CanvasAlgebra

The effect type that methods on this algebra produce. Represents an effect that, when run, will draw something and produce a value.

Displace img by the given landmark relative to the origin, expanding the bounding box if necessary to include the relocated image.

Get the bounding box enclosing the picture

A circle with the given diameter. We use diamter rather than radius so circle(100) has the same size as square(100)

Draws the bounding box and origin of the given picture on top of the picture. The given color is used for the bounding box and origin.

The bounding box and origin are not included in layout calculations and hence will not affect the picture's layout.

The empty shape, which is no shape at all.

Create an equilateral triangle with the given side length.

Get the height of the bounding box enclosing the picture

Expand the bounding box of img by the given amounts.

Place the origin of top on the origin of bottom

Place the origin of img at the given landmark, expanding the bounding box if necessary to include the relocated origin.

A rectangle with the given width and height.

Get the width and height of the bounding box enclosing the picture

Set the width and height of the given Drawing's bounding box to the given values. The new bounding box has the same origin as the original bounding box, and extends symmetrically above and below, and left and right of the origin.

Utility to set the width and height to the same value.

A square with the given side length.

Specify the stroke dash pattern. The pattern gives the length, in local coordinates, of opaque and transparent sections. The first element is the length of an opaque section, the second of a transparent section, and so on.

An isoceles triangle with the given width and height.
