Changes to the Code Base

• Image Loading: Support for passing in SAXSource instance. Committed by JM. Thanks to Adam Strzelecki. See Issue 44466.
• The package org.apache.xmlgraphics.image.loader was added. It contains a general image loading framework for various image formats (bitmap & vector). Committed by JM.
• XMP: Added support for structured properties. Committed by JM.
• PostScript: Added classes for "BoundingBox" DSC comments. Committed by JM.
• Added support for classpath resources (find files in JAR files in the classpath using their MIME type) Committed by JM. Thanks to Max Berger. See Issue 42980.
• Application of the patch in Bugzilla 43069: New Macro safe-set-page-device which guards against the possibility of invalid/unsupported postscript key/values being issued to the implementing postscript page device Committed by CB. Thanks to Adrian Cumiskey. See Issue 43069.
• Bugfix for ISO 8601 date formatting with negative time zones in the XMP package. Committed by JM.
• Bugfix for XMP serialization: arrays with only one entry were serialized as simple property which could lead to information loss for merge operations. Committed by JM.
• PostScript: Fixed %%EOF checking for nested documents. Committed by JM.
• PostScript: Improved robustness of DSC parsing (multi-line comments with no value on the first line don't cause crashes anymore, fallback for unparsable DSC comments). Committed by JM.
• Fixed a possible NPE in the TIFF codec (in the TIFFImage constructor). Committed by JM. Thanks to Sergey Orlov. See Issue 43120.
• Support for Java 1.3 has been dropped. Java 1.4 or later is required now. Committed by JM.
