Subject: Re: [docbook-apps] Centering chapter titles with fop

So, I repost my answer to Gian's questions from December 7th (a long one)- Let me know if you want all the documents, I'll post them on my web site.: Actually I discover that this is not the same for chapter, preface and appendix. This a book with multiple files, double-sided . There is a customization of titlepage-template, mainly to reduce the space before and after: A - For preface: <t:titlepage t:element="preface" t:wrapper="fo:block"> <t:titlepage-content t:side="recto"> <title t:force="1" t:named-template="component.title" param:node="ancestor-or-self::preface[1]" margin-left="{$title.margin.left}" font-size="&hsize5;" font-family="{$title.fontset}" font-weight="bold" text-align="center" start-indent="0pt" space-before.minimum="0em" space-before.optimum="0em" space-before.maximum="0em" space-after="0em"/> B - For Appendix <t:titlepage t:element="appendix" t:wrapper="fo:block"> <t:titlepage-content t:side="recto"> <title t:named-template="component.title" param:node="ancestor-or-self::appendix[1]" margin-left="{$title.margin.left}" font-size="&hsize4;" font-weight="bold" text-align="center" space-before.minimum="0em" space-before.optimum="0em" space-before.maximum="0em" font-family="{$title.fontset}"/> (Notice the lack of start-indent="0pt" here, a mistake from my part). Without it, Appendix is not centered, in both versions of stylesheet, with it, it is centered in 1.68.1 only. C - For Chapter <t:titlepage t:element="chapter" t:wrapper="fo:block" font-family="{$title.fontset}"> <t:titlepage-content t:side="recto" margin- left="{$title.margin.left}"> <title t:named-template="component.title" param:node="ancestor-or-self::chapter[1]" font-size="&hsize5;" font-weight="bold" text-align="center" start-indent="0pt" space-before.minimum="0em" space-before.optimum="0em" space-before.maximum="0em" space-after="0em"/> There is also a custom layer: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"> <xsl:import href="http://docbook.sourceforge.net/release/xsl/current/ fo/docbook.xsl"/> (Actually this is resolved locally to 1.68.1 or 1.69.1 depending of which version I install) <xsl:import href="titlepage-a4.xsl"/> <!-- Allow to use extensions --> <xsl:param name="use.extensions" select="'1'"></xsl:param> <!-- For bookmarks --> <xsl:param name="fop.extensions" select="1"></xsl:param> <!-- Ensure the page orientation is portrait --> <xsl:param name="page.orientation" select="portrait"></xsl:param> <!-- A4 format --> <xsl:param name="paper.type" select="'A4'"></xsl:param> <xsl:param name="page.width" select="'210mm'"></xsl:param> <xsl:param name="page.height" select="'297mm'"></xsl:param> <!-- Double-sided --> <xsl:param name="double.sided" select="1"></xsl:param> <!-- Margins --> <xsl:param name="page.margin.top" select="'7.5mm'"></xsl:param> <xsl:param name="page.margin.bottom" select="'7.5mm'"></xsl:param> <xsl:param name="region.before.extent" select="'5mm'"></xsl:param> <xsl:param name="region.after.extent" select="'5mm'"></xsl:param> <xsl:param name="body.margin.top" select="'10mm'"></xsl:param> <xsl:param name="body.margin.bottom" select="'10mm'"></xsl:param> <xsl:param name="page.margin.inner" select="'15mm'"></xsl:param> <xsl:param name="page.margin.outer" select="'12mm'"></xsl:param> <!-- No headers on blank pages --> <xsl:param name="headers.on.blank.pages" select="0"></xsl:param> <!-- Indentation of the titles for sections --> <xsl:param name="title.margin.left" select="'-1pc'"/> <!-- Chapter autolabelling --> <xsl:param name="chapter.autolabel" select="'I'"/> <!-- Section autolabelling --> <xsl:param name="section.autolabel" select="'1'"/> <!-- Size of body font --> <xsl:param name="body.font.master">10</xsl:param> <xsl:param name="body.font.size"> <xsl:value-of select="$body.font.master"/><xsl:text>pt</xsl:text> </xsl:param> <!-- Prohibites hyphenation --> <xsl:param name="hyphenate">false</xsl:param> ... </xsl:stylesheet> > > 2.)

