Description copied from class: PNGChunk

Process a chunk. When this is called, the input stream needs to have read the type and length and be positioned at the start of the data. The default behavior is to eat the chunk. This should be the behavior only for UnknownChunk when we're done.

Overrides:

processChunk in class PNGChunk

Throws:

Exception
