This is TV4ZoomPanel component for Delphi3. It was not tested 
on Delphi4 (it's possible it works on Delphi 4 too, but I not
guarantee that). It was tested by me but you use this component
on your own risk.
If you find any bugs in it, please mail me.

TV4ZoomPanel is cool, easy to use panel which displays zoom
of loaded picture (BMP or JPG format) within rectangle with 
specified width and height. Zoom may be in auto mode 
or user defined size. Width and height of zoom rectangle may be defined. Border color of zoom rectangle may be defined. Cursor visibility while zooming may be on or off.

Important properties (added to standard TPanel properties):
- AutoScale (if true then zoom factor is automatically estimated)
- HideCursor (if true then cursor is hidden while zooming)
- ZoomActive (if true then zoom rectangle is visible)
- ZoomBorderColor (border color of zoom rectangle)
- ZoomFactor (zoom factor - used only if AutoScale = false)
- ZoomPicture (picture to zoom)
- ZoomRectWidth (width of zoom rectangle)
- ZoomRectHeight (height of zoom rectangle)

If you wish I can send you sample project with TV4ZoomPanel.

This component is shareware. Read Register.txt to get information

Enjoy with TV4ZoomPanel!
