Tilman Hausherr created PDFBOX-4655:
---------------------------------------
Summary: ImageIOUtil.WriteImage creates huge PNG images when used
with default quality on jdk11
Key: PDFBOX-4655
URL: https://issues.apache.org/jira/browse/PDFBOX-4655
Project: PDFBox
Issue Type: Bug
Components: Utilities
Affects Versions: 2.0.17
Reporter: Tilman Hausherr
Assignee: Tilman Hausherr
Fix For: 2.0.18, 3.0.0 PDFBox
[[email protected]] pointed us to a build failure in Tika on jdk11. The
cause may be different .PNG files - I noticed that PNG files saved with
ImageIOUtil.write() are huge when done with default quality, which is 1. In the
past that parameter had no effect for PNG files but apparently no more.
Todo:
- use flexible default value
- mention in Javadoc
- change command line tools (PDFToImage / ExtractImages)
- change one test
