VISPTP (Statement)


Draw a line connecting two points on the screen.


VISPTP <start point X coordinate>, <start point Y coordinate>, <end point X coordinate>, <end point Y coordinate>


<start point X coordinate >
Specifies the start point of the X coordinate of the line to be drawn.
<start point Y coordinate >
Specifies the start point of the Y coordinate of the line to be drawn.
<end point X coordinate >
Specifies the end point of the X coordinate of the line to be drawn.
<end point Y coordinate >
Specifies the end point of the Y coordinate of the line to be drawn.
  • The values of the X and Y coordinates are not checked. Even if they are out of the permissible drawing range, no error will result.
  • The object screen is the screen set with VISSCREEN.
  • The brightness value for drawing is the same as the brightness designated with VISBRIGHT.
  • For this instruction, a µVision board (option) is required.
