We already edit PDF programmatically using Aspose.PDF. But we have customers that want to be able to annotate PDFs in a GUI. Is there anything in the Aspose family that would facilitate this, and if not, is there a recommended product/approach to use?
Thanks for your inquiry. For your requirements, you may try our another venture GroupDocs product. Please check following link to annotate PDFs in GUI. Hopefully it will help you to accomplish the task.
Please feel free to post your query over GroupDocs Annotation forum for further information.
