------------------------------------
Summary: BridgeException for SVGs with clip-path="url(...)" in JAR
files
Key: BATIK-1287
URL: https://issues.apache.org/jira/browse/BATIK-1287
Project: Batik
Issue Type: Bug
Components: SVG DOM
Affects Versions: 1.13
Reporter: Silviu Julean
BATIK-1127 was fixed (in FOP-2489) by modifying
{{ParsedURLDefaultProtocolHandler}}.
No fix was applied to {{ParsedURLJarProtocolHandler}}, therefore the issue
still reproduces with SVG files inside of JAR files.
*Steps to reproduce*
1. Embed a SVG file with an anchor clip path inside a JAR file.
2. Parse the document:
{noformat}
new
SAXSVGDocumentFactory(parser).createDocument("jar:file:/outerpath/app.jar!/innerpath/file.svg",
inputStream);{noformat}
3. Transcode it to PDF using FOP:
{noformat}
new PDFTranscoder().transcode(new TranscoderInput(document), ...);{noformat}
*Expected results*
The PDF file is generated as it would be if the document URL was a not a JAR
url.
*Actual results*
The anchor URL incorrectly resolves to:
{noformat}
jar:file:/outerpath/app.jar!/innerpath/#anchor-id{noformat}
Note the missing SVG file name.
{{batik-bridge}} then attempts to load an SVG document with this URL, resulting
in a {{TranscoderException}} caused by a "Premature end of file"
{{EOFException}}.
*Workaround*
1. Make a copy of {{ParsedURLJarProtocolHandler}}. The copy must still extend
{{ParsedURLDefaultProtocolHandler}}.
2. At the beginning of {{parseURL}}, return {{super.parseUrl(baseURL,
urlStr)}} if the {{urlStr}} starts with "#".
3. Create {{META-INF/services/org.apache.batik.util.ParsedURLProtocolHandler}}
containing the full class name of the patched class.
