[JAVA2D] Font kerning/spacing issues ?
Hello all at Java2D, please take a look at this picture: www.classx.it/public/font2dtest.jpg the first LATIN text is rendered with Java2d (1.5, 1.6, winxp) the second is rendered with CorelDraw (but I get the same result with any other gfx program). You can notice an abnormal spacing between the A and the T glyphs in the java version. The CorelDraw version looks more correct, IMHO. I've tested many other fonts but I always got the same results. Where's the problem with java2d font rendering ?

Phil, you say thay the KERNING hint is not there by default because: 1) changes the overall text length I mean that you obviously can't expect text to be the same length with this option on, and so you need to make sure any code that is fussy about the length measures the font in the presence of the attribute. 2) requires extra processing steps at rendering time. Yes, I mean that text that is rendered with kerning will be much slower to render. This is unlikely to be an issue in practice unless you are doing massive and continual updates, but its a fact that if you ask for more work to be done, it takes longer. -phil. Do you mean that I may also encounter performance or compatibility issues ?

Re: [JAVA2D] Font kerning/spacing issues ?
Where's the problem with java2d font rendering ? Nothing's wrong. CorelDraw is a word-processor and is applying kerning. Not sure what you mean by any other gfx program. If you use windows notepad I see the same there in Font2DTest, which is what I would expect since windows GDI provides no way to request kerning. The way to get kerning in jdk6 is to say you want it by adding the appropriate attribute to the font : http://java.sun.com/javase/6/docs/api/java/awt/font/TextAttribute.html#KERNING Its not applied by default since it 1) changes the overall text length 2) requires extra processing steps at rendering time. -phil.
