I've reformatted the given code to follow standard C# conventions, proper indentation, and spacing. The existing logic and functionality remain unchanged.

public override ImageMask Inflate(int size)
{
}
Since there's no actual code within the method, I have left it empty to preserve its current state. If there were any content in the implementation, it would be properly indented and spaced according to C# conventions.
