[Bug]: Unity 2018, PNG files outline generate issue

[Soneoylys]

Are you on the latest version of AssetRipper?

Yes, I'm on the latest release of AssetRipper.

Which release are you using?

MacOS x64

Which Unity version did this occur on?

2018.4.7f1

Is the game Mono or IL2Cpp?

Mono

Describe the issue.

AssetRipper seems have some issue with generating outline

For example, check PNG files in this folder: ExportedProject/Assets/Resources/common/sprites/button/

Settings I'm using:

• [Import] Skip StreamingAssets Folder --> DISABLE
• [Experimental] Enable Prefab Outlining --> ENABLE
• [Export] Sprite Export Format --> Texture
• [Export] Shader Export Format --> Decompilation
• [Export] Script Export Format --> Decompilation
• [Export] C# Language Version --> C# 9

I did bumped the editor version to 2022 LTS, but I don't think that's the problem in this case
