C++ (Cpp) Texture2D::copyFrom Examples

Example #1

File: opengl_interop.cpp Project: liuyq/opencv

    int get_texture(cv::ogl::Texture2D& texture)
    {
        if (!m_cap.read(m_frame_bgr))
            return -1;

        cv::cvtColor(m_frame_bgr, m_frame_rgba, CV_RGB2RGBA);

        texture.copyFrom(m_frame_rgba);

        return 0;
    }

Example #2

File: opengl_interop.cpp Project: ArkaJU/opencv

    int get_frame(cv::ogl::Texture2D& texture, cv::ogl::Buffer& buffer, bool do_buffer)
    {
        if (!m_cap.read(m_frame_bgr))
            return -1;

        cv::cvtColor(m_frame_bgr, m_frame_rgba, COLOR_RGB2RGBA);

        if (do_buffer)
            buffer.copyFrom(m_frame_rgba, cv::ogl::Buffer::PIXEL_UNPACK_BUFFER, true);
        else
            texture.copyFrom(m_frame_rgba, true);

        return 0;
    }
