## Manipulating the Vector Visualization

The iVector tool gives you many options to manipulate your existing vector visualizations. Once you have visualized your vector data, you may rotate, flip, translate, scale, and zoom as well as modify vector properties. The following options are available for manipulating vectors.

### Translating

Translation moves an object or group of objects in a specific direction. When an object is selected, a bounding box appears around the object. For information on translating objects, see Translation.

### Adding Annotations

The following types of annotations can be added to iVector displays:

Table 16-3: Types of Vector Annotations

Table 16-3: Types of Vector Annotations
Vector Annotation Type | Description
--- | ---
Text | Single lines or multiple lines of text can be added to a visualization to provide a label or description.
Line | Straight line annotations can be added to a visualization to link labels to objects or to identify an object.
Rectangle | Rectangular annotations can be added to a visualization to identify rectangular areas.
Oval | Oval annotations can be added to a visualization to identify elliptical areas.
Polygon | Polygon annotations can be added to a visualization to identify areas bounded by a multi-sided polygon.
Freehand | Freehand annotations can be added to a visualization to identify an area.

For more information on creating and using annotations, see Adding Annotations.

### View Zoom

View Zoom allows you to zoom in or out on a specific area of the vector display area. To zoom in or out in View Zoom mode click Zoom on the toolbar. For more information on working with View Zoom, see Zooming.

### Canvas Zoom

Canvas Zoom allows you to increase or decrease the magnification of the entire display canvas (which may contain multiple views, depending on the layout) by a specified percentage. Canvas Zoom is available by selecting the pull-down percentage list from the top of the tool just under the Help menu. For more information on working with Canvas Zoom, see Zooming.
