Zoom and Pan Functions

WinPICS provides several zoom and pan functions for viewing your map and seismic displays.

Zoom tools and hot-keys

From the Map window, access the zoom functions from the Map Navigation toolbar, or the Display menu. On the Seismic window, access the zoom functionality from the Data Navigation toolbar, or the Display menu.

Icon Hot-key Name Description
<z> Zoom In  

Use your mouse to define a rectangle that outlines the area you want to zoom in on.

  1. Click the toolbar icon or hot-key. The cursor will turn into a + symbol.
  2. Left-click on the window and, without releasing the mouse button, drag the cursor diagonally to define the opposite corner of the rectangle.
  3. Release the mouse button.
<Ctrl> + <z> Zoom In (x2) Click to zoom into the map at 2x the map scale.

 Zoom Out Click to zoom out of the map at 2x the map scale.
<A> Zoom All Use the Zoom All function to view all the data on your map or seismic window. This will allow you to view an entire map, seismic line, fence, etc.
<Z> Undo Zoom Use the Undo Zoom function to return to your previous zoom level. Alternatively, you can select undo from the menu bar by selecting Display Options | Zoom | Undo.
none Zoom to Scale  

Use the Zoom Scale function to zoom to a specific scale in the Map window or Seismic window.

Follow these steps in the Map window:

  1. Select Display Options | Zoom | Scale.
  2. Enter a ratio for your map scale. For example, ‘20000’ produces a 1:20000 map scale.
  3. Click OK.

When using Zoom Scale in the Seismic window, select Display | Zoom | Scale to open the Seismic Display Options dialog box.
none <Ctrl> + <q> Zoom Square  

In the Seismic window, use the Zoom Square function to produce proportionate seismic scales that are based upon the number of traces per inch in the current display.

Open the Zoom Square function on the seismic window by selecting Display | Zoom | Square or pressing the hot-keys.

Pan across the map

  • To put the cursor in pan mode, click the  button on the Map Selection toolbar. The cursor turns to a hand symbol.
  • If you are working on a very busy map with many objects, press and hold the <Shift> key while you pan, and then release the key at the point of interest where you want the map redrawn. This speeds up your pan by preventing WinPICS from redrawing the map while you traverse it.
