Status: Stable

Note: this release has some API changes.

1. The ObjLoc_t struct now returns angle as a double rather than as an int. The value represents degrees, rather than 10*degrees.

2. The ini-file name has been changed from leaf.ini to mavis.ini. There are a number of new ini-file parameters and some with changed names. The ini file is now required to run mavis.

Other Changes:

Added H-Lines functionality for obstacle avoidance and to facilitate mapping.

Added frame forwarding so mavis can pass raw video frames from framecap to the client application for processing.

A new (optional) dll, bmpUtils.dll, is available to help pack and unpack raw frame data into an rgb array. It also has functions for reading and writing bitmaps.

Added a method for telling mavis about changes to the camera's tilt angle.

The ini file is now completely self documenting (I hope) via inlined comments. Comment lines start with #.

Mavis now writes a log of what it's doing. Both text data and bitmap files are logged. The log is managed for size, so it won't grow indefinitely.

There are two new workspaces. The first, examples, contains example code for using the mavis API. The second, utils, contains utilities that aren't directly part of mavis.
