CombineTransform info Overview Group

The CombineTransform function concatenates two world-space to page-space transformations.

BOOL CombineTransform(

LPXFORM lpxformResult,	// pointer to combined transformation
CONST XFORM *lpxform1,	// pointer to first transformation
CONST XFORM *lpxform2	// pointer to second transformation
);

Parameters

lpxformResult: Points to an XFORM structure that receives the combined transformation.
lpxform1: Points to an XFORM structure that identifies the first transformation.
lpxform2: Points to an XFORM structure that identifies the second transformation.

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Applying the combined transformation has the same effect as applying the first transformation and then applying the second transformation.

The three transformations need not be distinct. For example, lpxform1 can point to the same XFORM structure as lpxformResult.
