Summary: Java does not display correctly some glyphs
Product: DejaVu
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Keywords: notourbug
Severity: normal
Priority: medium
Component: Sans
AssignedTo: dejavu-bugs at lists.freedesktop.org
ReportedBy: mathieu at thenesis.com
Hello,
I have written a program in Java to build font textures (for a video game).
Java, with J2SE 6, does not return correct informations about each glyph.
My program reported some glyphs as invalid (this means that glyph width, height
or advance are below zero or greater than the maximum specified in the font).
Some glyphs are not reported as invalid but are displayed at the wrong
position. I can send a PNG image of the generated texture if necessary.
DejaVu is the only font that does not work with my program. The bug comes
probably from the font manager in Java or it is just because Java does not
support OpenType. But it would be great if someone could fix this.
Here is the debug output for the font DejaVuSansLGC regular with size 20:
