TranForwardTranForward
-
Forward transformation defined?
- Description:
- This attribute indicates whether a MappingMapping is able to transform
coordinates in the "forward" direction (i.e. converting input
coordinates into output coordinates). If this attribute is
non-zero, the forward transformation is available. Otherwise, it
is not.
- Type:
- Integer (boolean), read-only.
- Class Applicability:
-
Mapping
-
All Mappings have this attribute.
-
CmpMapCmpMap
-
The TranForward attribute value for a CmpMap is given by the
boolean AND of the value for each component Mapping.
-
FrameSetFrameSet
-
The TranForward attribute of a FrameSet applies to the
transformation which converts between the FrameSet's base
FrameFrame and its current Frame (as specified by the BaseBase and
CurrentCurrent attributes). This value is given by the boolean AND
of the TranForward values which apply to each of the
individual sub-Mappings required to perform this conversion.
The TranForward 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 TranForward value of
zero is used to transform coordinates in the forward direction.
