Method Details

toBufferedImage

public static BufferedImage toBufferedImage(org.opencv.core.Mat matrix)

Converts/writes a Mat into a BufferedImage.

Parameters:

matrix - the mat

Returns:

BufferedImage

toBufferedImage

public static BufferedImage toBufferedImage(PlanarImage matrix)

releaseMat

public static void releaseMat(org.opencv.core.Mat mat)

releasePlanarImage

public static void releasePlanarImage(PlanarImage img)

convertToDataType

public static int convertToDataType(int cvType)

toMat

public static ImageCV toMat(RenderedImage img)

toMat

public static ImageCV toMat(RenderedImage img,
 Rectangle region)

toMat

public static ImageCV toMat(RenderedImage img,
 Rectangle region,
 boolean toBGR)

getBounds

public static Rectangle getBounds(PlanarImage img)

convertTo

public static BufferedImage convertTo(RenderedImage src,
 int imageType)

isBinary

public static boolean isBinary(SampleModel sm)

getPackedBinaryData

public static byte[] getPackedBinaryData(Raster raster,
 Rectangle rect)

For the case of binary data (isBinary() returns true), return the binary data as a packed byte array. The data will be packed as eight bits per byte with no bit offset, i.e., the first bit in each image line will be the left-most of the first byte of the line. The line stride in bytes will be (int)((getWidth()+7)/8). The length of the returned array will be the line stride multiplied by getHeight()

Parameters:

raster - the Raster

rect - the Rectangle

Returns:

the binary data as a packed array of bytes with zero offset of null if the data are not binary.

Throws:

IllegalArgumentException - if isBinary() returns false with the SampleModel of the supplied Raster as argument.

getUnpackedBinaryData

public static byte[] getUnpackedBinaryData(Raster raster,
 Rectangle rect)

Returns the binary data unpacked into an array of bytes. The line stride will be the width of the Raster.

Parameters:

raster - the Raster

rect - the Rectangle

Returns:

the binary data as a packed array of bytes with zero offset of null if the data are not binary.

Throws:

IllegalArgumentException - if isBinary() returns false with the SampleModel of the supplied Raster as argument.

setPackedBinaryData

public static void setPackedBinaryData(byte[] binaryDataArray,
 WritableRaster raster,
 Rectangle rect)

Sets the supplied Raster's data from an array of packed binary data of the form returned by getPackedBinaryData().

Parameters:

binaryDataArray - the byte

raster - the WritableRaster

rect - the Rectangle

Throws:

IllegalArgumentException - if isBinary() returns false with the SampleModel of the supplied Raster as argument.

setUnpackedBinaryData

public static void setUnpackedBinaryData(byte[] bdata,
 WritableRaster raster,
 Rectangle rect)

Copies data into the packed array of the Raster from an array of unpacked data of the form returned by getUnpackedBinaryData().

If the data are binary, then the target bit will be set if and only if the corresponding byte is non-zero.

Parameters:

bdata - the byte

raster - the WritableRaster

rect - the Rectangle

Throws:

IllegalArgumentException - if isBinary() returns false with the SampleModel of the supplied Raster as argument.

fixSignedShortDataBuffer

public static RenderedImage fixSignedShortDataBuffer(RenderedImage source)

Bug fix: CLibImageReader and J2KImageReaderCodecLib (imageio libs) do not handle negative values for short data. They convert signed short to unsigned short.

Parameters:

source - the RenderedImage

Returns:

the RenderedImage

convertRenderedImage

public static BufferedImage convertRenderedImage(RenderedImage img)
