Subject svn commit: r232952 - in /xmlgraphics/fop/trunk: src/java/org/apache/fop/image/ImageCache.java src/java/org/apache/fop/image/ImageFactory.java test/java/org/apache/fop/URIResolutionTestCase.java
Date Tue, 16 Aug 2005 07:35:50 GMT
Author: jeremias
Date: Tue Aug 16 00:35:42 2005
New Revision: 232952

URL: http://svn.apache.org/viewcvs?rev=232952&view=rev
Log:
Add a method to clear all image caches for testing purposes. It shouldn't be necessary anymore
to call such a method in a production environment or we have a problem with the image cache.
Testing SystemID resolution as well as StreamSource with an InputStream.
