CurveTo/RCurveTo (procedure)

Creates a Bezier curve. Bezier curves are shapes defined using 4 points: the starting and ending points are physical posi-

tioning points while the second and third points are control points on the curve. In PlanetPress Talk, the starting point is implicit

and automatically set to the current cursor position. The first control point defines the direction the curve takes when moving

from the starting point, and before shifting to the second control point, which defines a second curve before reaching the end-

ing point.

A complete explanation of Bezier curves is beyond the scope of this document. Feel free, however, to try out this command

using the PlanetPress Talk Editor in PlanetPress in order to study its possibilities.

To draw a simple curve, use the same (x,y) coordinates for both control points.

Syntax

curveto( x1, y1, x2, y2, x3, y3 )

Arguments

x1, y1, x2, y2, x3, y3

Pairs of measure values representing the horizontal/vertical position, in inches, of each point defining the Bezier curve. When

using rcurveto, these values are relative to the current point of origin. When using curveto, they are absolute values.

Code Sample Example

This example draws a triangle with a twisted bottom side. The triangle has a blue outline and is filled with yellow.
