Public Member Functions

 RemapBlendAction ()
 Constructor for the action.
 ~RemapBlendAction ()
virtual ActionCode Execute ()
 Executes the action. This remaps the blend node using the inverse mapping indexes it was initialised with, creating another RemapBlendAction to invert this mapping.

Static Public Member Functions

static ActionCode Init (Operation *pOp, ActionList *pActionList, NodeBlend *pNodeBlend, UINT32 RemapRef, DocCoord PosStart, DocCoord PosEnd, RemapBlendAction **NewAction)
 This is the function which creates an instance of this action. If there is no room in the undo buffer (which is determined by the base class Init function called within) the function will either return AC_NO_RECORD which means the operation can continue, but no undo information needs to be stored, or AC_OK which means the operation should continue AND record undo information. If the function returns AC_FAIL, there was not enough memory to record the undo information, and the user has decided not to continue with the operation.

Parameters:
pOp = ptr to the operation to which this action belongs [INPUTS] pActionList = ptr to action list to which this action should be added pNodeBlend = ptr to NodeBlend to change RemapRef = remap ref value to pass to pNodeBlend->Remap() IndexStart = mapping to apply to the start node IndexEnd = mapping to apply to the end node
ppNewAction = ptr to a ptr to an action, allowing the function to return [OUTPUTS] a pointer to the created action
Returns:
ActionCode, one of AC_OK, AC_NO_RECORD or AC_FAIL
This function actually performs the remapping of pNodeBlend, using pNodeBlend->Remap(). This is so that it will only function if it successfully creates the action.
Returns:
