ANNRESIZEROTATE

Summary

The ANNRESIZEROTATE structure contains information about an annotation object when resizing and/or rotating an object in automated mode.

Syntax

typedef struct tagANNRESIZEROTATE 
{ 
   L_UINT uStructSize; 
   L_INT nState; 
   pANNXFORM pAnnXForm; 
   L_DOUBLE dAngle; 
} ANNRESIZEROTATE, *pANNRESIZEROTATE; 

Members

uStructSize

Size of the ANNCHANGEPARAM structure. Use sizeof(ANNCHANGEPARAM).

nState

Value that indicates the state of the move. Possible values are:

Value Meaning
STATE_BEGIN [1]
STATE_UPDATE [2]
STATE_END [3]

pAnnXForm

Pointer to a structure of type ANNXFORM.

dAngle

Angle of rotation in degrees. Positive is clockwise, and negative is counter-clockwise.

Comments

When doing any of the following (in automated mode or by calling L_AnnDefine explicitly)

A WM_LTANNEVENT message is sent where wParam is ANNCHANGE_RESIZE, ANNCHANGE_ROTATE, or ANNCHANGE_RESIZE_ROTATE.

The lParam field points to a structure of type ANNCHANGEPARAM. In this case, the union of ANNCHANGEPARAM is type ANNRESIZEROTATE. This message is sent when one of the following events occurs:

The pAnnXForm is a pointer to a structure of type ANNXFORM. In each of the three cases above, the ANNXFORM contains a matrix that is about to be (when bAfter is FALSE) or already has been (when bAfter is TRUE) applied to the object.
