The CombineTransform function concatenates two world-to-page space transformations.
lpxformResult
Points to an XFORM structure which receives the combined-transformation.
lpxform1
Points to an XFORM structure which identifies the first transformation.
lpxform2
Points to an XFORM structure which identifies the second transformation.
The XFORM structure has the following format:
typedef struct tagXFORM /* xfrm */
{ FLOAT eM11;
FLOAT eM12;
FLOAT eM21;
FLOAT eM22;
FLOAT eDx;
FLOAT eDy;
} XFORM, *PXFORM, FAR *LPXFORM;
The return value is TRUE if the function is successful. Otherwise it is FALSE.
Applying the resulting transform has the same effect as applying the first transform and then applying the second transform.
The three transforms do not have to be distinct. For example, lpxform1 can point to the same XFORM structure as lpxformResult.
