typedef struct _CLIPLINE {

} CLIPLINE, *PCLIPLINE;
The CLIPLINE structure gives the driver access to a portion of a line between two clip regions used for drawing.
Members
ptfxA
Specifies the starting point of the line.
ptfxB
Specifies the end point of the line.
lStyleState
A pair of 16-bit values supplied by GDI whenever the driver calls PATHOBJ_bEnumClipLines. These two values are packed into a LONG and specify the style offset back to the first pixel of the line segment. This is the first pixel that would be rendered if the line were not clipped. This value allows the styling for the remainder of the line to be computed. Refer to Styled Cosmetic Lines for additional information.
c
Specifies the number of RUN structures in the arun array.
arun
An array of RUN structures. The RUN structures describe the start and stop portions of the clip line.
Comments
The CLIPLINE structure is used by PATHOBJ_bEnumCliplines. The CLIPLINE structure contains the original, unclipped control points of the line segment.
