Hi CS,
At present, we do not have support to add image (logo) in QRBarcode using our PDF library. We have already logged a feature request for this and we do not have any immediate plan to implement this feature. We will implement this feature in any of our upcoming releases. We usually have an interval of at least three months between releases, at the planning stage of every release cycle, will review all the open features and we will notify you once this support is included.
You can track the status of the implementation in the below feedback,
Please let us know if you have any concerns on this.
Regards,
Gowthamraj K
