OOF2: The Manual

The Viewer Toolbox, shown in Figure 4.6, changes the scale of the Canvas display. When the Toolbox is open, clicking the mouse on the Canvas with either the Shift or Control keys held down zooms in or out about the clicked point. The point under the mouse does not move.^[8]

Figure 4.6. The Viewer Toolbox

The Toolbox area itself displays the coordinate of the mouse click in both the pixel and physical coordinate systems of the topmost displayed Microstructure, Image, Skeleton, or Mesh.

The buttons marked In, Out, and Fill Window have exactly the same the same behavior as the items in the Zoom submenu in the Graphics Window's Settings menu. The In and Out buttons zoom about the center of the Canvas.

The Canvas Info button prints some possibly useful information about the Canvas. It reports the physical coordinates of visible region of the Canvas, the positions of the Canvas's horizontal and vertical scroll bars (in screen pixel units), and the scale factor (“Pixels per unit”) for converting between physical and screen pixel coordinates.
