Issue Details

Build fails with InvalidOperationException when using an empty (but valid) SVG as the app icon. The SVG has width, height, and viewBox but no drawn shapes inside.

Root Cause

PR #33194 moved the size.IsEmpty check to run before both code paths in DrawUnscaled, but size (from CullRect) is only needed in the downscale path. Empty SVGs have a zero CullRect even with valid declared dimensions, so the check incorrectly blocks the upscale path that never uses size.

Description of Change

Moved the size.IsEmpty check from before both branches into only the else (downscale) branch where size is actually used. The scale >= 1 path calls DrawPicture directly, which harmlessly draws nothing for empty SVGs, producing a valid transparent image.

• Android
• Windows

Pull request overview

This PR updates Resizetizer’s SVG rendering path so empty-but-valid SVG app icons can build successfully, and adds regression coverage plus a fixture for that scenario. The title/description match the implementation.

Changes:

• Moves the empty-SVG size check so it only runs in the downscale branch of SkiaSharpSvgTools.DrawUnscaled.
• Adds a unit test covering an empty SVG used as an app icon.
• Adds a new empty SVG test asset.

🤖 Automated review — alternative fix proposed

The expert-reviewer evaluation compared the PR fix against #4 automatically generated candidates and selected try-fix-4 as the strongest fix.

Why: try-fix-4 wins by centralizing empty-CullRect handling in a new ResolveOriginalSize() base method (SkiaSharpTools.cs), which eliminates the NaN/∞ float arithmetic bug, simplifies DrawUnscaled with a clean 'scale >= 1 || size.IsEmpty' pattern, requires no XML parsing overhead, and includes comprehensive tests. The PR fix failed Gate and silently drops PR #33194's MAUIR0001 protection for malformed SVGs at scale >= 1, which all 4 try-fix candidates address.

Candidate diff (try-fix-4)

The fix is invalid because when the SVG has no content, the scale becomes NaN (due to divide-by-zero), and NaN >= 1 is always false — so the code never reaches the safe path and still throws the same error

🤖 Automated review — alternative fix proposed

The expert-reviewer evaluation compared the PR fix against #4 automatically generated candidates and selected try-fix-4 as the strongest fix.

Why: try-fix-4 wins by fixing the root cause in GetOriginalSize() rather than working around it in DrawUnscaled. By parsing declared SVG width/height/viewBox attributes at construction time, it returns the true declared dimensions (e.g., 456×456) for empty-but-valid SVGs, eliminating NaN/Infinity in GetScaledSize and fully restoring MAUIR0001 protection for both scale branches. The PR's own fix (moving the guard to the else-branch only) correctly handles the reported app-icon scenario but silently drops the diagnostic for truly malformed SVGs at scale >= 1 and leaves downstream arithmetic bugs for non-app-icon callers.

Please consider applying the candidate diff below (or use it as guidance). Once you push an update, this workflow will re-trigger and re-evaluate.

Issue: #35293 - Build fails when appicon is an empty (but valid) SVG after upgrade to 10.0.60
PR: #35305 - Fix: Build fails when appicon is an empty (but valid) SVG
Platforms Affected: Android, iOS, macOS, Windows (all platforms that use Resizetizer for app icon generation)
Files Changed: 1 implementation, 2 test (1 test class file + 1 new SVG asset)

Key Findings

• Regression introduced by PR Fix: Throw a clear error when an SVG lacks dimensions instead of a NullReferenceException #33194 which added a size.IsEmpty guard before both code paths in DrawUnscaled. The guard was appropriate only for the downscale (else) branch.
• Empty SVGs (valid declared dimensions but no rendered content) have CullRect.Size = (0,0) in SkiaSharp, causing the guard to incorrectly reject them.
• PR fix moves the size.IsEmpty check into the else branch only, where it is actually needed (SKImageInfo requires non-zero dimensions).
• The scale >= 1 path (canvas.DrawPicture) works correctly with empty SVGs, producing a valid transparent image.
• Gate ❌ FAILED: The new test EmptySvgAppIconSucceeds_Issue35293 uses an SVG with viewBox="0 0 456 456". Svg.Skia sets the Picture's CullRect from the viewBox, so CullRect.Size = (456, 456) (non-empty). As a result, the test passes even on the broken baseline (pre-fix state), making it an ineffective regression test.
• The reviewer (copilot-pull-request-reviewer) raised that removing the check from the scale >= 1 path silently drops MAUIR0001 protection for truly malformed SVGs (no width/height/viewBox). The author counter-argued that DrawPicture handles empty SVGs harmlessly.
• The reviewer's concern is partially valid: for truly malformed SVGs (no declared dimensions), GetScaledSize computes scale = Infinity (due to 0/0 division), so scale >= 1 is always true, and MAUIR0001 is now unreachable for those SVGs too. This is a silent regression of the protective error added in PR Fix: Throw a clear error when an SVG lacks dimensions instead of a NullReferenceException #33194.

