Image Map PDF output

[namita]

Hi Radu (assuming this goes to you),

I finally have Oxygen 19 with me and the feature is working superbly. I want to create a PDF with working image map. The Preview XHTML output works perfectly, but when I generate the PDF output, I can see only the image without the active hotspot links. Note, the XREFs in the body work perfectly, just the hyperlinks (hotspots) created through Image Map are missing. Is there any specific way to generate a PDF output for a DITA file having an Image Map?

Hi Namita,

Right now the default PDF output for DITA does not show hotspots for image maps:

As sometimes the PDF is intended for print this is a feature which may not be implemented.

Thank you very much for the clarification, Radu!

Hi,

In PDFs, the descriptions and links of image map hotspots are displayed as a numbered list below the image.
Is there a way to suppress this and display nothing?

Thanks,
Anne

Hi Anne,

There is no setting for this, the XSLT stylesheet "OXYGEN_INSTALL_DIR/frameworks/dita/DITA-OT3.x/plugins/org.dita.pdf2/xsl/fo/ut-domain.xsl" has a template which matches the ut-d/imagemap and outputs the image and the list after it. Probably with a PDF customization plugin or folder you can override this template.
Or you can specify on each <area> element a deliveryTarget attribute:

Code: Select all

<area deliveryTarget="html">....

and have a DITAVAL filter file specifically for PDF which excludes elements based on that particular delivery target value.

Hi Radu,

Thanks for your response. I thought about profiling with deliveryTarget. But it is not recognized by the system automatically, and profiling needs to be done as with any other custom profiling attribute, right?
How can this be done with a PDF customization plugin?

Hi Radu,

Now a plugin is available here to manage imagemap element in PDF with SVG : https://www.dita-ot.org/plugins#!com.am ... agemap-pdf

Hi Nicolas,

This sounds great, I will take a look at it. Thanks for updating the forum thread.

Hi Radu,
Almost 2 years passed, is there any update?
The plugin seems to give issues with Fop 2.4, interested to see whether also with newer Fop versions...

Hi,

If you publish DITA to PDF using our "DITA Map PDF - based on HTML5 & CSS" transformation scenario which uses our Chemistry engine to style the content using CSS, the image maps support should already work: https://www.oxygenxml.com/doc/versions/ ... mages.html
If you publish DITA to PDF using the XSL-FO based approach I'm afraid we do not have another solution for you, our main future improvement direction is the CSS-based PDF publishing.

Radu
