B16ImageReader()	Constructor of the reader.

Method Summary

Modifier and Type	Method	Description
int	getHeight(int imageIndex)	Returns height.
IIOMetadata	getImageMetadata(int imageIndex)	Returns the metadata of the single image. imageIndex has to be 0.
Iterator<ImageTypeSpecifier>	getImageTypes(int imageIndex)	The only accepted image type is grayscale of the unsigned short values.
int	getNumImages(boolean allowSearch)	Returns always 1 - B16 can only encode a single image.
IIOMetadata	getStreamMetadata()	Returns null.
int	getWidth(int imageIndex)	Returns width.
static BildStruct	loadBildStruct(ImageInputStream stream)	Loads a Bild - structure of pco.sdk into java BildStruct class
BufferedImage	read(int imageIndex, ImageReadParam param)	Main method to read a BufferedImage from the input.
void	setInput(Object input, boolean seekForwardOnly, boolean ignoreMetadata)	Input is expected to be a standard ImageInputStream on the B16 file as generated by ImageIO.createImageInputStream(new File("image.b16"));

Constructor Details

B16ImageReader

public B16ImageReader()

Constructor of the reader.

Method Details

setInput

public void setInput(Object input,
boolean seekForwardOnly,
boolean ignoreMetadata)

Input is expected to be a standard ImageInputStream on the B16 file as generated by ImageIO.createImageInputStream(new File("image.b16"));

Overrides:

setInput in class ImageReader

getNumImages

public int getNumImages(boolean allowSearch)

Returns always 1 - B16 can only encode a single image.

Specified by:

getNumImages in class ImageReader

getWidth

public int getWidth(int imageIndex)
             throws IOException

Returns width.

Specified by:

getWidth in class ImageReader

Throws:

IOException

getHeight

public int getHeight(int imageIndex)
              throws IOException

Returns height.

Specified by:

getHeight in class ImageReader

Throws:

IOException

getImageTypes

public Iterator<ImageTypeSpecifier> getImageTypes(int imageIndex)
                                           throws IOException

The only accepted image type is grayscale of the unsigned short values.

Specified by:

getImageTypes in class ImageReader

Throws:

IOException

getStreamMetadata

public IIOMetadata getStreamMetadata()
                              throws IOException

Returns null. No metadata common for the whole stream since B16 allows only a single image - this metadata retrieved by getImageMetadata(int)

Specified by:

getStreamMetadata in class ImageReader

Throws:

IOException

getImageMetadata

public IIOMetadata getImageMetadata(int imageIndex)
                             throws IOException

Returns the metadata of the single image. imageIndex has to be 0.

Specified by:

getImageMetadata in class ImageReader

Throws:

IOException

read

public BufferedImage read(int imageIndex,
ImageReadParam param)
                   throws IOException

Main method to read a BufferedImage from the input. RawImageReader is used internally.

Specified by:

read in class ImageReader

Throws:

IOException

loadBildStruct

public static BildStruct loadBildStruct(ImageInputStream stream)
                                 throws IOException

Loads a Bild - structure of pco.sdk into java BildStruct class

Parameters:

stream -

Returns:

Throws:

IOException
