[jira] [Updated] (FOP-2092) Fop invalid position combining mark for Thai text (CTL)
[ https://issues.apache.org/jira/browse/FOP-2092?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Glenn Adams updated FOP-2092: - Assignee: Glenn Adams (was: fop-dev) Fop invalid position combining mark for Thai text (CTL) --- Key: FOP-2092 URL: https://issues.apache.org/jira/browse/FOP-2092 Project: Fop Issue Type: Bug Components: fonts Affects Versions: all Environment: Operating System: All Platform: PC Reporter: Nattapong Sirilappanich Assignee: Glenn Adams Attachments: data.xslt, fop.log, fopThai5.pdf, test.fo.xml, test.pdf, thaidata.xml, thai.fo, Untitled.jpg 1. In order to make Thai glyph substitution work, the language tag must be dflt instead of th. This is because many popular Thai font use dflt. 2. Using dflt language, both GSUB and GPOS are used. The problem is after it used, all glyph are placed further to the right. Notes: 1. Many Thai combining glyph have negative alignment. I suspect this is involved in miss alignment calculation. 2. The ratio of displacement seem irrational. If it shifted to the left by the same ratio, it is still invalid. Question: Should dflt being load by default ?
