Lucienne - A IIIF pattern generator

This is a web component to build patterns from IIIF manififests - like from wall papers. It's also possible to pass a collection like the default one to load a sample from it. For more background see this blog article-

Demo

A demo is available at https://cmahnke.github.io/lucienne/.

Name

The software is named after Lucienne_Day, a famous British textile and wallpaper designer.

Installation

npm i @projektemacher/lucienne

Usage

Make sure you have a HTMLElement to attach the generator to:

<div id="generator"></div>

Then (either in a script element or a JavaScript module) pass the

const urls = [
  { url: "https://vorsatzpapier.projektemacher.org/patterns/collection.json", label: "Sammlung Vorsatzpapier" }
];
const generatorElement = document.querySelector<HTMLDivElement>("#generator")!;
const cuttingTable = new CuttingTable(generatorElement, true, true, true, true, urls, false);

See next sections for options.

Parameters

| Parameter | Type | Default | Description | | -------------- | ------------------------------------------------------------------- | ----------- | --------------------------------------------------------------------------------------------------------- | | element | HTMLDivElement | — | The container element where the CuttingTable interface will be rendered. | | urlInput | boolean | true | Whether to display a URL input field for specifying image sources. | | gridSelector | boolean | true | Whether to enable grid selection controls for layout configuration. | | download | boolean | true | Whether to enable download functionality for exported JSON data. | | autoLoad | boolean | true | Whether to automatically load the first configured URL upon initialization. | | urls | URL \| Array<{url: string, label: string}> \| string \| undefined | undefined | Optional initial URLs to load. Can be a single URL, an array of URL objects with labels, or a string URL. | | shifts | boolean | false | Whether to enable shift controls for offset adjustments. |

Throws

• Error if no valid element is provided or if no initial URL is set when urlInput is false.

Development

This package uses Vite for development.

Dev browser mode

npm run dev

Test URL

http://localhost:5173/patterns/?url=https://static.projektemacher.org/vorsatzpapier/post/tapete-47/front

Generating JSDoc

npm run jsdoc

One can view the JSDoc using serve

npm install -g serve
serve public/jsdoc

Open http://localhost:3000

Packaging

Vite is sadly not very flexible in regard of creating distributable artifacts, thus we use Rollup for that.

npm run build

It's also possible to use vite to build the test and debug site:

npm run vite-build

Updating OpenSeadragon types

Since version 0.1.1 (and thus OpenSeadragon 6) the types aren't provides by @tyoes/openseadragon anymore, they are now provided by src/@types/openseadragon/index.d.ts which is used to override the provided types. Those are currently hand crafted.

TODO

Known issues

• Preview icon in collections, implemented but parser doesn't support it

Next Version(s)

• Pass cuts via URL
• Use a options object in constructor
• Select download area from result viewer
• Shifts / offsets
  • Dynamic margins not clipped correctly at edges
    • insets nor working with clippings
    • check margins wit offsets in two dimensions
  • Rotation not working with offsets
• Make sure everything is reset when changing the size - NTH
• Check how the augmented types could be generated
