A trait implemented by types that behave like bitmaps.

Required methods

fn get_allegro_bitmap(&self) -> *mut ALLEGRO_BITMAP[src]

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

Creates a sub-bitmap of the current bitmap. Note that the parent bitmap will panic upon destruction if any strong references to its sub-bitmaps are held at that time.

Provided methods

fn get_width(&self) -> i32[src]

fn get_height(&self) -> i32[src]

fn get_format(&self) -> PixelFormat[src]

fn get_flags(&self) -> BitmapFlags[src]

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

fn convert_mask_to_alpha(&self, mask_color: Color)[src]

fn is_compatible_bitmap(&self) -> bool[src]

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.
