Signature image is not visible in digitally signed documents with GroupDocs.Signature REST API

Hey Tilal,
Thanks for reaching out to me, i really appreciate it. I was able to resolve the issue by correcting the storage and paths. But there’s an underlying problem that I am facing right now. I am uploading both the Seal image and certificate to the storage. But i am unable to view the seal on the digitally signed document. Please guide as to how I can add a seal to the document using the node sdk so that it’s visible on the Digitally signed document.


While signing the document, please set the visible property of SignDigitalOptions to true as its default value is false. It will help you to show the signature image in the output document.

Hey Tilal thanks for the response. I was able to display seal successfully, But there’s an underlying issue. The seal image uploaded is distorted and placed on the top right corner of the page by default. Is there a way i can place the seal image dynamically according to my own choice. I have multiple different documents to be digitally signed, and each of them has different spots for placing the seal. Please help me in this regard.


Please use the Left and Top parameter to control the signature image position. Top left position is 0,0. For the distorted image issue, you may use the Width and Height parameter as per your requirement. Hopefully, it will resolve the issue.

Sign document with digital signature

Hey Tilal, Thanks for the timely response, but i guess i didn’t clearly communicate the issue here. I’ll be using group docs API for a client focused application. For the time being i can provide the left right or top positions in my code. But after product launch i cannot expect my clientele to provide left right or top position during the document signing as they are not much of techy people. Is there any other way to continue with this?


I am afraid currently there are no other options available at the moment. As per my understanding, it is more convenient for an API user(developer) to control the position with these parameters. You can get the desired coordinates in your application and map them with the page coordinates to insert the signature. Anyhow, if you have some other suggestions then please share them with us.
