…s on the canvas Outline Stroke put a stroke's geometry effects, such as Offset Path or Zig Zag, on the filled outline it made, and it put the object's geometry effects on the result: the outline, or the group that holds the outlines and the fill copies. The effects then reshaped the outline: an Offset Path of 10 pt on a 4 pt stroke gave a band 24 pt wide, while the canvas offsets the path and strokes it 4 pt wide. Outline Stroke now applies the object's visible geometry effects to the path first, and then applies each stroke's own geometry effects to the path that stroke outlines, as the canvas does. A brushed stroke's art follows that path too. The filled outline of a stroke without a brush keeps the stroke's other effects, and the result keeps the object's other effects. Expand's Stroke option and Flatten Transparency's Convert All Strokes to Outlines outline strokes the same way. Docs: docs/target-app-parity.md.

Thanks @dotCooCoo. Holding this one for the project owner's call on parity: as far as public descriptions go, Illustrator's Object › Path › Outline Stroke outlines the path itself and leaves live effects out (people run Expand Appearance first to keep them), so baking geometry effects into the outline would be our own behaviour. If it goes ahead, |

Read the full diff at this head. outline_strokes now applies the object's visible geometry effects to the path first (reshaped) and then each stroke's own geometry effects to the path that stroke outlines, stripping them from the stroke afterwards so they are not applied twice, and Expand and Flatten Transparency reach the same code. The new tests render before and after for Outline Stroke, Expand with Stroke and Flatten Transparency and check the geometry effects are gone from the result. The FreeBSD build and test job passed at this head. Approving.

Outline Stroke: geometry effects reshape the path that is outlined, as on the canvas. Checklist cargo xtask ci is ticked.
outline_strokes in pathops.rs now imports reshaped from expand.rs, which has had it since storytold#2616, and the copies of reshaped and with_path that this branch added to pathops.rs are removed. The two copies were identical, so Outline Stroke and Expand behave as before.
…gradient A path whose Transform effect makes copies and that has a gradient fill or stroke is drawn on the canvas as separate copies, each painting its gradient by itself. Outline Stroke merged the copies into one path, so the gradient stretched across all of them. It now outlines the strokes of the art the canvas draws, as Expand Appearance does. Expand's Stroke option and Flatten Transparency's Convert All Strokes to Outlines change the same way.

Preserve the effect seed until copied strokes are outlined.
When has_gradient_copies(l) is true, d.reid assigns fresh IDs before outline_member_strokes evaluates each copied stroke. distort.transform takes its Random seed from the node ID, while the canvas reshapes the original node before drawing. The outlined stroke can therefore differ from the canvas rendering. Reassign IDs after stroke geometry evaluation.

What and why
Outline Stroke put a stroke's geometry effects, such as Offset Path or Zig Zag, on the filled outline it made, and it put the object's geometry effects on the result: the outline, or the group that holds the outlines and the fill copies. The effects then reshaped the outline instead of the path: an Offset Path of 10 pt on a 4 pt stroke gave a band 24 pt wide, while the canvas offsets the path and strokes it 4 pt wide. The reference app's help describes Object › Path › Outline Stroke on a page that says "Converting a Stroke to a Compound Path allows for modifying the outline of the Stroke" (Convert strokes to compound paths). The page does not say how effects are handled. This change makes the outline match what VectorCraft's canvas draws.
object.path.outlineStrokeapplies the object's visible geometry effects to the path first, and then applies each stroke's own geometry effects to the path that stroke outlines, in the order the canvas applies them. A brushed stroke's art follows that path too.docs/target-app-parity.mdhas one line for it. No command, param or reply changes, sodocs/mcp.mdis unchanged.#2616 adds the same two helpers (
reshaped,with_path) privately toexpand.rs. This branch adds them topathops.rsand does not depend on #2616.How it was tested
