List of supportes output raster file formats

[[Quipsy] Markus Karg]

Dear Sirs,

thank you for bringing us Batik! 😊

I would kindly ask if you could post a complete list of contained output raster 
file formats. The transcoder’s website mentions JPG, PNG and TIFF, but I assume 
that more formats are bundled, like WebP for example?

A complete list would be very appreciated!

Thanks a lot!
