Abstract

This document defines two mobile profiles of SVG 1.1. The first profile, SVG Tiny, is defined to be suitable for cellphones; the second profile, SVG Basic, is suitable for PDAs.

Status of this document

This specification from the W3C SVG Working Group is a Candidate Recommendation of the W3C. The Working Group believes this specification incorporates the resolution of all Last Call issues; furthermore it considers the specification to be stable and invites implementation feedback during this period.

The exit criteria for this phase is at least two implementations of every feature, one of which operates on the intended target platform for that profile. Additionally, should there be multiple implementations of all of the features on the intended target platform yet no single implementation that covers all of a profile of this specification in one viewer, then the Working Group must be satisfied that this is a reasonably achievable goal.

W3C SVG Working Group expects to meet implementations that meet all requirements of this document within the two month Candidate Recommendation period (closing at 1159Z on 23 June 2002). Specific areas where we would appreciate further experience are:

• Do implementations satisfy target device requirements?
• Do implementations achieve satisfactory performance?
• Does the specification satisfy application scenario requirements?

This document has been produced by the W3C SVG Working Group as part of the Graphics Activity within the W3C Document Formats Domain. The goals of the W3C SVG Working Group are discussed in the W3C SVG charter (W3C Members only). The W3C SVG Working Group has maintained a public Web page http://www.w3.org/Graphics/SVG/ which contains further background information. The authors of this document are the SVG Working Group participants.

We explicitly invite comments on this document. Please send them to svg-comments@w3.org. Public discussion of issues related to vector graphics on the Web and SVG in particular takes place on the public mailing list of the SVG Working Group (list archives). To subscribe send an email to www-svg-request@w3.org with the word subscribe in the subject line.

A list of current W3C Recommendations and other technical documents can be found at http://www.w3.org/TR/. W3C publications may be updated, replaced, or obsoleted by other documents at any time.

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

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

Attributes of 'svg' elements that appear in the middle of SVGT content cannot be specified in CSS unit identifiers.

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', 'font-face-uri', 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 Working Group invites implementation feedback on whether external references and base64 encoding are desirable or implementable on SVGT devices.

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, PNG, and SVG formats 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:

5. Styling

SVGB and SVGT support subsets of SVG 1.1's presentation attributes. SVGB and SVGT allow optional support of CSS Mobile Profile 1.0.

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:

• Matrix(<a><b><c><d><e><f>)
• Translate(<tx>[<ty>])
• Scale(<sx>[<sy>])
• Rotate(<rotate_angle>[<cx><cy>])
• SkewX(<skew_angle>)
• SkewY(<skew_angle>)

The 'viewBox' Attribute

SVGB and SVGT fully support the 'viewBox' attribute, however with restrictions on 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 and SVGT support establishing a new viewport via additional embedded '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

SVGB and SVGT support colors defined by 'color' property in sRGB color space, and color keywords.

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.

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

SVGB and SVGT include all of the language features from SVG 1.1 to support scripting. Scripting is optional in SVGB and SVGT. SVG Tiny does not require a default language that has to be supported by all user agents.

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 and SVGT.

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, SVGT and SVGB support downloadable fonts using WebFonts facility defined in the "Cascading Style Sheets (CSS) level 2" specification.

The SVG Working Group invites implementation feedback on whether the downloadable fonts are desirable or implementable on SVGT devices.

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.

Appendix F. Conformance Criteria

This section describes conformance criteria for SVG Tiny and SVG Basic Document Fragments and User Agents. These criteria take SVG 1.1 conformance criteria as a base, and add or relax restrictions.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].

F.1. SVG Tiny Conformance Criteria

Fragment Conformance

A conforming SVG Tiny document fragment is a document fragment that requires only the facilities described as mandatory in this specification. Such a document fragment MUST meet all the following criteria:

• The document fragment MUST conform to the constraints defined in Appendix D.
• The root of the document fragment MUST be <svg>, its version attribute MUST be "1.1", and its baseProfile attribute MUST be "tiny".
• The name of the namespace MUST be the SVG namespace name, http://www.w3.org/2000/svg.
• There SHOULD be a DOCTYPE declaration which points to the modules supported in SVG Tiny. For example:

  <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG Tiny 1.1//EN"
  http://www.w3.org/Graphics/SVG/1.1/DTD/svg11-tiny.dtd>
    

User Agent Conformance

A conforming SVG Tiny User Agent is a User Agent that requires only the facilities described as mandatory in this specification. Such a User Agent MUST meet all the following criteria:

• Conforming SVGT UAs MUST be able to parse and process the base SVGT language features that correspond to the feature string "http://www.w3.org/TR/SVGMobile/Tiny/Feature#base".
• In addition to the requirements for the static category, Conforming Dynamic SVGT UAs MUST be able to parse and process the language features of SVGT that correspond to the feature string "http://www.w3.org/TR/SVGMobile/Tiny/Feature#interactivity" and which support all of the required features for SVGT subset of DOM described in the SVG 1.1 specification.
• For interactive user environments, facilities SHOULD exist for zooming and panning of stand-alone SVGT documents or SVGT document fragments embedded within parent XML documents.
• The viewer MAY support alpha channel blending of the image of the SVG content onto the target canvas.
• If the implementation supports progressive rendering, the implementation MAY also support progressive rendering of compressed data streams.
• All visual rendering SHOULD be accurate to within one device pixel to the mathematically correct result.
• On systems which support accurate sRGB [SRGB] color, all sRGB color computations and all resulting color values SHOULD be accurate to within one sRGB color component value, where sRGB color component values range from 0 to 255.

Dynamic SVGT User Agent Conformance

Specific criteria that apply for only Conforming Dynamic SVGT Viewers:.

• The viewer MAY have the ability to search and select text strings within SVG content.
• If display devices are supported, the viewer MAY have the ability to select and copy text from SVG content to the system clipboard.
• The viewer MAY have complete support for script binding of the SVG Tiny subset of SVG Document Object Model. The default script language is not defined.
• If the user agent includes a CSS2 capability, a Conforming SVG Viewer SHOULD support CSS styling of SVG content and SHOULD support all features from CSS Mobile Profile.

SVGT User Agent Compatibility Issues

Specific criteria that apply for behavior when SVGT User Agents encounter elements and attributes that are not recognized, and other compatibility issues:

• The SVGT UAs MUST render SVG content with version attribute set to "1.1" and baseProfile attribute set to "tiny".
• SVGT UAs SHOULD notify the user when it encounters content with outermost 'svg' element with 'version' attribute not set to "1.1" or 'baseProfile' not set to "tiny".
• SVGT UAs SHOULD notify the user when it encounters content which includes elements or attributes in SVG namespace, but not in SVGT profile.
• When rendering content, SVGT UAs that encounter characters or character entity references that are recognized but not renderable should display the document in such a way that it is obvious to the user that normal rendering has not taken place.
• If an SVGT UA encounters an attribute value it does not recognize, it MUST use the default attribute value.
• SVGT UAs MUST ignore elements with attributes of a Basic Data Type, which is defined using CSS units, except for outermost 'svg' elements (e.g. x attribute of 'rect' element)
• As of the publication of this recommendation, the general recommended MIME labeling for SVG Tiny content is the same as SVG 1.1: image/svg+xml. The SVG Working Group is considering recommending to include a profile parameter on the Media Type for content negotiation purposes. The Working Group invites feedback on this issue.

F.2. SVG Basic Conformance Criteria

Document Fragment Conformance

A conforming SVG Basic document fragment is a document fragment that requires only the facilities described as mandatory in this specification. Such a document fragment MUST meet all the following criteria:

• The document fragment MUST conform to the constraints defined in Appendix E.
• The root of the document fragment MUST be <svg>, its version attribute MUST be "1.1", and its baseProfile attribute MUST be "basic".
• The name of the namespace MUST be the SVG namespace name, http://www.w3.org/2000/svg.
• There SHOULD be a DOCTYPE declaration which points to the modules supported in SVG Basic. For example:

  <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG Basic 1.1//EN"
  http://www.w3.org/Graphics/SVG/1.1/DTD/svg-basic11.dtd>
    

User Agent Conformance

A conforming SVG Basic User Agent is a User Agent that requires only the facilities described as mandatory in this specification. Such a User Agent MUST meet all the following criteria:

• Conforming SVGB UAs MUST be able to parse and process the base SVGT and SVGB language features that correspond to the feature strings "http://www.w3.org/TR/SVGMobile/Tiny/Feature#base" and "http://www.w3.org/TR/SVGMobile/Basic/Feature#base".
• In addition to the requirements for the static category, Conforming Dynamic SVGB UAs MUST be able to parse and process the language features of SVGB and SVGT that correspond to the feature strings "http://www.w3.org/TR/SVGMobile/Tiny/Feature#interactivity" and "http://www.w3.org/TR/SVGMobile/Basic/Feature#interactivity" and which support all of the required features for SVGB subset of DOM described in the SVG 1.1 specification.
• For interactive user environments, facilities SHOULD exist for zooming and panning of stand-alone SVGB documents or SVGB document fragments embedded within parent XML documents.
• If the implementation supports progressive rendering, the implementation MAY also support progressive rendering of compressed data streams.
• All visual rendering SHOULD be accurate to within one device pixel to the mathematically correct result.
• On systems which support accurate sRGB [SRGB] color, all sRGB color computations and all resulting color values SHOULD be accurate to within one sRGB color component value, where sRGB color component values range from 0 to 255.

Dynamic SVG Basic User Agent Conformance

Specific criteria that apply for only Conforming Dynamic SVGB Viewers:.

• The viewer SHOULD have the ability to search and select text strings within SVG content.
• If display devices are supported, the viewer SHOULD have the ability to select and copy text from SVG content to the system clipboard.
• The viewer MAY have complete support for script binding of the SVGB subset of SVG Document Object Model. The default script language is not defined.
• If the user agent includes a CSS2 capability, a Conforming SVG Viewer SHOULD support CSS styling of SVG content and SHOULD support all features from CSS Mobile Profile.

SVG Basic User Agent Compatibility Issues

Specific criteria that apply for behavior when SVGB UAs encounter elements and attributes that are not recognized, and other compatibility issues:

• The SVGB UAs MUST render SVG content with version attribute set to "1.1" and baseProfile attribute set to "basic" or "tiny".
• SVGB UAs SHOULD notify the user when it encounters content with outermost 'svg' element with 'version' attribute not set to "1.1" or 'baseProfile' not set to "basic" or "tiny".
• SVGB UAs SHOULD notify the user when it encounters content which includes elements or attributes in SVG namespace, but not in SVGB profile.
• When rendering content, UAs that encounter characters or character entity references that are recognized but not renderable should display the document in such a way that it is obvious to the user that normal rendering has not taken place.
• If an SVGB UA encounters an attribute value it does not recognize, it MUST use the default attribute value.
