Method Detail

cloneImage

public static java.awt.image.BufferedImage cloneImage(java.awt.image.BufferedImage source,
                                                      int sourceType)

Clone an image.

Parameters:

source - original image to clone

sourceType - type of the source image (as defined in BufferedImage)

Returns:

a new image which is an exact copy of the source image

scaleImage

public static java.awt.image.BufferedImage scaleImage(java.awt.image.BufferedImage source,
                                                      int sourceType,
                                                      int newSize)

Scale an Image to a new size. The method keeps the aspect ratio of the original Image.

Parameters:

source - original image to scale down

sourceType - type of the source image (as defined in BufferedImage)

newSize - new size to which the image should be scaled

Returns:

a new image which is a scaled copy of the source image
