RectStroke (procedure)

Creates and draws an empty rectangle shape. The colour of the pen used to draw the rectangle can be set using set-

strokecolor.

Syntax

rectstroke( x, y, width, height )

Arguments

x, y

Measure values representing the horizontal/vertical position, in inches, of the starting point.

width, height

Measure values representing the width/height, in inches, of the rectangle shape.

Code Sample Example

This example draws two identical rectangles.

To draw a rectangle that is both stroked and filled, use rectstroke and rectfill in succession.

Example

rectstroke(1,1,2,2) %Draw first rectangle

%Offset starting position slightly to distinguish

%between each rectangle; the second rectangle is blue.

translate(.2,.2)

setstrokecolor([100,100,0,0])

%Draw second rectangle using conventional commands

moveto(1,1) %Reset current point

lineto(3,1) %Draw first line

lineto(3,3) %Draw second line

lineto(1,3) %Draw third line

closepath() %Close shape

stroke() %Draw shape
