== Description ==
Plugin to Zoom, Pan & Rotate.
 
 

== Requirements ==
* AviSynth 2.5.8, or [http://sourceforge.net/projects/avisynth2/ 2.6.0] or greater
* Supported color formats: [[RGB32]]
 

== [[Script variables|Syntax and Parameters]] ==
:{{Template:FuncDef|Zoom (clip, string "srcx", string "srcy", string "dstx", string "dsty", string "factorX", string "factorY", string "angle", int "width", int "height", bool "show")}}
 
::{{Par2| |clip| }}
:::Input clip.
 
::{{Par2|srcx|string|""}}
::{{Par2|srcy|string|""}}
:::The "center" coordinates in the original frame.
 
::{{Par2|dstx|string|""}}
::{{Par2|dsty|string|""}}
:::The center coordinates in the moved frame
 
::{{Par2|factorX|string|""}}
::{{Par2|factorY|string|""}}
:::The magnification factors.
 
::{{Par2|angle|string|""}}
:::The rotation angle in radian.
 
::{{Par2|width|int|0}}
::{{Par2|height|int|0}}
:::The new image dimensions.
 
::{{Par2|show|bool|false}}
:::If true, it prints the calculated values on the image.
 

== Examples ==
Sounds complicated? Not really, try this:

Version().ConverttoRGB32().zoom(dstx="n", angle="n/10")

Here you see that the variable "n" can be used to reference to the current frame number (and this is of course the most important thingie).

Or try:

Version().ConverttoRGB32()
zoom(factorx="n<41 ? pow((n+1)/41,0.5) : 1", factory="n<41 ? pow((n+1)/41,0.5) : 1", dstx="n<41 ? width/2 : width/2+5*(n-41)", angle="n<41 ? 3.1415*n/10 : 0")

And the new image gets a defined alpha layer (black=transparent, else opaque), so you can layer the result on top of another video.
