Element: layer.tile_mode

Type

numeric

Description

A policy for how graphic items are auto-annotated in graphic_window. The only layer which has this attribute is the window's annotation layer.

This attribute has a boolean value: true (1) sets the policy to be tile mode, false (0) sets the policy to be normal mode.

In normal mode, an attempt is made to label as many items in the window as possible. Normal mode is appropriate for the creation of one-off snapshot images.

In tile mode, some items may not be labelled because they would be labelled in an adjoining image. Tile mode is typically appropriate when the system is used to produce a series of seamless contiguous tiled images. In such a system graphic items which straddle tile boundaries require to be labelled once only rather than in every tile.

New windows have an initial tile mode appropriate to the system deployment: if the system is being used as a service then tile mode is the default. For stand-alone client deployment the default is normal mode.
