eternityforest•6mo ago
Wow, if this is as good as it looks, I suspect I'll be using it quite a bit in the future, especially once it gets a brush engine!
Buttons840•6mo ago
Yes, it looks really good. I wonder if it will unseat Aseprite?
whizzter•6mo ago
Not necessarily, ASE is has a smooth UI that people like and as long as you're fine within the constraints.

This one is great since it allows for in-editor previewing of "weird" ideas, I know I've re-invented that UV-mapping workflow shown with the skeleton on the page once for a game-jam and wanted to use it but skipped it in the end since asset-creation was "annoying", having support in an editor to preview it easily can be a game-changer.

Buttons840•6mo ago
You mean ASE is more focused? Both look quite smooth, but PixiEditor seems to have more features (which inevitably leads to less focus).
andrekandre•6mo ago

msephton•6mo ago
As somebody who is currently making a native macOS-only 2D pixel editor...this has some cool stuff in it!
JKCalhoun•6mo ago
If your pixel-editor does just the one thing very well (and intuitively), I say keep going.

This app looks cool — but also looks to be heading into Blender-level complexity. A 21st Century MacPaint is still desirable.

msephton•6mo ago
Thanks! I will surely keep going. My app also has a bunch of novel features and brings back a bunch of functionality forgotten since the classic Macintosh era.

Perpetually reloads in Brave on iOS (never resolves).

You had my attention, now you have my interest… or however that quote goes.

Edit: Please please please add the `playsinline` attribute to your video elements. I’m on my phone, and every time I scroll a video explodes and takes over the whole screen.

jeroenhd•6mo ago
I've never heard of this property, what browser does this?
dindresto•6mo ago
iOS Safari
fmbb•6mo ago
Chrome, Edge, Opera, Safari support this attribute.

Do we finally have a new Fireworks?
WillAdams•6mo ago
The big feature I'd like to see is someone setting up the re-rendering PNG files which Fireworks had.
vyrotek•6mo ago
I had the exact same thought! I played with it a bit and I immediately thought of Fireworks. I still use it from CS6. Hopefully not anymore.
reactordev•6mo ago
Bones. Add 2D skeletal animation and I’ll gladly pay money for this.
register•6mo ago
I am working on Pixel Editor for retro graphics. What do you believe that ASE is missing? At the moment I am targetting the Zx Spectrum Next that I have recently backed. However if I get some compelling ideas I migth deviate from my original objective.
reactordev•6mo ago
For retro graphics, definitely a palette editor and animation tool. Frame by frame animation is one thing. Bone animation is better. UV indexed bone animation is best. But there’s something fucking magical about palette animated backgrounds. Color cycling animation.
HelloNurse•6mo ago
For an advanced palette editor (GIF class: 256 colours, one transparent) with first class support for color cycling, I suggest looking at FRACTINT.
ivanjermakov•6mo ago
FOSS? All I see is paid and no source.
mattbaker•6mo ago
You are mistaken, the source is available and the editor is free to download.
ethan_smith•6mo ago
The project is indeed FOSS - it's licensed under MIT according to their GitHub repository (https://github.com/PixiEditor/PixiEditor), though they offer a paid version with additional features.
Borealid•6mo ago
The repository says it's LGPL, not MIT-licensed.
mananaysiempre•6mo ago
Relicensed[1] under LGPL3 in 2023.

Always refreshing to see a new project opt for copyleft!
pull_my_finger•6mo ago
I thought I'd seen this posted just 2 days ago, it looks like that post is this post and the timestamp just got updated. I know HN boosts interesting posts that slips through the gaps, but I think it should be more transparent then just updating the timestamp and presenting it as a new post.
msephton•6mo ago
I agree, but it seems the managenent won't change the policy.
she46BiOmUerPVj•6mo ago
Looks fun. It's standard for software packaged for Linux to include a base directory in its tarball, and I usually check, but I did barf your application all over my /opt.

May sound crazy but I was hoping for export to terminal escape codes / box drawing chars. No biggie, I can convert the output.

mythz•6mo ago
I like it, works great in Fedora.

Looks like a great addition to the available image editors on Linux. IMO image editing is one of the few areas lagging in Linux. Currently alternating between Pinta, Krita, Gimp and photopea.com. Will switch to this for a while to see it become my new go to.

oneshtein•6mo ago
It doesn't fit my 2k screen on Fedora (X11/Mate) with no option to scale it down. It looks like 4k screens are supported only.
mythz•6mo ago
Yeah can confirm it looks great on my 4K
spookie•6mo ago
Krita is pretty good. I find the UX reasonable and G'MIC¹ is a joy to use in there.

F3nd0•6mo ago
I enjoy using GIMP. Most of my (not very advanced) needs are met quite well. Looking forward to try out the more recent versions too.
kelvinjps10•6mo ago
I don't think some stuff is reasonable, but for most stuff, I find it hard to use. And I don't come from Photoshop, so it's not like a problem of being used to another program or something
chilmers•6mo ago
I tried this for pixel art and came away a bit disappointed. It seems to have no real support for drawing using palettes / indexed colors. Sure, you can setup or load a palette, but the drawing tools make no reference to it, and continue to colors outside of it. The color pickers don't even show the palette, they just show the full color wheel. Where is the support for dithered gradients using on palette colors? Where is the support for antialiasing using only palette colors? Maybe this is planned, but given it's already at v2.0 I'm surprised the pixel art support is so half-baked.
ksymph•6mo ago
It's possible to implement dithering and posterization using the node graph, where you paint normally and it outputs as dithered pixel art in whatever palette you want. It's not a perfect replacement for builtin tools, but still pretty cool. Someone showed their setup for this in the Discord server.
JKCalhoun•6mo ago
That's cool that you can do that. I worry though that the level of complexity required to set that sort of thing up will act as a hurdle for many that might want to use that feature.

If the node graph is saved in the document (?) perhaps there exists then a "template" (empty document) where the node graph is already set up for palette dithering. That would make it easy to onboard for new users.

bentt•6mo ago
All I want is proper color channel editing like Photoshop has and Affinity refuses to do right.
archerx•6mo ago
Please elaborate, I’m working on an image editor made with JavaScript.
doobiedowner•6mo ago
