**Which product are you using?**

**PDF.js Express Plus 8.7.4**

**Detailed description of issue**  
When user adds signature to the signature form widget (“Sign here” area), he can further move / resize the signature. Is there a way to forbid changing the signature position? Setting signature annotation as ReadOnly / Locked / LockedContents doesn’t help.

**Expected behaviour**  
Described above.

**Code snippet**  
signatureTool.addEventListener(‘annotationAdded’, (annotation) =\> {  
if (annotation.Subject === ‘Signature’) {  
annotation.ReadOnly = true;  
annotation.Locked = true;  
annotation.LockedContents = true;  
}  
});

Hello nikitakemarskiy,

Can you try this instead?

```javascript
annotationManager.addEventListener(‘annotationChanged’, (annotations, action, info) => {
if (annotations[0].Subject === ‘Signature’ && action === "add") {
annotation[0].ReadOnly = true;
annotation[0].Locked = true;
annotation[0].LockedContents = true;
}
});

```

Best regards  
Tyler

This approach works, thanks @tgordon!
