TranInverseTranInverse - Inverse transformation defined?

Description:
This attribute indicates whether a MappingMapping is able to transform coordinates in the "inverse" direction (i.e. converting output coordinates back into input coordinates). If this attribute is non-zero, the inverse transformation is available. Otherwise, it is not.
Type:
Integer (boolean), readonly.
Class Applicability:
Mapping
All Mappings have this attribute.
CmpMapCmpMap
The TranInverse attribute value for a CmpMap is given by the boolean AND of the value for each component Mapping.
FrameSetFrameSet
The TranInverse attribute of a FrameSet applies to the transformation which converts between the FrameSet's current FrameFrame and its base Frame (as specified by the CurrentCurrent and BaseBase attributes). This value is given by the boolean AND of the TranInverse values which apply to each of the individual sub-Mappings required to perform this conversion. The TranInverse attribute value for a FrameSet may therefore change if a new Base or Current Frame is selected.
Notes:
  • An error will result if a Mapping with a TranInverse value of zero is used to transform coordinates in the inverse direction.
