Sample code of Queen SDK

1. Initialize QueenEngine.

   // Build the OpenGL environment. You can skip this step if an OpenGL environment exists.
   queen::GlfwWindow* glWindow = new queen::GlfwWindow();// The OpenGL environment.
   if (!glWindow->Init(width, height, false))// A GPU driver may be not installed on your computer.
   {
    return;
   }
   // Create QueenEngine.
   // Replace rootPath with the parent directory where the queen_res folder resides. If you do not specify this parameter, the exe directory is used.
   queen_engine_t handle_beauty;
   if (QUEEN_RESULT_CODE_OK != queen_engine_create(&handle_beauty, rootPath,
   "123456"))
   {
    return;
   }

2. Enable effects and set effect parameters.

   // Enable skin smoothing.
   queen_engine_enableBeautyType(handle_beauty, kQueenBeautyTypeSkinBuffing,
   true);
   // Set the parameters for skin smoothing and image sharpening.
   queen_engine_setBeautyParams(handle_beauty,
   kQueenBeautyParamsSkinBuffing, 0.6f); // The level of skin smoothing. Valid values: [0,1].
   queen_engine_setBeautyParams(handle_beauty, kQueenBeautyParamsSharpen,
   0.8f); //// The level of image sharpening. Valid values: [0,1].

3. Process the frame image data.

   // Process the frame image data and return the processed data to the bufferOut parameter.
   if (QUEEN_RESULT_CODE_OK != queen_engine_render_with_i420(handle_beauty,
   bufferIn, width, height, bufferOut))
   {
    return;
   }

4. Destroy QueenEngine.

   // Release the engine. Make sure that the thread for processing the frame image data is used to release the engine.
   queen_engine_destory(handle_beauty);
   // Remove the OpenGL environment.
   delete glWindow;
