Zooming

Zooming menu-section sets particular parameters, which are applied to screen-selection zooming respectively screen-magnifying.

Main menu item shows actual zoom level, which is applied for screen-selection and could be set between 10% and 1000%. Initial – default zoom level is 100% and this means – no zooming is performed upon screen-selection.

Example 1 – Zoom level is 100% and a part of the screen has been selected using the scissors:

The selected area appears within an area, which is transparently magnified without the zooming. Sliding the mouse-wheel upwards or downwards, selected area zoom-level can be fine adjusted to desired level interactively.

Example2 – Zoom level is 177% and the same part of the screen, as within the example 1, has been selected:

The selected area appears initially zoomed for zoom-level parameter. Sliding the mouse-wheel upwards or downwards, selected area zoom-level can be fine adjusted to desired level interactively for example on the 188%.

Menu on the selected area allows saving the tuned zoom-level as the default zoom level.

Click on the first menu item “Zoom Vidi” (“copy to”, “save to”...depending from primary use settings) allows editing initial menu level value.

Entered value can be acknowledged clicking the green button or cancelled with mouse click on the reed cancel button (respectively ENTER or ESC keys on the keyboard). Sign within the loupe icon on the left side of menu represents if actual level is positive (+), negative (-) or is reset to original selection size (O)

Desired initial zoom level can further be enlarged or shrunk by 10% or set to its original value of 100%.

1. Selected object and viewport are zoomed simultaneously – so you as user get more concentrated on the whole content of the selected and zoomed object. A ball in previous example has been enlarged together with the surrounding frame with selected

Select content parameter. This may be useful, when zooming graphics or screen objects.

2. Selected object is enlarger, but the frame remains same initial size, which is drawn as a part of selection process. When using Select viewport parameter, a golf-ball gets resized within initially declared frame. This may be useful, when defining a part of your screen as a loupe to underlying textual information.

This parameter when enabled causes the dynamic refresh (4 times per second) of selected area. If you are selecting for example a part of dynamic web site content, the selected content refreshes just like the underlying content.

After selecting an object, the selection can be moved – just like Vidi windows, in three modes. Regarding our golf-example:

1. Absolute-ball and frame are moved simultaneously in desired direction

2. Relative- ball remains on the tee, but the zooming frame moves around the ball

3. On place- frame remains on place, but the ball moves to the desired direction

When refreshing changes, the mouse buttons functions swaps. As consequence, the default moving mode from user point of view changes accordingly to refreshing or no refreshing of the selected object. Advanced user, however, still can use second mouse button during dragging to switch refreshing temporarily for the time of moving ON without changing the menu parameter.
