Does not look like a FOP issue per se, but seems to point to either a bug or incomplete implementation in XGC's ImageLoaderRawPNG. 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!
