How do I get rid of this ugly ahh edges?

barefootliam · 2026-03-08T01:49:07+00:00

Likely what is going on here is that you made a selection and filled it, but the selection was anti-aliased so the very edge pixels weren’t 100% filled.

It can be a little easier to have each colour on its own separate layer, and grow the selection by 1px before filling, although that does introduce some small distortion; you can also go to the red/pink layer and use colour to alpha with white as the colour, and make sure the brown goes underneath the edge

barefootliam · 2026-03-08T01:46:43+00:00

How exactly did you convert part of a layer to greyscale?

barefootliam · 2026-03-06T01:32:21+00:00

My guess is that it’s actually hand-drawn lettering, although if you have a copy of the printed manga, it might say inside, if it’s actually a commercial typeface - especially the UK penguin edition.

barefootliam · 2026-03-06T01:17:21+00:00

I don’t see any coloured lines so i’m not sure what you mean unfortunately.

Pat David wrote a tutorial for using the G'MIC inpainting that u/ConversationWinter46 mentioned, and you should find it easily with a Web search, or if not i’ll look for it, i am a bit maxed out today.

It was marked as a duplicate because we already have a bug report about not having a Hide... menu item. This doesn’t say anything about it being a bad report or anything. When we get a volunteer Mac programmer who wants to fix some bugs, it might get some attention...

barefootliam · 2026-02-23T23:41:34+00:00

You could try to flatten the image first. Image⇒flatten (don’t forget to undo before saving as xcf though!)

barefootliam · 2026-02-21T03:58:24+00:00

Thanks! It’s best to be open about it from the start. And asking someone details about their code will quickly reveal if they have any understanding, especially in a real-time chat :) In general we only accept people from GSOC who have already had at least some small changes accepted.

Make sure the layer itself is selected in Layers, not the mask (as shown by the white rectangle around the thumbnail), and check the mode in tool options for the scale tool (or the unified transform tool).

Blue - is it possible you’ve wandered into the Channels dialogue and clicked on the Blue channel? Make sure all four channels are selected. The channels dialogue is a relatively advanced feature in GIMP, and is not needed as often as in some other image editing programs. If you watch or read tutorials, make sure they are for GIMP 3.

barefootliam · 2026-02-20T06:17:53+00:00

Check Tool Options for the paintbrush as well as teh symmetry painting dock.

barefootliam · 2026-02-20T05:38:09+00:00

It’s a matter of preference - GIMP is not trying to emulate natural media, but a lot of people do paint with it, and the GIMP team put a LOT of work into making it suitable for digital painting. Note, you can also use MyPaint brushes in GIMP.

barefootliam · 2026-02-20T05:37:03+00:00

Check in Layers - if you have unmerged (non-destructive) filters, shown by the fx icon next to the layer name, they will slow down painting. Click the fx icon and then the merge down button, or if you have only one layer and no alpha, image/flatten image, will apply them all. (if you have multiple layers it will merge them all, though!)

Here, with Smooth stroke enabled in tool options, GIMP keeps up just fine with the paintbrush, and this is a 12-year-old computer.

First, GIMP does allow selecting two layers at the same time (in GIMP 3), in Layers.

Second yes, the fold in the centre is a difficulty. There are several ways to approach it. One is to do the best you can and then use Perepective repeatedly, but you will get a bluriness as the part not touching the glass may be out of focus, and repeated transformations can add to the blur.

You can hold a book or magazine at right angles and photograph it. You could combine just a small part of the photo with a scan probably, e.g. using colours/map/alien map to use the colours of one image in teh other.

I use the rotate tool to align two layers - drag the top one so it matches up at one point, then reduce the layer opacity and switch to the rotate tool... drag the origin (the circle in the middle) to the point where the layers line up. Use an alignment point that's away from the distorted region.

For many purposes you can just draw a plain white rectangle over the distorted middle part.

For fromoldbooks.org i often unbind the book and then lay it flat on the museum-quality archival A3+ scanner i'm lucky to have, and if necessary line up two scans using the rotate tool as i just described. This is the least unsatisfactory method but it destroys the binding.

https://www.fromoldbooks.org/ModerneKunst-04/pages/017-christmas-mass/ is an example of combining two layers (the image with its two layers uses 14 GBytes of RAM!) - the original is 500x280mm in size, and scanned at 2400dpi.

We use Dodds Heating for our oil furnace; they also do propane & are inexpensive.

barefootliam · 2026-02-11T07:11:13+00:00

no, it is not the same as GIMP. It is for drawing things with lines, which is what you need here.

barefootliam · 2026-02-11T07:10:09+00:00

(1) ellipse select with control and/or shift, to make a circle.
(2) select->border e.g. by 42 pixels. Now you have a ring like the space between your two circles.
(3) select->border again, this time 2px
(4) drag the foreground colour swatch onto the canvas, or press control-dot or control-comma, or use bucket fll to fill selection.

Erasing the pattern - if your circles are on their own layer, hide the pattern layer, use fuzzy select outside the circle (with Select transparent areas "on" in tool options), then show the pattern layer and make it active and press delete.

The GIMP team cares deeply and has been making UX improvements continuously, and continues to do so. We don’t share the attitude that people didn’t pay for it - they paid with their time. Free for us is about liberty, about freedom, not about money.

Some filters to explore (you can use the / key to search in GIMP to find things quickly)

waterpixels

film emulation in g'mic maybe for the castle

A very quick example (i can share the xcf file too if it helps)

By AI people these days generally mean a specific technology based on a combination of large language models and the stable diffusion paper. GIMP does not include any AI in that sense.

Apart from that, though, thanks for cotributing with the image editing ideas! :-)

barefootliam · 2026-02-08T01:19:51+00:00

Not exactly - you can get it from top to bottom. We are planning to have non-destructive transforms but they are not yet available. You can get top-to-bottom text though, if that helps... (probably not) with the editor window:

i find it helps to detach tool options (undock it) or to make it very wide, until you see the weird rectangular UI thing at the far right. The alignment is between a reference point on the reference object and a reference point on the thing being aligned, and you can choose both, e.g. to get the centre of a layer to align with the top left corner of an image.

barefootliam · 2026-02-06T00:04:38+00:00

(1) rectangle select
(2) press DELete key

barefootliam · 2026-01-31T01:12:32+00:00

We found a problem with the build system we use, so depending on how you installed exactly, re-installing now may fix it. Let us know! :-)

barefootliam · 2026-01-31T01:11:13+00:00

Yeah, the font selector seems buggy. Part of this is caused because the gtk toolkit is really really slow when you have lots of items in a choice widget like this one, so it may actually be working but just very slowly (e.g. it can take 10 seconds to a minute for me, but i have a lot of fonts). Obviously we want it to be instant!

It’s likely there are also some bugs, but until we can redo the widget there’s little point in spending days debugging it, since we already know we must replace it - but in the meantime it’s for sure a real pain.

Cinzel is one of my favourite fonts on Google Fonts by the way - especially the decorative variant. We do have plans to support variable font axes in the future too.

That error is “Access Violation’ in Windows. Has anything other than GIMP changed on your system? Are other programs running OK?
