Zoom in/out

Zoom in/out the area displayed on the screen.

How to Execute

left-drag Mouse on Screen

left-drag mouse over screen. This action applies when you are not in Move mode.

Screen L Drag Zooming

Dragging from bottom to top zooms in to, while dragging from top to bottom zooms out of the screen. The dragging direction for zoom in/out can be changed by preference. See Zoom Method in Preference Window/Screen page.

The left-drag area is shown as box with white dashed outline. Its width and height is shown on the lower right corner of the box. The area after zooming in/out is shown as box with light blue dashed outline.

While left-dragging, you can cancel zooming in/out by pressing Esc or right-click.

Scroll Mouse Wheel on Screen

Roll the mouse wheel back one position to zoom in the display by a factor of 2, and roll it forward to zoom out the display by a factor of 1/2. This action applies to all modes.

By default, the screen zooms in/out centers at the mouse cursor. If Shift key is held while rolling the mouse, then zooming in/out will be done with respect to the center of the display area. This behavior can be swapped. See Mouse Wheel Zoom Reference Point in Preference Window/Screen page.

Enter a Value in the Area Box

You can directly zoom in/out to a specific region by entering the region coordinates directly in the area box. This applies to all modes.

The area can be specified in the following format:

Syntax Description
<sx>,<sy>,<ex>,<ey> Specify the lower-left <sx>,<sy> and upper-right <ex>,<ey> of the region separated by comma.
(<sx>,<sy>) - (<ex>,<ey>) Specify the lower-left (<sx>,<sy>) and upper-right (<ex>,<ey>) of the region, separated by hyphen.
<x>,<y>,<size> Specify the center <x>,<y> and the width/height of the region <size> separated by comma.

The zoom region will be adjusted to the display pixel size of screen, and may differ from the specified region.
