svn commit: r231223 -
/xmlgraphics/fop/trunk/src/java-1.4/org/apache/fop/image/ImageIOImage.java
Author: jeremias
Date: Wed Aug 10 05:56:30 2005
New Revision: 231223
URL: http://svn.apache.org/viewcvs?rev=231223&view=rev
Log:
AbstractFopImage subclass using ImageIO (JDK >= 1.4) to load images (works with GIF, too). Some of the code dealing with the BufferedImage could probably be extracted to a common subclass since it's mostly a copy from a different FopImage implementation.
Added:
xmlgraphics/fop/trunk/src/java-1.4/org/apache/fop/image/ImageIOImage.java (with props)
