Components are simply passed through unchanged. Closed contours are reversed in such a way that the first point remains the first point. cCst|SN)r)selfcontourr w/var/www/html/riverr-enterprise-integrations-main/venv/lib/python3.10/site-packages/fontTools/pens/reverseContourPen.py filterContourszReverseContourPen.filterContourN)__name__ __module__ __qualname____doc__r r r r r rs ccs|sdSt|dksJd|d}|dvsJ|dk}|d\}}|dvs0Jd||d }|d krW|dus@Jd |rFJd |dftt|dd d }|sh|dkr`d}nd}||fVn|d \}}|d }|r||fV||krd|ffV|t|dd |ff|d <t|dkr|d\} } n||} } | dkr|| kr|d=|r|t|dd | f|d <n||ffV|t|dd |ff|d <t|ddD]\\} } \} }| tt| dd |d ffVq|rdnddfVdS)z Generator that takes a list of pen's (operator, operands) tuples, and yields them with the winding direction reversed.
