public class ImageIO
extends java.lang.Object

This is a class providing methods to convert image data stored in a DicomImage to an ImageProducer and back.
Supported DICOM Images:

Photometric Interpretation	Pixel Depth	ColorModel used
MONOCHROME?	8	IndexColorModel
MONOCHROME?	>8	GrayColorModel
PALETTE COLOR	8	IndexColorModel
RGB	8	DirectColorModel

Constructor Summary

ImageIO(DicomImage d)
Constructs a new ImageIO object for in- / output of ImageProducers.

Method Summary

java.awt.image.ImageProducer	getImageProducer() Constructs an ImageProducer based on the pixels of the first (or only) frame.
java.awt.image.ImageProducer	getImageProducer(int i) This method constructs an ImageProducer based on the pixels of frame with index i.
java.util.Vector	getImageProducers() Builds an ImageProducer for all the frames in the image and returns them in a Vector.
DicomImage	getSource() returns the specified DICOMObject.
void	setImageProducer(java.awt.image.ImageProducer ip) Reads an ImageProducer and converts the image data into the single-frame DicomImage.
int	size() returns the number of frames in the specified DICOMObject.

Constructor Detail

ImageIO

public ImageIO(DicomImage d)
        throws DicomException

Constructs a new ImageIO object for in- / output of ImageProducers.
Note: the DicomImage is stored referentially, not copied. Any changes are made directly to the DicomImage.

Parameters:

d - - the source/target for Image IO

Throws:

DicomException

Method Detail

getImageProducer

public java.awt.image.ImageProducer getImageProducer()
                                              throws DicomException

Constructs an ImageProducer based on the pixels of the first (or only) frame.

Throws:

DicomException

getImageProducer

public java.awt.image.ImageProducer getImageProducer(int i)
                                              throws DicomException

This method constructs an ImageProducer based on the pixels of frame with index i. The index of the frames starts with 0. Construction of an ImageProducer out of a RGB image or a MONOCHROME image with depth > 8 bits can be rather slow because it requires a reorganisation of the pixel data. If the image data is compressed, it is decoded using the com.archimed.dicom.codec package.

Returns:

an ImageProducer that essentialy is an MemoryImageSource with a different ColorModel depending on the image type (specified above).

Throws:

DicomException - is thrown when something is wrong with the image data, when the index is out of bounds or when the image type is not supported.

getImageProducers

public java.util.Vector getImageProducers()
                                   throws DicomException

Builds an ImageProducer for all the frames in the image and returns them in a Vector.

Returns:

all the available ImageProducers stored in a Vector

Throws:

DicomException

getImageProducer

setImageProducer

public void setImageProducer(java.awt.image.ImageProducer ip)

Reads an ImageProducer and converts the image data into the single-frame DicomImage. The method is synchronized because it has to wait for all of the imagedata to be delivered by the ImageProducer.

Parameters:

ip - the ImageProducer containing the imagedata to be stored

size

public int size()

returns the number of frames in the specified DICOMObject.

getSource

public DicomImage getSource()

returns the specified DICOMObject.
