3 XSL-FO Aims to describe high-quality output prints.

4 XSL-FO Aims to describe high-quality output prints. In fact: dsssl xsl xslt xsl(-fo)

5 XSL-FO Aims to describe high-quality output prints. In fact: dsssl xsl xslt xsl(-fo) Very verbose language. 3

6 xml text Using XSL-FO

7 xml text xslt = xsl-fo Using XSL-FO

8 Using XSL-FO xml text xslt = xsl-fo fo processor = pdf, ps, etc.

9 Using XSL-FO xml text xslt = xsl-fo fo processor = pdf, ps, etc. Automatically chained by complete fo processors.

10 Using XSL-FO xml text xslt = xsl-fo fo processor = pdf, ps, etc. Automatically chained by complete fo processors. Not wisiwyg. 4

11 FO processors Free of charge: the best the most complete Apache fop.

12 FO processors Free of charge: the best the most complete Apache fop. Related to TEX s world: PassiveTEX

13 FO processors Free of charge: the best the most complete Apache fop. Related to TEX s world: PassiveTEX = stalled. 5

14 L A TEX = XSL-FO EuroBachoTEX, April 2007.

15 L A TEX = XSL-FO EuroBachoTEX, April GUTenberg, October 2008.

16 L A TEX = XSL-FO EuroBachoTEX, April GUTenberg, October Multidirectional typesetting in xsl-fo. April BachoTEX,

17 L A TEX = XSL-FO EuroBachoTEX, April GUTenberg, October Multidirectional typesetting in xsl-fo. April BachoTEX, Italian translation updated, by Massimiliano Dominici. 6

18 General principles Same ideas than (LA )TE X, but the markup is more homogeneous.

19 General principles Same ideas than (LA )TE X, but the markup is more homogeneous. L A TEX: {\em...} \emph{...} \begin{emph}...\end{emph}

20 General principles Same ideas than (LA )TE X, but the markup is more homogeneous. L A TEX: {\em...} \emph{...} \begin{emph}...\end{emph} xsl-fo = \begin{emph}...\end{emph}. 7

21 ...\par Basic elements

22 Basic elements...\par <fo:block>...</fo:block>

23 Basic elements...\par <fo:block>...</fo:block> \begin{minipage}{...}...\end{minipage} 8

24 Containers fo:block fo:inline...

25 Containers fo:block fo:inline... If an attribute is not redefined, it is inherited: <fo:block font-family="sans-serif" font-size="medium"> You re afraid, <fo:inline font-size="large">ain t</fo:inline> you? </fo:block> 9

26 Rubber lengths = interactions space-before space-after

27 Rubber lengths = interactions space-before space-after Components: space-before="..." space-before.minimum="..." space-before.optimum="..." space-before.maximum="..." 10

28 Solving conflicts Beginning or ending a reference = conditionality (discard retain). Between two reference areas = precedence (integer force). 11

29 More about interactions keep-with-next="always" or an integer, keep-with-next.within-line keep-with-next.within-page keep-with-previous... keep-together... 12

30 Other elements Close to L A TEX s commands: fo:footnote fo:float

31 Other elements Close to L A TEX s commands: fo:footnote fo:float Closer to (x)html: fo:list-block fo:table

32 Other elements Close to L A TEX s commands: fo:footnote fo:float Closer to (x)html: fo:list-block fo:table Interactions about such elements. 13

33 Multilingual capabilities Word hyphenation w.r.t. a language. Partly implemented, but specified in the w3c recommendation. (See examples.) 14

34 Page model document classes in L A TEX.

35 Page model document classes in L A TEX. fo:region-body, fo:region-before, fo:region-after, fo:region-start, fo:region-end.

36 Page model document classes in L A TEX. fo:region-body, fo:region-before, fo:region-after, fo:region-start, fo:region-end. Headers and footers = static content.

37 Page model document classes in L A TEX. fo:region-body, fo:region-before, fo:region-after, fo:region-start, fo:region-end. Headers and footers = static content. Text for successive pages = flow. 15

38 Page model s regions region-before margin-top margin-left region-start region-body region-end margin-right region-after margin-bottom 16

52 Conclusion fo processors = not L A TEX.

53 Conclusion fo processors = not L A TEX. My personal point of view: (LA)T E X and xsl-fo should converge. 25
