So, why don't you just save your data as a 24-bit BMP image? Those are pretty simple format. It contains a pretty simple header, which is just a few bytes, followed by : Blue value (1 byte); Green value (1 byte); Red value (1 byte); at the end of a horizontal line, there are two zero bytes. Next line. Same thing. At the end of the file: two zero bytes. Pretty simple. You should write your own SaveBMP() function. I am thinking about writing one, because I may need it as well....
sub SaveBMP # Usage: SaveBMP($filename, $width, $height, $image_data)
{
...
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
