++ The ImageLoaderPNG and ImageLoaderRawPNG have a hard-coded penalty of 1000 and as such the + ImageLoaderImageIO image loader will be selected by default when loading PNGs unless + the latter is disabled by awarding a INFINITE penalty to it, or one of the former two is + promoted by awarding a strong negative penalty (say, -10000) to it. +
+- PNG images are supported through an Image I/O codec. Transparency is supported but - not guaranteed to work with every output format. + FOP native support of PNG only includes the variants with 8 bits per channel and without + interlacing. Native support requires using the ImageLoaderRawPNG image loader. + Support through a Image I/O codec can use either the internal XGC PNG codec or the JRE PNG + codec. The associated image loaders are, respectively, ImageLoaderPNG and ImageLoaderImageIO. + Transparency is supported but not guaranteed to work with every output format.
