### TranForward

Forward transformation defined?

#### Description:

This attribute indicates whether a Mapping 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:
The TranForward attribute of a FrameSet applies to the transformation which converts between the FrameSet’ s base Frame and its current Frame (as specified by the Base and Current 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.
