Taro App commented on PIVOT-697:
--------------------------------
Here's some more info:
On my Windows XP note PC,
((java.util.Map)Toolkit.getDefaultToolkit().getDesktopProperty("awt.font.desktophints")).get(RenderingHints.KEY_TEXT_ANTIALIASING)
returns "LCD HRGB antialiasing text mode" so anti-alias method used should be
LCD_HRGB.
(This is how Pivot determines anti-alias method in
org.apache.pivot.wtk.Platform.)
Compare these two very closely:
- Test1.SingleLineSelectEnglish.png
-> both selected and non-selected texts are anti-aliased with LCD_HRGB method.
- Test2.MultipleLineSelectEnglish.png
-> non-selected text is rendered with LCD_HRGB method, but selected text is
rendered with some other anti-alias method. (maybe LCD_VRGB?)
Windows anti-alias is something close to LCD_HRGB. Pivot anti-alias is LCD_HRGB
except for multiple-line-selected text.
Who's changing anti-alias method? Java? Can Pivot do something to workaround
this?
I'll run some more tests.

> Font looks different when text is selected across multiple lines in TextArea.
> When the selection is within a single line, font looks the same.
> For English text, this font change is subtle and can be ignored.
> For Japanese text, this font change is obvious and looks weird.
> I'm not sure if this is platform dependent or font dependent.
> May have something to do with how Java2D renders fonts.
> I will attach screen shots and test codes.
