What's NOT tested (but acceptable):
Verdict: Test coverage is sufficient for this fix. The test validates the reported issue is resolved. Additional edge case testing could be done in future PRs but is not required for approval. Memory Safety AnalysisSafe Image Sizes (with SIZE_ORIGINAL)
Edge Case: Ultra-Large ImagesScenario: User loads a 20000×4000 pixel panorama Risk: Could exceed Canvas limit (~100-300MB depending on device) Likelihood:

Pull request overview
This PR fixes a critical Android crash that occurs when loading images with width exceeding height. The fix introduces a constrainSize parameter to Glide image loading operations, forcing images to decode at original dimensions rather than scaled dimensions, which reduces memory usage and prevents crashes.
Key Changes:
- Added
constrainSizeparameter to Glide RequestBuilder configuration - Applied
override(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL)to constrain bitmap memory allocation - Enabled constraint for all file, URI, and stream-based image loads
- Added comprehensive UI test with wide aspect ratio test image

The WriteAsync method with three parameters (buffer, offset, count) is deprecated in modern .NET. Use the overload that accepts ReadOnlyMemory<byte> instead for better performance and to follow current best practices.

Inconsistent indentation throughout the file. Some lines use spaces (lines 8, 12, 14-17, 21) while others use tabs. This should be corrected to maintain consistent code formatting according to the project standards.

The field TestImage should follow C# naming conventions for private fields by using camelCase with an underscore prefix (e.g., _testImage) or simply be declared as a local variable in the constructor since it's only used during initialization.

Using async void for event handlers is generally acceptable, but this method is not an event handler. It's a fire-and-forget async call from the constructor. This pattern can make it difficult to handle exceptions and can lead to unobserved task exceptions.
Consider either:
- Making this a
Taskmethod and awaiting it properly in the constructor (though constructors can't be async) - Adding proper exception handling within the method
- Using a safer pattern like calling this from OnAppearing if it's a critical initialization step

The file created in local storage (test_wide_image.png) is never cleaned up. This could lead to accumulation of test files over time. Consider either cleaning up the file after the test completes or using a more deterministic file name that gets overwritten on subsequent runs.

✅ Approved
Validation Summary
- Fix validated on Android: Wide image (1600x130) loads successfully without the "Canvas: trying to draw too large bitmap" crash
- Build verified: Both HostApp and Shared.Tests compile successfully with the formatting fixes
Code Review Summary
The Glide fix using Target.SIZE_ORIGINAL is the correct approach - it prevents upscaling that causes the canvas overflow. The fix is consistently applied across all 6 relevant image loading methods.
Changes Made
I pushed a commit to fix minor formatting issues:
- Consistent tab indentation (was mixed tabs/spaces)
- Added trailing newlines at EOF
- Removed unused
using System.ComponentModel;
LGTM! 🚀

…eight (#33045) ### Issue Details: The user reads a local image, converts it into a byte array, creates a temporary file from it, and assigns the file’s path to the Image control’s Source property, but an exception occurs during this process. ### Root Cause: PlatformInterop.LoadImageFromFile(imageView, file, callback) fails to load the temporary file, which causes an exception to be thrown. ### Description of Change: The fix introduces a constrainSize parameter that, when enabled, applies override to the Glide RequestBuilder, forcing image decoding at original dimensions rather than scaled dimensions. This constraint reduces memory usage from hundreds of megabytes to manageable levels while preserving visual quality through ImageView's built-in scaling capabilities. The fix is automatically applied to all image loading methods including and ensuring consistent behavior across different image sources without breaking existing functionality or requiring API changes. **Tested the behavior in the following platforms.** - [x] Android - [x] Windows - [x] iOS - [x] Mac ### Reference: N/A ### Issues Fixed: Fixes #32869 ### Screenshots | Before | After | |---------|--------| | It throws expection when load image | <img width="380" height="1000" alt="image (6)" src="https://github.com/user-attachments/assets/73cc6fe7-dbec-4fa7-b593-83bdb6aadaf1" /> | --------- Co-authored-by: Stephane Delcroix <stephane@delcroix.org>

…eight (#33045) ### Issue Details: The user reads a local image, converts it into a byte array, creates a temporary file from it, and assigns the file’s path to the Image control’s Source property, but an exception occurs during this process. ### Root Cause: PlatformInterop.LoadImageFromFile(imageView, file, callback) fails to load the temporary file, which causes an exception to be thrown. ### Description of Change: The fix introduces a constrainSize parameter that, when enabled, applies override to the Glide RequestBuilder, forcing image decoding at original dimensions rather than scaled dimensions. This constraint reduces memory usage from hundreds of megabytes to manageable levels while preserving visual quality through ImageView's built-in scaling capabilities. The fix is automatically applied to all image loading methods including and ensuring consistent behavior across different image sources without breaking existing functionality or requiring API changes. **Tested the behavior in the following platforms.** - [x] Android - [x] Windows - [x] iOS - [x] Mac ### Reference: N/A ### Issues Fixed: Fixes #32869 ### Screenshots | Before | After | |---------|--------| | It throws expection when load image | <img width="380" height="1000" alt="image (6)" src="https://github.com/user-attachments/assets/73cc6fe7-dbec-4fa7-b593-83bdb6aadaf1" /> | --------- Co-authored-by: Stephane Delcroix <stephane@delcroix.org>

