Subject: Re: [docbook-apps] svg figure role
I feel dumb. I had set use.role.for.mediaobject to zero a while back. This was before I figured out that I didn't need to be so strict with the way I was profiling everything and before I figured out that profile.condition is what I should have been using for profiling in most cases that aren't covered by the default operation of the stylesheets. Now, in the xhtml case, the output includes, which produces no image in Firefox. <img src="Gravimetric_and_Gasometric_Determination_of_Zinc/Vacuum_Flask.svg" alt="Vacuum Flask"/> If I manually change the xhtml to read <object data="Gravimetric_and_Gasometric_Determination_of_Zinc/Vacuum_Flask.svg" type="image/svg+xml"/> the svg shows up. It turns out that setting the attribute format="SVG" on the imagedata tag does this modification, which must be what Bob Stayton is referring to in his guide at http://www.sagehill.net/docbookxsl/SVGimages.html when he says, "Be sure to include the format="SVG" attribute to ensure the file is handled properly." I am wondering, is there a technical reason why outputting an object tag requires a format attribute on the imagedata tag instead of being able to guess the format from the fileref attribute? Again, thanks to Bob S. for his help (and awesome style sheet programming) - I have no idea how long it would have taken me to discover the parameter that was causing this behavior if he hadn't mentioned it by name.
