  ctx.image = image

get_image(VALUE self)

Get the current image (Imlib2::Image).

Note that this function is not useful at the moment since all image instance methods blindly blow away the image and color context. So you cannot safely mix image context and image instance methods.

Example:

  im = ctx.image

image(VALUE self)

Get the current image (Imlib2::Image).

Note that this function is not useful at the moment since all image instance methods blindly blow away the image and color context. So you cannot safely mix image context and image instance methods.
