		- `data: Buffer` - The data of the image, format depends on `type`, see below
		- `hotspot: null \| Hotspot` - If the image is a cursor (`.cur`), this is the hotspot

		The format of the `data` parameter depends on the type of image. When the image is of type `bmp`, the `data` buffer will hold raw pixel data in the RGBA order, with integer values between 0 and 255 (included). When the type is `png`, the buffer will be png data.

		The `hotspot` property will either be `null`, or an object with an `x` and `y` property.

		💡 The `png` data can be written to a file with the `.png` extension directly, or be decoded by [node-lodepng](https://github.com/LinusU/node-lodepng) which will give you the same raw format as the `bmp` type.
