 comes preinstalled on our pupils computers I'd have them use it for art class. But many of them can't paint. Not using the mouse, nor the pencil that comes with the computer, nor by the touch screen.

Things I have tried:

Have them select all
Have them create a new layer
Check tool color, opacity, size and the actual brush
Check the dynamics settings
Reset tool settings
Restart


I had a pupil share screens with me so I could locate the issue but I could not find it, and it has not happened to me even though I'm on the same kind of computer as they are.

What I noticed when I looked at their screen was that when the left mouse button is pressed down the preview-ring showing where the tool is located gets stuck and will not move when the pupils then continue to move the mouse around.

Some pupils reported they can paint with the mousepad but not with the pencil for the computer.

Anyone have any ideas?

I'm a first time poster so please excuse me if this is already answered, I tried to find the answer here and elsewhere but no success yet.

Basically my problem is that I'd like to use my photos as Google Chromecast wallpapers, but many of them (100+) are in aspect ratios (and in many different resolutions) that are not quite 16:9, and in these cases Chromecast just pan & scans the photo. There's no other way to display the whole images than reprocessing them to 16:9, but I don't want to do this manually.

Is there a way to somehow automate this on GIMP?

The process, when done manually, is as follows:
  - Use calculator to multiply height of image by 1.7777.... (result = New Width)
  - Go to Layer > Canvas size, input New Width (width and height fields unbound)
  - Click "Center"
  - Fill with background color selected
  - Click "Resize"
  - Export as JPG with "_Wide" added to filename before the dot

Exporting & saving the resulting image doesn't have to be a part of the automation, but would surely be handy.

I know there's a scripting subsection here too, if a script is the way forward here sorry for posting in the wrong place -- I just don't know really anything about the scripts. I have written some Visual Basic macros though for Excel   

I'd be very grateful if someone could give me pointers! Any kind of method that would take away the manual calculation and canvas resizing would be terrific.

I have currently v. 2.10.10 on Windows 10.

Hi,

I have installed GIMP 2.10 for the first time on Linux Laptop. And I immediately made something wrong and the lower dock on the right dissappeared and the dock on the left it is showing on the right all the time.

Please how can I make the dock on the left again and bring back the one that dissappeared?

Thanks

In my next post I would like to upload a .xcf file and a one-page .pdf file. How do I do that? Is it done using the Attach procedure?

The .xcf file I mean to be downloadable, so that the reader can download it in order to experiment with the file in Gimp.

Can the .pdf file be attached as such or should it be zipped?

Or would some other method be preferable for sharing such files?

Hello again!

I have three plugins to share. They are about transformations of Gimp's paths. Nothing remarkable. They are the first step in my current project, and I paused my work to make them into plugins. My long-range aim is to try to make plugins that transform Gimp paths by certain more interesting (conformal) maps.

I know that there are already transformations to deform images. At least G'MIC has a long list. I have not tried those, but it is my guess that they transform images, not paths. But if I am wrong, and if they (or some other existing plugin) can be applied to paths, I hope that somebody tells me so that I shall not work in vain. The problem in transforming a path (for example by a Möbius transformation or such) is different from transforming an image since the input is control points of Bézier curves and the result must again be represented as Bézier curves. Hence, there needs to be an approximation.

Anyway, as a preliminary step I wrote the three plugins. These plugins deal with cases where no approximation is needed, so the results are exact.

Of each of the three plugins I shall soon make a special introductory post. My time is nowadays rather limited, and I think this will take perhaps a week. Here is a quick overview of the plugins:

1. Affine maps. Nothing new here, of course, since Gimp's own transformation tools do affine maps on paths. My plugin gives a different interface: not WYSIWYG, no moving of points on the screen with the mouse, nothing fancy. Very elementary, and the reason why I made the plugin is that I may need affine maps later in my project, and certainly I need similarity maps.

2. Transforming a line figure by a transformation constructed from a Bézier arc. This is new, to me at least. The path to be transformed is what I call a line figure: a path consisting of straight line segments (for example a lattice or a grid). The transformation is in a certain manner constructed from a user-supplied Bézier arc (a path with two anchors). A different arc will give a different transformation. This all I shall explain in detail in a later post.

A3. Deforming a polyline, segment by segment, with a transformation as in number 2. (Actually I call the deforming "curling".) Number 3 is just a variation of number 2.

Of the three I expect number 2 to be the only one interesting. (But then when I ever try to guess what people will find interesting, I go astray. Perhaps I should only say that to me number 2 is the only interesting.) What I myself have in mind is that the code of this plugin will serve as the body where I shall add an approximation algorithm (don't know yet how). Number 1 does nothing new, and number 3 is ..., well, I doubt if it is worth publishing after all, and perhaps it will be removed in later versions.

To get the plugins, go to

http://kmarkku.arkku.net/Path_transforma...aster.html

and scroll down to the bottom. There is a Download button, and it gives you a .zip file containing one file path_transformations.py. Put the .py file in your Gimp's plug-ins folder and restart Gimp. That registers three plugins in your Gimp. They can be invoked in Gimp's Paths tab: right-click the path you want to transform, and at the bottom of the opening window follow

Tools > Transformations > ...

and you will see three plugins to choose from. You can try them right away, but I am going to make explanatory posts of each soon. For the affine maps it will appear today. The rest will follow in a week.

I wonder if there exist a plugin/script that draw an arrow with label on a path ? (for gimp 2.10.18)

Thank you in advance

I have had a file sent to me, but I am having problems opening it on Gimp. It was originally a PSD file, which I put through a PSD convertor and I saved it as a PNG file. But when I open it, all I get is the front picture, there are no individual files in it? Is there a way around this, or does Gimp have problems reading this sort of file? Thanks.
