An updated version of ZoomIt v1.6 has been released. I had earlier also had posted about it when it was released.
ZoomIt is one of the tools by Mark Russinovich of Windows Sysinternals.
ZoomIt is screen zoom and annotation tool for technical presentations that include application demonstrations. ZoomIt runs unobtrusively in the tray and activates with customizable hotkeys to zoom in on an area of the screen, move around while zoomed, and draw on the zoomed images.
Its very useful for using it during the Power Point presentations.
Where the presenter can zoom a particular portion of Slide, He can highlight a portion by drawing Rectangles, Circles and can also type. So the features of highlighting part of the slide in the presentations by drawing rectangles and circles is the new feature addition.
The following image shows a portion of the Power Point Slide being Zoomed and highlighted using a rectangle.Download ZoomIt v1.6.
