We are sorry for the inconvenience. We will appreciate it if you please share a simple executable code along with your sourced PDF document and image. We will try to replicate the issue at our end and will provide you information accordingly.
Thanks for your feedback. I am afraid we have not tested the Aspose.Pdf on docker platform. However we have logged a ticket PDFNEWJAVA-34926 in our issue tracking system for further investigation. We will keep you updated about the issue resolution progress.
The issue reported earlier is pending for review as the team has been busy fixing other previously reported high priority issues. Nevertheless, I have intimated the team to try accommodating the issue in their development schedule and as soon as we have some further updates, we will let you know.
