Vertex2f

Action

Start the operation of graphics primitives at the specified screen coordinate, in 1/16th pixel precision.

 

 

Syntax

Vertex2f x, y

 

 

Remarks

x	x-coordinate in 1/16 pixel precision (Integer)
y	y-coordinate in 1/16 pixel precision (Integer)

 

The range of coordinates can be from -16384 to +16383 in terms of 1/16 th pixel units.

The Vertex2F command allows negative coordinates. It also allows fractional coordinates, because it specifies screen (x,y) in

units of 1/16 of a pixel.

 

Please note the negative x coordinate value means the coordinate in the left virtual screen from (0, 0), while the negative y coordinate value means the coordinate in the upper virtual screen from (0, 0). If drawing on the negative coordinate position, the drawing operation will not be visible
