Opens an image. All common image formats and Bio-Formats are supported. Grayscale images will be read-in as 8-bit. Color images will prompt the user for channel operation to decide how to convert the color image to 8-bit grayscale. Variables in the operation can be “Auto”, “auto”, “r, R, red, or Red”, “g, G, green, or Green”, “b, B, blue, or Blue”, and “a, A, alpha, or Alpha”. “Auto” eliminates the hue and saturation information while retaining the luminance.
