Tilman Hausherr updated PDFBOX-4655:
------------------------------------
Description:
[[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 on jdk12 / 13,
which is 1. In the past (jdk8 and before) 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
