How to use:
1. Create the SVG master file that includes all icons:
The master SVG icon-containing file is an SVG file that contains
<g> elements. Each <g> element should contain the markup of an SVG
icon. The <g> element has an ID that should
correspond with the ID of the HTML element used on the page that should contain
or optionally be replaced by the icon. Additionally, one empty element should be
added at the end with id "svg_eof".
2. Optionally create fallback raster images for each SVG icon.
3. Include the jQuery and the SVG Icon Loader scripts on your page.
4. Run $.svgIcons() when the document is ready:
$.svgIcons( file [string], options [object literal]);
File is the location of a local SVG or SVGz file.
All options are optional and can include:
- 'w (number)': The icon widths
- 'h (number)': The icon heights
- 'fallback (object literal)': List of raster images with each
key being the SVG icon ID to replace, and the value the image file name.
- 'fallback_path (string)': The path to use for all images
listed under "fallback"
- 'replace (boolean)': If set to true, HTML elements will be replaced by,
rather than include the SVG icon.
- 'placement (object literal)': List with selectors for keys and SVG icon ids
as values. This provides a custom method of adding icons.
- 'resize (object literal)': List with selectors for keys and numbers
as values. This allows an easy way to resize specific icons.
- 'callback (function)': A function to call when all icons have been loaded.
Includes an object literal as its argument with as keys all icon IDs and the
icon as a jQuery object as its value.
- 'id_match (boolean)': Automatically attempt to match SVG icon ids with
corresponding HTML id (default: true)
- 'no_img (boolean)': Prevent attempting to convert the icon into an <img>
element (may be faster, help for browser consistency)
- 'svgz (boolean)': Indicate that the file is an SVGZ file, and thus not to
parse as XML. SVGZ files add compression benefits, but getting data from
them fails in Firefox 2 and older.
5. To access an icon at a later point without using the callback, use this:
$.getSvgIcon(id (string));
This will return the icon (as jQuery object) with a given ID.
6. To resize icons at a later point without using the callback, use this:
$.resizeSvgIcons(resizeOptions) (use the same way as the "resize" parameter)
Example usage #1:
$(function() {
$.svgIcons('my_icon_set.svg'); // The SVG file that contains all icons
// No options have been set, so all icons will automatically be inserted
// into HTML elements that match the same IDs.
});
Example usage #2:
$(function() {
$.svgIcons('my_icon_set.svg', { // The SVG file that contains all icons
callback: function(icons) { // Custom callback function that sets click
// events for each icon
$.each(icons, function(id, icon) {
icon.click(function() {
alert('You clicked on the icon with id ' + id);
});
});
}
}); //The SVG file that contains all icons
});
Example usage #3:
$(function() {
$.svgIcons('my_icon_set.svgz', { // The SVGZ file that contains all icons
w: 32, // All icons will be 32px wide
h: 32, // All icons will be 32px high
fallback_path: 'icons/', // All fallback files can be found here
fallback: {
'#open_icon': 'open.png', // The "open.png" will be appended to the
// HTML element with ID "open_icon"
'#close_icon': 'close.png',
'#save_icon': 'save.png'
},
placement: {'.open_icon','open'}, // The "open" icon will be added
// to all elements with class "open_icon"
resize: function() {
'#save_icon .svg_icon': 64 // The "save" icon will be resized to 64 x 64px
},
callback: function(icons) { // Sets background color for "close" icon
icons['close'].css('background','red');
},
svgz: true // Indicates that an SVGZ file is being used
})
});

jGraduate( options, okCallback, cancelCallback )
where options is an object literal:
{
window: { title: "Pick the start color and opacity for the gradient" },
images: { clientPath: "images/" },
paint: a Paint object,
newstop: String of value "same", "inverse", "black" or "white"
OR object with one or both values {color: #Hex color, opac: number 0-1}
}
- the Paint object is:
Paint {
type: String, // one of "none", "solidColor", "linearGradient", "radialGradient"
alpha: Number representing opacity (0-100),
solidColor: String representing #RRGGBB hex of color,
linearGradient: object of interface SVGLinearGradientElement,
radialGradient: object of interface SVGRadialGradientElement,
}
$.jGraduate.Paint() -> constructs a 'none' color
$.jGraduate.Paint({copy: o}) -> creates a copy of the paint o
$.jGraduate.Paint({hex: "#rrggbb"}) -> creates a solid color paint with hex = "#rrggbb"
$.jGraduate.Paint({linearGradient: o, a: 50}) -> creates a linear gradient paint with opacity=0.5
$.jGraduate.Paint({radialGradient: o, a: 7}) -> creates a radial gradient paint with opacity=0.07
$.jGraduate.Paint({hex: "#rrggbb", linearGradient: o}) -> throws an exception?
- picker accepts the following object as input:
{
okCallback: function to call when Ok is pressed
cancelCallback: function to call when Cancel is pressed
paint: object describing the paint to display initially, if not set, then default to opaque white
}
- okCallback receives a Paint object
