Hello,

As per the document about "How to OCR Hindi text using VietOCR", I followed all the steps like :

1. Added hin.traineddata file in C:\Program Files\VietOCR.NET\tessdata folder.

2. added hi_IN.dic file in C:\Program Files\VietOCR.NET\dict folder

After that, I see the Hindi language option in language drop down. but when I tried to convert a document in hindi but its throwing this exception.

{"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."}

An unhandled exception of type 'System.AccessViolationException' occurred in InteropRuntimeImplementer.TessApiSignaturesInstance

Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Please help and suggest!

That document is for an old version of tesseract.

Please use vietocr version which supports tesseract 4.00alpha.

Download traineddata files for 4.00alpha from tessdata_fast

You can try OCR with both hin and Devanagari traineddata files.
