Hello Brent,


BP> I would like to use image segments in 3.9.

BP> the segment into a different image.
never tried across different Versions but a short example:

writing:

writeTrainingsSamples
        "write the class var TrainingsSamples to a file using ReferenceStreams"
        | rr |
        rr := ReferenceStream fileNamed: 'trainingssamples.obj'.
        rr nextPut: TrainingsSamplesFehlerkategorien  trainingsSamples .
        rr close.
        rr := nil

reading:

readTrainingsSamples
        "read the class var TrainingsSamples from a file using ReferenceStreams "
        | rr |
        rr := ReferenceStream fileNamed: 'trainingssamples.obj'.
        TrainingsSamplesFehlerkategorien  trainingsSamples:  rr next.
        rr close.
        rr := nil

hth,
