rsz v0.2.3

rsz

Resize image files or Buffers

Depends on node-canvas which has special build instructions as it requires Cairo to be installed on your system.

API

There is one method but multiple ways to use it:

rsz(src, width, height, function (err, buf) { /* */ })

Where src is a String specifying the path to the image or a Buffer containing the image data, and buf is a Buffer containing the resized image data.

rsz(src, width, height, dst, function (err) { /* */ })

Where src is a String specifying the path to the image or a Buffer containing the image data, and dst is a String specifying the path to write the output file to.

rsz(src, { width: w, height: h }, function (err, buf) { /* */ })

Where w and h are the width and height respectively, src is a String specifying the path to the image or a Buffer containing the image data, and buf is a Buffer containing the resized image data.

rsz(src, { width: w, height: h }, dst, function (err) { /* */ })

Where w and h are the width and height respectively, src is a String specifying the path to the image or a Buffer containing the image data, and dst is a String specifying the path to write the output file to.

Example

var rsz = require('rsz')
  , fs  = require('fs')

rsz('/path/to/nyancat.gif', 200, 350, function (err, buf) {
  fs.writeFileSync('/path/to/nyancat_200_350.gif', buf)
})

// or

rsz('/path/to/nyancat.gif', 200, 350, '/path/to/nyancat_200_350.gif', function (err) {
})

// or

rsz('/path/to/nyancat.gif', { width: 200, height: 350 }, function (err, buf) {
  fs.writeFileSync('/path/to/nyancat_200_350.gif', buf)
})

// or

rsz('/path/to/nyancat.gif', { width: 200, height: 350 }, '/path/to/nyancat_200_350.gif', function (err) {
})
