Local Zoom

Toolbar:

Menu:   View > Local Zoom

Use this command to display or hide the Local Zoom window. Local Zoom is used to to show a magnified area of an image in a separate window with a specified zoom factor. The area shown corresponds to an area in an image window or Video window currently pointed by the cursor. It can be used with drawing tools, manual measurements, calibration, etc.

When you select Local Zoom, a new window opens in ImageWarp workspace. Chose the required zoom factor from the drop-down list or type it manually. Position the cursor over an area of interest in an image frame or Video window and watch the zoomed image displayed in the Local Zoom window. If the content of the image of interest changes as a result of image processing, the magnified image will be updated as well. You can use the mouse wheel to quickly change the zoom factor.

The cross hair in the Local Zoom window shows the current cursor position which is especially useful for performing accurate manual measurements and graphic editing.

The following options are available on the top bar of the Local Zoom window:

Zoom out (- or Ctrl- or Mouse Wheel Down)

Use this command to reduce the magnification by a factor of 2.
