* Force output to be raw, uncompressed, 8-bit unsigned integer (unit8) pixel data.
* Force output to be raw, uncompressed pixel data.
* Pixel ordering is left-to-right, top-to-bottom, without padding.
* Channel ordering will be RGB or RGBA for non-greyscale colourspaces.
*
* @example
* // Extract raw RGB pixel data from JPEG input
* // Extract raw, unsigned 8-bit RGB pixel data from JPEG input
* const { data, info } = await sharp('input.jpg')
* .raw()
* .toBuffer({ resolveWithObject: true });
*
* @example
* // Extract alpha channel as raw pixel data from PNG input
* // Extract alpha channel as raw, unsigned 16-bit pixel data from PNG input
* const data = await sharp('input.png')
* .ensureAlpha()
* .extractChannel(3)
* .toColourspace('b-w')
* .raw()
* .raw({ depth: 'ushort' })
* .toBuffer();
*
* @returns {Sharp}
* @param {Object} [options] - output options
* @param {string} [options.depth='uchar'] - bit depth, one of: char, uchar (default), short, ushort, int, uint, float, complex, double, dpcomplex
