Sets the overall canvas size to be recorded with the drawing vector data.
|
|
Usually this will be specified using the same size as the canvas image.
|
|
When the vector data is saved to SVG or MVG formats, the viewbox is use to
|
|
specify the size of the canvas image that a viewer will render the vector
|
|
data on.
