VIEW CROSSHAIRS EXAMPLE
The Zoomify Image Viewer can display crosshairs centered in the display. The HTML parameter
zCrosshairsVisible=1 will enable this effect. In addition, the Zoomify JavaScript functions Z.Utils.drawCrosshairs() and Z.Utils.hideCrosshairs()
can be used to set properties of the crosshairs and to hide them. See the Zoomify Parameter List in the Documentation folder and the Zoomify Function
in the Developer Resources folder for details.
