Subject [jira] Commented: (PIVOT-141) Use hardware-accelerated Transparencies features when available
Date Fri, 05 Jun 2009 14:48:07 GMT

    [ https://issues.apache.org/jira/browse/PIVOT-141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12716627#action_12716627

Greg Brown commented on PIVOT-141:

Note that, if display backgroundColor style is null, DisplayHost may need to clear the backbuffer
before painting into it so we don't get artifacts.

> Detect if hardware-accelerated Transparencies features are available (depending on the
Java platform and version, starting from Java 6 Update 10) and use them, or if not available
do nothing.
> Note that this needs some additional parameters in the wtk files ... 
> Some hints:

> Ah, an interesting thing to note it that in Java 7 this will be put in a standard package
(and maybe will remain also in the current package).
