Smaller text lost with strokeSVGText=false
Summary: Smaller text lost with strokeSVGText=false
Product: Fop
Version: 0.15
Platform: Other
OS/Version: Other
Status: NEW
Severity: Normal
Priority: Other
Component: pdf renderer
AssignedTo: fop-dev@xml.apache.org
ReportedBy: spam_from_apache_bugzilla@chezphil.org
The example below contains SVG text inside an FO document. There are two
SVG diagrams which are almost identical - their contents should be shown
identically. The only difference is that in the second case all the dimensions
have been reduced by a factor of ten, which is balanced by an increase by the
same factor in an enclosing scale transform.
With strokeSVGText=true (the default) it works fine.
With strokeSVGText=false, the first version is shown correctly. In the second
version, only the second two text items are shown. It seems that text items
with a font-size of less than 1 are not plotted. That's a font-size of less
than 1 actually specified on the svg:text element, not after scaling has
been taken into account.
I have reported another issue where something similar happens to stroke-width
(bug 4766) - is this related?
This is with FOP 0.20.2-RC.
I would be very grateful for any feedback since without a fix I will have to
engineer a very messy workaround...
Here is the example:
