of the box has been set:
How an image is displayed inside an image box, depends on whether the width and/or height
It can either be used directly or through the HexaPDF::Composer#image method.
An Image box object is used for displaying an image.

def draw_content(canvas, x, y)

Draws the image onto the canvas at position [x, y]. 
def draw_content(canvas, x, y)
  canvas.image(@image, at: [x, y], width: content_width, height: content_height)
end

def empty?

Returns +false+ since the image is always drawn if it fits. 
def empty?
  false
