\section{Introduction}
This package provides an interface for creating PDF and SVG files with animated content from sets of graphics or image files, from inline graphics, such as \LaTeX-picture, PSTricks or pgf/TikZ generated pictures, or just from typeset text. Unlike standard movie/video formats, package `animate' allows for animating vector graphics. The result is roughly similar to the SWF (Flash) format, although not as space-efficient.
-Package `animate' supports the usual workflows for making PDF, i.\,e. pdf\LaTeX{}, Lua\LaTeX{}, \LaTeX{} $\rightarrow$ \verb+dvips+ $\rightarrow$ \verb+ps2pdf+/Distiller and \pXepLaTeX{} $\rightarrow$ \verb+(x)dvipdfmx+. For animated SVG, it supports the \verb+dvisvgm+ driver. The DVI/XDV used as input for \verb+dvisvgm+ can be generated with \LaTeX{}, Lua\LaTeX{} (in DVI mode with command `\verb+dvilualatex+') and \XeLaTeX{} (with option `\verb+--no-pdf+').

-By default, control button widgets are drawn with black strokes on transparent background. The background can be turned into a solid colour by the first option, while the second option specifies the stroke colour. The parameter \verb+<colour>+ is an array of colon-(\verb+:+)-separated numbers in the range from 0.0 to 1.0. The number of array elements determines the colour model in which the colour is defined: (1) gray value, (3) RGB, (4) CMYK. For example, `\verb+1+', `\verb+1:0.5:0.2+' and `\verb+0.5:0.3:0.7:0.1+' are valid colour specifications. Option \verb+buttonalpha+ adds transparency to the control buttons. Its parameter \verb+<opacity>+ is a number between 0.0 and 1.0, where 0.0 produces fully transparent and 1.0 fully opaque buttons.

+%With option `\verb+--optimize+', \verb+dvisvgm+ applies several optimizations to reduce the output file size.
As SVG derives from XML it is not known to be particularly economical in terms of file size. Compressed SVG, with file extension `\verb+svgz+', shortens download times and is supported by most Web browsers. It can be generated by adding option `\verb+-z+'. Also, option `\verb+--precision=1+' may be used to reduce the SVG file size. It limits the precision of floating point numbers, such as coordinates, to one decimal figure. Sometimes, animations may behave stangely after applying this option. Then, of course, it should be omitted.
