A Map of label integer to\nfloat, 0.0 to 1.0, weight.\nstring values.\n\n### setImageScale(resolutionScale)\n\nresolutionScale is a integer with 0 being the most detailed scale.\n\n### setCompareImages(fixedImageName, movingImageName, options)\n\nPost processing to detect difference in images. The moving and fixed images are separately\ncompressed to one component with a vector magnitude or luminance filter. Then, the moving image is\nre-sampled to the fixed image space. The final rendered image has the fixed image on the first component,\nthe moving image is on the second component.\n\nThe moving image must have been added last.\n\n`options` is an Object with:\n\n```\n{\n method: 'checkerboard' | 'cyan-magenta' | 'blend' | 'disabled',\n imageMix?: number,\n checkerboard?: boolean,\n pattern?: number[],\n swapImageOrder?: boolean\n}\n```\n\n`method` can be `blend`, `green-magenta`, `cyan-red`, `cyan-magenta`, `checkerboard`, or `disabled`.\n`blend` simply initiates the comparison composition of images.\n`cyan-magenta` changes the color map for fixed image to cyan, moving image to magenta. If images match perfectly, the color will be purple.\n`green-magenta` and `cyan-red` changes the color map for the fixed and moving image. If images match, the color will be gray/white.\n`checkerboard` is equivalent to `blend` with `imageMix` set to `0`.\n\n`imageMix` changes the percent contribution the fixed vs moving image makes to the\nrender by modifying the opacity transfer function. Value of 1 means max opacity for\nmoving image, 0 for fixed image.\n\n`checkerboard` picks pixels from the fixed and moving image to create a\ncheckerboard pattern. The 2 components in the output image differ by the\nimage order for each checkerboard box.\n\n`pattern` is an array with the number of checkerboard boxes for each dimension.\nIf pattern === undefined, it defaults to 4 boxes across each dimension\n\n`swapImageOrder` toggles the checkerboard pattern by switching the imageMix parameter between 0 and 1.\n" }, { "path": "doc/content/config/index.md", "content": "title: Config\n---\n\nThis documentation provides more detailed information about the viewer configuration.\n\nThe viewer configuration is a JSON-serializable JavaScript object in the browser and Python dictionary in a Python environment.\n\nTo obtain a viewer's configuration, call the [viewer API `getConfig()` method](../api/).\n\nPass a viewer's configuration during creation with the `config` option.\n\nThe followings sections describe the configuration fields.\n\n## Viewer Config\n\n### viewerConfigVersion\n\nThis is a \"major.minor\" version of the configuration.

An existing viewer user interface can be tweaked, or a new user interface can be built from scratch. Use vanilla HTML/CSS/JavaScript or your favorite UI framework, such as React.js or Vue.js.\n\nThe user interface is specified on viewer creation with a JavaScript object or an object that specifies an [ES Module](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules). The UI object should contain functions that implement **actions** called as UI [state machines](https://xstate.js.org/docs/) respond to events. Nested objects provide actions for child state machines. A few example actions are `toggleDarkMode` or `toggleUICollapsed`.\n\nEach [action function](https://xstate.js.org/docs/about/glossary.html#action) is expected to accept two arguments: `context` and `event`.\n\nThe `context` is the current state machine context. A `context` object is comprised of the context generated by the [viewer configuration](../config/) and additional objects generated by the UI or renderer. For example, the `createInterface` action may add a `div` property to the `context` for the UI that other UI actions may reference later.\n\nThe `event` argument is the current event object that triggered the action. An `event` object contains the event name, an upper case string by convention. Optionally, the `event` may contain a payload in the `data` property. In addition to responding to events, a UI implementation will trigger events from user input and pass those events to the state machine by calling `context.service.send()`. For example,\n\n```\ncollapseUIButton.addEventListener('click', () => { context.service.send('TOGGLE_UI_COLLAPSED'))\n```\n\n## UI options architecture\n\n**Warning**: the viewer machine's architecture is experimental and it is subject to change without modification to the major version of the package. We mean it!\n\nAvailable actions can be observed in the [Reference UI Machine Options](https://github.com/Kitware/itk-vtk-viewer/blob/master/src/UI/reference-ui/src/referenceUIMachineOptions.js). If an action is not implemented, it is a no-op. Nested options objects correspond to the nested state machines. They are:\n\n* [`main`](https://github.com/Kitware/itk-vtk-viewer/blob/master/src/UI/Reference/Main/mainUIMachineOptions.js): UI components impacting the entire viewer's state. For example, the UI to toggle fullscreen mode or change the viewer's background color.\n* [`layers`](https://github.com/Kitware/itk-vtk-viewer/blob/master/src/UI/Reference/Layers/layersUIMachineOptions.js): UI components related to dataset layers. For example, the UI to select a layer or toggle its visibility.