I've been working on printing in my app and I have encountered a few
problems. First I'm finding an extreme slowness when printing (via
Print dialog -> Preview button) any space, tab or U+2588 (FULL BLOCK)
characters in the AppleSymbols font. Every page that contains these
glyphs prints slowly. In my tests on each full page of styled text
(plus some small graphics) there are an average of 20 occurrences of
these glyphs. If I change the font to Arial or the characters to Xs,
for instance, printing is 10 x as fast (but, of course, it doesn't
look right).
I'm calling ATSUDrawText and using the CGContextRef returned by
PMSessionGetGraphicsContext(... kPMGraphicsContextCoreGraphics ...).
However, I don't think that this is a problem with my code FLW.
(Famous Last Words)
When using Arial instead Shark shows about 18-30% in the same code,
but it's too short a time to grab a good sample (< 1 sec).
FYI I'm running OSX 10.4.2 on a 2x2.5GHz G5 and targeting the 10.3.9
SDK.
So, Is there any way I can make this print faster? (Or should I just
shoot another bug report at the Radar black hole?)
Any help or insights anyone can offer me (relating to this problem)
will be greatly appreciated.
More problems latter,
