PcdCen(axis)PcdCenaxis - Centre coordinates of pincushion/barrel distortion

Description:
This attribute specifies the centre of the pincushion/barrel distortion implemented by a PcdMapPcdMap. It takes a separate value for each axis of the PcdMap so that, for instance, the settings "PcdCen(1)=345.0,PcdCen(2)=-104.4" specify that the pincushion distortion is centred at positions of 345.0 and -104.4 on axes 1 and 2 respectively. This attribute is set when a PcdMap is created, but may later be modified. If the attribute is cleared, the default value for both axes is zero.
Type:
Floating point.
Class Applicability:
PcdMap
All PcdMaps have this attribute.
Notes:
  • If no axis is specified, (e.g. "PcdCen" instead of "PcdCen(2)"), then a "set" or "clear" operation will affect the attribute value of both axes, while a "get" or "test" operation will use just the PcdCen(1) value.
