VECTORHANDLE

Summary

The VECTORHANDLE structure serves as a working area for vector image manipulation and conversion. LEADTOOLS functions use this structure as a vector image handle for accessing the drawing in memory and for maintaining the characteristics of the vector image.

Note: All fields of this structure are intended for internal use. If necessary, you can refer to the LTVKRN.H header file which describes the entire structure.

Comments

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

In all cases, the values of fields in the VECTORHANDLE structure are maintained by LEADTOOLS functions.
