Constructor Detail

DirectDataBufferInt

public DirectDataBufferInt(int size)

Constructs an nio integer-based DataBuffer with a single bank and the specified size.

Parameters:

size - The size of the DataBuffer.

DirectDataBufferInt

public DirectDataBufferInt(int size,
                           int numBanks)

Constructs an nio integer-based DataBuffer with the specified number of banks, all of which are the specified size.

Parameters:

size - The size of the banks in the DataBuffer.

numBanks - The number of banks in the aDataBuffer.

DirectDataBufferInt

public DirectDataBufferInt(IntBuffer dataArray,
                           int size)

Constructs an nio integer-based DataBuffer with a single bank using the specified array.

Only the first size elements should be used by accessors of this DataBuffer. dataArray must be large enough to hold size elements.

Parameters:

dataArray - The integer array for the DataBuffer.

size - The size of the DataBuffer bank.

Method Detail

createBufferedImage

public static DirectDataBufferInt.BufferedImageInt createBufferedImage(int width,
                                                                       int height,
                                                                       int imageType,
                                                                       Point location,
                                                                       Hashtable<?,?> properties)

Creates a DirectDataBufferInt.BufferedImageInt using a direct color model in sRGB color space.
It uses a DirectDataBufferInt.DirectWritableRaster utilizing DirectDataBufferInt storage.

Note that due to using the custom storage type DirectDataBufferInt, the resulting BufferedImage's image-type is of TYPE_CUSTOM. We are not able to change this detail, since the AWT image implementation associates the image-type with a build-in storage-type. Use DirectDataBufferInt.BufferedImageInt.getCustomType() to retrieve the custom image-type, which will return the imageType value passed here.

Parameters:

width -

height -

imageType - one of TYPE_INT_ARGB, TYPE_INT_ARGB_PRE, TYPE_INT_RGB or TYPE_INT_BGR.

location - origin, if null 0/0 is assumed.

properties - Hashtable of String/Object pairs. Used for BufferedImage.getProperty(String) etc.
