Description

Overview

There seems to be an issue/bug in xmlgraphics-commons which throws an error whenever an interlaced image is encountered. The error is the following:

Caused by: java.lang.RuntimeException: Unsupported PNG interlace method: 1

Steps to reproduce

1. Have the following installed:
   1. FOP 2.9
   2. Batik 1.17 (which uses/depends on xmlgraphics-commons 2.9)
2. Try to process <fo:external-graphic src="file:\\\D:\interlaced_image.png"/> (the image has been attached to the issue)

Expected behavior

A correct PDF is generated

Actual behavior

The above error message is generated

Additional notes

FOP 2.9 with Batik 1.16 works (probably because it uses/depends on xmlgraphics-commons 2.7), but Batik 1.16 is vulnerable.
