[xep-support] Calculating left-indent

[Alexander Peshkov]

Hello David,

There are no means in XSL-FO to dynamically determine current distance
from the page edge and perform any calculations with it. However there
are 'text-align' property and 'float' property which both can have
value of 'inside' and 'outside'. That is any text can be aligned with
respect to the current page position (parity) and floating object can
be forced to float to the outer or inner side of the page.
You may be interested in 'Marginalia' sample available on our site:
http://xep.xattic.com/xep/testsuite/usecasestest.html#marginalia 
This sample shows how to create marks on the margins (known as
'marginalia') using side floats with float='outside'.

Hope this helps.

Best regards,
Alexander Peshkov                             mailto:peshkov at renderx.com

DP> Is there an easy method of dynamically determining the distance from the

DP> I think the calculation would include page.margin-left and  
DP> region-body.margin-left.  I don't think region-start would be needed, as  
DP> region-body needs to set a left margin that doesn't overwrite it.  One

DP> for the current content block.

DP> Alternatively, simply knowing whether my template was currently putting

DP> Any hints would be greatly appreciated.  The solution can be XEP-specific.
