How to zoom

Zoom in:

1. Move the mouse pointer to the top left-hand corner of the area you want zoomed.
2. Hold down the left mouse button and roll it down to the bottom right hand corner of the area you want zoomed. FracRove puts a zoombox on the screen that grows and shrinks according to the movement of the mouse. FracRove also displays a Zoom dialog box.
3. Release the left mouse button to fix the size of the zoom box.

4. You can move the zoombox either:

• By dragging the box to a new area. Note you cannot drop the zoom box onto itself.
• By clicking on the nudge controls of the Zoom dialog box.

5. When you have enclosed the precise area you want, click the OK button. FracRove clears the current picture, recalculates all the coordinates, and generates the new picture.

Zoom Back:

FracRove saves previous pictures in a Redo buffer. You can zoom back by selecting a previous picture from the Edit>Redo menu.
