Three toolbar buttons allow the highlighting and hiding of graphics drawn on photographs. For this function to work, the graphics drawn must be associated with channels using the Channel ID when editing the graphics. See Photo Editing for more details on assigning the Channel ID.
The Highlight toolbar button toggles to enable or disable highlight in the photograph. When enabled, any graphic elements drawn in the photograph that have been assigned a Channel ID that match the channel selection in the Channel List will be highlighted in the highlight colour. Changing the channel selection in the Channel List will update the photograph to reflect the selection.
The Hide Others toolbar button toggles to enable or disable hiding of channels in the photo. When enabled, only the graphic elements of the channels selected in the Channel List will be displayed in the photograph.
Clicking on the Highlight Colour button will open a dialog to allow you to set the highlight colour.
