Required Methods§

source

fn as_raw_Texture2D(&self) -> *const c_void

Provided Methods§

source

fn copy_to( &self, arr: &mut impl ToOutputArray, ddepth: i32, auto_release: bool ) -> Result<()>

Copies from OpenGL texture to host/device memory or another OpenGL texture object.

§Parameters

arr: Destination array (host or device memory, can be Mat , cuda::GpuMat , ogl::Buffer or ogl::Texture2D ).
ddepth: Destination depth.
autoRelease: Auto release mode for destination buffer (if arr is OpenGL buffer or texture).

§C++ default parameters

ddepth: CV_32F
auto_release: false

source

fn copy_to_def(&self, arr: &mut impl ToOutputArray) -> Result<()>

Copies from OpenGL texture to host/device memory or another OpenGL texture object.

§Parameters

arr: Destination array (host or device memory, can be Mat , cuda::GpuMat , ogl::Buffer or ogl::Texture2D ).
ddepth: Destination depth.
autoRelease: Auto release mode for destination buffer (if arr is OpenGL buffer or texture).
