About element styles

An element style defines a set of visual properties that determine the appearance of text, lines, graphic outlines, and interior fill shown in Industrial Graphics or graphic elements. An element style can be applied to a graphic that sets pre-configured visual property values that take precedence over a graphic’s native visual properties.

Element styles provide the means for developers to establish consistent visual standards in their AVEVA OMI ViewApps. An element style can define the same visual properties of text, lines, fill, and outlines for all graphics included in a ViewApp.

Likewise, element styles can be applied to a graphic during runtime to show the changing status of a piece of equipment in response to events or alarms. The following example shows an alarm border animation element style around a meter when the process value shown by the meter transitions into an alarm state.
