Integer value that specifies the page of the PDF

Code Sample Example

This example sets the variable maxwidth to the width of page 3, and the variable maxheight to the height of page 4, of the PDF

named parts_manual.

&maxheight := pdfheight( ‘parts_manual’,4 )

Pie (procedure)

Creates a pie slice shape, which can then be rendered using stroke, fill, or strokeandfill.

Syntax

pie( x, y, radius, startangle, endangle )

Arguments

x, y

Measure values representing the horizontal/vertical position, in inches, of a circle's center representing the whole pie from

which to draw a slice.

radius

Measure value representing the length, in inches, of the segments of the pie, i.e. its radius.

startangle, endangle

Measure values representing the angles, in degrees, of both segments of the pie slice. Values increase counter clock wise,

with 0 extending right from the center of the circle.

Code Sample Example

This example draws a whole pie chart with a shadow effect.

Example

setfillcolor([0,0,0,50]) %Set shadow colour to gray

pie(1.5,1.5,1,60,290) %Create shadow for first slice

translate(0.2,0.2) %Separate shadows

pie(1.5,1.5,1,290,420) %Create shadow for second slice

fill() %Display shadows

translate(-0.3, 0.3) %Offset chart from its shadow
