Re: [jira] [Commented] (TIKA-3040) PDF inline OCR: Exception while processing certain image (others in same PDF work)

I've tried to explain it: https://cwiki.apache.org/confluence/display/TIKA/TikaOCR and better, here, with the 2 primary strategies: https://cwiki.apache.org/confluence/display/tika/PDFParser%20(Apache%20PDFBox) Then there's this on the horizon (??): https://issues.apache.org/jira/browse/TIKA-2749 On Wed, Feb 12, 2020 at 8:53 AM Eric Pugh wrote: > Is there a way that a mere mortal could understand to make that change? > Tika at times can be rather opaque in how the parameters all interact iwth > each other. > > > > On Feb 12, 2020, at 7:38 AM, Tim Allison (Jira) wrote: > > > > > >[ > https://issues.apache.org/jira/browse/TIKA-3040?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17035359#comment-17035359 > ] > > > > Tim Allison commented on TIKA-3040: > > --- > > > > Great!

Re: [jira] [Commented] (TIKA-3040) PDF inline OCR: Exception while processing certain image (others in same PDF work)
