Thanks Andreas for your inputs.. Initially with FOP 1.0, I tried ImageLoaderPNG. However, the resolution of the image gets impacted. So I shifted to ImageLoaderRawPNG which rendered it properly. Attaching the files. 1) graph.png - The original PNG image 2) FOP-PNGImageLoader-differences.docx - The rendered images with ImageLoaderPNG and ImageLoaderRawPNG
So this was working fine with FOP 1.0 However, FOP 2.0 is not able to render the image and throws following exception.. If someone can help me confirm that this is a bug with XGC, then should I post it on a different mailing list?

Difficult to say without the exact PNG that is used, but the class in XGC does contain a comment indicating that '...this image loader does not handle all kinds of PNG images...', so perhaps this is a known deficiency. Have you tried giving the plain ImageLoaderPNG a higher precedence (= lower penalty value)? If you are allowed to upload the PNG in question to Apache JIRA, do feel free to log an issue against XML Graphics Commons and attach it there, so the issue can be investigated. HTH!
