The XFORMOBJ_bApplyXform function applies the given transform or its inverse to the given array of points.
Pointer to a XFORMOBJ structure that defines the transform to be applied to the pvIn array.
Identifies the transform and the input and output data types. This parameter can be one of the following:
| Value | Meaning |
|---|---|
| XF_INV_FXTOL | Applies the inverse of the transform to POINTFIX 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 POINTFIX structures (see GDI Data Types). |
| XF_LTOL | Applies the transform to POINTL structures to get POINTL structures. |
Specifies the count of points in pvIn to be transformed.
Pointer to an array of input points. The format of the points is specified by the iMode parameter.
Pointer to the buffer that is to receive the transformed points. The iMode parameter specifies the format of the points.
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.
