DcxImageParser

public DcxImageParser()

Method Detail

getName

public java.lang.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 java.lang.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.

getMetadata

public ImageMetadata getMetadata(ByteSource byteSource,
                                 java.util.Map<java.lang.String,java.lang.Object> params)
                          throws ImageReadException,
                                 java.io.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 the ByteSource content does not conform to the format of the specific parser implementation.

java.io.IOException - In the event of unsuccessful data read operation.

getImageInfo

public ImageInfo getImageInfo(ByteSource byteSource,
                              java.util.Map<java.lang.String,java.lang.Object> params)
                       throws ImageReadException,
                              java.io.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:

writeImage

public void writeImage(java.awt.image.BufferedImage src,
                       java.io.OutputStream os,
                       java.util.Map<java.lang.String,java.lang.Object> params)

Description copied from class: ImageParser

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. So in cases where no optional specifications are supported, application code should pass in an empty instance of an implementation of the map interface (i.e. an empty HashMap).

Overrides:

writeImage in class ImageParser

Parameters:

src - An image giving the source content for output

os - A valid output stream for storing the formatted image

params - A non-null Map implementation supplying optional, format-specific instructions for output (such as selections for data compression, color models, etc.)

Throws:

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

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

                                  java.util.Map<java.lang.String,java.lang.Object> params)
                           throws ImageReadException,
                                  java.io.IOException

Extracts embedded XML metadata as XML string.

Specified by:

getXmpXml in class ImageParser

Parameters:

byteSource - File containing image data.

params - Map of optional parameters, defined in ImagingConstants.

Returns:

Xmp Xml as String, if present. Otherwise, returns null.
