Simple animation going through a sequence of bitmaps loaded in the FL Studio Visualizer.
Just go to the 'Bitmaps' tab in the Visualizer Settings Dialog :
http://www.image-line.com/support/FLH...
... and add the bitmap(s) you want to use.
After that you can for instance use the VideoBox script and animate the Custom
Bitmap index to browse through the bitmaps. Here's a simple animation of a couple
of XMas pictures.
