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_VideoColorUYV444int_to_ARGBint(3MLIB) mediaLib Library Functions mlib_VideoColorUYV444int_to_ARGBint(3MLIB)
NAME
mlib_VideoColorUYV444int_to_ARGBint - color convert UYV interleaved to ARGB interleaved
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
void mlib_VideoColorUYV444int_to_ARGBint(mlib_u32 *ARGB, const mlib_u8 *UYV, 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 UYV pixel stream is converted into an ARGB 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:
ARGB Pointer to output buffer.
UYV Pointer to 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.
