I wonder if the same could be done for lines? (MoveTo, LineTo, StrokePath). I
mention this because there are no improvements for the files of PDFBOX-1288 and
PDFBOX-2081.

Unfortunately not, we only disable anti-aliasing for (rectangular) filled
paths, stroked paths are always anti-aliased, so the problem with those files
must have a different cause. I remember clipping paths being an issue (if I
remember correctly, they are never anti-aliased in Java2D).

Btw, isRectangular() - shouldn't this return false for SEG_QUADTO too ?
{quote}
Well spotted, however PDF paths only use cubic beziers, so we never use
SEG_QUADTO.
