Reads the pixels of an image as an ndarray
npm install @pioug/get-pixelsGiven a URL/path, grab all the pixels in an image and return the result as an ndarray. Written in 100% JavaScript, works both in browserify and in node.js and has no external native dependencies.
Currently the following file formats are supported:
- PNG
- JPEG
- GIF
``javascript
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.slice());
});
`
npm install get-pixels
Reads all the pixels from url into an ndarray.
- url is the path to the file. It can be a relative path, an http url, a data url, or an in-memory Buffer.type
- is an optional mime type for the image (required when using a Buffer)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 [width, height, channels].
Note For animated GIFs, a 4D array is returned with shape [numFrames, width, height, 4]`, where each frame is a slice of the final array.