Code Review Summary

Verdict: NEEDS_CHANGES
Confidence: high
Errors: 2 | Warnings: 1 | Suggestions: 1

Key code review findings:

• ❌ src/SingleProject/Resizetizer/src/SkiaSharpSvgTools.cs:45-48 — MAUIR0001 error in the else branch is dead code for truly malformed SVGs. When an SVG has no declared dimensions (the case PR Fix: Throw a clear error when an SVG lacks dimensions instead of a NullReferenceException #33194 intended to protect), GetScaledSize computes scale = Infinity, so the else branch is never entered. The MAUIR0001 protection is effectively removed for malformed SVGs.
• ❌ src/SingleProject/Resizetizer/test/UnitTests/images/appicon_empty.svg — Test SVG has viewBox="0 0 456 456", making CullRect.Size = (456, 456). The test EmptySvgAppIconSucceeds_Issue35293 passes even on the broken baseline, so the Gate failed — the test does not verify the regression.
• ⚠️ src/SingleProject/Resizetizer/src/SkiaSharpSvgTools.cs:38-65 — The fix does not address the NaN/Infinity arithmetic hazard in GetScaledSize when originalSize = (0,0) and no BaseSize or explicit dpi.Size is provided. For non-app-icon SVG images rendered directly, this could cause silent NaN in canvas transform scaling.
• 💡 Consider differentiating "empty content" (CullRect empty, declared dimensions valid) from "malformed" (no declared dimensions) for a more precise guard, so MAUIR0001 still fires for truly malformed SVGs.

Code Review — PR #35305

Independent Assessment

What this changes: The size.IsEmpty guard in SkiaSharpSvgTools.DrawUnscaled is relocated from the top of the method (before the scale >= 1 / scale < 1 branch) to inside the else (downscale, scale < 1) branch only. A new test and test SVG asset are added.

Inferred motivation: An SVG with valid viewport declarations (width, height, viewBox) but no drawn content will have an empty CullRect as reported by SkiaSharp's Svg.Skia library. The previous guard — added by PR #33194 — checked size.IsEmpty before reaching either code path, which meant a valid-but-empty SVG used as an app icon would always throw InvalidOperationException, even though the scale >= 1 path (canvas.DrawPicture) can handle an empty picture gracefully (it simply draws nothing). The downscale path is the one that actually requires non-zero dimensions, because it creates SKSurface from the raw pixel dimensions.

Is the approach sound? Yes. The behavioral split is well-founded:

• DrawPicture(svg.Picture, Paint) — SkiaSharp handles an empty SKPicture safely; the result is a transparent bitmap.
• SKSurface.Create(new SKImageInfo(0, 0)) — would return null in SkiaSharp, causing a NullReferenceException on the subsequent .Canvas access. The guard must stay here.

Moving the check into the else branch is the minimal, correct fix.

---

Reconciliation with PR Narrative

Author claims: The size.IsEmpty check was incorrectly placed to execute before both branches; only the downscale branch actually uses size to construct an SKImageInfo. Empty SVGs (valid dimensions, no content) produce a zero CullRect even though DrawPicture can handle them harmlessly.

Agreement: My independent reading matches exactly. The author's root-cause analysis is correct.

Prior review thread (already resolved): A previous copilot reviewer raised the concern that moving the check removes error protection for the scale >= 1 path. The author's rebuttal — "DrawPicture harmlessly draws nothing for empty SVGs" — is correct. The concern was about truly dimensionless SVGs (PR #32460), but (a) those also produce a blank asset on the DrawPicture path (no crash), and (b) the constructor already emits a warning log for zero-CullRect SVGs. The tradeoff is acceptable.

Findings

💡 Suggestion — Test does not assert output files are generated

File: src/SingleProject/Resizetizer/test/UnitTests/ResizetizeImagesTests.cs:120–136

EmptySvgAppIconSucceeds_Issue35293 checks only that task.Execute() returns true. For comparison, the analogous BasicImageProcessingWorks test calls AssertFileExists(GetPlatformOutputFileName(...)) after checking success. Without asserting that output PNG files were produced, a regression where the task "succeeds" but silently skips file generation would not be caught.

// Consider adding after Assert.True(success, ...):
AssertFileExists(GetPlatformOutputFileName("appicon.png")); // adjust to actual expected output

Not a blocker — the primary regression (crash / InvalidOperationException) is covered — but verifying file existence would make the test more robust.

💡 Suggestion — Stale constructor warning message

File: src/SingleProject/Resizetizer/src/SkiaSharpSvgTools.cs:29–30

The constructor logs: "SVG picture did not have a size and will fail to generate." After this fix, a zero-CullRect SVG at scale >= 1 does produce output (a transparent image). The message is now misleading for that code path. Consider updating to "SVG picture has an empty bounding box; output will be transparent." or similar.

---

Devil's Advocate

"Is the scale check reliable?" Yes — scale is a computed ratio in SkiaSharpTools.Draw. For standard app-icon DPI paths (1×, 1.5×, 2×, 3×), scale is always ≥ 1 when the target canvas is the same size or larger than the nominal image. The only time scale < 1 is triggered is when the canvas is smaller than the source image's nominal size — a narrower scenario. The guard in the else branch will fire correctly when needed.

"Could canvas.Scale(+∞, +∞) crash in the app-icon path?" When GetOriginalSize() returns 0×0 and the platform DPI path has a fixed dpi.Size, GetScaledSize produces +Infinity scale due to IEEE 754 division of a positive number by 0.0. canvas.Scale(+Infinity, +Infinity) with a subsequent DrawPicture on an empty picture is a no-op in Skia — no pixel writes occur. The bitmap is saved as a transparent PNG. This has always been the behavior before PR #33194; the current PR restores it for the scale >= 1 path.

"Should the error path be re-added for truly dimensionless SVGs at scale ≥ 1?" A more complete fix would distinguish between "empty content but valid viewport" (should succeed) and "no dimensions at all" (should error). However, implementing that distinction requires reading SVG attributes separately from CullRect, which is more invasive and out of scope for this focused regression fix. The existing constructor warning provides the signal for the "no dimensions" case.

---

CI Status

All completed checks are green (Build Windows/macOS Debug/Release, Pack, Helix Unit Tests, Integration Tests across all platforms and templates). Some checks show as pending which is consistent with a PR that has already merged — those jobs are simply no longer running against this branch. ✅

---

Verdict: LGTM

Confidence: high

Summary: The fix is logically sound. DrawPicture safely handles an empty SKPicture (produces transparent output), while SKSurface.Create(0, 0) does not — so confining the size.IsEmpty check to the downscale branch is the correct, minimal fix. The regression test covers the reported scenario. The two suggestions above are minor improvements that do not block merge. All CI checks pass.

Fix Candidates

#	Source	Approach	Test Result	Files Changed	Notes
1	try-fix-1 (claude-opus-4.6)	Combine scale>=1 || size.IsEmpty as single condition; remove exception; fix test SVG to viewBox="0 0 0 0"	✅ PASS	SkiaSharpSvgTools.cs, appicon_empty.svg	No exception for any empty SVG; loses MAUIR0001
2	try-fix-2 (claude-sonnet-4.6)	Compound guard if (size.IsEmpty && scale < 1) throw at top of method; fix test SVG	✅ PASS	SkiaSharpSvgTools.cs, appicon_empty.svg	Preserves some error path; note scale=NaN (malformed SVG) → NaN<1=false so error unreachable
3	try-fix-3 (gpt-5.3-codex)	Parse SVG XML for declared dimensions; add hasDeclaredSize field; throw only when size.IsEmpty && !hasDeclaredSize	❌ FAIL	SkiaSharpSvgTools.cs, appicon_empty.svg	Native library load error in environment; approach is architecturally most complete
4	try-fix-4 (claude-sonnet-4.6)	Fix ONLY the test SVG (dimensionless <svg xmlns>) + update stale warning message; PR code fix unchanged	✅ PASS	SkiaSharpSvgTools.cs (warning msg only), appicon_empty.svg	Minimal — validates the PR code is correct; only test was broken
PR	PR #35305	Move size.IsEmpty check into else (downscale) branch only	⚠️ Gate ❌ FAILED	SkiaSharpSvgTools.cs, ResizetizeImagesTests.cs, appicon_empty.svg	Code logic is correct; test SVG has non-empty CullRect, so gate test passes vacuously

