Is there a recommended way to process images differently in pdfs and
webhelp output from from ditac?
What I’d like to achieve is that all images are 100% in webhelp, but in
pdfs most are 60%, but some (icons for example) remain at 100%.
I’ve used the scalefit attribute set to Yes, and this gives a good
result in pdfs, but not in webhelp.
Probably the simplest solution is to be able to override scalefit when
converting to webhelp.
I don't know the recommended way. I can just explain what I do in my own
DITA documents.
In my own DITA documents, I want to use SVG images when I generate PDF,
DOCX, etc, and to use PNG images when I generate HTML, Web Help, etc.
1) I add the same image twice in the DITA topic, one time in SVG format
and another time in PNG format.

<fig frame="all" id="page_areas">
<title>Page areas</title>
<image align="center" href="images/page_areas.svg"
otherprops="svg=yes" width="15cm"/>
<image align="center" href="images/page_areas.png"
otherprops="svg=no"/>
</fig>

Also notice the different values for the "otherprops" conditional
processing attribute.
2) I've created these 2 .ditaval files:
svg.ditaval
---
<val>
<prop action="exclude" att="otherprops" val="svg=no"/>
</val>
---
no_svg.ditaval
---
<val>
<prop action="exclude" att="otherprops" val="svg=yes"/>
</val>
---
3) I generate the PDF as follows:
ditac -filter svg.ditaval out/manual.pdf manual.ditamap
I generate the WebHelp as follows:
ditac -filter no_svg.ditaval -format webhelp5 out/wh/_.html manual.ditamap
