Hi John, > 1. Sub-pixel positioning ( https://javafx-jira.kenai.com/browse/RT-14187 )
Yes, if all goes well RT-14187 will get fixed for FX8. Notes: -On Mac we already have sub-pixel positioned glyphs. -LCD text we also have sub-pixel positioned glyphs. -The main one that I feel we are missing is grayscale text for Windows. -It is very unlikely we will have time to do anything for Linux this time around. 2. Kerning ( https://javafx-jira.kenai.com/browse/RT-7472 ) Not target for 8. 3. Is it just my imagination. Webview node and text node both use the very same drawing code in Prism. I would not expect to see any difference... I hope this helps, Felipe On Aug 27, 2013, at 3:42 AM, John C.
