Trait Implementations

impl BitmapLike for SubBitmap

fn get_allegro_bitmap(&self) -> *mut ALLEGRO_BITMAP

fn get_width(&self) -> i32

fn get_height(&self) -> i32

fn get_format(&self) -> PixelFormat

fn get_flags(&self) -> BitmapFlags

fn get_pixel(&self, x: i32, y: i32) -> Color

fn convert_mask_to_alpha(&self, mask_color: Color)

fn is_compatible_bitmap(&self) -> bool

Returns if this bitmap is compatible with the current display. This comes into play when you have multiple displays in a single thread, and have created bitmaps for different displays. A bitmap created for one display may or may not be compatible with the other display. If the bitmap is not compatible, drawing it will be slow.

impl Drop for SubBitmap

fn drop(&mut self)

A method called when the value goes out of scope.

impl SharedBitmap for SubBitmap

fn create_sub_bitmap(&self,
                     x: i32,
                     y: i32,
                     w: i32,
                     h: i32)
                     -> Result<SubBitmap, ()>

fn get_backing_bitmap(&self) -> Option<Rc<Bitmap>>

Returns the backing bitmap, if possible.
