Mostly useful for testing. * @property {string} [imgPath="images/"] The path where the SVG icons are located, with trailing slash. Note that as of version 2.7, this is not configurable by URL for security reasons. * @property {string} [langPath="locale/"] The path where the language files are located, with trailing slash. Default will be changed to `../dist/locale/` if this is a modular load. Note that as of version 2.7, this is not configurable by URL for security reasons. * @property {string} [extPath="extensions/"] The path used for extension files, with trailing slash. Default will be changed to `../dist/extensions/` if this is a modular load. Note that as of version 2.7, this is not configurable by URL for security reasons. * @property {string} [canvgPath="canvg/"] The path used for `canvg` files, with trailing slash. Default will be changed to `../dist/` if this is a modular load. * @property {string} [jspdfPath="jspdf/"] The path used for `jsPDF` files, with trailing slash.

Note that as of version 2.7, this is not configurable by URL for security reasons. * @property {boolean} [preventAllURLConfig=false] Set to `true` to override the ability for URLs to set non-content configuration (including extension config). Must be set early, i.e., in `svgedit-config-iife.js`; extension loading is too late! * @property {boolean} [preventURLContentLoading=false] Set to `true` to override the ability for URLs to set URL-based SVG content. Must be set early, i.e., in `svgedit-config-iife.js`; extension loading is too late! * @property {boolean} [lockExtensions=false] Set to `true` to override the ability for URLs to set their own extensions; disallowed in URL setting. There is no need for this when `preventAllURLConfig` is used. Must be set early, i.e., in `svgedit-config-iife.js`; extension loading is too late! * @property {boolean} [noDefaultExtensions=false] If set to `true`, prohibits automatic inclusion of default extensions (though "extensions" can still be used to add back any desired default extensions along with any other extensions). This can only be meaningfully used in `svgedit-config-iife.js` or in the URL * @property {boolean} [noStorageOnLoad=false] Some interaction with `ext-storage.js`; prevent even the loading of previously saved local storage. * @property {boolean} [forceStorage=false] Some interaction with `ext-storage.js`; strongly discouraged from modification as it bypasses user privacy by preventing them from choosing whether to keep local storage or not (and may be required by law in some regions) * @property {boolean} [emptyStorageOnDecline=false] Used by `ext-storage.js`; empty any prior storage if the user declines to store * @property {boolean} [avoidClientSide=false] DEPRECATED (use `avoidClientSideDownload` instead); Used by `ext-server_opensave.js`; set to `true` if you wish to always save to server and not only as fallback when client support is lacking * @property {boolean} [avoidClientSideDownload=false] Used by `ext-server_opensave.js`; set to `true` if you wish to always save to server and not only as fallback when client support is lacking * @property {boolean} [avoidClientSideOpen=false] Used by `ext-server_opensave.js`; set to `true` if you wish to always open from the server and not only as fallback when FileReader client support is lacking * @property {string[]} [extensions=module:SVGEditor~defaultExtensions] Extensions to load on startup. Use an array in `setConfig` and comma separated file names in the URL. Extension names must begin with "ext-". Note that as of version 2.7, paths containing "/", "\", or ":", are disallowed for security reasons. Although previous versions of this list would entirely override the default list, as of version 2.7, the defaults will always be added to this explicit list unless the configuration `noDefaultExtensions` is included. * @property {module:SVGEditor.Stylesheet[]} [stylesheets=["@default"]] An array of required stylesheets to load in parallel; include the value `"@default"` within this array to ensure all default stylesheets are loaded. * @property {string[]} [allowedOrigins=[]] Used by `ext-xdomain-messaging.js` to indicate which origins are permitted for cross-domain messaging (e.g., between the embedded editor and main editor code). Besides explicit domains, one might add '*' to allow all domains (not recommended for privacy/data integrity of your user's content!), `window.location.origin` for allowing the same origin (should be safe if you trust all apps on your domain), 'null' to allow `file:///` URL usage * @property {null|PlainObject} [colorPickerCSS=null] Object of CSS properties mapped to values (for jQuery) to apply to the color picker. See {@link http://api.jquery.com/css/#css-properties}. A `null` value (the default) will cause the CSS to default to `left` with a position equal to that of the `fill_color` or `stroke_color` element minus 140, and a `bottom` equal to 40 * @property {string} [paramurl] This was available via URL only. Allowed an un-encoded URL within the query string (use "url" or "source" with a data: URI instead) * @property {Float} [canvas_expansion=3] The minimum area visible outside the canvas, as a multiple of the image dimensions. The larger the number, the more one can scroll outside the canvas. * @property {PlainObject} [initFill] Init fill properties * @property {string} [initFill.color="FF0000"] The initial fill color. Must be a hex code string. Defaults to solid red. * @property {Float} [initFill.opacity=1] The initial fill opacity. Must be a number between 0 and 1 * @property {PlainObject} [initStroke] Init stroke properties * @property {Float} [initStroke.width=5] The initial stroke width. Must be a positive number. * @property {string} [initStroke.color="000000"] The initial stroke color. Must be a hex code. Defaults to solid black. * @property {Float} [initStroke.opacity=1] The initial stroke opacity. Must be a number between 0 and 1. * @property {PlainObject} text Text style properties * @property {Float} [text.stroke_width=0] Text stroke width * @property {Float} [text.font_size=24] Text font size * @property {string} [text.font_family="serif"] Text font family * @property {Float} [initOpacity=1] Initial opacity (multiplied by 100) * @property {module:SVGEditor.XYDimensions} [dimensions=[640, 480]] The default width/height of a new document. Use an array in `setConfig` (e.g., `[800, 600]`) and comma separated numbers in the URL. * @property {boolean} [gridSnapping=false] Enable snap to grid by default. Set in Editor Options. * @property {string} [gridColor="#000"] Accepts hex, e.g., '#000'. Set in Editor Options. Defaults to black. * @property {string} [baseUnit="px"] Set in Editor Options. * @property {Float} [snappingStep=10] Set the default grid snapping value. Set in Editor Options. * @property {boolean} [showRulers=true] Initial state of ruler display (v2.6). Set in Editor Options. * @property {string} [initTool="select"] The initially selected tool. Must be either the ID of the button for the tool, or the ID without `tool_` prefix (e.g., "select"). * @property {boolean} [wireframe=false] Start in wireframe mode * @property {boolean} [showlayers=false] Open the layers side-panel by default. * @property {"new"|"same"} [exportWindowType="new"] Can be "new" or "same" to indicate whether new windows will be generated for each export; the `window.name` of the export window is namespaced based on the `canvasName` (and incremented if "new" is selected as the type). Introduced 2.8. * @property {boolean} [showGrid=false] Set by `ext-grid.js`; determines whether or not to show the grid by default * @property {boolean} [show_outside_canvas=true] Defines whether or not elements outside the canvas should be visible. Set and used in `svgcanvas.js`. * @property {boolean} [selectNew=true] If true, will replace the selection with the current element and automatically select element objects (when not in "path" mode) after they are created, showing their grips (v2.6). Set and used in `svgcanvas.js` (`mouseUp`). * @todo Some others could be preferences as well (e.g., preventing URL changing of extensions, defaultExtensions, stylesheets, colorPickerCSS); Change the following to preferences and add pref controls where missing to the UI (e.g., `canvas_expansion`, `initFill`, `initStroke`, `text`, `initOpacity`, `dimensions`, `initTool`, `wireframe`, `showlayers`, `gridSnapping`, `gridColor`, `baseUnit`, `snappingStep`, `showRulers`, `exportWindowType`, `showGrid`, `show_outside_canvas`, `selectNew`)? */ /** * @namespace {module:SVGEditor.Config} defaultConfig * @memberof module:SVGEditor~ * @implements {module:SVGEditor.Config} */ defaultConfig = { canvasName: 'default', canvas_expansion: 3, initFill: { color: 'FF0000', // solid red opacity: 1 }, initStroke: { width: 5, color: '000000', // solid black opacity: 1 }, text: { stroke_width: 0, font_size: 24, font_family: 'serif' }, initOpacity: 1, colorPickerCSS: null, // Defaults to 'left' with a position equal to that of the fill_color or stroke_color element minus 140, and a 'bottom' equal to 40 initTool: 'select', exportWindowType: 'new', // 'same' (todo: also support 'download') wireframe: false, showlayers: false, no_save_warning: false, // PATH CONFIGURATION // The following path configuration items are disallowed in the URL (as should any future path configurations) langPath: 'locale/', // Default will be changed if this is a non-modular load extPath: 'extensions/', // Default will be changed if this is a non-modular load canvgPath: 'canvg/', // Default will be changed if this is a non-modular load jspdfPath: 'jspdf/', // Default will be changed if this is a non-modular load imgPath: 'images/', jGraduatePath: 'jgraduate/images/', extIconsPath: 'extensions/', // DOCUMENT PROPERTIES // Change the following to a preference (already in the Document Properties dialog)? dimensions: [640, 480], // EDITOR OPTIONS // Change the following to preferences (already in the Editor Options dialog)? gridSnapping: false, gridColor: '#000', baseUnit: 'px', snappingStep: 10, showRulers: true, // URL BEHAVIOR CONFIGURATION preventAllURLConfig: false, preventURLContentLoading: false, // EXTENSION CONFIGURATION (see also preventAllURLConfig) lockExtensions: false, // Disallowed in URL setting noDefaultExtensions: false, // noDefaultExtensions can only be meaningfully used in `svgedit-config-iife.js` or in the URL // EXTENSION-RELATED (GRID) showGrid: false, // Set by ext-grid.js // EXTENSION-RELATED (STORAGE) noStorageOnLoad: false, // Some interaction with ext-storage.js; prevent even the loading of previously saved local storage forceStorage: false, // Some interaction with ext-storage.js; strongly discouraged from modification as it bypasses user privacy by preventing them from choosing whether to keep local storage or not emptyStorageOnDecline: false, // Used by ext-storage.js; empty any prior storage if the user declines to store // EXTENSION (CLIENT VS.
