OpenMed Viewer is optionally extended by eHealthEngines' Image Manipulation Applet (IMA), an advanced JAVA applet, which adds image enhancement and manipulation.  The IMA provides features commonly found only on dedicated imaging workstations such as window width and level control, zoom, pan and rotate functions, as well as a 'magnifying glass' zoom feature for a region of special interest.  For color images, the IMA supports colour balnce adjstment as well as brightness and contrast control.
