$mediaobject-percentage-of-intrinsic-size — Compute media object percentage sizes based on intrinsic size.
Synopsis
$mediaobject-percentage-of-intrinsic-size as xs:string := 'false'Description
When the width or depth of a media object is specified as a percentage,
it is supposed to be a percentage of the available space. All versions of
the DocBook xslTNG Stylesheets before version 2.7.0
incorrectly calculate percentages against the intrinsic size of the
image.
This has been corrected in 2.7.0, but the previous, incorrect behavior
can be preserved by setting $mediaobject-percentage-of-intrinsic-size
to true.
Percentages are problematic in any event as the stylesheets don’t usually know the
actual width that will be available when the document is formatted. Most often, this
results in a calculation against the $image-nominal-height and
$image-nominal-width.
