<html> <head> <title>Blinker - Transformer</title> </head> <body> <h1>Blinker - Transformer</h1> <p> The transformer module applies a transformation to each frame of a stream. The possible transformations are rotations and mirroring operations. It receives a single input stream, transforms its frames and passes it on. </p> <h2>Configuration</h2> <p> The configuration of the transformer module with name <code>NAME</code> is located in the <code>transformers/NAME</code> subdirectory. </p> <h3>Input Stream</h3> <p> The file <code>instream</code> contains the name of the stream to receive. The frames received from this stream are transformed and passed to the output stream. </p> <h3>Transformation</h3> <p> The file <code>transform</code> describes the transformation to apply. The file must contain a string from the following list: <table> <tr><td><code>none</code></td> <td width="2em"></td> <td>apply no transformation</td></tr> <tr><td><code>rotcw</code></td> <td width="2em"></td> <td>rotate 90 degrees clockwise</td></tr> <tr><td><code>rotccw</code></td> <td width="2em"></td> <td>rotate 90 degrees counter-clockwise</td></tr> <tr><td><code>rothalf</code></td> <td width="2em"></td> <td>rotate 180 degrees</td></tr> <tr><td><code>mirhor</code></td> <td width="2em"></td> <td>mirror horizontally</td></tr> <tr><td><code>mirver</code></td> <td width="2em"></td> <td>mirror vertically</td></tr> <tr><td><code>mirdiag</code></td> <td width="2em"></td> <td>mirror diagonally (\)</td></tr> <tr><td><code>mirdiag2</code></td> <td width="2em"></td> <td>mirror diagonally (/)</td></tr> </table> </p> <h3>Output Stream</h3> <p> The file <code>outstream</code> contains the name of the stream to send the transformed frames to. </p> </body> </html>
