Original's table of contents

Examples

Convert formats

Convert from one format to another with quality control:

imagemagick.convert({
    srcData: fs.readFileSync('before.jpg'),
    format: 'PNG',
    quality: 100 // (best) to 1 (worst)
})
.then((buffer) => {
  fs.writeFileSync('after.png', buffer);
})
.catch((e) => {
  console.error(e);
})

Blur

Blur image:

imagemagick.convert({
    srcData: fs.readFileSync('before.jpg'),
    blur: 5
})
.then((buffer) => {
  fs.writeFileSync('after.jpg', buffer);
})
.catch((e) => {
  console.error(e);
})

Resize

Resized images by specifying width and height. There are three resizing styles:

  • aspectfill: Default. The resulting image will be exactly the specified size, and may be cropped.
  • aspectfit: Scales the image so that it will not have to be cropped.
  • fill: Squishes or stretches the image so that it fills exactly the specified size.
imagemagick.convert({
    srcData: fs.readFileSync('before_resize.jpg'),
    width: 100,
    height: 100,
    resizeStyle: 'aspectfill', // is the default, or 'aspectfit' or 'fill'
    gravity: 'Center' // optional: position crop area when using 'aspectfill'
})
.then((buffer) => {
  fs.writeFileSync('after_resize.jpg', buffer);
})
.catch((err) => {
  console.error(err);
})

Rotate, flip, and mirror

Rotate and flip images, and combine the two to mirror:

imagemagick.convert({
    srcData: fs.readFileSync('before_rotateflip.jpg'),
    rotate: 180,
    flip: true
})
.then((buffer) => {
  fs.writeFileSync('after_rotateflip.jpg', buffer);
})
.catch((err) => {
  console.error(err);
})
