Members

The SVGPatternElement object has these types of members:

Events

The SVGPatternElement object has these events.

EventDescription
onload

Occurs when the browser has fully parsed the element and all of its descendants.

 

Methods

The SVGPatternElement object has these methods.

MethodDescription
hasExtension

Determines if the specified extension is supported.

 

Properties

The SVGPatternElement object has these properties.

PropertyDescription

className

Gets the names of the classes that are assigned to this object.

clipPath

Sets or retrieves a reference to the SVG graphical object that will be used as the clipping path.

externalResourcesRequired

Gets a value that indicates whether referenced resources that are not in the current document are required to correctly render a given element.

focusable

Determines if an element can acquire keyboard focus (that is, receive keyboard events) and be a target for field-to-field navigation actions (such as when a user presses the Tab key).

height

Gets or sets the height of an element.

href

Gets an xlink:href attribute of an element.

mask

Sets or retrieves a value that indicates a SVG mask.

ownerSVGElement

Gets the nearest ancestor svg element.

patternContentUnits

Gets or sets the patternContentUnits property on the given pattern element, defining the coordinate system for the contents of the pattern element.

patternTransform

Gets or sets the definition of an optional transformation from the pattern coordinate system onto the target coordinate system.

patternUnits

Gets or sets the patternUnits property on the given pattern element, defining the coordinate system for attributes x, y, width and height.

preserveAspectRatio

Gets an XML value that indicates whether to force uniform graphic scaling.

requiredExtensions

Gets a white space-delimited list of required language extensions.

requiredFeatures

Gets or sets a white space-delimited list of feature strings.

style

Gets a style object.

systemLanguage

Gets or sets a comma-separated list of language names.

viewBox

Gets a value that indicates how a graphic scales to fit a container element.

viewportElement

Gets the element that established the current viewport.

width

Defines the width of an element.

x

Gets or sets the x-coordinate value.

xmlbase

Gets or sets the base attribute on the element.

xmllang

Gets or sets a value that specifies the language that is used in the contents and attribute values of an element.

xmlspace

Gets or sets a value that indicates whether white space is preserved in character data.

y

Gets or sets the y-coordinate value.

Remarks

Note  In addition to the attributes, properties, events, methods, and styles listed above, SVG elements also inherit core HTML attributes, properties, events, methods, and styles.

You can use a pattern to fill or stroke an object by using a predefined graphic object that is replicated (that is, tiled) at fixed intervals along the x-axis and y-axis to cover the areas to be painted. You can define a pattern by using a pattern element. You can then reference the pattern by the fill and stroke properties on a given graphics element to specify that the given element is filled or stroked with the referenced pattern.

The x, y, width, height, and patternUnits attributes define a reference rectangle somewhere on the infinite SVG canvas. The reference rectangle has its upper-left corner at (x, y) and its lower-right corner at (x + width, y + height). The tiling theoretically extends a series of such rectangles to infinity along the x-axis (positive) and y-axis (negative), with rectangles starting at (x + m·width, y + n·height) for each possible m and n integer value.

Examples

In the following code example, a pattern fills a circle. The pattern is made up of a repeated series of wedge-shaped paths. Copy this sample to a text file and save it with the .html file extension. Run it in Internet Explorer 9 to see the pattern-filled circle.

The pattern-filled circle will look like this:
