Method Detail

getDefaultParameters
public WbmpImagingParameters getDefaultParameters()
Description copied from class:ImageParser
Get a default parameters instance for this parser.- Specified by:
getDefaultParameters
in classImageParser<WbmpImagingParameters>
- Returns:
- default parameters instance
-
getName
public String getName()
Description copied from class:ImageParser
Get a descriptive name for the implementation of an ImageParser.- Specified by:
getName
in classImageParser<WbmpImagingParameters>
- 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 classImageParser<WbmpImagingParameters>
- Returns:
- A valid string.
-
getAcceptedExtensions
protected String[] getAcceptedExtensions()
Description copied from class:ImageParser
Get an array of all accepted extensions- Specified by:
getAcceptedExtensions
in classImageParser<WbmpImagingParameters>
- 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 classImageParser<WbmpImagingParameters>
- Returns:
- A valid array of one or more elements.
-
getMetadata
public ImageMetadata getMetadata(ByteSource byteSource, WbmpImagingParameters 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 classImageParser<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:
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, WbmpImagingParameters 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 classImageParser<WbmpImagingParameters>
- Parameters:
byteSource
- A valid ByteSource objectparams
- 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.
-
getImageSize
public Dimension getImageSize(ByteSource byteSource, WbmpImagingParameters params) throws ImageReadException, IOException
Description copied from class:ImageParser
Get the size of the image described by the specified ByteSource.- Specified by:

in classImageParser<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:
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, WbmpImagingParameters 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 classImageParser<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

- In the event of unsuccessful read or access operation.
-
dumpImageFile
public boolean dumpImageFile(PrintWriter pw, ByteSource byteSource) throws ImageReadException, IOException
Description copied from class:ImageParser
Write the ImageInfo and format-specific information for the image content of the specified byte source to a PrintWriter- Overrides:
dumpImageFile
in classImageParser<WbmpImagingParameters>
- Parameters:
pw
- print writer used for writing the ImageInfobyteSource
- A valid byte source.- Returns:
- A valid PrintWriter.
- Throws:
ImageReadException
- In the event that the specified content does not conform to the format of the specific parser implementation.IOException

-
getBufferedImage
public final BufferedImage getBufferedImage(ByteSource byteSource, WbmpImagingParameters 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 classImageParser<WbmpImagingParameters>

-
writeImage
public void writeImage(BufferedImage src, OutputStream os, WbmpImagingParameters params) throws ImageWriteException, IOException
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.
- Overrides:
writeImage
in classImageParser<WbmpImagingParameters>
- Parameters:
src
- An image giving the source content for outputos
- A valid output stream for storing the formatted imageparams
- optional parameters, defining 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.IOException
- In the event of an write error from the output stream.
