Using a tesseract with a c# wrapper

[NBL]

I am trying to get the libtesseract302 to work in a c# dll. The c# dll works with an earlier version of the tesseract called tessdll. I am currently unable to find entrypoints for the new dll in the documentation. For example where can I find the following entry points for the new version of the Tesseract dll

TessDllInit

TessDllRelease
TessDllRecognize_all_Words
TessDllRecognize_a_Block
TessDllEndPage
TessDllBeginPageUprightBPP
TessDllBeginPageLangBPP
TessDllBeginPageBPP
TessDllBeginPageUpright
TessDllBeginPageLang
TessDllBeginPage

Thanks for any help.

tessdll (wrapper for tesseract 2) is no compatible with tesseract 3. So there are no such entry points, any you need to use tesseract 3 functions.

I am afraid this homework you will need to do by yourself.

3.0x api is available in baseapi.h[1] and it is commented quite well.

See this Github project.  He's got precompiled Tesseract and Leptonica dependencies included in the project, along with a C# wrapper ready to go.  Plus a couple of sample apps to boot.
