[jira] [Commented] (PDFBOX-5049) PlainText.Paragraph.getLines
extremely slow on long lines
[ https://issues.apache.org/jira/browse/PDFBOX-5049?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17277779#comment-17277779 ]
Jairo Figueroa Jiménez commented on PDFBOX-5049:
------------------------------------------------
Has no sense make one loop what running 99760 bytes again to again. The solution is store the code following and order of unicode in ArrayList. After is running loop with list code and recover to with getCodeToWidthMap()... It would be something like this:
