1.3.2 Send methods

arc ->compute:

Compute the graphical<-area from the principal representation. The graphical<-area is defined to be the bounding box of the arc.

arc ->connect_angle: line, line

Connect two lines with an arc. The arc->position of the arc will be located are the line<-intersection of the two lines. The arc<-start_angle will make the arc start at the first line. The arc<-size_angle will connect it to the second line.

This method may be used to paint and/or trees.

arc ->end_angle: num

@see arc->start_angle

arc ->geometry: x=[int], y=[int], width=[int], height=[int]

Only the X and Y parameters are used to move the arc.

arc ->initialise: radius=[int], start=[num], size=[num]

Create an arc from its radius (setting arc->size), arc->start_angle and arc->size_angle. Both angles are in degrees and measured counter-clockwise.

The default radius is determined by arc.radius. The default arc->start_angle is 0 and the default arc->size_angle is 90.

arc ->points: start_x=int, start_y=int, end_x=int, end_y=int, curvature=int

Create a bounded connection between two points. The first 4 integers describe x1,y1 and x2, y2. The last value specifies the number of pixels the line is bounded.

arc ->radius: int

Specifies both graphical->width and graphical->height.

arc ->start_angle: num

@see arc->end_angle
