createCompatibleDestImage

public java.awt.image.BufferedImage createCompatibleDestImage(java.awt.image.BufferedImage src,
                                                              java.awt.image.ColorModel dstCM)

getRGB

public int[] getRGB(java.awt.image.BufferedImage image,
                    int x,
                    int y,
                    int width,
                    int height,
                    int[] pixels)

A convenience method for getting ARGB pixels from an image. This tries to avoid the performance penalty of BufferedImage.getRGB unmanaging the image.

Parameters:

image - a BufferedImage object

x - the left edge of the pixel block

y - the right edge of the pixel block

width - the width of the pixel arry

height - the height of the pixel arry

pixels - the array to hold the returned pixels. May be null.

Returns:

the pixels

setRGB

public void setRGB(java.awt.image.BufferedImage image,
                   int x,
                   int y,
                   int width,
                   int height,
                   int[] pixels)

A convenience method for setting ARGB pixels in an image. This tries to avoid the performance penalty of BufferedImage.setRGB unmanaging the image.

Parameters:

image - a BufferedImage object

x - the left edge of the pixel block

y - the right edge of the pixel block

width - the width of the pixel arry

height - the height of the pixel arry

pixels - the array of pixels to set

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

stringToColor

public static int stringToColor(java.lang.String colorSpec,
                                int defaultColor)

Convert the string color specification into an integer where bits 24-31 represent alpha, bits 16-23 represent red, bits 8-15 represent green, and bits 0-7 represent blue. The string specification can be of the form of a hexadecimal number, e.g. "0xff0000" for red, a standard color name, e.g. "red", or a CSS-style color specification, e.g. "#FF0000" for red. The color names supported are black, blue, cyan, darkGray, gray, green, lightGray, magenta, orange, pink, red, white, and yellow.

Parameters:

colorSpec - The string color specification.

defaultColor - The default color to return if the string is malformed.

Returns:

An integer color representation.
