[Copilot]

In PlatformDrawPath, the stroke Paint's Shader is only set when _shader != null, but it is never cleared when _shader is null. If a previous draw set a gradient shader, subsequent non-gradient strokes can accidentally keep using the old shader (especially in scenarios where callers draw multiple paths without a state restore). Consider explicitly clearing the shader (SetShader(null)) in the else path, or moving shader application into state so SaveState/RestoreState reliably restores it.

Issue: #21983 - GradientBrushes are not supported on Shape.Stroke
PR: #22208 - Added a support for GradientBrushes on Shape.Stroke
Author: kubaflo
Platforms Affected: Android, iOS (Windows excluded - future work)
Files Changed: 3 implementation files, 3 test files, 2 snapshot baselines

Issue Summary

When applying a LinearGradientBrush or RadialGradientBrush to the Stroke property of a Shape (Path, Ellipse, etc.), only the first color of the gradient was applied (as if it were a SolidColorBrush). Fill and Background gradients worked correctly. This was a regression from Xamarin.Forms.

Fix Approach

The PR uses a layered approach:

1. ShapeDrawable.cs (cross-platform): Calls canvas.SetFillPaint(stroke, dirtyRect) before DrawPath, so the paint state includes gradient info when drawing strokes.
2. PlatformCanvas.cs (Android): In PlatformDrawPath, applies _shader (set by SetFillPaint) to StrokePaintWithAlpha before drawing.
3. PlatformCanvas.cs (MaciOS): In PlatformDrawPath, when _gradient != null, uses FillWithGradient with ReplacePathWithStrokedPath() to convert the stroke to a filled outline and fill it with the gradient.

⚠️ Final Recommendation: REQUEST CHANGES

Summary

PR #22208 implements GradientBrush support on Shape.Stroke for Android and iOS/macOS, fixing issue #21983. The approach is conceptually sound and the screenshot baseline images confirm the visual result is correct. However, there are two code quality issues that should be addressed before merging: an Android state management bug that could cause gradient bleed between consecutive non-gradient strokes, and a wrong test namespace that breaks test organization.

Root Cause

The DrawStrokePath method in ShapeDrawable previously only called canvas.StrokeColor = stroke.ToColor(), which resolves a GradientBrush to just its first color (via ToColor()). The fix adds canvas.SetFillPaint(stroke, dirtyRect) which passes the full gradient paint state to the platform canvas before DrawPath is called. Each platform canvas then uses that gradient state during stroke drawing:

• Android: Applies _shader to StrokePaintWithAlpha in PlatformDrawPath
• iOS/macOS: Converts the path to a stroked outline via ReplacePathWithStrokedPath() then fills it with FillWithGradient

Issues Found

1. ⚠️ Android: Shader not cleared for non-gradient strokes (potential regression)

File: src/Graphics/src/Graphics/Platforms/Android/PlatformCanvas.cs:550-554

// Current code (PR):
if (_shader != null)
{
    CurrentState.StrokePaintWithAlpha.SetShader(_shader);
}
_canvas.DrawPath(platformPath, CurrentState.StrokePaintWithAlpha);

When _shader == null (solid color stroke), StrokePaintWithAlpha.SetShader() is never called. If a previous draw call set a gradient shader on StrokePaintWithAlpha, that shader persists. RestoreState() disposes _shader (sets it to null) but does not clear the shader reference on StrokePaintWithAlpha. This means a solid-color stroke rendered after a gradient stroke on the same canvas could accidentally inherit the old gradient.

Suggested fix:

var strokePaint = CurrentState.StrokePaintWithAlpha;
strokePaint.SetShader(_shader != null ? _shader : null);  // Always set (clears if null)
_canvas.DrawPath(platformPath, strokePaint);

Or use the Copilot-suggested else { strokePaint.SetShader(null); } pattern.

