Constructor Detail

BufferedMirage

public BufferedMirage(BufferedImage image)

BufferedMirage

public BufferedMirage(BufferedImage image,
                      float percentageOfDataBuffer)

Parameters:

percentageOfDataBuffer - - the percentage of image's data buffer used by image for use in getEstimatedMemory. ie if this image is a subimage of another image, and they share a data buffer, this is the percentage of the size of this image compared to the source.
