Hello,
this is a duplicate request:
could you please review the following fix:
fix: http://cr.openjdk.java.net/~alitvinov/8023990/webrev.00
<http://cr.openjdk.java.net/%7Ealitvinov/8023990/webrev.00>
bug: https://bugs.openjdk.java.net/browse/JDK-8023990
When the FcFontConfiguration was added for using fontconfig on a
set of Linux platforms (as well as OpenSolaris) (the corresponding rfe
is here <https://bugs.openjdk.java.net/browse/JDK-8023990>), the
implementation of the method FcFontConfiguration.getFontDescriptors()
returned just an empty array. This functionality is actually not used by
anyone except of the PSPrinterJob which tries to find out whether the
string could be represented using PS embedded font. If this procedure
fails then the PSPrinterJob falls back to glyphs outline printing. As I
understand this normally happened for strings containing non-ASCII
characters. For ASCII strings PSPrinterJob usually selected the PS
embedded font. With the addition of FcFontConfiguration even ASCII
strings output starts to fall back to outlines.
The fix is some basic implementation of the getFontDescriptors()
functionality. The returned FontDecriptors don't contain missing glyph
information. Though it might be queried from the fontconfig library
(with some additional effort) this doesn't change the behavior of
PSPrinterJob, since all the fonts has the ISO 10646 encoding (UTF-8),
and the PSPrinterJob will still be falling back to outlines for any
non-ASCII strings.
Thanks!
Anton.
