@description:
Image class provides functions that can modify the image itself.
@functions:
!fn: $load(<file_name:string>)
Load a image from the <file>.
!fn: <integer> $height()
Return the height of the image.
!fn: <integer> $width()
Return the width of the image.
!fn: $setOpacity(opacity_value:integer)
Set the image opacity; valid value are:from 0 (full transparency) to 255 (full opacity).
