 Description  « Hide
When "forresting" a document that has embedded images, the PDF rendering sometimes stops with this error message:

BROKEN: org.apache.fop.apps.FOPException: No meaningful layout in block after many attempts. Infinite loop is assumed. Processing halted.

I've found that this is caused by images that are too big to fit in the PDF page (took me some times :) )

(Moved workaround from Description to Comment - see 2005-12-24)

Description When "forresting" a document that has embedded images, the PDF rendering sometimes stops with this error message:

I've found that this is caused by images that are too big to fit in the PDF page (took me some times :) )
I temporary "solved" it by modifying the document2fo.xsl. When I specify the "width" or "height" attribute to the img, then the value is taken and divided by 2. WARNING: the value has to be an integer and a "px" (pixels) size.

We should find a way to reduce the size automatically.
