The Zoom Button: Zoom In/Out

Pressing the Zoom button in the View Menu or the View menu of sub-windows brings up the Set Display Window pop-up. This pop-up can change the scale (zoom) the window, or set a new display region.

To change the scale, enter a factor into the Zoom Factor entry area, and press the associated Apply button. Factors greater that 1.0 will zoom out.

Alternatively, one can enter the center x and y values and width (all in microns) of a new region to display. The coordinates are relative to the origin of the displayed cell. The width is the displayed width of the region to be displayed in the window, the displayed height will depend on the drawing window's aspect ratio. Pressing the associated Apply button will redisplay the new location.

The windowing parameter entries are pre-loaded with the current window parameters, and track any changes made when the pop-up is visible.

The right mouse button (button 3) can also be used to zoom, as can the numeric keypad + and - keys which zoom in and out by a factor of two, or by ten percent if Shift is also held.

In the case where the panel is brought by from a sub-window that is displaying a cross-section, there are additional controls that allow adjustment of the vertical scaling used in the cross section display.

This control group has its own Apply button. The Auto Y-Scale check box disables the automatic vertical scaling when set. The automatic scaling maintains full view of the entire layer stack independent of the zoom factor. The Y-Scale entry allows a vertical scale factor to be entered, for use when displaying the cross section. When the Apply button is pressed, the cross-section is redrawn with the settings given. The XSectNoAutoY variable will be set or unset to reflect the state of the check box. The XSectYScale variable will be set to the scale factor if it is other than unity. See 12.9 more more information.
