DESCRIPTION
<br>
</b>
</font>
The command BLUR (short form: BLU) will blur (soften) the image in the main
window. The color of each pixel in the main window will be replaced with the
averaged color of
<br><br>
width x height
<br><br>
pixels surrounding this pixel. The original color of this pixel will be
used too, weighted equally as all other pixels. The contrast will be reduced.
Larger blur rectangle will result in softer image. The textual content of
the main window (titles, labels) will remain unchanged. Default blur
rectangle width and height: 3x3 pixels (see the configuration file,
<a href="../config/index.html">
.garlicrc
</a>
).
<br><br>
Use the command BLUR OFF (short form: BLU OFF) to switch blur off.
