XFORMOBJ_bApplyXform

BOOL XFORMOBJ_bApplyXform(

IN XFORMOBJ *pxo,
IN ULONG iMode,
IN ULONG cPoints,
IN PVOID pvIn,
OUT PVOID pvOut
);

XFORMOBJ_bApplyXform applies the given transform or its inverse to the given array of points.

Parameters

pxo

Points to a XFORMOBJ structure that defines the transform to be applied to the pvIn array.

iMode

Identifies the transform and the input and output data types. This parameter can be one of the following:

Value	Meaning
XF_LTOL	Applies the transform to POINTL structures to get POINTL structures.
XF_INV_LTOL	Applies the inverse of the transform to POINTL structures to get POINTL structures.
XF_LTOFX	Applies the transform to POINTL structures to get POINTFX structures.
XF_INV_FXTOL	Applies the inverse of the transform to POINTFX structures to get POINTL structures.

cPoints

Specifies the count of points in pvIn to be transformed.

pvIn

Points to an array of input points. The format of the points is specified by the iMode parameter.

pvOut

Points to the buffer that is to receive the transformed points. The iMode parameter specifies the format of the points.

Return Value

The return value is TRUE if all points were transformed without overflow. FALSE is returned if pxo, pvIn, or pvOut are null, or if overflow occurs during the transformation.
