+## Crop
+
+Crops the image at a given point to a give size
+
+- @param {number} x the x coordinate to crop form
+- @param {number} y the y coordinate to crop form
+- @param w the width of the crop region
+- @param h the height of the crop region
+- @param {function(Error, Jimp)} cb (optional) a callback for when complete
+
+```js
+import jimp from 'jimp';
+
+async function main() {
+  const image = await jimp.read('test/image.png');
+
+  image.crop(150, 150);
+}
+
+main();
+```
+
+## AutoCrop
+
+AutoCrop same color borders from this image
+
+- @param {number} tolerance (optional): a percent value of tolerance for pixels color difference (default: 0.0002%)
+- @param {boolean} cropOnlyFrames (optional): flag to crop only real frames: all 4 sides of the image must have some border (default: true)
+
+or
+
+- @param {object} options object
+  - tolerance (optional): a percent value of tolerance for pixels color difference (default: 0.0002%)
+  - cropOnlyFrames (optional): flag to crop only real frames: all 4 sides of the image must have some border (default: true)
+  - cropSymmetric (optional): flag to force cropping top be symmetric. north and south / east and west are cropped by the same value
+  - leaveBorder (optional): integer of how many pixels of the background color to leave around the image
+
+```js
