| TextMatrixImageReader | | public class TextMatrixImageReader extends TextImageReader (Code) | | An image decoder for matrix of floating-point numbers. The default implementation creates
rasters of
DataBuffer.TYPE_FLOAT . An easy way to change this type is to overwrite
the
TextMatrixImageReader.getRawDataType method.

| Method Summary | |
| public void | close()
Closes the input stream and disposes the resources that was specific to that stream. | | public int | getHeight(int imageIndex)
Returns the height in pixels of the given image within the input source.
Calling this method may force loading of full image.
Parameters:
imageIndex - the index of the image to be queried. | | public IIOMetadata | getImageMetadata(int imageIndex)
Returns metadata associated with the given image.
Calling this method may force loading of full image.
Parameters:
imageIndex - The image index. | | public int | getWidth(int imageIndex)
Returns the width in pixels of the given image within the input source.
Parameters:
imageIndex - the index of the image to be queried. | | public BufferedImage | read(int imageIndex, ImageReadParam param)
Reads the image indexed by
imageIndex .
Parameters:
imageIndex - The index of the image to be retrieved.
Parameters:
param - Parameters used to control the reading process, or null. |
| TextMatrixImageReader | | protected TextMatrixImageReader(ImageReaderSpi provider)(Code) | | Constructs a new image reader.
Parameters:
provider - the provider that is invoking this constructor, or null if none. |
| close | | public void close() throws IOException(Code) | | Closes the input stream and disposes the resources that was specific to that stream.
|
| getHeight | | public int getHeight(int imageIndex) throws IOException(Code) | | Returns the height in pixels of the given image within the input source.
Calling this method may force loading of full image.
Parameters:
imageIndex - the index of the image to be queried. Image height.
throws:
IOException - If an error occurs reading the height informationfrom the input source. |
| getImageMetadata | | public IIOMetadata getImageMetadata(int imageIndex) throws IOException(Code) | | Returns metadata associated with the given image.
Calling this method may force loading of full image.
Parameters:
imageIndex - The image index. The metadata, or null if none.
throws:
IOException - If an error occurs reading the data information from the input source. |
| getWidth | | public int getWidth(int imageIndex) throws IOException(Code) | | Returns the width in pixels of the given image within the input source.
Parameters:
imageIndex - the index of the image to be queried. Image width.
throws:
IOException - If an error occurs reading the width informationfrom the input source. |
| read | | public BufferedImage read(int imageIndex, ImageReadParam param) throws IOException(Code) | | Reads the image indexed by
