Creating Sources

tools.sequenceBuilder contains the SequenceBuilder class which can be used to parse a filename and generate details such as start and end frames. path should be a frame from a numbered sequence and SequenceBuilder will find the start and end frames and construct a resulting path with the frame range built-in, suitable for constructing Sources from, in the form: /path/to/file.[start-end].ext.

from tools.sequenceBuilder import SequenceBuilder

# the image sequence has frames 1-999
path = "/images/sequence.0001.exr"

builder = SequenceBuilder(path)
for f in range(0, builder.frames):
    print builder.build(f)

# construct Sources using self.path, which has the frame range included
source = Source(builder.path)

print builder.path

This prints out /images/sequence.[0001-0999].exr.

Adding Sources

Sources can be added to the Project with the Project.addItem() method.
