public static void getRGB(BufferedImage image,
                          int[] pixels)

Gets the RGB pixels for the given image into the given array.

findImage

public static Point findImage(BufferedImage image,
                              BufferedImage findme,
                              double tolerance)

Finds one image within another.

Parameters:

tolerance - The portion of red, green, and blue differences allowed before ignoring a certain location. Zero implies an exact match.

Returns:

The top-left point where the top left of the image is found or null if not found within tolerance.

                              int imageWidth,
                              int imageHeight,
                              int[] findmePixels,
                              int findmeWidth,
                              int findmeHeight,
                              double tolerance)

Finds one image within another.

Parameters:

tolerance - The portion of red, green, and blue differences allowed before ignoring a certain location. Zero implies an exact match.

Returns:

The top-left point where the top left of the image is found or null if not found within tolerance.
