Subject [jira] Resolved: (PIVOT-393) Certain UI components do not properly respect system text anti-aliasing hints
Date Thu, 15 Apr 2010 16:04:49 GMT

     [ https://issues.apache.org/jira/browse/PIVOT-393?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Greg Brown resolved PIVOT-393.
------------------------------

      Assignee: Greg Brown  (was: Todd Volkert)
    Resolution: Fixed

I fixed the clipping issue. It was caused by an attempt to align the button part of the checkbox
and radio button to the renderer's baseline. The skins now simply vertically center the button
and renderer. We may revisit the baseline alignment in a future update, but this should be
OK for now.

> Some components render text using the drawString() method of Graphics2D and properly
set the text rendering hints using the getTextAntialiasingHint() method in the Platform class.
However, other components use a glyph vector that does not currently respect the text rendering
hints. These components should be updated to use a FontRenderContext containing the correct
text rendering hints:
> http://java.sun.com/javase/6/docs/api/java/awt/font/FontRenderContext.html#FontRenderContext(java.awt.geom.AffineTransform,%20java.lang.Object,%20java.lang.Object)
> Also, there is a minor issue with the use of getTextAntialiasingHint(): the AWT "awt.font.desktophints"
property may contain multiple hints (e.g. on my desktop it also defines KEY_TEXT_LCD_CONTRAST)
and Pivot is only looking at KEY_TEXT_ANTIALIASING. Additional methods should be added to
support the other values.
