##Image file wrapper (imagefile)
This wrapper loads images from local folder.
Parameters:
- _directory _local directory to search for files
- file-mask regular expression used for finding files in the local folder. The first group should contains the timestamp
- _extension _file extension
- time-format time format for the timestamp
- _rate _update rate
Example:
<address wrapper="imagefile">
<predicate key="directory">./images</predicate>
<predicate key="file-mask">^image(\d{12}).png$</predicate>
<predicate key="extension">png</predicate>
<predicate key="time-format">yyyyMMddHHmm</predicate>
<predicate key="rate">3600000</predicate> <!-- in milliseconds -->
</address>
<query>SELECT * FROM wrapper</query>
The output section of the virtual sensor should contain the right binary type:
<output-structure>
<field name="image" type="binary:image/png"/>
</output-structure>
