imageseq

Image file sequencer. More...

Image file sequencer.

The imageseq driver simulates a camera by reading an image sequence from the filesystem. The filenames for the image sequence must be numbered; e.g.: "image_0000.pnm", "image_0001.pnm", "image_0002.pnm", etc.

Note that only grayscale images are currently supported.
