get-pixels

Given a URL/path, grab all the pixels in an image and return the result as an ndarray. Works both in browserify and in node.js.

Note On the node side, currently only supports PNG and PPM. Patches welcome!!!

Example

var getPixels = require("get-pixels")

getPixels("lena.png", function(err, pixels) {
  if(err) {
    console.log("Bad image path")
    return
  }
  console.log("got pixels", pixels.shape)
})

Install

npm install get-pixels

require("get-pixels")(url, cb(err, pixels))

Reads all the pixels from url into an ndarray.

  • url is the path to the file
  • cb(err, pixels) is a callback which gets triggered once the image is loaded.

Returns An ndarray of pixels in raster order having shape equal to [rows, columns, channels].
