Returns:

imageToBufferedImage

public static java.awt.image.BufferedImage imageToBufferedImage(java.awt.Image img)

Converts from Image to BufferedImage. To go the other direction, you can just cast BufferedImage as Image.

Parameters:

img - The Image to convert to BufferedImage

Returns:

A BufferedImage representation of the Image

rotateImage

public static java.awt.image.BufferedImage rotateImage(java.awt.image.BufferedImage img,
                                                       int degrees)

Rotates the given BufferedImage the specified number of degrees.

Parameters:

img - The BufferedImage to rotate

degrees - The number of degrees to rotate

Returns:

A rotated copy of the BufferedImage

getImageFromComponent

public static java.awt.image.BufferedImage getImageFromComponent(java.awt.Component c)

Get a BufferedImage representation of a component. This allows you to make 'screenshots' of components easily.

Parameters:

c - The component which you want an image of

Returns:

A BufferedImage of the given component
