run
public static ImagePlus run(ImagePlus img1, ImagePlus img2, java.lang.String operation)
Performs arithmetic options on two images and returns the result, where 'operation' ("add","subtract", "multiply","divide", "and", "or", "xor", "min", "max", "average", "difference" or "copy") specifies the operation. If 'operation' does not contain 'create' or '32-bit', the result is also saved in 'imp1" and null is returned if "imp1" is displayed. The 'operation' argument can include up to three modifiers: "create" (e.g., "add create") causes the result to be returned as a new image, "32-bit" causes the result to be returned as 32-bit floating-point image and "stack" causes the entire stack to be processed. As an example,imp3 = ImageCalculator.run(imp1, imp2, "divide create 32-bit");
divides 'imp1' by 'imp2' and returns the result as a new 32-bit image.