They > should be different, because as you say the former works but the > latter doesn't. > I've redone the production of pdf with exactly the same customized stylesheets for 1.68.1 and 1.69.1, because actually there were differences in the versions (keep-with-next for 1.68.1 and keep-with- next-within-columns for 1.69.1 in official template) and also a difference in start-indent in appendix or chapter. So, now preface, chapters are centered in 1.68.1 but not appendix (unless I put start-indent="0pt" as stated above); None are centered in 1.69.1. I - Here are the differences for appendix: a - Appendix not centered in 1.68.1 (lack of start-indent="0pt) <fo:flow flow-name="xsl-region-body" start-indent="4pc" end-indent="0pt"> <fo:block id="bluefish-appb"> <fo:block> <fo:block> <fo:block margin-left="-1pc" font-size="20.736pt" font-weight="bold" space-before.minimum="0em" space-before.optimum="0em" space-before.maximum="0em" font-family="sans-serif,Symbol,ZapfDingbats"> <fo:block keep-with-next.within-column="always" space-before.optimum="10pt" space-before.minimum="10pt * 0.8" space-before.maximum="10pt * 1.2" hyphenate="false" start-indent="0pt" hyphenation-character="-" hyphenation-push-character-count="2" hyphenation-remain-character-count="2">Appendix B. Bluefish change history</fo:block> </fo:block> </fo:block> </fo:block> </fo:block> b - Appendix centered in 1.68.1 (with start-indent="0pt") <fo:flow flow-name="xsl-region-body" start-indent="4pc" end-indent="0pt"> <fo:block id="bluefish-appa"> <fo:block> <fo:block> <fo:block margin-left="-1pc" font-size="20.736pt" font-weight="bold" text-align="center" (change here) start-indent="0pt" (change here) space-before.minimum="0em" space-before.optimum="0em" space-before.maximum="0em" font-family="sans-serif,Symbol,ZapfDingbats"> <fo:block keep-with-next.within-column="always" space-before.optimum="10pt" space-before.minimum="10pt * 0.8" space-before.maximum="10pt * 1.2" hyphenate="false" start-indent="0pt" hyphenation-character="-" hyphenation-push-character-count="2" hyphenation-remain-character-count="2">Appendix A. Credits<fo:block> </fo:block> </fo:block> </fo:block> </fo:block> Notice the integration of text-align and start-indent in the first fo:block. c - Appendix not centered on 1.69.1 (without start-indent) <fo:flow flow-name="xsl-region-body"> (change here) <fo:block id="bluefish-appb"> <fo:block> <fo:block> <fo:block margin-left="-1pc" font-size="20.736pt" font-weight="bold" space-before.minimum="0em" space-before.optimum="0em" space-before.maximum="0em" font-family="sans-serif,Symbol,ZapfDingbats"> <fo:block keep-with-next.within-column="always" space-before.optimum="10pt" space-before.minimum="10pt * 0.8" space-before.maximum="10pt * 1.2" hyphenate="false" text-align="left" (change here) start-indent="-1pc" (change here) hyphenation-character="-" hyphenation-push-character-count="2" hyphenation-remain-character-count="2">Appendix B. Bluefish change history</fo:block></fo:block> </fo:block> </fo:block> </fo:block> So, basically, two changes: one for the pc thing, and a text- align="left" introduced in 1.69.1 (I cannot understand where it comes from). d - Appendix not centered on 1.69.1 (with start-indent- <fo:flow flow-name="xsl-region-body"> (change here- <fo:block id="bluefish-appa"> <fo:block> <fo:block> <fo:block margin-left="-1pc" font-size="20.736pt" font-weight="bold" text-align="center" start-indent="0pt" space-before.minimum="0em" space-before.optimum="0em" space-before.maximum="0em" font-family="sans-serif,Symbol,ZapfDingbats"> <fo:block keep-with-next.within-column="always" space-before.optimum="10pt" space-before.minimum="10pt * 0.8" space-before.maximum="10pt * 1.2" hyphenate="false" text-align="left" (change here) start-indent="-1pc" (change here) hyphenation-character="-" hyphenation-push-character-count="2" hyphenation-remain-character-count="2">Appendix A. Credits</fo:block> </fo:block> </fo:block> </fo:block> </fo:block> It seems that 1.69.1 overrides whichever change is made to alignement and start-indent with what is defined for title-margin-left. (i.e. no distinction between chapter, preface, appendix and section titles). II - chapter: a - Chapter centered on 1.68.1 <fo:flow flow-name="xsl-region-body" start-indent="4pc" end-indent="0pt"> <fo:block id="debugging-bluefish"> <fo:block font-family="sans-serif,Symbol,ZapfDingbats"> <fo:block margin-left="-1pc"> <fo:block font-size="24.8832pt" font-weight="bold" text-align="center" space-before.minimum="0em" space-before.optimum="0em" space-before.maximum="0em" space-after="0em"> <fo:block keep-with-next.within-column="always" space-before.optimum="10pt" space-before.minimum="10pt * 0.8" space-before.maximum="10pt * 1.2" hyphenate="false" start-indent="0pt" hyphenation-character="-" hyphenation-push-character-count="2" hyphenation-remain-character-count="2">Chapter 4. Debugging Bluefish</fo:block> </fo:block> </fo:block> </fo:block> </fo:block> b - Chapter not centered on 1.69.1 <fo:flow flow-name="xsl-region-body"> (change here) <fo:block id="debugging-bluefish"> <fo:block font-family="sans-serif,Symbol,ZapfDingbats"> <fo:block margin-left="-1pc"> <fo:block font-size="24.8832pt" font-weight="bold" text-align="center" space-before.minimum="0em" space-before.optimum="0em" space-before.maximum="0em" space-after="0em"> <fo:block keep-with-next.within-column="always" space-before.optimum="10pt" space-before.minimum="10pt * 0.8" space-before.maximum="10pt * 1.2" hyphenate="false" text-align="left" (change here) start-indent="-1pc" (change here) hyphenation-character="-" hyphenation-push-character-count="2" hyphenation-remain-character-count="2">Chapter IV. Debugging Bluefish</fo:block> </fo:block> </fo:block> </fo:block> </fo:block> So, there changes: two related to pc, and the same text-align="left" introduced.
