Constant methods for core::GpuMat

Required Methods§

source

fn as_raw_GpuMat(&self) -> *const c_void

Provided Methods§

source

fn flags(&self) -> i32

! includes several bit-fields:

the magic signature
continuity flag
depth
number of channels

source

fn rows(&self) -> i32

the number of rows and columns

source

fn cols(&self) -> i32

the number of rows and columns

source

fn step(&self) -> size_t

a distance between successive rows in bytes; includes the gap if any

source

fn dataend(&self) -> *const u8

source

fn download(&self, dst: &mut impl ToOutputArray) -> Result<()>

Performs data download from GpuMat (Blocking call)

This function copies data from device memory to host memory. As being a blocking call, it is guaranteed that the copy operation is finished when this function returns.

source

fn download_async( &self, dst: &mut impl ToOutputArray, stream: &mut Stream ) -> Result<()>

Performs data download from GpuMat (Non-Blocking call)

This function copies data from device memory to host memory. As being a non-blocking call, this function may return even if the copy operation is not finished.

The copy operation may be overlapped with operations in other non-default streams if \p stream is not the default stream and \p dst is HostMem allocated with HostMem::PAGE_LOCKED option.
