<h2 id="splash">Splash</h2>
<p>by Les Hughes (leslie.hughes@rubus.com)
<h3>Description</h3>
<p>This task creates a splash screen. The splash screen is displayed for the duration of the build
and includes a handy progress bar as well. Use in conjunction with the <code>sound</code> task to
provide interest whilst waiting for your builds to complete...</p>
<h3>Parameters</h3>
<table class="attr">
  <tr>
    <th scope="col">Attribute</th>
    <th scope="col">Description</th>
    <th scope="col">Required</th>
  </tr>
  <tr>
    <td>imageurl</td>
    <td>A URL pointing to an image to display.</td>
    <td>No; defaults to <samp>antlogo.gif</samp> from the classpath</td>
  </tr>
  <tr>
    <td>showduration</td>
    <td>Initial period to pause the build to show the splash in milliseconds.</td>
    <td>No; defaults to <q>5000</q></td>
  </tr>
  <tr>
    <td>progressregexp</td>
    <td>Progress regular expression which is used to parse the output and dig out current
      progress. Exactly one group pattern must exists, and it represents the progress number (0-100)
      (i.e <q>Progress: (.*)%</q>)<br/><em>since Apache Ant 1.8.0</em></td>
    <td>No; defaults to progress increase with every action and logged output line</td>
  </tr>
  <tr>
    <td>displaytext</td>
    <td>display text presented in the splash window<br/><em>since Ant 1.8.0</em></td>
    <td>No; defaults to <q class="no-break">Building ...</q></td>
  </tr>
</table>
<h3>Deprecated properties</h3>

<p>The following properties can be used to configure the proxy settings to retrieve an image from
behind a firewall. However, the settings apply not just to this task, but to all following
tasks. Therefore they are now deprecated in preference to the <code>&lt;setproxy&gt;</code> task,
that makes it clear to readers of the build exactly what is going on.</p>
