DecimationVertical
Vertical sub-sampling of the image.

Current vertical decimation factor
Remark:
incremented by 1;
This value defines that each Nth image line in vertical direction must be sampled to build
the image. So the size of the image gets reduced in vertical direction by the factor of
DecimationVertical
. A decimation factor of 1 means no horizontal decimation. The
Height
value must be set to the requested number of lines.

exceeds the max. vertical sensor size or an error gets returned.
Example
: To get a sub sampled image which covers the whole vertical sensor height but
uses just the half number of lines you have to set the
Height
parameter to
SensorHeight
/
2 and the
DecimatinVertical
factor to 2. This will result in an image which is clinched in the
vertical direction by factor 2 but covering the whole senor in vertical direction.
OffsetX
Horizontal offset from the origin to the region of interest (in pixels).

Out:
horizontal offset
Remark:
The maximal offset equals to WidthMax – width. The offset has to be incremented by
16 pixel increments.
OffsetY
Vertical offset from the origin to the region of interest (in lines).

Remark:
The maximal offset equals to HeightMax – height. The offset has to be incremented by
2 lines.
