[jira] [Commented] (PDFBOX-3101) Chinese character displayed with bad quality

    [ https://issues.apache.org/jira/browse/PDFBOX-3101?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15002317#comment-15002317 ] 

Tilman Hausherr commented on PDFBOX-3101:
-----------------------------------------

The patch label is there but there is no patch.

The quality gets better with better resolution. Most are good with 300, although one (that has very fine horizontal lines, that is a known problem) is only good with 600dpi.
