Constructor Detail

ImageProcessorReader

public ImageProcessorReader()

Constructs an ImageProcessorReader around a new image reader.

ImageProcessorReader

public ImageProcessorReader(IFormatReader r)

Constructs an ImageProcessorReader with the given reader.

Method Detail

makeImageProcessorReader

public static ImageProcessorReader makeImageProcessorReader(IFormatReader r)

Converts the given reader into a ImageProcessorReader, wrapping if needed.

openProcessors

public ij.process.ImageProcessor[] openProcessors(int no)
                                           throws FormatException,
                                                  java.io.IOException

Creates an ImageJ image processor object for the image plane at the given position.

Parameters:

no - Position of image plane.

Throws:

FormatException

java.io.IOException

openThumbProcessors

public ij.process.ImageProcessor[] openThumbProcessors(int no)
                                                throws FormatException,
                                                       java.io.IOException

Throws:

FormatException

java.io.IOException

openProcessors

public ij.process.ImageProcessor[] openProcessors(int no,
                                                  int x,
                                                  int y,
                                                  int w,
                                                  int h)
                                           throws FormatException,
                                                  java.io.IOException

Returns an array of ImageProcessors that represent the given slice. There is one ImageProcessor per RGB channel; i.e., length of returned array == getRGBChannelCount().

Parameters:

no - Position of image plane.

Throws:

FormatException

java.io.IOException

getNativeDataType

public java.lang.Class<?> getNativeDataType()

Description copied from interface: IFormatHandler

Returns the native data type of image planes for this reader, as returned by IFormatReader.openPlane(int, int, int, int, int) or IFormatWriter.savePlane(int, java.lang.Object). For most readers this type will be a byte array; however, some readers call external APIs that work with other types such as BufferedImage.

Specified by:

getNativeDataType in interface IFormatHandler

Overrides:

getNativeDataType in class ReaderWrapper

openPlane

public java.lang.Object openPlane(int no,
                                  int x,
                                  int y,
                                  int w,
                                  int h)
                           throws FormatException,
                                  java.io.IOException

Description copied from interface: IFormatReader

Obtains the specified image plane (or sub-image thereof) in the reader's native data structure. For most readers this is a byte array; however, some readers call external APIs that work with other types such as BufferedImage. The openPlane method exists to maintain generality and efficiency while avoiding pollution of the API with AWT-specific logic.

Specified by:

openPlane in interface IFormatReader

Overrides:

openPlane in class ReaderWrapper

Throws:

FormatException

java.io.IOException