2. ⚠️ Wrong test namespace (breaks test organization)

File: src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue21983.cs:6

// Current (wrong):
namespace Microsoft.Maui.AppiumTests.Issues

// Expected (correct):
namespace Microsoft.Maui.TestCases.Tests.Issues

All other tests in Tests/Issues/ use Microsoft.Maui.TestCases.Tests.Issues. Using the wrong namespace may cause test runners to not discover or categorize the test correctly with the rest of the Issues test suite.

3. ℹ️ Minor: Missing newline at end of test file

File: src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue21983.cs - No \n at end of file.

4. ℹ️ Windows not implemented

The PR adds a TODO comment and #if !WINDOWS guard on the test. This is acceptable for an initial implementation, but Windows support remains absent (noted by reviewer jsuarezruiz).

Fix Quality Assessment

The core fix approach is correct and the visual results are confirmed by the screenshot baselines in the PR. The platform implementations use appropriate native mechanisms (Android shader, iOS/macCatalyst stroked path fill). The main concern is the Android state management gap that could cause regressions in mixed gradient/solid-color rendering scenarios.

Gate Result

⚠️ PARTIAL - Tests confirmed to FAIL without fix (bug correctly reproduced). "With fix" run was blocked by Android emulator infrastructure failure (ADB0010: Broken pipe) — environment issue, not a code problem. try-fix phase skipped due to Gate not completing.

Requested Changes

1. Fix Android shader clearing: Add else { CurrentState.StrokePaintWithAlpha.SetShader(null); } in PlatformDrawPath to prevent gradient shader bleed.
2. Fix test namespace: Change Microsoft.Maui.AppiumTests.Issues → Microsoft.Maui.TestCases.Tests.Issues.
3. Add newline: Add trailing newline to Issue21983.cs.

Title: ✅ Good

Current: Added a support for GradientBrushes on Shape.Stroke

Description: ⚠️ Needs Update

• Grammar: "Added a support" — git commit titles use imperative mood ("Add", not "Added a")
• Missing platform prefix — Windows is not fixed (still has a TODO for Windows in ShapeDrawable.cs), so this PR is Android + iOS/macCatalyst only
• Vague: doesn't call out which control category (Shape)

✨ Suggested PR Description

[!NOTE]
Are you waiting for the changes in this PR to be merged?
It would be very helpful if you could test the resulting artifacts from this PR and let us know in a comment if this change resolves your issue. Thank you!

Root Cause

ShapeDrawable.DrawStrokePath had a TODO comment acknowledging that Paint (gradient) support was missing for Shape.Stroke. The method called canvas.StrokeColor = stroke.ToColor(), which extracts only the first color stop from any GradientBrush, effectively reducing it to a solid color. canvas.SetFillPaint() — the mechanism that configures gradient shaders on each platform — was never called for stroke paths, so gradient brushes on Stroke rendered as solid colors.

Description of Change

Three platform-level changes enable gradient stroke rendering on Android and iOS/macCatalyst:

src/Core/src/Graphics/ShapeDrawable.cs

• Added canvas.SetFillPaint(stroke, dirtyRect) call before canvas.DrawPath(path) in DrawStrokePath
• Updated the TODO comment to scope it to Windows only (since Android and iOS are now fixed)
• The existing canvas.StrokeColor = stroke.ToColor() is preserved as the Windows fallback (solid color)

src/Graphics/src/Graphics/Platforms/Android/PlatformCanvas.cs

• In PlatformDrawPath, applies _shader (set by SetFillPaint) to CurrentState.StrokePaintWithAlpha before drawing, enabling gradient-stroked paths on Android

src/Graphics/src/Graphics/Platforms/MaciOS/PlatformCanvas.cs

• In PlatformDrawPath, when _gradient is set (by SetFillPaint), uses the existing FillWithGradient() + CGContext.ReplacePathWithStrokedPath() pattern — the standard Core Graphics technique for clipping a gradient fill to the outline of a stroked path

Platforms Fixed

• ✅ Android
• ✅ iOS / macCatalyst
• ❌ Windows — still pending (TODO in ShapeDrawable.cs); falls back to solid color (first gradient stop)

