/**
 *  @example ImageFormatControl_C_Quickspin.c
 *
 *  @brief ImageFormatControl_C_Quickspin.c shows how to apply custom image
 *  settings to the camera using the QuickSpin API. QuickSpin is a subset of
 *  the Spinnaker library that allows for simpler node access and control.
 *
 *  This example demonstrates customizing offsets X and Y, width and height,
 *  and the pixel format. Ensuring custom values fall within an acceptable
 *  range is also touched on. Retrieving and setting node values using
 *  QuickSpin is the only portion of the example that differs from
 *  ImageFormatControl_C.
 *
 *  A much wider range of topics is covered in the full Spinnaker examples than
 *  in the QuickSpin ones. There are only enough QuickSpin examples to
 *  demonstrate node access and to get started with the API; please see full
 *  Spinnaker examples for further or specific knowledge on a topic.
