Class ImageAccessor

java.lang.Object

imagingbook.lib.image.ImageAccessor

Direct Known Subclasses:

ImageAccessor.Rgb, ImageAccessor.Scalar

public abstract class ImageAccessor
extends Object

This class provides unified image access to all 4 types of images available in ImageJ. Byte, Short, Float: get/set values are passed as type float using getVal() and setVal(). Byte, Short, Float, Rgb: uses a float[] to pass in values using getPix() and setPix(). getVal() and getPix() interpolate for non-integer coordinates.

Method Detail

create

public static ImageAccessor create(ij.process.ImageProcessor ip)

Creates a new ImageAccessor instance for the given image, using the default out-of-bounds strategy and interpolation method.

Parameters:

ip - the source image

Returns:

a new ImageAccessor instance

create

public static ImageAccessor create(ij.process.ImageProcessor ip,
