I have something like the smiley list we have here, but a PNG with transparent background. ie, other than the icons ( here smilies ) everything else is transparent. Is there any method to extract these icons (around 6 ) with minimal steps instead of cropping them out one by one ? Thanks

A new plugin. My try on simplifying paths. If Gimp already has a tool for that job, I hope somebody tells me.

The problem is hard, and all I can say is that mostly the plugin works all right though sometimes its decisions seem strange. Anyway, this is the first published version, and we can think the plugin to be still just experimental, so there is room for improvements. To get the plugin, go to

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

scroll to the bottom, and click the download button. You get a zip file. Unzip it and place the one file it contains (simplify_path.py) in your user's plug-ins folder. Then (re)start Gimp. To use the plugin: in the Paths tab, right-click the path you want to simplify and follow the links Tools > Modify path > Simplify.

The plugin takes a path and tries to diminish the number of anchors, doing some smoothing but hopefully not too much. An example: On the left you see a path and on the right its anchors:

   

With default input values the plugin did the following: Below, on the left you see the original path (blue) and the simplified version (red) on top of each other. It may be difficult to see from that picture but there are small differences: many small bends were smoothed out. On the right you see the anchors of the simplified path.

   

The GUI looks as follows:

   

I hope the meanings of the inputs are clear enough.

Of the inputs the last one (about selection) may be the most important in practice. It enables the user to restrict the effect to some subset of the anchors. I shall give examples in another post.

The plugin is based on a neat mathematical idea (I think), but unfortunately, when one starts to implement a neat idea, it usually happens that soon one is in the middle of a mess. The plugin is full of my own ad hoc solutions to various problems. Please report if you find it doing something too odd.

This is the Pixelise tool shown in the documentation for 2.10 here: gimp 2.10 pixelise tool help

But I can't find this clipping option for this tool in gimp 2.10 for windows 10 x64 or 2.99 for win10 x64.

Am I missing something? Does the documentation show some features that don't exist yet? Is this only available on different platforms?

It looks really ugly having semi-pixels at the edges of the selection.

Anyone knows where to find this script : https://patdavid.net/2013/04/getting-aro...e-channel/
The link that is mentioned give error 404, script not available.
If someone find a working link, thanks in advance.

Hello,

I recent created a very complex selection. Then I saved the selection to channel. My selection then disappeared. I don't know how to get it back.

I assumed that this is my saved selection:

   

But I'm not sure what to do to load the selection into the image. Right-clicking on the selection gives me this context menu:

   

The most obvious item is "Channel to Selection" but that did nothing.

How do I get my selection back? Thanks.

Is there a way to set the aspect ratio default in the set image canvas size? Everywhere I read says that it should default to linked. Mine does not.

Also, if I reopen the dialog box again after clicking resize, it does not retain the linked status.

I don't know if it's something I did without realizing it or something else, but every time I try to copy an entire image and paste it to the transparent background that I have waiting in another tab, the image is really closely cropped and I can't scale the image without it looking stretched anymore. I use GIMP to make thumbnails for YouTube. I don't really explore much in the software, just sticking to the things that I'm familiar with.

If it helps, my OS is Windows 10, 64-bit.

Also, here's a screenshot of what I mean:

   

I'd like to cut a face of someone and paste onto another, they have different skin colors
of course. After selecting and cutting the face, what is the next step to do? 
Would you please highlight me the key steps I'll probably need?

I am not sure what is wrong. Is there a fix for this ? I was using @rich2005 's the G'MIC plugin. I just removed that to check but this preview error exists with the default AppImage with Plugins version : GIMP_AppImage-git-2.10.25-20210408-withplugins-x86_64

   

Hi, I have seen some Apple emojis which is face to emojis. I wonder whether there is any plugin or feature that we can use to convert a Photo into a not real-life face.



If I can get anything close enough, it will be ok to put some effort and make it look like this. Thanks.
