Aspose.OCR Product Family

Hi, Support,

I try to use aspose.OCr.dll version 17.11.0 to OCR Chinese text from image on VB.net, My Codes as follow:

Dim MyOCR As Global.Aspose.OCR.OcrEngine = New Global.Aspose.OCR.OcrEngine
MyOCR.Image = ImageStream.FromFile(PicFile)
Dim OCRL As Global.Aspose.OCR.ILanguage

OCRL.AddWord(“Chinese”) 'This will throw exception!

MyOCR.LanguageContainer.AddLanguages(OCRL) 'This will throw exception!

For the dll, there is no class method to load/add OCR language like :
MyOCR.Language…AddLanguages(Language.Load(“Chinese”))

Please Help me!

Thanks!

Thanks for contacting support.

Would you kindly use the latest version of the API by following examples given in the updated API documentation. In case you still face any issue, please feel free to let us know. In the latest version, there is no difference in performing OCR operation on images containing text in languages other than English

Thanks for your response.
But I’d like you to show me how let it work based on version 17.11 first.

Thanks for your suggestion.
But, It’s very very hard to download the latest version, I try several days to download it, all failed!
Would you send me a copy or the latest version dll or the Chinese language packs for version 17.11 so that I can use the following code to let it work!
Dim MyOCR As Global.Aspose.OCR.OcrEngine = New Global.Aspose.OCR.OcrEngine
Dim LanguageCh As Global.Aspose.OCR.ILanguage = LanguageFactory.Load(“Chinese”)
Dim LanguageEn As Global.Aspose.OCR.ILanguage = LanguageFactory.Load(“English”)
MyOCR.LanguageContainer.AddLanguage(LanguageCh )
MyOCR.LanguageContainer.AddLanguage(LanguageEn )

Regretfully, the Chinese language support was not available in 17.11 or any older version of the API.

Would you please explain what difficulties are you facing while downloading the latest version? Also, could you please share the image file that you want to process using the API. We will test the scenario in our environment and address it accordingly.
