Hi Simon,
I'm afraid but there is no way to know on which page you are.
Is there a reason why you can't put the page number into a static area?
If you can then the following snippets might help:
1. Define your pages (left / right)
<fo:simple-page-master master-name="right_page"
page-height="{$MEDIA_PAGE_HEIGHT}cm" page-width="{$MEDIA_PAGE_WIDTH}cm"
margin-top="{$MEDIA_MARGIN_TOP}cm" margin-bottom="{$MEDIA_MARGIN_BOTTOM}cm"
margin-left="{$MEDIA_MARGIN_LEFT}cm" margin-right="{$MEDIA_MARGIN_RIGHT}cm">
<fo:region-body margin-top="{$SUBSIDIARIES_HEADER_EXTENT}cm"
margin-bottom="{$SUBSIDIARIES_FOOTER_EXTENT}cm"
margin-left="{$THUMB_AREA_EXTENT}cm" margin-right="{$THUMB_AREA_EXTENT}cm">
<xsl:call-template name="makeBackgroundImage"/>
</fo:region-body>
<fo:region-before
extent="{$SUBSIDIARIES_HEADER_EXTENT}cm"/>
<fo:region-after region-name="footer-even"
extent="{$SUBSIDIARIES_FOOTER_EXTENT}cm"/>
<fo:region-start extent="{$THUMB_AREA_EXTENT}cm"/>
<fo:region-end extent="{$THUMB_AREA_EXTENT}cm"/>
</fo:simple-page-master>
<fo:simple-page-master master-name="left_page"
page-height="{$MEDIA_PAGE_HEIGHT}cm" page-width="{$MEDIA_PAGE_WIDTH}cm"
margin-top="{$MEDIA_MARGIN_TOP}cm" margin-bottom="{$MEDIA_MARGIN_BOTTOM}cm"
margin-left="{$MEDIA_MARGIN_LEFT}cm" margin-right="{$MEDIA_MARGIN_RIGHT}cm">
<fo:region-body
margin-top="{$SUBSIDIARIES_HEADER_EXTENT}cm"
margin-bottom="{$SUBSIDIARIES_FOOTER_EXTENT}cm"
margin-left="{$THUMB_AREA_EXTENT}cm" margin-right="{$THUMB_AREA_EXTENT}cm">
<xsl:call-template name="makeBackgroundImage"/>
</fo:region-body>
<fo:region-before
extent="{$SUBSIDIARIES_HEADER_EXTENT}cm"/>
<fo:region-after region-name="footer-odd"
extent="{$SUBSIDIARIES_FOOTER_EXTENT}cm"/>
<fo:region-start extent="{$THUMB_AREA_EXTENT}cm"/>
<fo:region-end extent="{$THUMB_AREA_EXTENT}cm"/>
</fo:simple-page-master>
2. Assign them to odd / even page numbers
<fo:page-sequence-master master-name="subsidiaries">
<fo:repeatable-page-master-alternatives>
<fo:conditional-page-master-reference master-reference="right_page"
odd-or-even="odd"/>
<fo:conditional-page-master-reference master-reference="left_page"
odd-or-even="even"/> </fo:repeatable-page-master-alternatives>
</fo:page-sequence-master>
3. Use the page sequence and add layout specific to even / odd pages
<fo:page-sequence master-reference="subsidiaries">
<fo:static-content flow-name="footer-even">
<xsl:call-template name="makeNotesFootnote"/>
<xsl:call-template name="makePageNumberFooterEven"/>
</fo:static-content>
<fo:static-content flow-name="footer-odd">
<xsl:call-template name="makeNotesFootnote"/>
<xsl:call-template name="makePageNumberFooterOdd"/>
</fo:static-content>
<fo:flow>
...
</fo:flow>
</fo:page-sequence>
BTW: Please use fop-users list for questions like this in future.

Subject: Can't bind page number into a variable
Hi,
I would like to put specific attributes on odd or even pages, so I began
by looking for a way to check the context pages but I did'nt find
anything.
So I wanted to bind the <fo:page-number /> into a variable in order to
make some test on it when I want to add specific parameters to my tags.
<xsl:variable name="page_number"><fo:page-number /></xsl:variable>
<xsl:if test="($page_number mod 2)=1">
<xsl:attribute name="text-align">start</xsl:attribute>
</xsl:if>
<xsl:if test="($page_number mod 2)=0">
<xsl:attribute name="text-align">end</xsl:attribute>
</xsl:if>
But it looks like being impossible to bind the <fo:page-number /> into a
variable or param (I tried to write my variable in a block but it looks
like being setted to "" by the fo:page-number tag).
Is here a reason for my variable to be null ? And is there a way to detect
the context where I am currently in while writing in a non-static content
?
I also tried to make a template with a page_number param but it doesn't
work either...
Here are some examples of my pdf outputs :
http://www.tatouage.fr/temp/ap_skin_example.pdf
(here I want to align my titles at the start or the end of the block
depending of the odd or even condition, I am in a non-static context)
http://www.tatouage.fr/temp/cd_skin_example.pdf
(It's the same with this skin but it will be easier for me because every
objects have statical position on the page = I have one odd and one even
page for each XML <FICHE> tag, so I'll be able to manage the whole page
breaking in XSLT)
Sorry for disturbing you developpers with my little problem, but it makes
me so nervous ... :/
Thanks for your work on this API.