…eight (dotnet#33045) ### Issue Details: The user reads a local image, converts it into a byte array, creates a temporary file from it, and assigns the file’s path to the Image control’s Source property, but an exception occurs during this process. ### Root Cause: PlatformInterop.LoadImageFromFile(imageView, file, callback) fails to load the temporary file, which causes an exception to be thrown. ### Description of Change: The fix introduces a constrainSize parameter that, when enabled, applies override to the Glide RequestBuilder, forcing image decoding at original dimensions rather than scaled dimensions. This constraint reduces memory usage from hundreds of megabytes to manageable levels while preserving visual quality through ImageView's built-in scaling capabilities. The fix is automatically applied to all image loading methods including and ensuring consistent behavior across different image sources without breaking existing functionality or requiring API changes. **Tested the behavior in the following platforms.** - [x] Android - [x] Windows - [x] iOS - [x] Mac ### Reference: N/A ### Issues Fixed: Fixes dotnet#32869 ### Screenshots | Before | After | |---------|--------| | It throws expection when load image | <img width="380" height="1000" alt="image (6)" src="https://github.com/user-attachments/assets/73cc6fe7-dbec-4fa7-b593-83bdb6aadaf1" /> | --------- Co-authored-by: Stephane Delcroix <stephane@delcroix.org>

Thank you! Reverts the changes from dotnet#33045 which introduced a `constrainSize` parameter to Glide image loading methods. ## Changes ### PlatformInterop.java - Removed `constrainSize` parameter overloads from `prepare()`, `loadInto()`, and `load()` methods - Removed `.override(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL)` constraint logic - Reverted all image loading methods (`loadImageFromFile`, `loadImageFromUri`, `loadImageFromStream`) to original signatures ### Deleted Test Files - `TestCases.HostApp/Issues/Issue32869.cs` - `TestCases.Shared.Tests/Tests/Issues/Issue32869.cs` - `TestCases.HostApp/Resources/Raw/Issue32869.png` - Android/iOS snapshot files for Issue32869 > [!WARNING] > > <details> > <summary>Firewall rules blocked me from connecting to one or more addresses (expand for details)</summary> > > #### I tried to connect to the following addresses, but was blocked by firewall rules: > > - `plugins.gradle.org` > - Triggering command: `/usr/lib/jvm/temurin-17-jdk-amd64/bin/java /usr/lib/jvm/temurin-17-jdk-amd64/bin/java --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.invoke=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.prefs/java.util.prefs=ALL-UNNAMED --add-exports=jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED --add-exports=jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.prefs/java.util.prefs=ALL-UNNAMED --add-opens=java.base/java.nio.charset=ALL-UNNAMED --add-opens=java.base/java.net=ALL-UNNAMED --add-opens=java.base/java.util.concurrent.atomic=ALL-UNNAMED --add-opens=java.xml/javax.xml.namespace=ALL-UNNAMED -Xmx2048m -Dfile.encoding=UTF-8 -Duser.country -Duser.language=en -Duser.variant -cp /home/REDACTED/.gradle/wrapper/dists/gradle-8.13-all/54h0s9kvb6g2sinako7ub77ku/gradle-8.13/lib/gradle-daemon-main-8.13.jar` (dns block) > > If you need me to access, download, or install something from one of these locations, you can either: > > - Configure [Actions setup steps](https://gh.io/copilot/actions-setup-steps) to set up my environment, which run before the firewall is enabled > - Add the appropriate URLs or hosts to the custom allowlist in this repository's [Copilot coding agent settings](https://github.com/dotnet/maui/settings/copilot/coding_agent) (admins only) > > </details> <!-- START COPILOT CODING AGENT SUFFIX --> <!-- START COPILOT ORIGINAL PROMPT --> <details> <summary>Original prompt</summary> > Can you revert this PR dotnet#33045 </details> <!-- START COPILOT CODING AGENT TIPS --> --- ✨ Let Copilot coding agent [set things up for you](https://github.com/dotnet/maui/issues/new?title=✨+Set+up+Copilot+instructions&body=Configure%20instructions%20for%20this%20repository%20as%20documented%20in%20%5BBest%20practices%20for%20Copilot%20coding%20agent%20in%20your%20repository%5D%28https://gh.io/copilot-coding-agent-tips%29%2E%0A%0A%3COnboard%20this%20repo%3E&assignees=copilot) — coding agent works faster and does higher quality work when set up for your repo. --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: PureWeen <5375137+PureWeen@users.noreply.github.com>

Issue Details:
The user reads a local image, converts it into a byte array, creates a temporary file from it, and assigns the file’s path to the Image control’s Source property, but an exception occurs during this process.
Root Cause:
PlatformInterop.LoadImageFromFile(imageView, file, callback) fails to load the temporary file, which causes an exception to be thrown.
Description of Change:
The fix introduces a constrainSize parameter that, when enabled, applies override to the Glide RequestBuilder, forcing image decoding at original dimensions rather than scaled dimensions. This constraint reduces memory usage from hundreds of megabytes to manageable levels while preserving visual quality through ImageView's built-in scaling capabilities. The fix is automatically applied to all image loading methods including and ensuring consistent behavior across different image sources without breaking existing functionality or requiring API changes.
Tested the behavior in the following platforms.
