CorelDRAW Help | Edit lenses

Edit lenses

After you create a lens, you can edit it. For example, you can adjust the shape of a lens by using any of the Edit Shape and Curve tools. For more information about shaping objects, see Shape objects. You can also adjust the settings of Bitmap effect lenses. For more information, see To work with bitmap effects.

You can specify how a lens affects the area beneath it. For example, you can change the viewpoint of a lens, indicated by an X in the drawing window, to display any part of a drawing. The viewpoint represents the center point of what is being viewed through the lens. You can position the lens anywhere in the drawing window, but it always shows the area around its viewpoint marker. For example, you can use the viewpoint marker on the Magnify lens to enlarge part of a map.

You can also display a lens only where it overlaps other objects or the background. As a result, the lens effect is not seen where the lens covers blank space (white space) in the drawing window.

Freezing the current view of a lens lets you move the lens without changing what’s displayed through it. In addition, changes you make to the areas beneath the lens have no effect on the view.

You can feather the edges of lens objects to blend them perfectly into the background. For more information, see Feather object edges.
