Not being a native speaker, I think this is not a rectangle. It is a parallelogram or a rhombus / rhomboid.

For example I do not want to line including;
39.0000 38.0000
This is a coordinate pair, a point in a plane. A line needs at least one more point.

Quote:
Because it is not in the rectangle.
Should a line dissect that geometric shape, or lie entirely within?


Pls tell us how to interpret your "coordinate list".

mlib_VideoColorYUV444int_to_ABGRint(3MLIB)		    mediaLib Library Functions			mlib_VideoColorYUV444int_to_ABGRint(3MLIB)

NAME

       mlib_VideoColorYUV444int_to_ABGRint - color convert YUV interleaved to ABGR interleaved

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       void  mlib_VideoColorYUV444int_to_ABGRint(mlib_u32 *ABGR, const mlib_u8 *YUV, const mlib_u8 *A_array, mlib_u8 A_const, mlib_s32 w, mlib_s32
       h, mlib_s32 dlb, mlib_s32 slb, mlib_s32 alb);

DESCRIPTION

       The YUV pixel stream is converted into an ABGR pixel stream.  All pixel components are 8-bit unsigned integers. All buffers have dimensions
       w and h.

       The alpha values for this function work in the following fashion:

	 o  If A_array pointer is not NULL, the values are taken from there. It has to have the same dimensions as the Y buffer.

	 o  If A_array pointer is NULL, the alpha values for every pixel are set to A_const.

       The following equation is used:

       |R|   |1.1644  0.0000  1.5966|	[|Y|   | 16.0000|]
       |G| = |1.1644 -0.3920 -0.8132| * [|U| - |128.0000|]
       |B|   |1.1644  2.0184  0.0000|	[|V|   |128.0000|]

PARAMETERS

       The function takes the following arguments:

       ABGR	       Pointer to output buffer.

       YUV	       Pointer to Y input buffer.

       A_array	       Array of alpha values.

       A_const	       Constant alpha value.

       w	       Image width in pixels.

       h	       Image height in lines.

       dlb	       Linebytes for output buffer.

       slb	       Linebytes for input buffer.

       alb	       Linebytes for alpha buffer.

RETURN VALUES

       None.
