A particular method includes detecting an interaction event using an event capture object of a rendered display of a graphics file. The graphics file is rendered to generate the rendered display by layering one or more foreground objects over one or more background objects. The method also includes executing code associated with the graphics file in response to detecting the interaction event. The code is executed to determine an identifier of a highlight object based on an identifier of the event capture object. The highlight object is below the event capture object in the rendered display and may be below the object to be highlighted in the rendered display. The code is also executed to change an attribute of the highlight object to modify the rendered display.