Cross-Pollination

After all 4 attempts:

Key finding: Attempt 4 confirmed that the PR's code fix is architecturally correct. The gate failed due to an ineffective test SVG, not a code error.

The three passing approaches are:

1. scale >= 1 || size.IsEmpty (Attempt 1) — eliminates error entirely; simplest but drops MAUIR0001
2. size.IsEmpty && scale < 1 guard at top (Attempt 2) — preserves throw path for scale<1 but unreachable for malformed SVGs in practice
3. Test-only fix + warning message update (Attempt 4) — validates PR code is correct; minimal invasive change

Model	Round	New Ideas?	Details
claude-opus-4.6	2	NO NEW IDEAS	Attempts 1 and 4 already cover the test-fix and code-simplification space
claude-sonnet-4.6	2	NO NEW IDEAS	Attempt 2 and 4 cover the compound-condition and test-only approaches
gpt-5.3-codex	2	NO NEW IDEAS	Attempt 3's metadata approach was the most sophisticated; env failure, not conceptual failure

Exhausted: Yes
Selected Fix: try-fix-4 — PR code fix is correct; only the test SVG needs to be a truly dimensionless SVG to catch the regression. Most targeted, minimal change.

Code Review Impact on Try-Fix

The code review found 2 minor suggestions (💡) only — no errors or warnings. These findings directly guided try-fix exploration: Attempt 4 specifically addressed the inaccurate warning message and invalid test SVG, both of which were flagged in the code review. The expert reviewer's LGTM verdict helped all try-fix models confirm that the code logic is sound and exploration should focus on the test quality, not the implementation.

Summary

PR #35305's code fix (moving size.IsEmpty into the else/downscale branch) is architecturally correct and minimal. However, the gate failed because the regression test uses an SVG with viewBox="0 0 456 456" — Svg.Skia sets CullRect from the viewBox, so size.IsEmpty is false even on the broken baseline, meaning the test passes vacuously without the fix. The winning candidate (pr-plus-reviewer) adds a dimensionless test SVG and updates the stale constructor warning message.

Root Cause

PR #33194 moved the size.IsEmpty guard to execute before both code paths in DrawUnscaled. Empty SVGs (valid declared dimensions, no drawn content) have an empty CullRect from Svg.Skia even though DrawPicture handles them safely. The guard only needs to protect the downscale path, where SKImageInfo(0, 0) would create a null surface.

Fix Quality

The PR's code logic is correct (LGTM from independent expert review). The test quality is insufficient: the test SVG appicon_empty.svg has viewBox="0 0 456 456" which provides non-zero CullRect dimensions, making the regression test ineffective. The pr-plus-reviewer candidate fixes this by using a dimensionless SVG (no width/height/viewBox) that genuinely triggers an empty CullRect and causes the test to fail on the broken baseline.

Selected Winner: pr-plus-reviewer

• PR code fix: ✅ correct (unchanged)
• Test SVG: fixed to <svg version="1.1" xmlns="http://www.w3.org/2000/svg"> (truly empty CullRect)
• Warning message: updated from "will fail to generate" to "may render at reduced quality when downscaled"

See inline comments for details.

[MauiBot]

[minor] Regression Prevention — EmptySvgAppIconSucceeds_Issue35293 checks only that task.Execute() returns true, but does not verify that output PNG files were actually produced. The comparable BasicImageProcessingWorks test calls AssertFileExists(GetPlatformOutputFileName(...)) after the success assertion. Without a file-existence check a future regression where the task silently skips output generation would pass this test. Consider adding AssertFileExists for the expected platform-specific output file (e.g., the app icon PNGs) to make the test a full regression guard.
