Hi,
Using FOP 1.1 on Java 1.5
I have SVG images stored in a database (Oracle 11.2) which I want to include
in a PDF document.
To achieve that I've created a custom URIResolver listening to a specific
uri scheme, and used that uri as source for fo:external-graphics, e.g.
<xsl:template match="Object">
<fo:block>
<fo:external-graphic src="url('cache:/media/{@cache-id}')"
content-width="scale-to-fit" width="100%"/>
</fo:block>
</xsl:template>
While transforming and rendering the output document, the URIResolver then
issues the corresponding query against the db using the cache-id value and
returns a StreamSource. That works fine.
The "problem" is that the URIResolver (and therefore the db) is called twice
when building the PDF document : once when transforming my input XML into FO
and another time when rendering the PDF from the FO.
My question is : is that intended behaviour? Isn't the caching mechanism
supposed to work in this situation?
Just want to be sure.
When using a FO object directly (identity transformation), the URIResolver
is called only once.
Thanks for any pointers.
Marc.
