See the dojox/gfx/_gfxBidiSupport reference documentation for more information.
This the graphics rendering bridge for W3C Canvas compliant browsers. Since Canvas is an immediate mode graphics api, with no object graph or eventing capabilities, use of this module alone will only add in drawing support. The additional module, canvasWithEvents extends this module with additional support for handling events on Canvas. By default, the support for events is now included however, if only drawing capabilities are needed, canvas event module can be disabled using the dojoConfig option, canvasEvents:true|false. The id of the Canvas renderer is 'canvas'. This id can be used when switch Dojo's graphics context between renderer implementations. See dojox/gfx/_base.switchRenderer API.
This the graphics rendering bridge for W3C Canvas compliant browsers which extends the basic canvas drawing renderer bridge to add additional support for graphics events on Shapes. Since Canvas is an immediate mode graphics api, with no object graph or eventing capabilities, use of the canvas module alone will only add in drawing support. This additional module, canvasWithEvents extends this module with additional support for handling events on Canvas. By default, the support for events is now included however, if only drawing capabilities are needed, canvas event module can be disabled using the dojoConfig option, canvasEvents:true|false.
An object specifying the default properties for a Font used in text operations.
An object defining the default stylistic properties used for Linear Gradient fills. Linear gradients are drawn along a virtual line, which results in appearance of a rotated pattern in a given direction/orientation.
An object specifying the default properties for a Pattern using in fill operations.
An object specifying the default properties for RadialGradients using in fills patterns.
A stroke defines stylistic properties that are used when drawing a path. This object defines the default Stroke prototype.
Defines how to fill a shape. Four types of fills can be used: solid, linear gradient, radial gradient and pattern. See dojox/gfx.LinearGradient, dojox/gfx.RadialGradient and dojox/gfx.Pattern respectively for more information about the properties supported by each type.
An object specifying the properties for a Font used in text operations.
An object defining the default stylistic properties used for Linear Gradient fills. Linear gradients are drawn along a virtual line, which results in appearance of a rotated pattern in a given direction/orientation.
This module contains the core graphics Path API. Path command format follows the W3C SVG 1.0 Path api.
a constant regular expression used to split a SVG/VML path into primitive components
An object specifying the default properties for a Pattern using in fill operations.
Specifies the properties for RadialGradients using in fills patterns.
Either the string name of a renderer (eg. 'canvas', 'svg, ...) or the renderer object to switch to.
This module contains the core graphics Shape API. Different graphics renderer implementation modules (svg, canvas, vml, silverlight, etc.) extend this basic api to provide renderer-specific implementations for each shape.
This the graphics rendering bridge for the Microsoft Silverlight plugin. Silverlight is a faster implementation on IE6-8 than the default 2d graphics, VML
A stroke defines stylistic properties that are used when drawing a path.
This the graphics rendering bridge for browsers compliant with W3C SVG1.0. This is the preferred renderer to use for interactive and accessible graphics.
This the default graphics rendering bridge for IE6-7. This renderer is very slow. For best performance on IE6-8, use Silverlight plugin. IE9+ defaults to the standard W3C SVG renderer.

Decompose a 2D matrix into translation, scaling, and rotation components.
This function decompose a matrix into four logical components: translation, rotation, scaling, and one more rotation using SVD. The components should be applied in following order:
[translate, rotate(angle2), scale, rotate(angle1)]

| Parameter | Type | Description |
|---|---|---|
| x | Number | number to be converted |
| addSpace | Boolean | whether to add a space before a positive number |
the formatted value
converts a font object to a CSS font string
| Parameter | Type | Description |
|---|---|---|
