Hello,
I was hoping if there’s a list of all the error messages that you can get when you do a PDF accessibility checker via Aspose. I needed it for documentation. If there’s no list can you please tell me any site that will have this information?
Thanks for contacting support.
I like to inform that there is no such list. However i have created investigation ticket with ID PDFNET-47507 in our tracking system to investigate if we can provide such list to you.
Thank you Adnan from your quick response. Yes, it would really help us if a list is provided
Sure, we have created ticket to investigate this. I request for your patience and we will share good news with you soon.
