[jira] [Comment Edited] (PDFBOX-3062) Text extraction and height
different in 2.0
[ https://issues.apache.org/jira/browse/PDFBOX-3062?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15034507#comment-15034507 ]

--------------------------------------------------------------
BBox + CapHeight isn't reliable either. Either we should be using a reliable metric, or using some logical metric, but combining two metrics doesn't make sense. The BBox is fine, it's just not what you want it to be, i.e. a meaningful proxy for a glyph's visual bounds.
