XSL-FO + MathML

Render MathML to Display, PDF, SVG September 18 www.antennahouse.com

XSL-FO

•

Extensible Stylesheet Language (XSL) Version 1.0

W3C Recommendation 15 October 2001

http://www.w3.org/TR/2001/REC-xsl-20011015/

Version 1 was developed by W3C from 1998 to 2001 • The objective of XSL is to specify a layout of XML documents on paged media.

– 56 formatting objects – including 248 properties 2

MathML

• MathML is the XML-based language for mathematics • In 1997, the W3C's Math Working Group finished the MathML 1.0 Specification (superceded in 2001 by MathML 2.0 ) 3

XSL Formatter

• XSL Formatter is a software program, developed by Antenna House, to format XSL-FO. – One of the first commercial XSL-FO implementations.

– Released in 2001 – Has been enhanced continuously.

• Input data: XML/XSL-FO + Raster/Vector Graphics, SVG • Output data: PDF, Windows printer, Windows GUI, SVG (

under development, the function is not available with V3.2

) • Operating System – Windows2000/2003,XP, Linux, Solaris – AIX, Mac OS X (from V3.2 or later) 4

MathML option for XSL Formatter V3.2

• Developed by Antenna House • Renders MathML markup instance that is embedded within XSL-FO • It will be released as an optional function for XSL Formatter V3.2 and/or later. • Evaluation version is available from here: http://www.antennahouse.com

What will MathML option do?

• High quality rendering of XML for STM (Scientific, Technical, Medical) publishing using XSL-FO + MathML • XSL-FO + MathML will replace TeX in the future – TeX is popular, but it is not XML 6

MathML both for Web and PDF

• XML to XHTML – XML + MathML  XHTML + MathML • XML to PDF – XML + MathML  XSL-FO + MathML 7

MathML within XSL-FO

• How to specify MathML expression within XSL formatting object • MathML is treated as a vector Image – XSL-FO V1.0 specification only permits to embed foreign object via

fo:instream-foreign-object

and

fo:external-graphic

. 8

fo:instream-foreign-object

DTD declaration is necessary to use entity reference in MathML.

In case DTD is necessary: $...\; MathML\; including\; entity\; reference...$

]]> In case without DTD: $...\; MathML\; without\; entity\; reference...$

9

fo:external-graphic

• Specify URL of MathML file as the value of

src

property of

fo:external-graphic

object

Inline and Block

• Inline object: • Block object: object is treated like a character enclose

fo:instream-foreign-object

within

fo:block

Example Inline ...

Block

11

Interface

• MathML Renderer inherits following information from its environment: – font-size – font-family – font-weight – font-style – length of a 1px • XSL-FO processor gets following information from MathML renderer: – position of base-line 12

MathML Support Level

• Conformance to MathML 2.0 Specification • W3C MathML Test Suite result – V3.2 Beta version

Compatibility Issue

• Many tools are expected to be used throughout the world.

– MathML instances are generated by various tools, such as equation editors and/or converters.

• Compatibility between generator and renderer of MathML is very important – Correct MathML generation by various tools is a presupposition of automatic MathML rendering.
