Step-by-Step Summary

Using the Zoom In / Zoom Out Tools

Follow these steps to enlarge/reduce the image display in the RockPlot2D window using the Zoom In and Zoom Out tools.

  1. Click in the RockPlot2D window containing the image to be enlarged.
  2. Select the Zoom In button or the View | Zoom In menu command.
  3. Either:
    Position the magnifying glass button on the area to be enlarged, and click the mouse button one time for a 1.5x zoom. You'll see the zoom percent displayed in the upper magnification percentage prompt.

    Or, position the magnifying glass tool at one corner of the area to be enlarged. Depress the mouse button and drag the tool to the opposite corner.

  4. Release the mouse button when you have reached the opposite corner of the area to be enlarged.

    The program will redraw the selected area on the screen. The zoomed view will be scaled at the same vertical exaggeration as the original image. You'll see the zoom percentage updated in the magnification percentage prompt at the top of the window.

  5. Click once on the Zoom Out toolbar button (or select the View | Zoom Out menu command) to restore the active RockPlot2D window to its original scaling. The original diagram scaling is restored even if you "zoomed in" several times. Vertical Exaggeration will be preserved.

    Or, click the Zoom Undo toolbar button (or select View | Zoom Undo) to return to the previous zoom state. For example, if you've used Zoom In several times, Zoom Undo will just undo the last zoom operation.

 

Using the Magnification Prompt

Use the magnification prompt at the top of the plot window to select a pre-set magnification or to type in a specific percent.

RockPlot will apply the zoom in or out to the center of the image. You can use the scroll bars along the right and lower sides of the window to adjust the portion of the diagram that's visible.

 

Using the Magnifier Tool

You can also enlarge a small area on the current display using the magnifier button:

  1. Click on the magnifier button in the toolbar to the left . A square or rectangular pane will now appear, floating over the RockPlot image.

  2. Use your mouse to drag the pane to the area you wish to magnify.
  3. You can resize the pane by grabbing and dragging an edge or corner.
  4. You can right-click on the magnification pane to adjust the zoom amount: 0.5 X (a zoom-out mode), 2X, 3X or 4X.
  5. Turn off the magnification pane by clicking on the magnifier button again, to disable it.

Using the Utilities Add 5% Margin Tool

Follow these steps to add a margin around the entire image display in the RockPlot2D window using the add margin button.

  1. Create or open the 2D image you want to modify.
  2. Select the Add 5% Margin button RockWorks margin zoom or use the menu >Utilities >Add 5% Margin options.
  3. You will see the diagram margin change when you click the button. This is intended to give you space to add embellishments around your final map.
