This coefficient is set when a +* PcdMap is created, but may later be modified. The default value +* is zero, which gives no distortion. For pincushion distortion, +* the supplied value should be positive. For barrel distortion, it +* should be negative. +* +* Note that the forward transformation of a PcdMap applies the +* distortion corresponding to this attribute, and the inverse +* transformation removes this distortion. If a PcdMap is inverted +* (e.g. by using astInvert), then the forward transformation will +* remove the distortion and the inverse transformation will apply +* it. The distortion itself will still be given by the same value of +* Disco. +* PcdCen(axis) +* This attribute specifies the centre of a pincushion distortion. +* 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 values of 345.0 and +* -104.4 on axes 1 and 2 of the PcdMap. The default for both axes is +* zero. + +* Methods Over-Ridden: +* Public: +* None. +* +* Protected: +* astClearAttrib +* Clear an attribute value for a PcdMap. +* astGetAttrib +* Get an attribute value for a PcdMap. +* astSetAttrib +* Set an attribute value for a PcdMap. +* astTestAttrib +* Test if an attribute value has been set for a PcdMap. +* astTransform +* Apply a PcdMap to transform a set of points. + +* New Methods Defined: +* Public: +* None. +* +* Protected: +* astClearDisco +* Clear the Disco attribute value for a PcdMap. +* astGetDisco +* Get the Disco attribute value for a PcdMap. +* astSetDisco +* Set the Disco attribute value for a PcdMap. +* astTestDisco +* Test if a Disco attribute value has been set for a PcdMap. +* astClearPcdCen +* Clear the PcdCen attribute value for a PcdMap. +* astGetPcdCen +* Get the PcdCen attribute value for a PcdMap. +* astSetPcdCen +* Set the PcdCen attribute value for a PcdMap. +* astTestPcdCen +* Test if a PcdCen attribute value has been set for a PcdMap. + +* Other Class Functions: +* Public: +* astIsAPcdMap +* Test class membership. +* astPcdMap +* Create a PcdMap. +* +* Protected: +* astCheckPcdMap +* Validate class membership. +* astInitPcdMap +* Initialise a PcdMap. +* astInitPcdMapVtab +* Initialise the virtual function table for the PcdMap class. +* astLoadPcdMap +* Load a PcdMap. + +* Macros: +* None. + +* Type Definitions: +* Public: +* AstPcdMap +* PcdMap object type. +* +* Protected: +* AstPcdMapVtab +* PcdMap virtual function table type. + +* Feature Test Macros: +* astCLASS +* If the astCLASS macro is undefined, only public symbols are +* made available, otherwise protected symbols (for use in other +* class implementations) are defined.
