equation-figure@expanse="page" has no observed effect in pdf5-ml and other pdf transformations

[Andy Hall]

 

Hi all,

 

I expect this is a query that Makita-san can likely address but this may be more broadly applicable.

 

I am testing the use of a large (wide) MathML equation with the pdf5-ml transformation.

 

I have a trial license of AH Formatter 6.6.

I am using DITA OT 3.3.3.

 

 

When I set the equation-figure attribute expanse to "page", I observe no effect. As a result, the wide equation from exceeding the margins and right edge of the page (Letter size page).

 

I am also using the scale attribute and that has some effect but 50 is the lower limit of the scale attribute value and I cannot scale the equation down too much for legibility reasons.

 

I realize that my test equation does not *need* to be as wide as it as and could be broken up for the sake of display. That break-up work may be necessary. But if we can address this shortcoming in the pdf5-ml transformation, it would be a great help and the behavior would then correspond with the specification.

 

 

Reference: https://docs.oasis-open.org/dita/dita/v1.3/os/part1-base/langRef/attributes/displayAttributes.html

expanse="page"

Places the element on the left page margin for left-to-right presentation, or right page margin for right-to-left presentation.

 

Based on what I observe currently, the equation-figure@expanse="page" has no effect for the pdf5-ml transformation. In defense of pdf5-ml, equation-figure@expanse="page" appears to have no impact on the FOP PDF transform nor the transform "DITA Map PDF - based on HTML5 & CSS".

 

I am happy to share the equation-figure and MathML.

 

Should I create an issue?

Does anyone else have suggestions?

Thanks in advance,

Andy Hall

Hi Andy,

If you have not the account of GitHub, please send your sample data to Antenna House support.

I am planning next release of PDF5-ML plug-in within September and I want to include your request in this release.
