The Canvas class.
A Canvas is an area mapped to a window directly under the control of the display manager. A ROOT session may have several canvases open at any given time.
A Canvas may be subdivided into independent graphical areas: the Pads. A canvas has a default pad which has the name of the canvas itself. An example of a Canvas layout is sketched in the picture below.
This canvas contains two pads named P1 and P2. Both Canvas, P1 and P2 can be moved, grown, shrinked using the normal rules of the Display manager.
Once objects have been drawn in a canvas, they can be edited/moved by pointing directly to them. The cursor shape is changed to suggest the type of action that one can do on this object. Clicking with the right mouse button on an object pops-up a contextmenu with a complete list of actions possible on this object.
A graphical editor may be started from the canvas "View" menu under the menu entry "Toolbar".
An interactive HELP is available by clicking on the HELP button at the top right of the canvas. It gives a short explanation about the canvas' menus.
A canvas may be automatically divided into pads via TPad::Divide.
At creation time, no matter if in interactive or batch mode, the canvas size defines the size of the canvas window (including the size of the window manager's decoration). To define precisely the graphics area size of a canvas in the interactive mode, the following four lines of code should be used:
and in the batch mode simply do:

Set the canvas scale in centimeters.
This information is used by PostScript to set the page size.
| [in] | xsize | size of the canvas in centimeters along X |
| [in] | ysize | size of the canvas in centimeters along Y |
if xsize and ysize are not equal to 0, then the scale factors will be computed to keep the ratio ysize/xsize independently of the canvas size (parts of the physical canvas will be unused).
if xsize = 0 and ysize is not zero, then xsize will be computed to fit to the current canvas scale. If the canvas is resized, a new value for xsize will be recomputed. In this case the aspect ratio is not preserved.
if both xsize = 0 and ysize = 0, then the scaling is automatic. the largest dimension will be allocated a size of 20 centimeters.
