The following revision refers to this bug: https://pdfium.googlesource.com/pdfium/+/f8b15f46e69fdec04a03afeb6f2bf60f90dff433 commit f8b15f46e69fdec04a03afeb6f2bf60f90dff433 Author: Nicolas Pena <npm@chromium.org> Date: Fri Mar 17 21:22:50 2017 HardClip points a bit better in fx_agg_driver In agg, the length is of type coord_type, which we have as int16. So having points bigger than the max short will not work properly.
