Implementations

impl CGImage

pub fn new(
    width: size_t,
    height: size_t,
    bits_per_component: size_t,
    bits_per_pixel: size_t,
    bytes_per_row: size_t,
    colorspace: &CGColorSpace,
    bitmap_info: u32,
    provider: &CGDataProvider,
    should_interpolate: bool,
    rendering_intent: u32
) -> Self

pub fn type_id() -> CFTypeID

Methods from Deref<Target = CGImageRef>

pub fn width(&self) -> size_t

pub fn height(&self) -> size_t

pub fn bits_per_component(&self) -> size_t

pub fn bits_per_pixel(&self) -> size_t

pub fn bytes_per_row(&self) -> size_t

pub fn color_space(&self) -> CGColorSpace

pub fn data(&self) -> CFData

Returns the raw image bytes wrapped in CFData. Note, the returned CFData owns the underlying buffer.

pub fn cropped(&self, rect: CGRect) -> Option<CGImage>

Returns a cropped image. If the rect specifies a rectangle which lies outside of the image bounds, the None is returned.

Trait Implementations

impl AsRef<CGImageRef> for CGImage

fn as_ref(&self) -> &CGImageRef

fn borrow(&self) -> &CGImageRef

Immutably borrows from an owned value.

impl Clone for CGImage

fn clone(&self) -> CGImage

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Deref for CGImage

type Target = CGImageRef

The resulting type after dereferencing.

fn deref(&self) -> &CGImageRef

Dereferences the value.

impl DerefMut for CGImage

fn deref_mut(&mut self) -> &mut CGImageRef

Mutably dereferences the value.

impl Drop for CGImage

fn drop(&mut self)
