Constructor Detail

ThumbsDBImageReader

public ThumbsDBImageReader()

ThumbsDBImageReader

protected ThumbsDBImageReader(ThumbsDBImageReaderSpi pProvider)

Method Detail

resetMembers

protected void resetMembers()

Specified by:

resetMembers in class ImageReaderBase

dispose

public void dispose()

Overrides:

dispose in class ImageReaderBase

isLoadEagerly

public boolean isLoadEagerly()

setLoadEagerly

public void setLoadEagerly(boolean pLoadEagerly)

Instructs the reader wether it should read and cache alle thumbnails in sequence, during the first read operation.

This is useful mainly if you need to read all the thumbnails, and you need them in random order, as it requires less repositioning in the underlying stream.

Parameters:

pLoadEagerly - true if the reader should read all thumbs on first read

read

public BufferedImage read(int pIndex,
                          ImageReadParam pParam)
                   throws IOException

Reads the image data from the given input stream, and returns it as a BufferedImage.

Specified by:

read in class ImageReader

Parameters:

pIndex - the index of the image to read

pParam - additional parameters used while decoding, may be null, in which case defaults will be used

Returns:

a BufferedImage

Throws:

IndexOutOfBoundsException - if pIndex is out of bounds

IllegalStateException - if the input source has not been set

IOException - if an error occurs during reading

read

public BufferedImage read(String pName,
                          ImageReadParam pParam)
                   throws IOException

Reads the image data from the given input stream, and returns it as a BufferedImage.

Parameters:

pName - the name of the image to read

pParam - additional parameters used while decoding, may be null, in which case defaults will be used

Returns:

a BufferedImage

Throws:

FileNotFoundException - if the given file name is not found in the "Catalog" entry of the CompoundDocument

IllegalStateException - if the input source has not been set

IOException - if an error occurs during reading

abort

public void abort()

Overrides:

abort in class ImageReader

setInput

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

Overrides:

setInput in class ImageReaderBase

getNumImages

public int getNumImages(boolean allowSearch)
                 throws IOException

Overrides:

getNumImages in class ImageReaderBase

Throws:

IOException

             throws IOException

Specified by:

getWidth in class ImageReader

Throws:

IOException

getHeight

public int getHeight(int pIndex)
              throws IOException

Specified by:

getHeight in class ImageReader

Throws:

IOException

getImageTypes

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

Specified by:

getImageTypes in class ImageReader

Throws:

IOException
