Summary: [UPDATED] Improve text rendering in swf8, add api for text rendering
hints
New Features: new api on LzText to control swf8 rendering parameters
Bugs Fixed:
Technical Reviewer: max
QA Reviewer: (pending)
Doc Reviewer: (pending)
Documentation:
Added four new virtual attributes to LzText, each of which control an aspect
of advanced text rendering in swf8: sharpness, thickness, antiAliasType,
and gridFit. These attributes only have an effect in swf8; in other runtimes,
they will quietly be no-ops. We provide set/get for each of these new virtual
attributes, and give them good initial and default values.
Note that the default values are set such that <text>boring</text> will
use normal rendering, because advanced rendering causes a performance hit. To
get the advanced rendering, just set antiAliasType="advanced" on the text
object.
Added capability "advancedfonts" for these text rendering attributes; made it
true for swf, false for dhtml.
Release Notes:
To get advanced rendering in swf8, just set antiAliasType="advanced" on a text
object.
Details:
Tests:
http://localhost:8080/legals/test/lztest/lztest-textstyle.lzx?lzr=swf8&debug=true
sussurate should look good but blurry. mimsy borogroves should look not great.
"i should look bad" and "pixel gridfit" should have weird color bands around
the text
If you visit that url in Flash Player 7, all the text should look the same, and
a
bit crunchy.
"ant doc" still works
http://localhost:8080/legals/test/text/renderingcomparison.lzx?lzr=swf8
should look really cool, with each of the text objects in the top three
rows looking slightly different.