🔴 Critical Issues

Android: Gradient shader not cleared after use — subsequent solid-color strokes will render with previous gradient

File: src/Graphics/src/Graphics/Platforms/Android/PlatformCanvas.cs

Problem:
StrokePaintWithAlpha returns the same _strokePaint object each time (it only updates the ARGB color via SetARGB). When PlatformDrawPath calls CurrentState.StrokePaintWithAlpha.SetShader(_shader), the shader persists on _strokePaint across subsequent draw calls. There is no path to clear it:

• SetFillPaintShader(null) (called by SetFillPaint when switching to a non-gradient paint) only clears FillPaint's shader — not StrokePaint's shader.
• When the next shape draws a solid-color stroke, _shader is null and the if (_shader != null) block is skipped — so StrokePaintWithAlpha's shader is never cleared.

In Android, a Paint with a Shader renders using the shader's colors (the solid color set via SetARGB is ignored). This means all subsequent solid-color stroke operations after any gradient stroke will still render using the previous gradient's colors.

Current code (buggy):

protected override void PlatformDrawPath(PathF aPath)
{
    var platformPath = aPath.AsAndroidPath();
    if (_shader != null)
    {
        CurrentState.StrokePaintWithAlpha.SetShader(_shader);
    }
    // ❌ If _shader is null, the old shader remains on StrokePaintWithAlpha
    _canvas.DrawPath(platformPath, CurrentState.StrokePaintWithAlpha);
    platformPath.Dispose();
}

Recommended fix:

protected override void PlatformDrawPath(PathF aPath)
{
    var platformPath = aPath.AsAndroidPath();
    // Always set (or clear) the shader — passing null explicitly removes it from the Paint
    CurrentState.StrokePaintWithAlpha.SetShader(_shader);
    _canvas.DrawPath(platformPath, CurrentState.StrokePaintWithAlpha);
    platformPath.Dispose();
}

This same pattern is missing for all other PlatformDraw* methods that use StrokePaintWithAlpha (e.g. DrawLine, DrawArc, DrawRectangle, DrawRoundedRectangle, DrawOval) — they also don't apply the gradient shader. However, Shape.Stroke only routes through PlatformDrawPath, so those other methods are lower risk for this specific PR.

🟡 Suggestions

1. Missing newline at end of Issue21983.cs

File: src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue21983.cs

The file ends without a trailing newline (\ No newline at end of file). This is a minor style issue that can cause noisy diffs in the future.

Fix: Add a newline after #endif.

---

2. PlatformAffected.All is misleading on the HostApp issue attribute

File: src/Controls/tests/TestCases.HostApp/Issues/Issue21983.xaml.cs

[Issue(IssueTracker.Github, 21983, "GradientBrushes are not supported on Shape.Stroke", PlatformAffected.All)]

Windows still has the bug (Shape.Stroke gradient is still a TODO in ShapeDrawable.cs), and the UI test itself is wrapped in #if !WINDOWS. Using PlatformAffected.All implies the fix covers all platforms, which is inaccurate.

Recommended: Change to PlatformAffected.iOS | PlatformAffected.Android (or the equivalent enum values for iOS/macCatalyst + Android) to accurately reflect what this PR fixes.

---

✅ Looks Good

• iOS/macCatalyst implementation is clean and correct. Using CGContext.ReplacePathWithStrokedPath() to convert the stroke outline to a clippable fill path, then rendering the gradient via FillWithGradient(), is the standard and well-established Core Graphics pattern. The FillWithGradient helper correctly handles the save/clip/draw/restore lifecycle.

• ShapeDrawable.cs approach is sound. Calling SetFillPaint(stroke, dirtyRect) before DrawPath correctly reuses the existing gradient infrastructure without duplicating gradient-setup logic. The TODO comment update accurately scopes the remaining Windows limitation.

• Test coverage is appropriate. A screenshot comparison test with two gradient brush types (Linear and Radial) on two shape types (Path and Ellipse) covers the key scenarios. The #if !WINDOWS guard is correct given the Windows limitation.

