Hi Krishnaram,


Thank you for writing back.

We have evaluated your presented scenario against the latest version of Aspose.OCR for Java 2.0.0 and your provided sample to receive the similar results. There are two most probable reasons for such results so you must take account of the following.

  • Aspose.OCR APIs works well with images having better resolution, where recommended resolution is 300 DPI.
  • The current implementation of the Aspose.OCR APIs support limited set of font families such as Arial, Times New Roman, Courier New, Tahoma, Calibri and Verdana.

In order to work the same sample, we would request you to please first try by saving the same image in higher resolution.
