public RawData2Image()

Method Detail

rawData2Image

public static BufferedImage rawData2Image(byte[][] data)

Parameters:

data - data to wrap

Returns:

result will be a BufferedImage with a GRAY colorspace and DataBuffer.TYPE_BYTE

rawData2Image

public static BufferedImage rawData2Image(short[][] data)

Parameters:

data - data to wrap

Returns:

result will be a BufferedImage with a GRAY colorspace and DataBuffer.TYPE_USHORT

rawData2Image

public static BufferedImage rawData2Image(int[][] data)

Parameters:

data - data to wrap

Returns:

result will be a BufferedImage with a GRAY colorspace and DataBuffer.TYPE_INT

rawData2Image

public static BufferedImage rawData2Image(float[][] data,
                                          boolean use32Bits)

Float data requires 4 Byte (32Bit) per data cell. It is common to reduce data depth by multiplying float values with 10 and map the rounded result to an unsigned short value (16Bit). This behavior can be controlled by the second parameter passed to this method. If set to true a image with 32Bit data depth and INT Databuffer will be created. Otherwise a 16Bit Image with an USHORT Databuffer will be created.
A default scale of 10 and no offset will be used

Parameters:

data - data to wrap

use32Bits -

Returns:

result will be a BufferedImage with a GRAY colorspace.

                                          float scale,
                                          float offset)

rawData2Image

public static BufferedImage rawData2Image(float[][] data,
                                          boolean use32Bits,
                                          ColorModel colorModel,
                                          SampleModel sampleModel)

Special version of the method which creates a new BufferedImage according to the models given.

Parameters:

data - data to wrap

use32Bits -

colorModel -

sampleModel -

Returns:

result will be a BufferedImage with the given color model