• Before/after screenshots in the PR description clearly demonstrate the fix visually.

Code Review — PR #22208

Summary

Adds gradient brush (LinearGradientBrush, RadialGradientBrush) support to Shape.Stroke on Android and iOS/macCatalyst. The approach reuses existing fill-gradient infrastructure:

• ShapeDrawable.cs: Calls canvas.SetFillPaint(stroke, dirtyRect) before DrawPath to set up gradient state.
• Android PlatformCanvas: Applies _shader to StrokePaintWithAlpha in PlatformDrawPath.
• iOS PlatformCanvas: Converts the stroke path to a filled outline via ReplacePathWithStrokedPath() and fills with the gradient via FillWithGradient.

The platform implementations are architecturally sound. Backward compatibility for solid color strokes is maintained (SetFillPaint(SolidPaint) sets _shader = null, so PlatformDrawPath skips the shader path).

Findings

❌ Wrong namespace in test file

Issue21983.cs (Shared.Tests) uses namespace Microsoft.Maui.AppiumTests.Issues — this namespace has 0 usages in the codebase. The correct namespace is Microsoft.Maui.TestCases.Tests.Issues (1,205 usages). This will prevent the test from being discovered by the test runner.

📍 src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue21983.cs:8

⚠️ Missing newline at end of test file

Issue21983.cs is missing a trailing newline.

📍 src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue21983.cs:26

💡 Add explanatory comment for SetFillPaint usage in stroke path

In ShapeDrawable.DrawStrokePath, canvas.SetFillPaint(stroke, dirtyRect) repurposes the fill-paint API to configure stroke gradients. A brief comment would help future maintainers understand the intent:

// Use SetFillPaint to configure gradient state (shader/CGGradient)
// which PlatformDrawPath will apply to the stroke rendering.
canvas.SetFillPaint(stroke, dirtyRect);

📍 src/Core/src/Graphics/ShapeDrawable.cs:110

💡 Consider clearing shader from StrokePaint after draw (Android)

On iOS, FillWithGradient disposes _gradient after use. On Android, the shader set on StrokePaintWithAlpha is never explicitly cleared. Analysis confirms this is safe (SaveState/RestoreState scoping prevents leaks), but adding CurrentState.StrokePaintWithAlpha.SetShader(null) after the draw would improve symmetry with iOS.

📍 src/Graphics/src/Graphics/Platforms/Android/PlatformCanvas.cs:550-554

---

Verdict: Needs Changes

The gradient stroke implementation is correct and the platform approaches (shader on Android, stroked-path-to-fill on iOS) are well-chosen. The namespace issue in the test file must be fixed — it will prevent the test from running. Other findings are suggestions.

Issue: #21983 - GradientBrushes are not supported on Shape.Stroke
PR: #22208 - Added a support for GradientBrushes on Shape.Stroke
Author: kubaflo
Platforms Affected: Android, iOS/macOS (Windows excluded — future work per TODO comment)
Files Changed: 3 implementation files, 3 test files, 3 snapshot baselines

Issue Summary

When applying a LinearGradientBrush or RadialGradientBrush to the Stroke property of a Shape (Path, Ellipse, etc.), only the first color of the gradient was applied (as if it were a SolidColorBrush). Fill and Background gradients worked correctly. Regression from Xamarin.Forms. Affects Android (confirmed at 17.10.0-preview4) and also observed on Windows.

