Pattern strokes are written as the pattern's tiles clipped to the stroke's outline (dashes, caps, profile, arrowheads and alignment included) instead of mid-grey; freeform gradients on fills, strokes and type as an image of their colour field at the document raster effects resolution, clipped to what they paint, instead of their average colour. Both read back within 2% of the canvas at 150 ppi with no warning. Text strokes are covered for cap, miter limit, dash array and alignment; knockout groups keep their soft-masked form with a warning. The freeform box and grid sampling are shared with the renderer. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
