Draw Line (Not in Base Package)

Draws a line from the current pen position to the specified location in a picture. The end point is either absolute or relative to the current position, depending on the value of the absolute coordinates? input.

picture is the picture to which you want to add the line. It defaults to an empty picture.
end point is the end point of the new line. If absolute coordinates? is TRUE, the line draws to the absolute coordinate that end point specifies. If absolute coordinates? is FALSE, the line draws relative to the current pen location in picture.
x is the horizontal coordinate that increases to the right.
y is the vertical coordinate that increases to the bottom.
absolute coordinates? specifies whether the point new position is in absolute or relative coordinates. The default is absolute (TRUE).
color is the color of the pixel. The default is black. You can wire a color box constant to this input.
black in B/W? specifies whether the pixel appears as black or as white if you display it on a black-and-white monitor. The default is black (TRUE).
new picture is the modified picture.
