Zoom is a program that allows you to magnify any portion of screen in real time: it displays images by following the mouse or by remaining stationary and it allows you also to drag custom sized areas and to instantly see them magnified.
It allows you also to do the following:
 
- Capture, magnify, resize, copy, save, print the images
- Select, copy and save colors and related values in 7 different formats (Hex, RGB, HTML, VB, C++, Delphi, Frontpage)
- Measure and select regions, lengths and angles (in pixel, cm, inch units )
- Display current cursor shape, 4 grids, 2 on screen rulers (in pixel, cm, inch units )
- Track caret ( = text insertion point) following any typed character on the centre of its window
- Freeze mouse focus or move mouse with accuracy from keyboard (at 1 pixel step)
- Handy dock to screen borders, full screen view, hide titlebar
- Paint on the screen (!) or edit images by highlighting, magnifying, underlining, adding symbols, backgrounds etc.
  and by recording and playing changes in a sequenced slide show, like a movie
