                  FakeCamera

A fake camera.  This will emulate a camera, but instead of
accessing the hardware, it will load a series of images from file.

Method Details

init(self, pattern=None, start=0, stop=19, char='?', interval=1.0, visionSystem=None, verbose=0)
(Constructor)

pattern is a filename with indicators on where to put digits for the
sequence.  Absolute or relative filenames can be used.

For example, 'image???-.ppm' would start at 'image000.ppm'
and continue up to stop.

char is the character that should be replaced in the pattern.

interval = how often do I get new image

As an example, to load som-0.ppm through som-19.ppm, we could call
FakeCamera('vision/snaps/som-?.ppm', 0, 19)

Overrides:: pyrobot.camera.Camera.__init__

update(self)
