Thanks for your prompt reply.

I was trying to generate template as per my need, but using prepared template, I am not able to generate template(.omr). I am evaluating your aspose OMR product and willing to purchase if you can generate exact same template from your end. I have attached here. AnswerSheet Template.jpg (88.9 KB)

Also my credit limit for free trial reached to 51, can you please increase so that I also try to generate template as per my need.

We will surely let you know as soon as we have some definite updates regarding feature availability.
