Help

./HomotopicAffineTransform -h

Apply homotopic affine transforma on a given image.

Example:

 HomotopicAffineTransform --input <PgmFileName> --outputDir <OutputDir> -s --a11 1.5 --a12 0.2 --a21 0.5 --a22 1.2 --tx 0 --ty 0 -m <0|1>

Usage: ./HomotopicAffineTransform [OPTIONS] 1

Positionals:

1 TEXT:FILE REQUIRED Input file.

Options:
