W3C publications may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to cite a W3C Working Draft as anything other than a "work in progress."

Table of contents

1. Introduction

It has been established by industry demand, overwhelming support in the SVG working group and requests from the SVG developer community that some form of SVG suited to displaying vector graphics on small devices is required. Moreover, the mission statement of SVG 1.0 specifically addresses small devices as a target area for vector graphics display. In order to meet these demands the SVG Working Group has committed to a concerted effort to create a profile specification that addresses mobile devices.

A single such profile is not sufficient to deal with the variety of mobile devices, because each mobile device has different characteristics in terms of CPU speed, memory size, and color support. To address the range of different device families, two profiles are defined. The first low-level profile, SVG Tiny (SVGT) is suitable for highly restricted mobile devices; while the second profile, SVG Basic (SVGB) is targeted for higher level mobile devices.

Because of the low memory, low CPU power and limited display of mobile devices, Mobile SVG profiles introduce constraints on content, attribute types, properties, and user agent behavior. This section describes these constraints and design rationale behind them.

  1. Two profiles are designed to allow SVG to render on mobile devices with limited memory, CPU power, and bandwidth.
  2. Mobile SVG profiles attempt to maximize compatibility with SVG 1.0 to display existing content.
  3. A true subset of the SVG 1.0 imaging model is maintained.
  4. Mobile SVG is designed to facilitate export from authoring tools.
  5. Mobile SVG is designed so that SVG 1.1 can be transcoded into SVGB and SVGT preserving as much scalability as possible.
  6. To ensure interoperability between content and software tools compliant with different profiles, SVGT is specified to be a proper subset of SVGB, and SVGB to be a proper subset of SVG 1.1.

2. Mobile SVG Document Types

SVGT and SVGB consist of the following SVG 1.1 modules. For each module, a given profile might contain the Full version, the subsetted Basic version, or no version of that module. For ease of use, the relevant elements in each module are given; in modules other than Full, not all attributes may be supported and there may be restrictions on attribute values. For details, see the module definitions in the SVG 1.1 specification.

3. Data Types

Data Type Description
Number SVGT and SVGB support fixed point numbers, thus all numbers must be limited in range between -32,767.9999 to +32,767.9999 or the scientific notation equivalent.
Length SVGT only supports user units (i.e., CSS units are not supported), with the one exception that the 'width' and 'height' attributes on the outermost 'svg' element can specify values in any of the following CSS units: in, cm, mm, pt, pc, and %. SVGB supports lengths in user coordinate space and in CSS units.
Coordinate SVGT and SVGB support the coordinate data type, represented with a <length> value.
List of XXX (where XXX represents a value of some type): SVGT and SVGB support the list specification.
Angle SVGT only supports angles if specified with no CSS unit identifiers (which means all angles are in degrees). SVGB supports angles with CSS unit identifiers.
Color SVGT and SVGB support <color> in the CSS2-compatible specification for a color in the sRGB color space, and system colors. Additionally, SVGB and SVGT support 16 original color keywords from XHTML, and do not support X11 colors. SVGB also allows optional support of ICC color profiles.
Paint SVGB supports paint specification for fill and stroke operations, as well as linear and radial gradients. SVGT does not support the more general notion of paint specification and thus only supports solid color fills and strokes.
Percentage SVGB supports percentages. SVGT does not support percentage values except for the 'width' and 'height' attributes on the outermost 'svg' element.
Transform List SVGB and SVGT support transform lists.
URI SVGB and SVGT support the URI datatype.
Frequency SVGB and SVGT do not support frequency values.
Time SVGB and SVGT support time values, with unit identifiers (ms, s).

4. Document Structure

Mobile SVG Document Fragment

SVGB and SVGT content can be in the form of stand-alone SVG Documents or document fragments embedded within a parent XML document. The following is an example of an SVG document fragment embedded within an XHTML 1.1 document:

  
      <?xml version="1.0" standalone="yes"?>
      <html xmlns="http://www.w3.org/1999/xhtml"
               xmlns:svg="http://www.w3.org/2000/svg">
      <head>
          <title xml:lang="en">Sample XHTML + SVG document</title>
      </head>
      <body>
         <svg:svg width="4cm" height="8cm" version="1.1" baseProfile="tiny" >
             <svg:ellipse cx="2" cy="4" rx="2" ry="1" />
         </svg:svg>
      </body>
      </html>

The 'title', 'desc', 'metadata' Elements

SVGB and SVGT support the 'title', 'desc' and 'metadata' elements as defined in SVG 1.1.

The 'svg' Element

SVG Tiny content cannot have nested child 'svg' elements.

The 'baseProfile' attribute on the outermost 'svg' element must have the value "tiny" for SVG Tiny content, and "basic" for SVG Basic content. The 'baseProfile' attribute on nested child 'svg' elements is ignored. The SVG 1.1 specification states that the 'version' attribute of the outermost 'svg' element in SVG 1.1 content must have the value "1.1".

References and the 'defs' Element

For SVGT, all referenced objects, except on the 'image' and 'a' elements, must be internal (using the 'data:' URL scheme, and base64 encoding). SVGB does not put extra limitations on external references as defined by SVG 1.1.

The 'symbol' Element

SVGT does not support symbols.

The 'use' Element

Note that, in SVG 1.1, animations on a referenced element will cause the instances to be animated. SVGB and SVGT also support this feature.

The 'image' Element

SVGB and SVGT require support of the JPEG and PNG formats on the image element. SVGB also requires support of SVG format on the image element.

The 'switch' Element

SVGT and SVGB support the switch element, to determine which SVG 1.1 features are supported by the user agent.

