Defines the methods implemented by all image types

Required methods

fn new(path: &Path) -> Self

Creates an image object from a path

fn copy(&self) -> Self

Creates a copy of the image

fn draw(&mut self, x: i32, y: i32, width: i32, height: i32)

Draws the image at the presupplied coordinates and size

fn width(&self) -> i32

Return the width of the image

fn height(&self) -> i32

Return the height of the image

fn as_ptr(&self) -> *mut c_void

Returns a void pointer of the image, for internal use

fn as_image_ptr(&self) -> *mut Fl_Image

Retunrs a pointer of the image

fn from_image_ptr(ptr: *mut Fl_Image) -> Self

Transforms a raw image pointer to an image

fn as_bytes<'a>(&self) -> &'a [u8]

Returns the raw underlying image data
