Klecks (German for "splash of color", pronounced "clex") is the official open-source release of the community-funded online painting app Kleki. Klecks and Kleki are by developer/artist bitbof. Klecks offers the same features as Kleki but might diverge slightly in the future.

Klecks was originally written in JavaScript and made the switch to TypeScript in December 2021. It uses Parcel as a bundler. Glfx.js is used for the filters. Ag-psd is used for PSD import/export.

Klecks can either run in standalone mode (e.g. on kleki.com), or as an embed (e.g. on 2draw.net). The embed can be included on an existing page, and used for something like a drawing community where people draw and revise their works with Klecks, which are then uploaded. Using it inside of an iframe is not recommended due to various browser bugs.

For a demo and list of features visit kleki.com/home. For future plans check here: kleki.com/about.

Commands

• initialize via npm install (requires node and npm to be installed already)
• npm run lang:build - generate language files necessary to run Klecks
• npm run start - dev server (to run it locally)
• npm run build - build standalone into /dist/
• npm run build:embed - build of embed into /dist/
• npm run build:help - build help page (when clicking the questionmark) into /dist/

Embed

Example usage of the embed can be found under: /examples/embed/

Docker

To run Klecks (standalone) within a Docker container, run the following commands in project root:

docker-compose build

docker-compose up -d

It is then accessible through: http://localhost:5050

Translations

Are you a native speaker or have advanced skills in a language with no translation yet? Any contribution by you is highly encouraged and appreciated! These are the currently available languages:

• English
• French
• German
• Japanese
• Chinese (simplified)
• Chinese (traditional)

Where are translation files?

Translations are located in src/languages where each translation is its own JSON5 file, e.g. de.json5 for German. Within such a file everything except value is to be kept in sync with _base-en.json5.

Structure of a translation file

{
  // key by which this text is referenced in code
  stabilizer: {
    
    // A hint, further explaining the text
    hint: 'Common feature in drawing software to make lines smoother',
    
    // Original text (English)
    original: 'Stabilizer',
    
    // Translated text
    value: '抖动修正'
  },
  // ...
}

Creating/editing a translation

To create a new translation run npm run lang:add <code>, which creates src/languages/<code>.json5. You find all (ISO 639-1) language codes in src/languages/languages.json. The generated file will already include everything except value. To edit an existing translation, simply edit one of the files in src/languages. If a language file is out of sync with src/languages/_base-en.json5 (English), whatever key is out of sync will be ignored and fall back on English. English is the source of truth. A translation cannot add new keys without them also being present in _base-en.json5.

To see your changes in Klecks, run npm run lang:build. It needs to be run whenever changes to src/languages are made or it won't be up-to-date. Then build or start Klecks.

A translation should try not to cause additional line-breaks in the UI if possible. Test to make sure translations fit the context of the application. Note, some texts are only visible in the standalone-version and vice versa with the embed-version.

List of commands

• npm run lang:add <code> - creates new language file src/languages/<code>.json5.
  • See (ISO 639-1) language codes in src/languages/languages.json
• npm run lang:sync <code> - synchronizes with base file. (TODO)
• npm run lang:build - generates JSON & TS files in src/app/languages
  • Problems are printed to the command line output
