Detailed Description
An planar pixel representation of the world.PixMap is a pixel-based map which can be used as a background map for a GUI for instance. The data is encoded as pixels with rgb values.

Function Documentation
| void orca::PixMap::subscribe | ( | PixMapConsumer * | subscriber | ) | throw ( SubscriptionFailedException) [inherited] |
Mimics IceStorm's subscribe(). subscriber is typically a direct proxy to the consumer object. The implementation may choose to implement the push directly or use IceStorm. This choice is transparent to the subscriber. The case when the subscriber is already subscribed is quietly ignored.

- unsubscribe
| void orca::PixMap::unsubscribe | ( | PixMapConsumer * | subscriber | ) | [inherited] |
Unsubscribe an existing subscriber. The case when the subscriber is not subscribed is quietly ignored.

- subscribe
Variable Documentation
Frame2d orca::PixMapData::offset [inherited] |
Transformation from the global (arbitrarily defined) coordinate system (CS) to the CS of the pixmap. The pixmap CS is defined as as follows:
- origin at the bottom-left corner
- X axis along the bottom edge to the right
- Y axis along the left edge up Example: if the global CS starts in the middle of a pixmap and there are no rotations, then the pixmap offset is (-width/2, -height/2, 0).
