- 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

  - 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 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.

    getImageInfo in class ImageParser
    
    Parameters:
    byteSource - A valid ByteSource object

    Throws:
    
    ImageReadException - In the event that the the specified content does not conform to the format of the specific parser implementation.
    
    IOException - In the event of unsuccessful data access operation.
