image2swf: Convert bitmap images to SWF

In R2SWF: Convert R Graphics to Flash Animations

Convert bitmap images to SWF

Description

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.

Usage

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

Arguments

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

Details

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

Value

The name of the generated swf file if successful.
