copyTo method

void copyTo(
  1. UMat dst, {
  2. UMat? mask,
})

copies those matrix elements to "m" that are marked with non-zero mask elements.

Implementation

//
//  It calls m.create(this->size(), this->type()).
void copyTo(UMat dst, {UMat? mask}) {
  cvRun(
    () => mask == null
        ? ccore.cv_UMat_copyTo(ref, dst.ref, ffi.nullptr)
        : ccore.cv_UMat_copyTo_2(ref, mask.ref, dst.ref, ffi.nullptr),
  );
}
