Getting Window Handles

To use this addon, you need to obtain window handles (HWND). You can:

1. Use other native modules that provide window enumeration
2. Use the Windows API from other languages
3. Use tools like FindWindow or EnumWindows from the Windows API

Notes

• tintColor and borderColor are optional: If not provided, no color will be applied
• Border is always visible: The addon doesn't provide functionality to hide borders
• Windows 11+ for border colors: Border color setting only works on Windows 11 and later
• Windows 10+ required: Acrylic effects require Windows 10 or later

Error Handling

The addon throws JavaScript errors for:

• Invalid parameters
• Invalid window handles
• Unsupported operations
• System API failures
