USAGE: fxtransitions [-h or -help]

-e .... effect ....... transition effect type: blur, explode, implode, pixelize,
...................... recursion, spin, spread, swirl, zoomin, zoomout;
...................... default=blur
-f .... frames ....... number of frames in animation; frames>1; default=10
-d .... delay ........ delay between frames; delay>0; default=20
-p .... pause ........ pause delay for two undistorted input images;
...................... pause>0; default=50
-b .... bgcolor ...... background color for use only with effect=zoomout
-r ................... reverse the animation sequence and append it to the end

The two input files must be the same size.

The output file must be of type that supports multi-frames, such as gif.

If no output file is specified, the animation will be displayed automatically
but not saved to a file

PURPOSE: To create an animated transition between two images using a special effect distortion.

DESCRIPTION: FXTRANSITIONS creates an animated transition between two images using a special effect distortion. The special effects distortions include: blur, explode, implode, pixelize, recursion, spin, spread, swirl, zoomin and zoomout.

ARGUMENTS:

-e effect ... EFFECT is the type of distortion to use as the means for creating the animated transition between the two input images. The choices are: blur, explode, implode, pixelize, recursion, spin, spread, swirl, zoomin and zoomout. The default=blur.

-f frames ... FRAMES is the number of frames in the animation of each of the two input images. Values are integers > 1. The default is 10. Thus the total number of frames will be 2*frames. If the animation is reversed, then the total number of frames will be 4*frames-2.

-d delay ... DELAY between frames. Values are integers>0. The default=20

-p pause ... PAUSE is the delay to use for the first and last frame of the animation, i.e. the delay for each of the input images. The default=50

-b bgcolor ... BGCOLOR is the background color to use for fill when the effect is zoomout. Any valid IM color specification. The default=black.

-r ... If supplied, then reverse the animation sequence, remove the first and last frames of the reversed sequence and append these reversed frames to the end of the animation.
