96 DPI Resolution Image Processing

Aspose.OCR Product Family
1

Hi,
I’m trying to process OCR images, which are in 96 DPI resolution, can you please let me know how i can process those images.

As per ASPOSE documentation, image processing works fine for 300 DPI resolution, but most of our images are in 96 DPI.

Please let me know, how i can resolve this issue.

Thanks and Regards,
Suresh Kumar M
