Hi all,
<p>I have made a small Programmable Filter that converts my input
data. Now I have one parameter (resolution) that I would like to
be modifiable by the user. My script currently looks as follows:</p>
<pre style="margin:0px;text-indent:0px"><span style="font-family:monospace">resolution = 20
val </span><span style="font-family:monospace;color:rgb(102,102,102)">=</span><span style="font-family:monospace"> {</span><span style="font-family:monospace;color:rgb(186,33,33)">'resolution'</span><span style="font-family:monospace">: resolution, </span><span style="font-family:monospace;color:rgb(186,33,33)">'self'</span><span style="font-family:monospace">: </span><span style="font-family:monospace;color:rgb(0,128,0)">self</span><span style="font-family:monospace">}</span></pre>
<pre style="margin:0px 0px 12px;text-indent:0px"><span style="font-family:monospace;color:rgb(0,128,0)">execfile</span><span style="font-family:monospace">(</span><span style="font-family:monospace;color:rgb(186,33,33)">'/path/to/filter.py'</span><span style="font-family:monospace">, val)
</span><span style="font-family:monospace"></span>
</pre>
Ideally I want my users to not have to replace the 20 by whatever
value they desire, but instead make a Custom Filter with either a
text input field or a slider that will pipe its value to the
Programmable Filter. Is something like this possible at all?<br>
<br>
Thanks in advance for your help,<br>
Arno<br>