The following feature strings are allowed for SVGT:

The following feature strings are allowed for SVGB:

5. Styling

SVGB and SVGT support subsets of SVG 1.1's presentation attributes.

SVGB allows optional support of CSS Mobile Profile 1.0. SVGT does not support styling with CSS.

SVGB and SVGT can introduce constraints on style properties. Allowed values for style properties are listed in Appendix C.

6. Coordinate Systems, Transformations and Units

SVGB and SVGT support SVG 1.1's notion of viewports.

SVGB and SVGT support nesting of transformations. The types of transformations that are allowed are generic transformation matrices, or simple operations such as rotation, scaling, skewing, and translation.

The 'transform' Attribute

SVGB and SVGT support the transform attribute. The following transform definition types are supported:

The 'viewBox' Attribute

SVGB and SVGT fully support the 'viewBox' attribute. SVGT has restrictions on allowed preserveAspectRatio attribute values.

The 'preserveAspectRatio' Attribute

SVGB and SVGT support the 'preserveAspectRatio' attribute for adapting the content to devices with different display aspect ratios.

In SVGT,  the <align> parameter can only be either 'none' or 'XMidYMid', the <meetOrSlice> parameter can only be 'meet'.

In SVGB, the values of this parameter can be the same as in SVG 1.1.

Establishing a New Viewport

SVGB supports establishing a new viewport via additional embedded 'svg' elements. SVGT does not allow nested 'svg' elements.

Units

SVGT supports user units only, except for the 'width' and 'height' attributes on the outermost 'svg' element where CSS units are also supported. SVGB supports both user units and CSS user identifiers.

Object Bounding Box Units

SVGT does not support bounding box unit specification.

7. Shapes

Paths

SVGB and SVGT support all SVG 1.1 path commands, except the elliptical arc curve command ("A"(absolute) and "a"(relative)).

The path element data is animatable, as defined in the SVG 1.1 specification.

Basic Shapes

SVGT and SVGB support the basic shapes (rectangles, circles, ellipses, lines, polylines, and polygons) as defined in SVG 1.1.

8. Text

SVGB and SVGT represent text with Unicode characters. Mobile SVG user agents are not required to allow text selection and clipboard operations.

SVGT does not support text on a path, 'tspan' and 'tref' elements. SVGT supports the 'rotate' attribute on the 'text' element, but it should be noted that this may cause a slow down of the user agent's rendering speed, and rotation may not be supported with system fonts.

9. Painting: Filling, Stroking and Marker Symbols

SVGB and SVGT support filling and stroking 'path' elements and basic shapes with solid colors.

SVGB supports stroking on text when using outline fonts, but SVGT does not.

10. Color

SVGT and SVGB support <color> in the CSS2-compatible specification for a color in the sRGB color space, and system colors. Additionally, SVGB and SVGT support 16 original color keywords from XHTML, and do not support X11 colors.

Specifying colors using an ICC profile is not supported in SVGT; and as with SVG 1.1, it is optional in SVGB.

11. Gradients and Patterns

SVGB supports solid colors, gradient paints, patterns, and custom paints. SVGT only supports solid color painting.

12. Clipping, Masking and Compositing

SVGB supports clipping, masking and compositing. SVGB does not support additive clipping paths. Also, in SVGB, clipping paths are restricted to rectangles ('rect' elements or references to 'rect' elements through 'use').

SVGT does not support element opacity, fill-opacity, stroke-opacity properties.

13. Filter Effects

SVGB supports a subset of filter effects. SVGT does not support filter effects.

14. Interactivity

SVGB and SVGT support the SVG 1.1 events. SVGT only allows interactivity with declarative animation.

15. Linking

SVGB and SVGT support hyperlink activation from SVG content to other Web resources through the 'a' element.

SVGB supports hyperlink into particular views of SVG content. SVGT does not support this feature.

16. Scripting

SVGT does not support scripting. SVGB allows optional support of scripting, and includes all of the language features from SVG 1.1 to support scripting.

17. Animation

Both SVGB and SVGT support the full set of SVG 1.1's declarative animation features:

The language features to support animation through scripting and DOM are available in SVGB. SVGT only supports declarative animation.

SVGB and SVGT allow implicit targeting of parent elements, and targeting elements using the 'xlink:href' attribute.

SVGB and SVGT support linear, spline, paced and discrete animations.

18. Fonts

SVGB and SVGT support a subset of SVG fonts where only the 'd' attribute on the 'glyph' and 'missing-glyph' elements is available. Arbitrary SVG within a 'glyph' is not supported.

As with Full SVG 1.1, SVGB supports downloadable fonts using WebFonts facility defined in the "Cascading Style Sheets (CSS) level 2" specification. In SVGT, an SVG font can be only embedded within the same document that uses the font.

19. Metadata

Both SVGB and SVGT support embedded metadata, as well as elements and attributes from foreign namespaces included within the SVG content.

20. Extensibility

The SVG renderer is not expected to be able to render content in foreign namespaces, but the foreignObject element allows a subtree in a foreign namespace to be assigned a width and height and passed off to another renderer.

Acknowledgments

The SVG Working Group would like to acknowledge the great many people outside of the SVG Working Group who help with the process of developing the SVG 1.1 and Mobile SVG specification. These people are too numerous to list individually. They include but are not limited to the early implementers of the SVG 1.0 and 1.1 languages and Mobile SVG profiles (including viewers, authoring tools, and server-side transcoders), developers of SVG content, people who have contributed on the www-svg@w3.org and svg-developers@yahoogroups.com email lists, other Working Groups at the W3C, and the W3C team. Mobile SVG is truly a cooperative effort between the SVG Working Group, the rest of the W3C, and the public and benefits greatly from the pioneering work of early implementers and content developers, feedback from the public, and help from the W3C team.
