SWF::ForcibleConverter - Convert SWF file into version 9 format forcibly if version is under 9
use SWF::ForcibleConverter; my $fc = SWF::ForcibleConverter->new; my $size = $fc->convert9($input, $output);
SWF::ForcibleConverter is a utility that converts SWF file into version 9 format forcibly.
This program processes SWF that has version number of format less than 9. And version 9 or upper versions will be treated as it is, without converting, except compressibility change.
A reason of the changing is convenient for my algorithm, it inflates a file once. But this point does not become a problem.
The constructor new() receives hash reference as an option.
my $fc = SWF::ForcibleConverter->new({ buffer_size => 4096, });
The option has following key that is available.
Buffer size (bytes) when reading input data.
At least 4096 is required, or croak.
Default is 4096.
On the following explanation, $input or $output are file path or opened IO object.
Both are omissible. In that case, it uses STDIN or STDOUT.
As follows, this is convenient because of pipe processing.
$ cat in.swf | perl -MSWF::ForcibleConverter -e \ 'SWF::ForcibleConverter->new->convert9' > out.swf
Note that when using STDIO, uncompress() or convert9*() can be called only once.
This is accessor. When $num is given, it sets the member directly, without validation. Regularly, please use [get|set]_buffer_size methods.
Get buffer size.
Set buffer size.
Get version number of SWF file.
Return true if $input is compressed.
Convert $input SWF into uncompressed $output SWF.
This method does not change version format, simply outputs with uncompressing.
my $input = "/path/to/original.swf"; my $output = "converted.swf"; my $bytes = $fc->convert9($input, $output);
Convert $input SWF into $output SWF with changing version 9 format forcibly. And it returns size of $output.
Note that if the $input is compressed format, that is known as CWS, $output will be CWS as well. The another case is uncompressed, as FWS. You can call convert9_compress() or convert9_uncompress() instead.
convert9_compress() is the same as convert9() except $output is always compressed (that is CWS).
convert9_uncompress() is the same as convert9() except $output is always uncompressed (that is FWS).
