Hi, I've just verified with Nutch trunk (upcoming 1.11): - Tika 1.10 is able to OCR embedded images if PDFParser.properties is modified accordingly in tika-app-1.10.jar - but parse-tika doesn't if same modifications are made in runtime/local/plugins/parse-tika/tika-parsers-1.10.jar
Needs some debugging to find out what is wrong. Please, feel free to file a bug report on https://issues.apache.org/jira/browse/NUTCH Thanks, Sebastian On 10/09/2015 06:21 PM, Sebastian Nagel wrote: > Hi, > > sorry, but I didn't try this by myself, just had > in mind that there has been a thread on the Tika > mailing list. > >> What is difference between ./plugins/parse-tika/parse-tika.jar and >> ./plugins/parse-tika/tika-parsers-1.8.jar ? > > parse-tika.jar contains the classes of Nutch's parse-tika plugin > which depends on the library tika-parsers-1.x.jar. > > Sebastian > > On 10/09/2015 02:54 PM, [email protected] wrote: >> Hello, >> >> I try do edit JAR file and edit >> 'org/apache/tika/parser/pdf/PDFParser.properties' : >> >> enableAutospace true >> extractAnnotationText true >> sortByPosition false >> suppressDuplicateOverlappingText false >> useNonSequentialParser false >> extractAcroFormContent true >> extractInlineImages true >> extractUniqueInlineImagesOnly false >> checkExtractAccessPermission false >> allowExtractionForAccessibility true >> >> but same result.
