getBufferedImage

public final BufferedImage getBufferedImage(ByteSource byteSource,
 WbmpImagingParameters params)
                                     throws ImagingException,
IOException

Description copied from class: AbstractImageParser

Gets a buffered image specified by the byte source (for sources that specify multiple images, choice of which image is returned is implementation dependent).

Specified by:

getBufferedImage in class AbstractImageParser<WbmpImagingParameters>

Parameters:

byteSource - A valid instance of ByteSource

params - Optional instructions for special-handling or interpretation of the input data (null objects are permitted and must be supported by implementations).

Returns:

A valid instance of BufferedImage.

Throws:

ImagingException - In the event that the specified content does not conform to the format of the specific parser implementation.

IOException - In the event of unsuccessful read or access operation.

getDefaultExtension

public String getDefaultExtension()

Description copied from class: AbstractImageParser

Gets the default extension for the format specified by an implementation of ImageParser. Some parsers can support more than one extension (i.e. .JPEG, .JPG; .TIF, .TIFF, etc.).

Specified by:

getDefaultExtension in class AbstractImageParser<WbmpImagingParameters>

Returns:

A valid string.

getDefaultParameters

public WbmpImagingParameters getDefaultParameters()

Description copied from class: AbstractImageParser

Gets a default parameters instance for this parser.

Specified by:

getDefaultParameters in class AbstractImageParser<WbmpImagingParameters>

Returns:

default parameters instance

getIccProfileBytes

public byte[] getIccProfileBytes(ByteSource byteSource,
 WbmpImagingParameters params)
                          throws ImagingException,
IOException

Description copied from class: AbstractImageParser

Gets an array of bytes describing the International Color Consortium (ICC) specification for the color space of the image contained in the input byteSource. Not all formats support ICC profiles.

Specified by:

getIccProfileBytes in class AbstractImageParser<WbmpImagingParameters>

Parameters:

byteSource - A valid ByteSource.

params - Optional instructions for special-handling or interpretation of the input data.

Returns:

If available, a valid array of bytes; otherwise, a null

Throws:

ImagingException - In the event that the specified content does not conform to the format of the specific parser implementation.

IOException - In the event of unsuccessful read or access operation.

getImageInfo

public ImageInfo getImageInfo(ByteSource byteSource,
 WbmpImagingParameters params)
                       throws ImagingException,
IOException

Description copied from class: AbstractImageParser

Gets image information from the specified ByteSource. Format-specific ImageParser implementations are expected to return a valid ImageInfo object or to throw an ImageReadException if unable to process the specified data.

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.

Specified by:

getImageInfo in class AbstractImageParser<WbmpImagingParameters>

Parameters:

byteSource - A valid ByteSource object

params - Optional instructions for special-handling or interpretation of the input data (null objects are permitted and must be supported by implementations).

Returns:

A valid image information object describing the content extracted from the specified data.

Throws:

ImagingException - In the event that the specified content does not conform to the format of the specific parser implementation.

IOException - In the event of unsuccessful data access operation.

getImageSize

public Dimension getImageSize(ByteSource byteSource,
 WbmpImagingParameters params)
                       throws ImagingException,
IOException

Description copied from class: AbstractImageParser

Gets the size of the image described by the specified ByteSource.

Specified by:

getImageSize in class AbstractImageParser<WbmpImagingParameters>

Parameters:

byteSource - A valid reference to a ByteSource.

params - Optional instructions for special-handling or interpretation of the input data.

Returns:

A valid instance of Dimension.

Throws:

ImagingException - In the event that the specified content does not conform to the format of the specific parser implementation.

IOException - In the event of unsuccessful read or access operation.

getMetadata

public ImageMetadata getMetadata(ByteSource byteSource,
 WbmpImagingParameters params)
                          throws ImagingException,
IOException

Description copied from class: AbstractImageParser

Gets image metadata from the specified byte source. Format-specific ImageParser implementations are expected to return a valid IImageMetadata object or to throw an ImageReadException if unable to process the specified byte source.

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.

Specified by:

getMetadata in class AbstractImageParser<WbmpImagingParameters>

Parameters:

byteSource - A valid byte source.

params - Optional instructions for special-handling or interpretation of the input data (null objects are permitted and must be supported by implementations).

Returns:

A valid, potentially subject-matter-specific implementation of the IImageMetadata interface describing the content extracted from the source content.

Throws:

ImagingException - In the event that the ByteSource content does not conform to the format of the specific parser implementation.

IOException - In the event of unsuccessful data read operation.

getName

public String getName()

Description copied from class: AbstractImageParser

Gets a descriptive name for the implementation of an ImageParser.

Specified by:

getName in class AbstractImageParser<WbmpImagingParameters>

Returns:

a valid, subject-matter-specific string.

writeImage

public void writeImage(BufferedImage src,
 OutputStream os,
 WbmpImagingParameters params)
                throws ImagingException,
IOException

Description copied from class: AbstractImageParser

Writes the content of a BufferedImage to the specified output stream.

The params argument provides a mechanism for individual implementations to pass optional information into the parser. Not all formats will support this capability. Currently, some of the parsers do not check for null arguments.

Overrides:

writeImage in class AbstractImageParser<WbmpImagingParameters>

Parameters:

src - An image giving the source content for output

os - A valid output stream for storing the formatted image

params - optional parameters, defining format-specific instructions for output (such as selections for data compression, color models, etc.)

Throws:

ImagingException - In the event that the output format cannot handle the input image or invalid params are specified.

IOException - In the event of an write error from the output stream.
