Subject [jira] Commented: (PIVOT-393) Certain UI components do not properly respect system text anti-aliasing hints

Sandro Martini commented on PIVOT-393:
--------------------------------------

Hi to all,

> I don't have any plans to take the before/after demos down.
very good :-) , so i can make other tests

> @Sandro: in your screenshots it seems that "before" you had no AA at all, and "after"
you have soft-AA without subpixel rendering. Do you have an LCD?
Yes, I have an LCD , with default settings (both on Win XP and in Windows 7 and here I'll
make some screenshots as soon as possible)

> 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.
