svg2swf: Convert a sequence of SVG files to SWF file

In yixuan/R2SWF-archive: Convert R Graphics to Flash Animations

Description

Given the file names of a sequence of SVG files, this function could convert them into a Flash file (.swf).

Usage

  svg2swf(input, output = "movie.swf", bgColor = "white",
    interval = 1)

Arguments

input	the file names of the SVG files to be converted
output	the name of the output SWF file
bgColor	background color of the output SWF file
interval	the time interval (in seconds) between animation frames

Details

This function uses the XML package in R and a subset of librsvg (http://librsvg.sourceforge.net/) to parse the SVG file, and uses the Ming library (http://www.libming.org/) to implement the conversion. Currently this function supports SVG files created by svg() in the grDevices package, and CairoSVG() in the Cairo package.

Value

The name of the generated SWF file if successful.
