46 Function Library
4.4.7 X Offset
Purpose
These functions set or get start pixels of image cropping per line.
Prototype

C/C++
int Hdv62_SetXOffset (UINT Number, UINT XOffset)
int Hdv62_GetXOffset (UINT Number, UINT & XOffset)
 C#
int SetXOffset (uint Number, uint XOffset)
int GetXOffset (uint Number, out uint XOffset)
 VB.Net
SetXOffset (ByVal Number as UInteger, ByVal XOffset
as UInteger) As Integer
GetXOffset (ByVal Number as UInteger, ByRef XOffset
as UInteger) As Integer
Parameters
 Number
The number of device. The allowed value is from 0 to 15.
 XOffset
The start pixels of image cropping per line as illustrated in
Figure 4-1. The XOffset coupled with Width is the cropping
parameters. The device crops sensor image if the XOffset is
larger than 0. Following criteria must be met:
 Width <= SensorWidth
 Width + XOffset <= SensorWidth
 Width needs to be multiple of 8 pixels.
Return Value
No error occurs if return value >= 0; if negative value, please refer
to Section 4.9 for error information about return codes.