Prior Agent Review

This PR was previously reviewed by the agent (labels: s/agent-reviewed, s/agent-changes-requested, s/agent-fix-win, s/agent-fix-implemented). The prior agent found an issue with Android shader state management and the author implemented the suggested fix. The current PR state reflects those improvements:

• Android implementation now uses GetFillPath + FillPaintWithAlpha (avoids shader bleed on StrokePaintWithAlpha)
• Namespace in test file is now correct: Microsoft.Maui.TestCases.Tests.Issues

Fix Approach (Current PR State)

The PR uses a layered gradient-to-stroke pipeline:

1. ShapeDrawable.cs (cross-platform): Calls canvas.SetFillPaint(stroke, path.Bounds) before canvas.DrawPath(path) to push gradient state (_shader/_gradient) into the platform canvas. Also keeps canvas.StrokeColor = stroke.ToColor() for solid-color fallback on Windows.
2. PlatformCanvas.cs (Android): In PlatformDrawPath, if _shader != null, converts stroke geometry to a filled outline via StrokePaintWithAlpha.GetFillPath(), then draws with FillPaintWithAlpha (which has the gradient shader from SetFillPaint). Falls back to original DrawPath with StrokePaintWithAlpha when no gradient.
3. PlatformCanvas.cs (MaciOS): In PlatformDrawPath, if _gradient != null, uses FillWithGradient(() => { ReplacePathWithStrokedPath(); }) to convert the stroke path to a filled outline and render with gradient. Falls back to normal DrawPath(CGPathDrawingMode.Stroke).

Key Findings

• Gate ✅ PASSED — tests FAIL without fix, PASS with fix
• The Android approach uses FillPaintWithAlpha (not StrokePaintWithAlpha), which cleanly avoids the shader bleed concern raised in the prior review
• StrokeColor + SetFillPaint both set state; on non-gradient stroke, _shader/_gradient remains null and the else branch uses the solid color correctly
• HostApp page tests Path with LinearGradientBrush stroke, Ellipse with RadialGradientBrush stroke, and Ellipse with RadialGradientBrush fill (for comparison)
• Windows implementation is intentionally deferred (TODO comment updated accordingly)
• Copilot inline review comments from prior pass are now addressed

Remaining Open Points

• Windows gradient stroke support not implemented (deferred)
• SetFillPaint is called even for solid color SolidColorBrush strokes (where _shader will be null); no functional regression but adds a no-op call

Fix Candidates

#	Source	Approach	Test Result	Files Changed	Notes
1	try-fix (claude-opus-4.6)	Direct shader on StrokePaint — skip GetFillPath, apply _shader directly to StrokePaintWithAlpha and draw stroke normally	✅ PASS	3 files	Simpler than PR: no geometry conversion, preserves dash/caps/joins naturally
2	try-fix (claude-sonnet-4.6)	Add dedicated SetStrokePaint(Paint, RectF) API to ICanvas — proper new method with separate _strokeShader field in Android PlatformCanvas; no changes to PlatformDrawPath	✅ PASS	8 files (ICanvas, AbstractCanvas, PlatformCanvas, PlatformCanvasState, ScalingCanvas, PictureCanvas, ShapeDrawable, 8× PublicAPI.Unshipped.txt)	Significant scope: public API change across multiple canvas types; needed 5 test iterations to align gradient bounds
3	try-fix (gpt-5.3-codex)	Android SaveLayer + SrcIn mask — draw stroke as opaque mask, then fill bounds with gradient using PorterDuff.Mode.SrcIn; no GetFillPath, no shader assignment, no new API	✅ PASS	2 files	Compositional approach; needed layer bounds refinement
4	try-fix (gpt-5.4, gemini unavailable)	Bitmap-backed clipped stroke fill — GetFillPath to outline, render gradient to offscreen bitmap for stroke bounds, clip to outline, draw bitmap back	✅ PASS	2 files	Most complex approach; offscreen bitmap allocation
PR	PR #22208	SetFillPaint + GetFillPath/FillPaintWithAlpha (Android) + ReplacePathWithStrokedPath/FillWithGradient (iOS)	✅ PASSED (Gate)	3 files	Original PR

Cross-Pollination

Model	Round	New Ideas?	Details
claude-opus-4.6	2	NO NEW IDEAS	"Five approaches exhaustively cover the design space"

Exhausted: Yes
Selected Fix: Attempt 1 (Direct shader on StrokePaint) — Passes all tests, simplest implementation (3 files, no intermediate Path allocation, no geometry conversion), and preserves all stroke attributes (dash, caps, joins) naturally. The PR's GetFillPath converts stroke geometry to fill outline which adds complexity and could subtly alter dash-pattern rendering. Direct SetShader + clear-after is idiomatic Android; the GPU handles gradient coloring natively along the stroke width.

