image-rotate

Rotates and translates a 2D ndarray.

Example

//Load input image
var baboon = require("luminance")(require("baboon-image"))
 
//Allocate storage for result
var result = require("zeros")([512, 512])
 
//Rotate the image
require("image-rotate")(result, baboon, Math.PI / 6.0)
 
//Save the result
require("save-pixels")(result, "png").pipe(process.stdout)

Output

Install

Install using npm:

npm install image-rotate

API

require("image-rotate")(output,input,theta[,iX,iY,oX,oY])

Rotates an image clockwise by theta radians about the point iX,iY in the source image and translated to the point oX,oY in the output image.

• output is an array that gets the output of rotating the image
• input is the image which is rotated
• theta is the amount to rotate by in radians
• iX,iY is the point to rotate about (default center of input)
• oX,oY is the image of the point to rotate about in output image (default center of output)

Returns output
