Method Detail

isCompatibleURL

public boolean isCompatibleURL(ParsedURL purl)

Check if the Stream references an image that can be handled by this format handler. The input stream passed in should be assumed to support mark and reset. If this method throws a StreamCorruptedException then the InputStream will be closed and a new one opened (if possible). This method should only throw a StreamCorruptedException if it is unable to restore the state of the InputStream (i.e. mark/reset fails basically).

Specified by:

isCompatibleURL in interface URLRegistryEntry

Parameters:

url - The URL to inspect.

handleURL

public Filter handleURL(ParsedURL purl,
                        boolean needRawData)

Decode the URL into a RenderableImage

Specified by:
