Method Detail

register

public static void register(String classname,
                            int priority)

Register a new BitmapEncoder implementation.

Parameters:

classname - fully qualified classname of the BitmapEncoder implementation

priority - lets you define a priority for an encoder. If you want to give an encoder a high priority, assign a value of 100 or higher.

supports

public static boolean supports(BitmapEncoder encoder,
                               String mime)

Indicates whether a specific BitmapEncoder implementation supports a particular MIME type.

Parameters:

encoder - BitmapEncoder to inspect

mime - MIME type to check

Returns:

true if the MIME type is supported

supports

public static boolean supports(String mime)

Indicates whether a particular MIME type is supported by one of the registered BitmapEncoder implementations.

Parameters:

mime - MIME type to check

Returns:

true if the MIME type is supported

getInstance

public static BitmapEncoder getInstance(String mime)

Returns a BitmapEncoder instance for a particular MIME type.

Parameters:

mime - desired MIME type

Returns:

a BitmapEncoder instance (throws an UnsupportedOperationException if no suitable BitmapEncoder is available)

getSupportedMIMETypes

public static Set getSupportedMIMETypes()

Returns a Set of Strings with all the supported MIME types from all registered BitmapEncoders.

Returns:

a Set of Strings (MIME types)
