Nx Witness User Manual

Items (Devices, Cameras, Integrations, Virtual Cameras, Web Pages, Local files, etc.) are placed on the Viewing Grid to create a Layout. A Layout may contain more than once instance of an Item, up to a total maximum of 64 items.

Permission to Shared Layout are covered in topics about Users and Groups and Permissions Management.

To set Aspect Ratio and Spacing

Right-click on the Viewing Grid of the Layout to open the Layout context menu and select one of the following Layout Configuration choices.

•Resolution expands to offer choices of Auto, High, and Low resolutions.

•Cell Aspect Ratio expands to offer quick selection of the most common Aspect Ratios.

oCell aspect ratio is adaptive-it depends on the aspect ratio of the first item opened in the Viewing Grid. The default aspect ratio of cell in the Viewing Grid is 16:9 can be changed to other presets.

•Cell Spacing expands to offer none, small, medium, and large spacing or padding between layout elements.

Note: Cell Spacing, Cell Aspect Ratio, and Layout Resolution can be set for universally for a Layout or use the Layout Settings dialog to adjust them manually.

To change additional Layout Settings

Do one of the following:

•Right-click on the Viewing Grid where there is item of the Layout and select Layout Settings...

•Right-click on a Layout in the Resource Panel and select Layout Settings...

Settings on the General tab:

•Locked slide toggle – See Locking Layouts.

•Minimum Grid Size – Enable this parameter to control item size and placement more precisely. When an item is added to layout, it is always scaled to fit into one cell of the Viewing Grid. As more items are added to layout, the cell size is adaptively reduced so that all items can fit in the display. Cell size gets smaller with each item added, so item size gets smaller. When Minimum Grid Size is enabled, you can set an absolute Viewing Grid cell size, where the greater the value in the Width and Height fields, the more cells there are in the grid. The larger the number of cells in the grid, the smaller each cell is, and therefore the more flexibility you have in positioning items.

•Logical ID – enter a custom ID number or use the up and down arrows to define the Layout ID for quick API and integration identification and access.

oGenerate – Will assign the next available, incremental ID number. 1 if no other Layouts are in the system, or 11 if ten other Layouts exist in the system.

oReset – Clears the Logical ID field.

Settings on the Background tab are described in Layout Backgrounds.
