/**
* @example ImageFormatControl_C.c
*
* @brief ImageFormatControl_C.c shows how to apply custom image settings to
* the camera. It relies on information provided in the Enumeration_C,
* Acquisition_C, and NodeMapInfo_C examples.
*
* This example demonstrates setting minimums to offsets, X and Y, and
* maximums to width and height. It also shows the setting of a new pixel
* format, which is an enumeration type node.
*
* Following this, we suggest familiarizing yourself with the Exposure_C
* example if you haven't already. Exposure is another example on camera
* customization that is shorter and simpler than many of the others. Once
* comfortable with Exposure_C and ImageFormatControl_C, we suggest checking
* out any of the longer, more complicated examples related to camera
* configuration: ChunkData_C, LookupTable_C, Sequencer_C, or Trigger_C.

// produce erroneous results if they were to be mixed up. The first two
// functions, spinEnumerationSetIntValue() and
// spinEnumerationEntryGetIntValue(), use the integer values stored on each
// individual cameras. The second two, spinEnumerationSetEnumValue() and
// spinEnumerationEntryGetEnumValue(), use enum values defined in the
// Spinnaker library. The int and enum values will most likely be
