NAME
SWF::ForcibleConverter - Convert SWF file into version 9 format forcibly if version is under 9
SYNOPSIS
use SWF::ForcibleConverter;
my $fc = SWF::ForcibleConverter->new;
my $size = $fc->convert9($input, $output);
DESCRIPTION
SWF::ForcibleConverter is an 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.
CONSTRUCTOR
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
Buffer size (bytes) when reading input data.
At least 4096 is required, or croak.
Default is 4096.
METHOD
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.
buffer_size([$num])
This is accessor. When $num is given, it sets the member directly, without validation. Regularly, please use [get|set]_buffer_size methods.
get_buffer_size
Get buffer size.
set_buffer_size($num)
Set buffer size.
At least 4096 is required, or croak.
version($input)
Get version number of SWF file.
is_compressed($input)
Return true if $input is compressed.
uncompress($input, $output)
Convert $input SWF into uncompressed $output SWF.
This method does not change version format, simply outputs with uncompressing.
convert9($input, $output)
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, $output will be CWS as well. The another case is uncompressed, as FWS. You can call convert9_compress() or convert9_uncompress() instead.
convert9_compress($input, $output)
convert9_compress() is the same as convert9() except $output is always compressed (that is CWS).
convert9_uncompress($input, $output)
convert9_uncompress() is the same as convert9() except $output is always uncompressed (that is FWS).
