Method Detail

getRGBArray

public static int[] getRGBArray(int width,
                                int height)

Gets an array big enough to hold the pixels for an image of the given size. The array is not populated.

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.
