[jira] [Commented] (PIVOT-697) Font looks different when text is
selected across multiple lines in TextArea
[ https://issues.apache.org/jira/browse/PIVOT-697?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13009978#comment-13009978 ]
Taro App commented on PIVOT-697:
--------------------------------
As I understand, Java default anti-aliasing logic is platform dependent (Windows/Linux, CRT/LCD.) Windows default anti-aliasing logic is also font size dependent (small fonts are not anti-aliased.) But I think text should be anti-aliased in the same way on the same PC, the same font size and the same settings. I see there are several places in the Pivot code where RenderingHints.VALUE_ANTIALIAS_ON or RenderingHints.VALUE_ANTIALIAS_OFF are set. I wonder if those values are incorrectly set, or incorrectly not-set when rendering TextArea.

> 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.
