Implementations

impl CGContext

pub fn type_id() -> CFTypeID

pub unsafe fn from_existing_context_ptr(ctx: *mut CGContext) -> CGContext

Creates a CGContext instance from an existing CGContextRef pointer.

This funtion will internally call CGRetain and hence there is no need to call it explicitly.

This function is particularly useful for cases when the context is not instantiated/managed by the caller, but it’s retrieve via other means (e.g., by calling the method NSGraphicsContext::CGContext in a cocoa application).
