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 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. 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).