Summary

PR #22208 adds GradientBrush support for Shape.Stroke on Android and iOS/macOS, fixing issue #21983. The fix is correct and the Gate passed. However, try-fix exploration identified a simpler Android implementation (Attempt 1) that avoids the GetFillPath geometry conversion used in the current PR — direct SetShader on StrokePaintWithAlpha is the idiomatic Android approach and preserves all stroke attributes (dash patterns, line caps, joins) without intermediate object allocation.

Root Cause

In ShapeDrawable.DrawStrokePath, canvas.StrokeColor = stroke.ToColor() resolves a GradientBrush to only its first color. The fix adds canvas.SetFillPaint(stroke, path.Bounds) to push full gradient state into the platform canvas, then each platform canvas detects and applies the gradient during PlatformDrawPath.

Fix Quality

The PR's approach is functionally correct and Gate-verified. The suggested alternative simplifies the Android path:

Current PR (Android PlatformDrawPath):

if (_shader != null)
{
    using var strokedOutline = new Path();
    CurrentState.StrokePaintWithAlpha.GetFillPath(platformPath, strokedOutline);
    _canvas.DrawPath(strokedOutline, CurrentState.FillPaintWithAlpha);
}

• Converts stroke geometry to a fill outline (CPU-side allocation + disposal)
• Draws the outline with FillPaintWithAlpha (shares fill paint state)

Simpler alternative (Attempt 1):

if (_shader != null)
{
    var strokePaint = CurrentState.StrokePaintWithAlpha;
    strokePaint.SetShader(_shader);
    _canvas.DrawPath(platformPath, strokePaint);
    strokePaint.SetShader(null);  // explicit clear prevents bleed
}

• No intermediate Path allocation
• Draws the original stroke path with shader applied — GPU handles gradient coloring
• Explicitly clears shader after draw (no bleed risk)
• Preserves stroke attributes (dashes, caps, joins) accurately; GetFillPath converts these into fill geometry which can subtly alter rendering for complex strokes

The iOS approach in both PR and Attempt 1 is functionally equivalent (ReplacePathWithStrokedPath + gradient fill). Attempt 1 uses a direct Clip/DrawGradient sequence instead of the FillWithGradient wrapper, which is slightly more explicit.

Suggested Change (Android only)

In src/Graphics/src/Graphics/Platforms/Android/PlatformCanvas.cs, replace the GetFillPath block with direct shader assignment:

-            if (_shader != null)
-            {
-                using var strokedOutline = new Path();
-                CurrentState.StrokePaintWithAlpha.GetFillPath(platformPath, strokedOutline);
-                _canvas.DrawPath(strokedOutline, CurrentState.FillPaintWithAlpha);
-            }
-            else
-            {
-                _canvas.DrawPath(platformPath, CurrentState.StrokePaintWithAlpha);
-            }
+            if (_shader != null)
+            {
+                var strokePaint = CurrentState.StrokePaintWithAlpha;
+                strokePaint.SetShader(_shader);
+                _canvas.DrawPath(platformPath, strokePaint);
+                strokePaint.SetShader(null);
+            }
+            else
+            {
+                _canvas.DrawPath(platformPath, CurrentState.StrokePaintWithAlpha);
+            }

This was validated as ✅ PASS by Attempt 1 (claude-opus-4.6).

Other Observations

• Windows gradient stroke is deferred (TODO comment updated) — acceptable for now
• canvas.StrokeColor = stroke.ToColor() is still called alongside SetFillPaint — for non-gradient strokes _shader is null and the solid color path is taken correctly
• Test (UITest screenshot + VerifyScreenshot(retryTimeout)) is well-structured and covers Path + Ellipse with both Linear and Radial gradient strokes
