Creating a mapping from components

add - Adds a single pixel line - Adds a line of pixels zigzag - Adds a zigzag pattern rectangle of pixels fillEmpty - Adds a number of pixels without corresponding coordinate

Example:

// Create a 3x3 zigzag mapping
var mapping = new Pixelmapper()
.zigzag(0, 0, 3, 3, false);

Functions to do something with the created mapping

getPixel - Get the pixel at a coordinate getCoordinate - Get the coordinate of a pixel

Object functions

toJSON - Creates a JSON string that can be used to re-create the mapping using fromJSON fromJSON - Used to create a mapping from a JSON string created with toSJON Instead of using fromJSON you can also use the constructor:

Using the JSON conversion functions

The object can be converted and created to JSON: Example:

// Create a 3x3 zigzag mapping
var mapping = new Pixelmapper()
.zigzag(0, 0, 3, 3, false);

// Convert object to JSON string
var json = mapping.toJSON();

// Create new mapping object from JSON string
var mapping2 = new Pixelmapper(json);

// Or:
var mapping3 = new Pixelmapper().fromJSON(json);

For the exact arguments of the functions themselves take a look at the comments in pixelmapper.js.
