Description Usage Arguments Details Value Author(s) Examples

View source: R/xx2swf.R

Given the file names of a sequence of images, this function can convert them into a Flash file (.swf). Supported input formats are jpg/jpeg and png. The two formats are allowed to appear in the same sequence.

1 2	image2swf(input, output = "movie.swf", bgColor = "white", interval = 1)

`input`	the file names of the images 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

This function uses the Ming library (http://www.libming.org/) to implement the conversion. If you want to create a Flash file consisting of vector graphics, use svg2swf() instead.

The name of the generated swf file if successful.
