Also OK to default to "fm_on", as long as we have some way to globally change to "fm_off" in client code. Also of note is that we have recently experienced the Mac OS ellipsis problem with Arabic characters at font size > 14, with both "fm_on" and "fm_off" scenarios. -- Piccolo2D Developers Group: http://groups.google.com/group/piccolo2d-dev?hl=en

Comment #5 on issue 191 by atdi...@gmail.com: Disabling FRACTIONAL_METRICS
on Windows yields incorrect bounds for text PSwing components
http://code.google.com/p/piccolo2d/issues/detail?id=191
Here's a summary of this issue to date:
While the default for all platforms seems to be FRACTIONAL_METRICS_ON
("fm_on"), Piccolo2D explicitly sets FRACTIONAL_METRICS_OFF ("fm_off") for
painting of PSwing nodes. As I understand it, this decision has been a part
of the PSwing class for a long while now and the primary motivation for
doing this is to avoid rendering of ellipses on Mac OS X platforms (by
using "fm_off", we prevent Mac OS from rendering ellipses for some text
renderings that, due to fractional metrics calculations can't fully render
within their bounds.)
After running several tests, however, it seems that painting w/ "fm_off"
causes more unpleasant behavior across systems than using the default
of "fm_on". On all systems, using "fm_off" causes noticeable jittering
while zooming. On Ubuntu/Java4, ellipses are actually rendered in this mode
and not in "fm_on". And on Windows 7, using Java4, ellipses are rendered
regardless of the setting.
I tested on a subset of {Win7, Snow Leopard, Ubuntu10} x {Java4, Java6} x
{FRACTIONAL_METRICS_ON, FRACTIONALMETRICS_OFF} and the outcome images will
come soon attached with tell-tale filenames:
| "fm_off"| "fm_on"
Windows7
Java4: jittering; ellipsed no
jitter; ellipsed
Java6:
jittering slight jittering
Ubuntu10
Java4: jittering; ellipsed
slight jittering
Java6 (openjdk): jittering; slight artifacts no jitter;
noticeable artifacts
Mac/Snow
Java6:
jittering slight jittering; ellipsed
It appears impossible to avoid ellipse-rendering using RenderingHints.
Also, using the default rendering hint "fm_on" yields much better behavior
(little or no jittering) otherwise.
It seems clients can avoid ellipses by explicitly setting preferred sizes
on their components, so there is a workaround.
With this data, I believe the *correct* route is to use the default "fm_on"
rendering hints (which is default on all systems I tested on), which also
resolves this issue.
I don't believe we can do this, however, in 1.3.* releases as clients may
already rely on this behavior. 1.3.* clients can workaround this issue by
overriding paint() behavior (not ideal, I know.)
Looking for P2D developers to comment. My vote is to move this ticket to
2.0 with the plan of removing our use "fm_off" in 2.0.

Comment #3 on issue 191 by heue...@gmail.com: Disabling FRACTIONAL_METRICS on Windows yields incorrect bounds for text PSwing components http://code.google.com/p/piccolo2d/issues/detail?id=191 Per http://developer.apple.com/library/mac/documentation/Java/Reference/Java_PropertiesRef/Articles/JavaSystemProperties.html There are some system properties on OSX that might affect how text is rendered and how this rendering hint is applied: apple.awt.graphics.EnableQ2DX Determines whether hardware acceleration is used to speed up rendering of simple primitives like images, lines, rects, and simple characters. In addition to using this flag, you need to enable Quartz 2D acceleration in the Quartz Debug application, included with the Xcode Developer Tools for Mac OS X. This is strictly a developer option. Java applications intended for use on Mac OS X should not rely on the presence of Quartz 2D acceleration. The default value is false. apple.awt.graphics.UseQuartz Determines whether Apple’s Quartz renderer is used instead of Sun’s 2D renderer. The default value is true for J2SE 5.0 and false for Java SE 6. Thus the OS check might not be sufficient. See also Issue 117 which documents my frustration with Piccolo2D text rendering in general. -- Piccolo2D Developers Group: http://groups.google.com/group/piccolo2d-dev?hl=en

Comment #1 on issue 191 by allain.lalonde: Disabling FRACTIONAL_METRICS on Windows yields incorrect bounds for text PSwing components http://code.google.com/p/piccolo2d/issues/detail?id=191 The solution you gave seems to be the way to go about it. Best case scenario is to have the fractional metrics enabled across the board and this gets us far closer to that. Even though it's obviously going against the very nature of cross platform Java code, working is working. Only gotcha there I think is that it would disable it for all mac platforms. Are we sure that there are no mac machines for which fractional metrics doesn't introduce an ellipsis? -- Piccolo2D Developers Group: http://groups.google.com/group/piccolo2d-dev?hl=en
