de.pco.imageio.RawImageReader

public class RawImageReader
extends ImageReader

Class for reading the BufferedImage from a RawImageInputStream built upon an ImageData. Will be used when needed to display the recorded images or the images that were loaded from a PCO-supported file by means of the wrapper functions of the C library (classes Recorder, Sdk).

Constructor Details

RawImageReader

public RawImageReader()

Standard constructor.

Method Details

setInput

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

RawImageInputStream expected as the input.

Overrides:

setInput in class ImageReader

getNumImages

public int getNumImages(boolean allowSearch)

Gets the number of images in the input.

Specified by:

getNumImages in class ImageReader

getWidth

public int getWidth(int imageIndex)
             throws IOException

Returns the width of the images in the input.

Specified by:

getWidth in class ImageReader

Throws:

IOException

getHeight

public int getHeight(int imageIndex)
              throws IOException

Returns the height of the images in the input.

Specified by:

getHeight in class ImageReader

Throws:

IOException

getImageTypes

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

Type grayscale unsigned short (when the input wraps ImageData) or unsigned byte (when the input wraps ImageDataCompressed).

Specified by:

getImageTypes in class ImageReader

Throws:

IOException

getStreamMetadata

public IIOMetadata getStreamMetadata()
                              throws IOException

Returns null. No metadata common for the whole stream except for height, width and isCompressed- all this contained in each metadata retrieved by getImageMetadata(int)

Specified by:

getStreamMetadata in class ImageReader

Throws:

IOException

getImageMetadata

public IIOMetadata getImageMetadata(int imageIndex)
                             throws IOException

Specified by:

getImageMetadata in class ImageReader

Throws:

IOException

read

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

Method for reading the particular image from the input RawImageInputStream into BufferedImage.

Specified by:

read in class ImageReader

Throws:

IOException
