• Dropped support for Java 6 - Supported versions are now Java 7 to 17.

機能

• Added PDFImage.setStrictDPI() to mimic the image DPI extraction rules from HTML5.

不具合の修正

• The "Resource Merge" step which can be used to potentially reduce the size of files assembled from multiple smaller documents was sometimes writing out fonts with a ToUnicode that was incomplete, or failing to identify duplicate glyphs because the originals came from fonts with a different "longloc" flag. Both have now been fixed.
• Some very specific workflows could lead to a synchronization lock when...
