Image Rotation Filter Plugin

The foglamp-filter-rotate plugin allows the user to specify an angle of rotation of either 90, 180 or 270 degrees clockwise. All image data points will then be rotated by that angle.

When adding a rotate filter to either the south or north, via the Add Application option of the user interface, a configuration page for the filter will be shown as below;


Select the desire angle of clockwise rotation to be applied to the image datapoints within the readings.

Click on the Enabled option and then click on Done to add the filter.
