Support units-per-em on SVG fonts #495

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
In the SVGTextNode code for handling SVG fonts, the positioning and scaling of 
glyph clones uses a 
hard coded value of 2048 for the size of the design grid for the font.

If the font does specify a value other than 2048, the resulting size and 
positioning of glyphs will be 
incorrect.  The default value for units-per-em is 1000.

An example file can be found at svggen/animate-elem-03-t.svg.  In this example 
units-per-em is 
missing and so a value of 1000 should be used.  Using 2048 results in the text 
being rendered 
approx half the size it should be.

Attached is a patch.
