Free and Open

It runs in your browser, works on any system and works fine on touch-screen devices like iPads.
It is written in 100% plain JavaScript and has no dependencies.
It's 100% free, no ads, no tracking, no accounts, no nothing.
All processing is done in your browser, no data is sent to any server.

The only part that is not included in this repository is the Amiga Emulator Files. (The emulator is based on the Scripted Amiga Emulator)

Building

DPaint.js doesn't need building.
It also has zero dependencies so there's no need to install anything.
DPaint.js is written using ES6 modules and runs out of the box in modern browsers.
Just serve "index.html" from a webserver and you're good to go.

There's an optional build step to create a compact version of DPaint.js if you like.
I'm using Vite for this.
For convenience, I've included a "package.json" file.
open a terminal and run npm install to install Vite and its dependencies. Then run npm run build to create a compact version of DPaint.js in the "dist" folder.

Running offline

Dpaint.js is a web application, not an app that you install on your computer. That being said: DPaint.js has no online dependencies and runs fine offline if you want. One caveat: you have to serve the index.html file from a webserver, not just open it in your browser.
A quick way to do this is - for example - using the Spark app.
Download the binary for your platform, drop the Spark executable in the folder where you downloaded the Dpaint.js source files and run it. If you then point your browser to http://localhost:8080/ it should work.
But any webserver will do, you can also use the one built into Python for example. ( python -m http.server ) Or - if you have the node.js runtime installed - you can use packages like:

• serve: npx serve in the DPaint.js folder
• http-server: npx http-server in the DPaint.js folder

If you are using Chrome, you can also "install" dpaint.js as app.

It will then show up your Chrome apps and work offline.

Browser Quirks

Please note that the Brave browser is using "farbling" that introduces random image noise in certain conditions. They claim this is to protect your privacy. Although I totally understand the sentiment, In my opinion a browser should not actively alter the content of a webpage or intentionally break functionality.
But hey, who am I to speak, it's a free world. Just be aware that if you are using Brave, you will run into issues, so please "lower your shields" for this app in Brave or use another browser.

Color Cycling

Dpaint.js supports Color-Cycling - a long lost art of "animating" a static image by only rotating some colors in the palette. See an example here:
