Compressing A SWF With Java

The title pretty much says it all–this code sample illustrates how to compress a swf file using the Java Deflater class to perform the zlib compression on all the bytes of the swf except for the first 8 bytes which are always uncompressed. This class isn’t intelligent in the sense that it doesn’t check to see if you actually have a valid swf file signature, or check to see that the file is actually uncompressed. So basically you have swf compression in its rawest form.
