Convert::UUlib is a Perl interface to the uulib library (a.k.a. uudeview/uuenview).

SYNOPSIS

use Convert::UUlib :all;

# read all the files named on the commandline and decode them
# into the CURRENT directory. See below for a longer example.
LoadFile $_ for @ARGV;
for (my $i = 0; my $uu = GetFileListItem $i; $i++) {
if ($uu->state & FILE_OK) {
$uu->decode;
print $uu->filename, "n";
}
}

Read the file doc/library.pdf from the distribution for in-depth information about the C-library used in this interface, and the rest of this document and especially the non-trivial decoder program at the end.

Convert::PEM is Perl module that read/write encrypted ASN.1 PEM files.

SYNOPSIS

use Convert::PEM;
my $pem = Convert::PEM->new(
Name => "DSA PRIVATE KEY",
ASN => qq(
DSAPrivateKey SEQUENCE {
version INTEGER,
p INTEGER,
q INTEGER,
g INTEGER,
pub_key INTEGER,
priv_key INTEGER
}
));

my $pkey = $pem->read(
Filename => $keyfile,
Password => $pwd
);

$pem->write(
Content => $pkey,
Password => $pwd,
Filename => $keyfile
);

Convert::PEM reads and writes PEM files containing ASN.1-encoded objects. The files can optionally be encrypted using a symmetric cipher algorithm, such as 3DES. An unencrypted PEM file might look something like this:

-----BEGIN DH PARAMETERS-----
MB4CGQDUoLoCULb9LsYm5+/WN992xxbiLQlEuIsCAQM=
-----END DH PARAMETERS-----

The string beginning MB4C... is the Base64-encoded, ASN.1-encoded "object."
An encrypted file would have headers describing the type of encryption used, and the initialization vector:

-----BEGIN DH PARAMETERS-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,C814158661DC1449

AFAZFbnQNrGjZJ/ZemdVSoZa3HWujxZuvBHzHNoesxeyqqidFvnydA==
-----END DH PARAMETERS-----

The two headers (Proc-Type and DEK-Info) indicate information about the type of encryption used, and the string starting with AFAZ... is the Base64-encoded, encrypted, ASN.1-encoded contents of this "object."

The initialization vector (C814158661DC1449) is chosen randomly.

Sound Mural is a picture-to-sound converter plugin for Xpaint.
An image that has been loaded or composed in Xpaint is treated as a spectrogram, and the corresponding audio is written out as a WAV file.
Examples of what Sound Mural can do, can be seen and heard on the Sound Mural Web page.
To use sound mural, you need an XPaint that supports loading precompiled filters. Future official versions of XPaint might support this, but until then you can download the source here.
The modification adds a "Load Precompiled Filter" menu item to the C_Script menu. It pops open a file selection box, and you select a .so file which contains a precompiled filter, which it loads.
After it is loaded, you can run the filter from the "User Defined Filter" in the "Filters" menu. Although this modification was made to XPaint to support Sound Mural, it might be generally useful.
Your X needs to be running in 24 bit color mode or better. Otherwise it will work but performance will be bad. It is probably a good idea to use a pure white background color in XPaint.
Non-white background colors result in constant background noise in the output of Sound Mural. And pure white pixels require no processing, so it goes much faster if most of the image is pure white.
Installation and use:
Type make to compile. You must have an XPaint that has the PRECOMPILED_FILTERS feature. If you have that, then you can load this module from
Selectors -> C_Script_Editor -> File -> Load_Precompiled_Filter
After it is loaded, you invoke Sound Mural by
Filters -> User_Defined_Filter
Each time you invoke sound mural, it will render the canvas as audio, and write a WAV file to the location specified in soundmural.c. The default location is /tmp/soundmural.wav.
Enhancements:
- Sound Mural is now a freestanding command line program.
- It reads a PNG on stdin and writes WAV on stdout.
