CombineTransform function (wingdi.h)
The CombineTransform function concatenates two world-space to page-space transformations.
Syntax
BOOL CombineTransform(
[out] LPXFORM lpxfOut,
[in] const XFORM *lpxf1,
[in] const XFORM *lpxf2
);
Parameters
[out] lpxfOut
A pointer to an XFORM structure that receives the combined transformation.
[in] lpxf1
A pointer to an XFORM structure that specifies the first transformation.
[in] lpxf2
A pointer to an XFORM structure that specifies the second transformation.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Remarks
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.
