Method Detail

loadImage

public static final void loadImage(java.awt.Image image)
                            throws java.lang.InterruptedException

This method ensures that all pixels of the specified Image have been loaded and load them in other case

Parameters:

image - Image to load

Throws:

java.lang.InterruptedException - If there is an error while loading

scale

public static final java.awt.Image scale(java.awt.Image source,
                                         int newWidth,
                                         int newHeight,
                                         boolean keepRatio)

Convenient static method to resize down (minimize) instance of Image to the specified size. If source image size less then the specified then the method returns the source image without processing. If 'keepRatio' parameter is true then the specified image will resize proportionally and new size can be not exactly equal to the specified newWidth/newHeight.

Parameters:

source - image to resize down (minimize)

newWidth - width which source image should be minimized to (the result image can have less width if 'keepRatio' parameter set to true)

newHeight - height which source image should be minimized to (the result image can have less height if 'keepRatio' parameter set to true)

keepRatio - resize image proportionally

Returns:

new minimized instance of Image or source image if its' width and height less than the specified newWidth and newHeight

Throws:

java.lang.NullPointerException - If source image is null
