Subject [jira] [Commented] (PDFBOX-4371) Improve ExtractText utility so that it can extract rotated text automatically
Date Thu, 29 Nov 2018 13:18:00 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-4371?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16703145#comment-16703145

Tim Allison commented on PDFBOX-4371:
-------------------------------------

Results on the new commoncrawl3 corpus:

http://162.242.228.174/reports/reports_pdfbox_2_0_13_commoncrawl3_angles.tgz

I still need to calculate time to process, and I'm aware that we had quite a few timeouts,
but I need to quantify those and figure out if those are my fault on the Tika side.

> In a first step, detect all rotations by analyzing the effective text rendering matrix.
In a second step, do a text extraction for each rotation by prepending an appropriate transform
to the page content stream (so that our text has angle == 0) and then filtering any rotated
text. Test file: the file from PDFBOX-4368.