\n* [`widgets`](https://github.com/Kitware/itk-vtk-viewer/blob/master/src/UI/Reference/Widgets/widgetsUIMachineOptions.js): UI components for interactive widget parameters. For example, display the current distance measured by a distance widget.\n* [`images`](https://github.com/Kitware/itk-vtk-viewer/blob/master/src/UI/Reference/Images/imagesUIMachineOptions.js): UI components related to the currently selected image layer. For example, the current color map used.\n* `geometries` (todo): UI components related to the currently selected geometry layer. For example, the current geometry opacity.\n* `pointSets` (todo): UI components related to the currently selected point set layer. For example, the current point set opacity.\n\n## Example: Main UI with only a screenshot button\n\nThis example demonstrates how to customize the `reference` UI so the `main` interface only presents a screenshot button.\n\n### Create repository\n\nLet's create a repository for our interface.\n\nEither use the *Use this template* button on the [itk-viewer-reference-ui-template GitHub repository](https://github.com/InsightSoftwareConsortium/itk-viewer-reference-ui-template):\n\n![itk-viewer-reference-ui-template button](./referenceUITemplateGitHub.png)\n\nor use the template repository on the command line:\n\n```\nnpx degit InsightSoftwareConsortium/itk-viewer-reference-ui-template my-viewer-ui\n```\n\n### Edit interface\n\nTo create our interface, first install the Node.js packages:\n\n```\ncd my-viewer-ui\nnpm ci\n```\n\nThen start the development server:\n\n```\nnpm run dev\n```\n\nAnd visit *http://localhost:3000* in your web browser. The template has customized the viewer's [Reference UI](https://www.npmjs.com/package/itk-viewer-reference-ui) to only present a screenshot button in the viewer's main interface. The main interface is customized with the `createMainInterface` action.\n\n```\nimport referenceUIMachineOptions from 'itk-viewer-reference-ui/src/referenceUIMachineOptions.js'\nimport style from 'itk-viewer-reference-ui/src/ItkVtkViewer.module.css'\nimport createScreenshotButton from 'itk-viewer-reference-ui/src/Main/createScreenshotButton.js'\n\nfunction modifiedCreateMainInterface(context) {\n const mainUIGroup = document.createElement('div')\n mainUIGroup.setAttribute('class', style.uiGroup)\n context.uiGroups.set('main', mainUIGroup)\n\n const mainUIRow1 = document.createElement('div')\n mainUIRow1.setAttribute('class', style.mainUIRow)\n mainUIGroup.appendChild(mainUIRow1)\n\n createScreenshotButton(context, mainUIRow1)\n\n context.uiContainer.appendChild(mainUIGroup)\n}\n```\n\n![screenshot button](./screenshotButton.png)\n\nWe re-use the rest of the user interface machine actions:\n\n```\nconst uiMachineOptions = { ...referenceUIMachineOptions }\n\nconst uiMainActions = { ...uiMachineOptions.main.actions }\nuiMainActions.createMainInterface = modifiedCreateMainInterface\n\nconst uiMain = { ...uiMachineOptions.main }\nuiMain.actions = uiMainActions\nuiMachineOptions.main = uiMain\n```\n\nAnd use the `uiMachineOptions` as the default module export:\n\n```\nexport default uiMachineOptions\n```\n\nLet's make the background of the main user interface green by editing *main.js*:\n\n```\n [...]\n createScreenshotButton(context, mainUIRow1)\n\n // Add this line\n mainUIGroup.style.backgroundColor = \"green\"\n\n context.uiContainer.appendChild(mainUIGroup)\n [...]\n```\n\nAfter saving *main.js*, the page will reload with our change applied:\n\n![screenshot button green](./screenshotButtonGreen.png)\n\n### Publish the UI module\n\nExit the development server with *Ctrl+C* if still open, then build a production version of the user interface module:\n\n```\nnpm run build\n```\n\nThis builds the module `dist/referenceUIMachineOptions.js.es.js`.\n\nWe can publish our interface to [npmjs.com](https://www.npmjs.com/). First change the package `name` in the *package.json* file to something unique:\n\n```\n{\n \"version\": \"0.1.0\",\n \"name\": \"my-viewer-ui\",\n \"scripts\": {\n```\n\nThen publish the package:\n\n```\nnpm login\nnpm publish\n```\n\nAfter published and propagated on the network, your package is available for download. The package files are also served by services like [jsdelivr](https://jsdelivr.com) (better for production use) or [unpkg](https://unpkg.com) (better for testing). Use your user interface by specifying it in the [viewer config](../config.html):\n\n```\nconst uiMachineOptions = { href: \"https://cdn.jsdelivr.net/npm/itk-viewer-reference-ui-template@0.1.2/dist/referenceUIMachineOptions.js.es.js\" }\n// or\n// const uiMachineOptions = { href: \"https://unpkg.com/itk-viewer-reference-ui-template@0.1.2/dist/referenceUIMachineOptions.js.es.js\" }\nitkVtkViewer.createViewer(container,\n {\n image: ipfsImage,\n rotate: false,\n config: { uiMachineOptions },\n })\n```\n" }, { "path": "doc/content/docs/embeddedViewer.md", "content": "title: Embedded Viewer\n---\n\nITK/VTK Viewer can be used within an existing web site as a library to embed interactive 3D visualizations for remote or local datasets.
