Low quality in extracted CMYK image
-----------------------------------
Key: PDFBOX-1220
URL: https://issues.apache.org/jira/browse/PDFBOX-1220
Project: PDFBox
Issue Type: Bug
Affects Versions: 1.6.0
Reporter: Daniel Bonniot de Ruisselet
Fix For: 1.7.0
Extracting the attached PDF with the following command:
java -jar app/target/pdfbox-app-1.7.0-SNAPSHOT.jar PDFToImage -imageType png
/tmp/WO2011140338-Page25.pdf
This generates image WO2011140338-Page251.png (attached).
This is a great improvement over pdfbox 1.6.0, which generates four copies of
the image (maybe because of the CMYK encoding?). Well done!
However the image is still of quite poor quality, apparently lower than the
actual image data in the PDF, when displayed with acrobat reader or evince
2.32.0 (screenshot attached too). It would be great if that could be fixed too.
