Create Circle

There are two methods to create a circle :
Circle_rad - Creating a circle by radius size
< ButtonPress-1 >
In the canvas identifies the point for the centre of the circle.
< B1-Motion >
Creates a visual aid for the user in the form of a square which shares its centre with the circle to be created. This is controlled by movement in the x-plane.
< ButtonRelease-1 >
Identifies the outer edge of the circle, and creates the shape.
Circle_bb - Creating a circle in a bounding-box
< ButtonPress-1 >
In the canvas identifies the point for the top-left or bottom-right of a bounding-box.
< B1-Motion >
Creates a visual aid for the user in the form of a square into which the circle will fit.This is controlled by movement in the x-plane.
< ButtonRelease-1 >
Identifies the opposite corner of the box and creates the shape.


Create Rectangle

< ButtonPress-1 >
In the canvas identifies the point for the top-left or bottom-right of a bounding-box.

< B1-Motion >
Creates a visual aid for the user in the form of a square into which the rectangle will fit.This is controlled by movements in the x- and y- planes.

< ButtonRelease-1 >
Identifies the opposite corner of the box and creates the shape.


Create Polygon

< ButtonPress-1 >
In the canvas identifies a point for the polygon. At present you are allowed up to a maximum of 50 points, the server ignores any points after this.

< ButtonPress-2 >
This identifies the final point for the polygon. It closes the shape and draws it on the canvas.
NB// There is no need to explicitly close a polygon object. Pressing Mouse-button-2 does this for you.
Keep in mind that the maximum number of points that is allowed by imagemap is 50. Any more than this causes the mechanism to break down.
