Argument

None

Example

This example displays the coffee_time image partially, where only a square defined by the rlineto()is visible.

moveto((2.0000/(6.6529)) * &width, (0.2000/(4.9897)) * &height)

rlineto(0, (3.0000/(4.9897)) * &height)

rlineto((3.0000/(6.6529)) * &width, 0)

rlineto(0, neg((3.0000/(4.9897)) * &height))

ClosePath (procedure)

Closes any open path and completes the current shape, if need be, by drawing a line from the last point in the shape to the

starting point. This ensures the shape is closed, thus enabling filling to take place if specified. Only closed shapes can be filled.

Syntax

closepath()

Argument

None

Code Sample Example

The first line of code sets the starting point of a triangle, the second and third lines of code draw the first and second lines (or

sides) of the triangle, the fourth line of code closes the triangle shape by implicitly issuing a moveto command.

Example

moveto(1.0,1.0)lineto(1.5,2.0)

lineto(0.5,2.0)

closepath()

fill()

Cos (function)

Returns the cosine value of the specified angle.

Syntax

cos( value ) measure value
