Description: This macro creates a perspective view of a (hyper)stack to be used in presentations or publications
Features:
  • Adjustable perspective and channel sequence
  • Option to illustrate color mixing during overlap
  • Still image can be saved with transparent background
  • Animated stack can be saved as .AVI

Macro Commands:
Create Demo Stack [1]

Creates a hyperstack to test perspective view of circular objects.

Make Perspective Animation [2]

Uses current (hyper)stack (or selection) to create perspective animation.
You can double-click the eyedropper tool to adjust foreground color (used for border) and background color before issuing this command.

Save View with Transparent Background [3]

This option is mainly intended for animations without color mixing. Current time point of animation is saved as still image in .PNG format with transparent background. Programs like PowerPoint will honor transparency, so that non-rectangular objects blend nicely with any gradient background. For adding shadow as shown in Fig 2, choose in PowerPoint: Format>Picture>Shadow

Save Animation as AVI [4]

Saves expanding stack as .avi movie. You may need to convert to other codecs when importing the movie elsewhere.
