 to a specific destination. It will download the original from iCloud if necessary.
+
 If width and height is > 0, the image will be resized to a specific size and a specific compression rate. 
 If scale is below 1, the image will be scaled according to the scale-factor (between 0.0 and 1.0)
 The resizeMode is also considered.

+*Video-Support:*
+
+One can use this method also to create a thumbNail from a video in a specific size.
+Currently it is impossible to specify a concrete position, the OS will decide wich
+Thumbnail you'll get then.
+To copy a video from assets-library and save it as a mp4-file, refer to copyAssetsVideoIOS.

 The promise will on success return the final destination of the file, as it was defined in the destPath-parameter.

 ### `unlink(filepath: string): Promise<void>`
 
 Unlinks the item at `filepath`. If the item does not exist, an error will be thrown.
