In the meantime the upstream author found the root cause for the whiskers and a workaround:
----- Forwarded message from tkl <[email protected]> ----- From: tkl <[email protected]> Subject: [mcj:tickets] #53 artifacts in PDF export To: "[mcj:tickets] " <[email protected]> Date: Thu, 01 Aug 2019 08:47:16 -0000 A minimal example is appended below; The green shape is a filled polyline with line thickness zero. Editing the shape and setting the linewidth to 1 shows that the polyline has an arrow, and part of the path is stroked twice, see the second image. The arrow is clipped against the background to remove any line protruding beyond the arrow tip, which here causes the whiskers. A remedy is to remove the arrows, either by using the update tool in xfig (click "Update", right of the "Delete" button, click on the black square in the bottom left corner, then click on the black square in the "Arrow mode" field in the bottom line below the canvas, set the arrow mode to --- (no arrows), and click on each and every green line.) Or, by using the sed-command sed '/1 \([0-9]\)$/ {s//0 \1/;N;P;d}' roof001.fig >tight.fig Beautiful tiling, by the way. The ticket remains open, because an arrow with thickness zero should not cause clipping.
