Aravindb:
In first step u specify need to convert image file to pdf .but what that file u use ?
Input.pdf is converted form image file using Aspose tool ?
And what about test.jpg file ? test.jpg is image file and input.pdf is converted form test.jpg file ? Then why again need to use test.jpg file
Note: pls provide in vb language,specify which tesseract OCR need to download,here i attach one file and download what i specify by red redtangle box,if i open i didnt see any exe file.
Regards

Yes we have used Aspose.Pdf to convert image to PDF file (input.pdf), rest of the code is tesseract related code it needs the image files as argument for ocr. You may check tesseract specification for related query.
