Struct core_graphics::image::CGImageRef

pub struct CGImageRef(_);

Implementations

impl 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

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<CGImageRef> for CGImage

fn borrow(&self) -> &CGImageRef

Immutably borrows from an owned value.

impl ToOwned for CGImageRef

type Owned = CGImage

The resulting type after obtaining ownership.

fn to_owned(&self) -> CGImage

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

Uses borrowed data to replace owned data, usually by cloning.
