3  <title>The visualisation project web frontend - generating paper tape images</title>
7<h2>The Paper Tape Project -- The Visualisation Web frontend project</h2>
10   This is a web frontend to the visualisation subproject. It uses
11   PHP and Ajax and is capable to render files up to several
12   Megabytes (afterwards the generated graphic files get very, very
13   huge). Like all the visualisation programs, it is highly
14   configurable (every detail you can change at the LOCHSTREIFEN
15   object can be changed in the HTML form). Thus the
16   HTML form is quite complex, but very friendly to DAUs
17   (a german expression for "PEBKAC") due to the ability to fold
18   the huge form. It should be running stable but hasn't
19   really been tested so far. Thanks to caching every generated image
20   it should even stand very much rendering requests.
24        <li>Generates <b>PNG</b> and <b>SVG</b> pictures</li>
25        <li>Takes data by
26     <ul>
27            <li>HTTP file upload up to 500kb</li>
28                <li>direct textarea input in various codes like hex array,
29                    binary, decimal, octal, IBM hex, etc.</li>
30                <li>label generator (interface to the font subproject)</li>
31        </ul>
32        <li><b>Size</b> of picture can be estimated by constant width,
33            constand height or diameter of the holes</li>
34        <li><b>Alignment</b> and mirroring of paper tape can be selected
35            graphically</li>
36        <li>All paper tape components can be dis/enabled for drawing</li>
37        <li><b>Nullbytes</b> (with value 0x00) can be attached to the front or
38            end of the file</li>
39        <li>System will <b>Generate HTML reports</b> with all parameters
40            and raw data in a nice layout</li>
41        <li>Server side <b>buffering</b> of output data</li>
45<p>Work is shared between two files:</p>
47  <li><a href="index.html">index.html</a> displays the big form with CSS
48      design and JavaScript interaction</li>
49  <li><a href="generator.php">generator.php</a> calls the cli visualisation
50      backend (translates HTTP GET variables to command line arguments in a
51          secure way) and stores the results in a temporary directory together
52          with a report HTML file where the parameters for the generated picture
53          are saved.</li>
