Draw Oval (Not in Base Package)

Draws an oval in the rectangle you specify, optionally filling the interior.

picture is the picture to which you want to add the oval. It defaults to an empty picture.
rect is a cluster containing four numerics that describe the left, top, right, and bottom coordinates of the outer edges of the rectangle.
left is the horizontal coordinate of the left edge of the rectangle.
top is the vertical coordinate of the top edge of the rectangle.
right is the horizontal coordinate of the right edge of the rectangle.
bottom is the vertical coordinate of the bottom edge of the rectangle.
fill? specifies whether to fill the interior. If FALSE (default), the VI draws only the outlines.
color is the color of the lines. If the interior is filled, the VI uses this color for the interior. 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.
