Engin Arici commented on BATIK-1027:
------------------------------------

I was able to solve the aliased text rendering issue with the following. @font-face might not be necessary.
<style type="text/css" >
	  <![CDATA[	  
		@font-face { font-family:'Oxygen-400'; src: url('fonts/Oxygen-Regular.ttf') format('truetype'); }
		@font-face { font-family:'Oxygen-300'; src: url('fonts/Oxygen-Light.ttf') format('truetype'); }
		@font-face { font-family:'Oxygen-700'; src: url('fonts/Oxygen-Bold.ttf') format('truetype'); }		
		svg {
			font-family: 'Oxygen-300';
			font-size: 12px;
		}
		
		svg text {
			text-rendering: geometricPrecision;
		}
]]>
	</style>

> Text that is rendered on top of a semi-transparent element will be rendered incorrectly if the JRE is Java 1.7. On Java 1.6 this issue doesn't occur.
> I have attached a very simple testcase that demonstrates this issue. On Java 1.6 the two "Hello World" texts are identical. On Java 1.7 the anti-aliasing for the upper text is broken.
> I was also able to reproduce the issue on batik-svn-12-10-01.
