Why isn't there a 3D Scalar constructor? |

Could you be a bit more specific? Do you have some sample code in C++ that you would like to know how to translate? |

Ah, ok, there's no 3D Scalar in OpenCV either, I guess that explains it. I've only used python bindings before, and I was trying to make a blank NxMx3 and set the colour, I was a little confused about it requiring a scalar and there not being a 3D version (I found RGB though). |

In that case, for a Mat with only 3 channels, it simply ignores the last value of a Scalar. |
