Antenna House: Issues with Ghostscript EPS Processor

[VDisplay911]

Hello,
I'm using Antenna House Formatter V7.2 and facing an issue where Ghostscript EPS processing corrupts the PDF tag structure and breaks accessibility features.

Problem:
When using

Code: Select all

eps-processor="ghostscript"

, the PDF output has two accessibility issues:
In Adobe Acrobat:

• ALT text does not appear on mouse hover over images

• In the Tags panel, images appear as corrupted tags named PathPathPathPath

Expected Behavior:

• ALT text for images should be displayed on mouse hover

• Image tags should show up correctly

In my ah_settings.xml file, I have the following code in my pdf-settings:

Code: Select all

eps-processor="ghostscript"
gs-add-options="-dCompatibilityLevel=1.6 
      -dPDFSETTINGS=/screen 
      -dEmbedAllFonts=true 
      -dSubsetFonts=true 
      -dColorImageDownsampleType=/Average 
      -dColorImageResolution=160 
      -dGrayImageDownsampleType=/Average 
      -dGrayImageResolution=160 
      -dMonoImageDownsampleType=/Average 
      -dMonoImageResolution=800"

The XML looks like this:

Code: Select all

<fig>
    <title>A sample figure EPS</title>
    <image href="sample-image.eps">
        <alt>Description of the EPS image</alt>
    </image>
</fig>

The generated FO looks like this:

Code: Select all

<fo:external-graphic 
    src="url('sample-image.eps')" 
    axf:alttext="Description of the EPS image"/>

What I've Tried:

Tags and ALT text work with the following options, but the image quality is poor.

• eps-processor="native"

• eps-processor="auto"

• eps-processor="distiller"

The Question:
What EPS processor configuration will make the ALT text and tags appear correctly while preserving good image quality?

Any help is appreciated.

Hi,
This is a forum intended mostly for Oxygen XML Editor questions, we (the Oxygen team) do not know the inner workings and features of Antenna House, maybe you can contact Antenna House and ask for help on this. If you do not have a POC I can try to reach out to my contact at Antenna House and ask him to reply to you on our forum.

Hi,

The advice I got from my Antenna House contact is:

It would still be better if they could contact support@antennahouse.com and provide their actual files.
