A `Promise` is returned when `callback` is not provided.
- `channels`: Array of channel statistics for each channel in the image. Each channel statistic contains
- `min` (minimum value in the channel)
- `max` (maximum value in the channel)
- `sum` (sum of all values in a channel)
- `squaresSum` (sum of squared values in a channel)
- `mean` (mean of the values in a channel)
- `stdev` (standard deviation for the values in a channel)
- `minX` (x-coordinate of one of the pixel where the minimum lies)
- `minY` (y-coordinate of one of the pixel where the minimum lies)
- `maxX` (x-coordinate of one of the pixel where the maximum lies)
- `maxY` (y-coordinate of one of the pixel where the maximum lies)
- `isOpaque`: Value to identify if the image is opaque or transparent, based on the presence and use of alpha channel
- `entropy`: Histogram-based estimation of greyscale entropy, discarding alpha channel if any (experimental)
@example
const image = sharp(inputJpg);

`info` contains the output image `format`, `size` (bytes), `width`, `height`,
`channels` and `premultiplied` (indicating if premultiplication was used).
When using a crop strategy also contains `cropOffsetLeft` and `cropOffsetTop`.

- `data` is the output image data.
- `info` contains the output image `format`, `size` (bytes), `width`, `height`,
`channels` and `premultiplied` (indicating if premultiplication was used).
When using a crop strategy also contains `cropOffsetLeft` and `cropOffsetTop`.
A `Promise` is returned when `callback` is not provided.

] | Rotate the output image by either an explicit angle
or auto-orient based on the EXIF `Orientation` tag.
If an angle is provided, it is converted to a valid positive degree rotation.
For example, `-450` will produce a 270deg rotation.
When rotating by an angle other than a multiple of 90,
the background colour can be provided with the `background` option.
If no angle is provided, it is determined from the EXIF data.
Mirroring is supported and may infer the use of a flip operation.
The use of `rotate` implies the removal of the EXIF `Orientation` tag, if any.
Method order is important when both rotating and extracting regions,
for example `rotate(x).extract(y)` will produce a different result to `extract(y).rotate(x)`.
@example
const pipeline = sharp()
.rotate()
.resize(null, 200)
.toBuffer(function (err, outputBuffer, info) {
// outputBuffer contains 200px high JPEG image data,
// auto-rotated using EXIF Orientation tag
// info.width and info.height contain the dimensions of the resized image
});
readableStream.pipe(pipeline);
@param {Number} [angle=auto] angle of rotation.
@param {Object} [options] - if present, is an Object with optional attributes.
