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
