Hi All,

          I am new for Agisoft currently i am using python script for customisation, i need help from the experts for my below issue.
I am having multiple Ortho images and i need to generate the seamline now seamline function is working fine but the problem is  the images overlapping 80% each other so the generated seamline is coming wrong i want to generate the seamline for only 20% overlapping so i want to know how to modify/Adjust the image size for making 20% overlapping from 80% overlapping  using python.

Sorry for my english.

Thanks & Regards,
