Map<String,Object> params)
Get an array of bytes describing the International Color Consortium (ICC)
specification for the color space of the image contained in the
input byteSource.
|

getMetadata(ByteSource byteSource,
Map<String,Object> params)
Get image metadata from the specified byte source.
|
String |
getName()
Get a descriptive name for the implementation of an ImageParser.

ImageParser
The params argument provides a mechanism for individual implementations to pass optional information into the parser. Not all formats will require this capability. Because the base class may call this method with a null params argument, implementations should always include logic for ignoring null input.
