[−][src]Function opencv::core::convert_from_buffer

pub fn convert_from_buffer(
    cl_mem_buffer: *mut c_void, 
    step: size_t, 
    rows: i32, 
    cols: i32, 
    typ: i32, 
    dst: &mut UMat
) -> Result<()>

Convert OpenCL buffer to UMat

Note: OpenCL buffer (cl_mem_buffer) should contain 2D image data, compatible with OpenCV. Memory content is not copied from clBuffer to UMat. Instead, buffer handle assigned to UMat and clRetainMemObject is called.

Parameters

  • cl_mem_buffer: source clBuffer handle
  • step: num of bytes in single row
  • rows: number of rows
  • cols: number of cols
  • type: OpenCV type of image
  • dst: destination UMat
