Bug with fonts containing spaces in family name

Post by mhilpert » Tue May 26, 2020 10:32 am

When a JFreeChart ist converted to SVG with JFreeSVG, the Font is not found when the resulting document is rendered. When using Batik to create the SVG file from the same JFreeChart object, the font is found. Reason: Batik encloses the font-family name in quotes and JFreeSVG does not. Font family names with spaces will result in font not found with JFreeSVG.

I was just trying this out, and I don't get any issue in Chrome, Safari or Firefox on a Mac. Which browser gives you the font not found error? Or is it some other SVG viewer?

It is generating a PDF with Apache FOP. We usually generate the SVgs (that are referenced in the XSLs) with Batik. Batik generates code like this:

Code: Select all

<g style="font-size:6px; fill:rgb(0,224,163); text-rendering:geometricPrecision; font-family:'78bcfc3c15c0b3bc - subset of LuminSans Std Reg'; stroke-linejoin:bevel; shape-rendering:crispEdges; stroke:rgb(0,224,163);">
and JFreeSVG generates:

Code: Select all

<g ><text x="134.04" y="173.46" style="fill: rgb(0,0,0); fill-opacity: 1.0; font-family: 78bcfc3c15c0b3bc - subset of LuminSans Std Reg; font-size: 6px;" clip-path="url(#_2993957146285518clip-0)">
The problem is the font name "78bcfc3c15c0b3bc - subset of LuminSans Std Reg" that contains spaces. This leads to "font not found error" when Apache FOP generates the final PDF from the XSl/XML/SVG As you can see: Batik (above) encloses the font name in quotes, JFreeSVG does not. The problem only occurs with fonts that have such names with spaces and special characters.
