Control Decimation using GenICam API.
 Decimation
// GenICam node handle
CAM_NODE_HANDLE hDecimation = NULL;
// Decimation = 2x2
uint64_t
// Retrieve GenICam node.
Nd_GetNode(s_hCam, "DecimationHorizontal", &hDecimation);
// Nd_GetNode(s_hCam, "DecimationVertical", &hDecimation); // either will do
// Set Decimation
Nd_SetIntValue(s_hCam, hDecimation, Decimation);
Please refer to [INode functions], [IInteger node functions] in [TeliCamAPI Library manual] for more

Or write to 'Value' field of 'DecimationVertical' register to control DecimationVertical.
// Decimation = 2x2
uint32_t
// Set Decimation
Cam_WriteReg(s_hCam, 0x20213C, 1, &Decimation);
// Cam_WriteReg(s_hCam, 0x20215C, 1, &Decimation); // either will do
Please refer to [Camera functions] in [TeliCamAPI Library manual] for more detail.
