Pixi Paint – A Simple Pixel Editor

I was working on an HTML5 canvas pixel editor at some point. It was rather frustrating dealing with the Retina display, blurred edges, and anti-aliasing. I'm curious if this situation has improved at all.

Yeah, the situation is still pretty grim. I spent a good half week trying to get canvases scaling while maintaining chunky pixels across multiple browsers and finally gave up. In Goya, all of the pixels are drawn as rects. I actually read your 'drawing pixels is hard' article two or three times while I was trying to track down a good solution.

Sorry my comment was not clear - I'm not the author of the linked article, but it's a good primer on the issue (even though I believe some of the solutions are out of date).

I also rendered pixels using rectangles and lines using my own routines. If I recall correctly, the editor worked fine when zoomed in 4x-8x. The problem was rendering the image 1:1 or 2:1. The rendered image looked a bit blurry compared to Graphics Gale and grafx2 (the two pixel editors I was using for inspiration).

Here's another pixel editor, but this time made with ClojureScript and Om (React-based framework).

Cool. I notice the persistent data structures pulling their weight on the right hand side of the window.

I notice it has DawnBringer's 16-color palette. Excellent.

Noticed it too. It's a fabulous palette :)

Any interest in packaging a portable version in PortableApps.com Format? I've already done a Launcher that handles node webkit for 2048 Portable. I can help you with a Windows icon and installer if you're interested as well.

I'm interested. Open up an issue here https://github.com/STRd6/pixel-editor/issues?state=open and we can start the discussion.

Really nice work! The symmetry controls are super clever.

Thanks! I hope our pixel editors can influence one another in positive ways.

Thanks for the feedback!

It's primary use case is for limited size and limited palette images, generally < 512x512 and 32 or 64 colors. It is a pixel editor not a photo editor :)

Though maybe I should give up and display a popup if someone is opening a file it will be unlikely to handle.
