pub struct Surface<'a> { // some fields omitted }
Methods
impl<'a> Surface<'a>
[src]
unsafe fn from_ll<'b>(raw: *mut SDL_Surface) -> Surface<'b>
fn new(width: u32, height: u32, format: PixelFormatEnum) -> SdlResult<Surface<'static>>
Creates a new surface using a pixel format.
Example
use sdl2::pixels::PixelFormatEnum; use sdl2::surface::Surface; let surface = Surface::new(512, 512, PixelFormatEnum::RGB24).unwrap();
fn from_pixelmasks(width: u32, height: u32, masks: PixelMasks) -> SdlResult<Surface<'static>>
Creates a new surface using pixel masks.
Example
use sdl2::pixels::PixelFormatEnum; use sdl2::surface::Surface; let masks = PixelFormatEnum::RGB24.into_masks().unwrap(); let surface = Surface::from_pixelmasks(512, 512, masks).unwrap();
fn from_data(data: &'a mut [u8], width: u32, height: u32, pitch: u32, format: PixelFormatEnum) -> SdlResult<Surface<'a>>
Creates a new surface from an existing buffer, using a pixel format.
fn from_data_pixelmasks(data: &'a mut [u8], width: u32, height: u32, pitch: u32, masks: PixelMasks) -> SdlResult<Surface<'a>>
Creates a new surface from an existing buffer, using pixel masks.
fn load_bmp_rw(rwops: &mut RWops) -> SdlResult<Surface<'static>>
fn load_bmp<P: AsRef<Path>>(path: P) -> SdlResult<Surface<'static>>
Methods from Deref<Target=SurfaceRef>
fn raw(&self) -> *mut SDL_Surface
fn width(&self) -> u32
fn height(&self) -> u32
fn pitch(&self) -> u32
fn size(&self) -> (u32, u32)
fn rect(&self) -> Rect
fn pixel_format(&self) -> PixelFormat
fn with_lock<R, F: FnOnce(&[u8]) -> R>(&self, f: F) -> R
Locks a surface so that the pixels can be directly accessed safely.
fn with_lock_mut<R, F: FnOnce(&mut [u8]) -> R>(&mut self, f: F) -> R
Locks a surface so that the pixels can be directly accessed safely.
fn without_lock(&self) -> Option<&[u8]>
Returns the Surface's pixel buffer if the Surface doesn't require locking (e.g. it's a software surface).
fn without_lock_mut(&mut self) -> Option<&mut [u8]>
Returns the Surface's pixel buffer if the Surface doesn't require locking (e.g. it's a software surface).
fn must_lock(&self) -> bool
Returns true if the Surface needs to be locked before accessing the Surface pixels.
fn save_bmp_rw(&self, rwops: &mut RWops) -> SdlResult<()>
fn save_bmp<P: AsRef<Path>>(&self, path: P) -> SdlResult<()>
fn set_palette(&mut self, palette: &Palette) -> SdlResult<()>
fn enable_RLE(&mut self)
fn disable_RLE(&mut self)
fn set_color_key(&mut self, enable: bool, color: Color) -> SdlResult<()>
fn color_key(&self) -> SdlResult<Color>
The function will fail if the surface doesn't have color key enabled.
fn set_color_mod(&mut self, color: Color)
fn color_mod(&self) -> Color
fn fill_rect(&mut self, rect: Option<Rect>, color: Color) -> SdlResult<()>
fn fill_rects(&mut self, rects: &[Option<Rect>], color: Color) -> SdlResult<()>
fn set_alpha_mod(&mut self, alpha: u8)
fn alpha_mod(&self) -> u8
fn set_blend_mode(&mut self, mode: BlendMode) -> SdlResult<()>
The function will fail if the blend mode is not supported by SDL.
fn blend_mode(&self) -> BlendMode
fn set_clip_rect(&mut self, rect: Option<Rect>) -> bool
Sets the clip rectangle for the surface.
If the rectangle is None
, clipping will be disabled.
fn clip_rect(&self) -> Option<Rect>
Gets the clip rectangle for the surface.
Returns None
if clipping is disabled.
fn convert(&self, format: &PixelFormat) -> SdlResult<Surface<'static>>
Copies the surface into a new one that is optimized for blitting to a surface of a specified pixel format.
fn blit<S: AsMut<SurfaceRef>>(&self, src_rect: Option<Rect>, dst: S, dst_rect: Option<Rect>) -> SdlResult<Option<Rect>>
Performs surface blitting (surface copying).
Returns the final blit rectangle, if a dst_rect
was provided.
unsafe fn lower_blit<S: AsMut<SurfaceRef>>(&self, src_rect: Option<Rect>, dst: S, dst_rect: Option<Rect>) -> SdlResult<()>
Performs low-level surface blitting.
Unless you know what you're doing, use blit()
instead, which will clip the input rectangles.
This function could crash if the rectangles aren't pre-clipped to the surface, and is therefore unsafe.
fn blit_scaled<S: AsMut<SurfaceRef>>(&self, src_rect: Option<Rect>, dst: S, dst_rect: Option<Rect>) -> SdlResult<Option<Rect>>
Performs scaled surface bliting (surface copying).
Returns the final blit rectangle, if a dst_rect
was provided.
unsafe fn lower_blit_scaled<S: AsMut<SurfaceRef>>(&self, src_rect: Option<Rect>, dst: S, dst_rect: Option<Rect>) -> SdlResult<()>
Performs low-level scaled surface blitting.
Unless you know what you're doing, use blit_scaled()
instead, which will clip the input rectangles.
This function could crash if the rectangles aren't pre-clipped to the surface, and is therefore unsafe.
