Signature with fixed position

Technical Support
1

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?

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
