typedef struct _ANNRECT 
   L_DOUBLE left; 
   L_DOUBLE top; 
   L_DOUBLE right; 
   L_DOUBLE bottom; 

The ANNRECT structure defines coordinates of an annotation object's defining rectangle. The coordinates are interpreted using the container's scaling factors and offsets, which are described in Low-Level Coordinate System for Annotations.


pANNRECT is a pointer to an ANNRECT structure. Generally, where a function parameter type is pANNRECT, you can declare an ANNRECT variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pANNRECT variable is necessary only if your program requires a pointer.

The ANNRECT structure is like a Windows RECT structure, except that it uses double-precision floating point values.
