de.pco.imageio.RawImageInputStream

All Implemented Interfaces:

Closeable, DataInput, AutoCloseable, ImageInputStream

public class RawImageInputStream
extends Object
implements ImageInputStream

Class for encapsulating the ImageData or a list of them (recorded from the camera or loaded from the file) for the input of RawImageReader. Opens a substream on a particular image by openSubstreamOnImage(int) and redirect all the methods of ImageInputStream to it.

Constructor Details

RawImageInputStream

public RawImageInputStream(List<? extends AbstractImageData> images)

Constructor from the list of the images.

Parameters:

images -

RawImageInputStream

public RawImageInputStream(AbstractImageData image)

Constructor from the single image

Parameters:

imageData -

Method Details

read

public int read()
         throws IOException

Reads from the stream;

Specified by:

read in interface ImageInputStream

Throws:

IOException

read

public int read(byte[] b,
int off,
int len)
         throws IOException

Reads from the stream into a byte array.

Specified by:

read in interface ImageInputStream

Throws:

IOException

isCompressed

public boolean isCompressed()

Returns whether the inputs are the compressed images (with the values of unsigned bytes).

Returns:

getWidth

public int getWidth()

Returns the width of the images in the stream.

Returns:

getHeight

public int getHeight()

Returns the height of the images in the stream.

Returns:

getNumImages

public int getNumImages()

Returns the number of images in the stream.

Returns:

getMetadata

public ImageMetadata getMetadata(int imageIndex)

Returns the metadata for particular image in the stream (a substream on this image does not have to be opened).

Parameters:

imageIndex -

Returns:

openSubstreamOnImage

public void openSubstreamOnImage(int index)
                          throws IOException

Since the RawImageInputStream can contain data of more images the substream on a particular image have to be opened by this method. All the standard ImageInputStream methods will then be redirected to this substream.

Parameters:

index -

Throws:

IOException

public void setByteOrder(ByteOrder byteOrder)

Byte order are set globally for the whole RawImageInputStream and then propagated to the particular substream.

Specified by:

setByteOrder in interface ImageInputStream
