## DrawTranslate

> DrawTranslate() applies a translation to the current coordinate system which moves the coordinate system origin to the specified coordinate.

The format of the DrawTranslate method is:

> void DrawTranslate ( DrawingWand *drawing_wand, const double x, const double y );

A description of each parameter follows:

drawing_wand:
  The drawing wand.

x:
  new x ordinate for coordinate system origin

y:
  new y ordinate for coordinate system origin

## DrawSetViewbox

> DrawSetViewbox() 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.
