    • getBufferedImage

      public BufferedImage getBufferedImage(ByteSource byteSource, RgbeImagingParameters 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<RgbeImagingParameters>
      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<RgbeImagingParameters>
      Returns:
      A valid string.

    • getDefaultParameters

      public RgbeImagingParameters getDefaultParameters()
      Description copied from class: AbstractImageParser
      Gets a default parameters instance for this parser.
      Specified by:
      getDefaultParameters in class AbstractImageParser<RgbeImagingParameters>
      Returns:
      default parameters instance

    • getIccProfileBytes

      public byte[] getIccProfileBytes(ByteSource byteSource, RgbeImagingParameters 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<RgbeImagingParameters>
      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, RgbeImagingParameters 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<RgbeImagingParameters>
      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, RgbeImagingParameters 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<RgbeImagingParameters>
      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, RgbeImagingParameters 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<RgbeImagingParameters>
      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<RgbeImagingParameters>
      Returns:
      a valid, subject-matter-specific string.
