getBitmap

fun getBitmap(options: BitmapOptions = definedExternally): Buffer(source)

A Buffer that contains the image's raw bitmap pixel data.

The difference between getBitmap() and toBitmap() is that getBitmap() does not copy the bitmap data, so you have to use the returned Buffer immediately in current event loop tick; otherwise the data might be changed or destroyed.
