public RgbeImageParser()

Method Detail

getName

public String getName()

Description copied from class: ImageParser

Get a descriptive name for the implementation of an ImageParser.

Specified by:

getName in class ImageParser

Returns:

a valid, subject-matter-specific string.

getDefaultExtension

public String getDefaultExtension()

Description copied from class: ImageParser

Get 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 ImageParser

Returns:

A valid string.

getAcceptedExtensions

protected String[] getAcceptedExtensions()

Description copied from class: ImageParser

Get an array of all accepted extensions

Specified by:

getAcceptedExtensions in class ImageParser

Returns:

A valid array of one or more elements.

getAcceptedTypes

protected ImageFormat[] getAcceptedTypes()

Description copied from class: ImageParser

Get an array of ImageFormat objects describing all accepted types

Specified by:

getAcceptedTypes in class ImageParser

Returns:

A valid array of one or more elements.

getMetadata

public ImageMetadata getMetadata(ByteSource byteSource,
                                 Map<String,Object> params)
                          throws ImageReadException,
                                 IOException

Description copied from class: ImageParser

Get 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 ImageParser

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:

ImageReadException - 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.

getImageInfo

public ImageInfo getImageInfo(ByteSource byteSource,
                              Map<String,Object> params)
                       throws ImageReadException,
                              IOException

Description copied from class: ImageParser

Get 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 ImageParser

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:

ImageReadException - 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.

getBufferedImage

public BufferedImage getBufferedImage(ByteSource byteSource,
                                      Map<String,Object> params)
                               throws ImageReadException,
                                      IOException

Description copied from class: ImageParser

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 ImageParser

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:

ImageReadException - 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.

getImageSize

public Dimension getImageSize(ByteSource byteSource,
                              Map<String,Object> params)
                       throws ImageReadException,
                              IOException

Description copied from class: ImageParser

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

Specified by:

getImageSize in class ImageParser

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:

ImageReadException - 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.

getICCProfileBytes

public byte[] getICCProfileBytes(ByteSource byteSource,
                                 Map<String,Object> params)
                          throws ImageReadException,
                                 IOException

Description copied from class: ImageParser

Get 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 ImageParser

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:

ImageReadException - 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.
