LINE

This structure defines a 2D line segment represented by a start point and an end point. Each point is defined using the POINT_2D structure. It is typically used for planar geometry calculations such as boundary definitions, region drawing, or graphical path representation.

BYTE#	Field Name	Data Type	Value	Remarks
0	_tFromPoint	POINT_2D	[mm]	Start point of the line segment
8	_tToPoint	POINT_2D	[mm]	End point of the line segment

typedef struct _LINE
{
    POINT_2D _tFromPoint;   /* Start point (X1, Y1) */
    POINT_2D _tToPoint;     /* End point (X2, Y2) */
} LINE, *LPLINE;

typedef LINE LINE_2D;

Both LINE and LINE_2D refer to the same structure.
