|Nicomsoft OCR: Developer's Guide|
The files for redistribution are installed by the NSOCR SDK installer into the "Bin", "Bin_64" and "Bin_common" subfolders of the NSOCR installation folder.
Depending on your application and the target Windows version, two or three directories are necessary for your application:
|Application type / Platform||Windows x86||Windows x64|
|Native application (C/C++, Delphi, C++ Builder, etc.) x86||"Bin", "Bin_common"||"Bin", "Bin_common"|
|Native application (C/C++, Delphi, C++ Builder, etc.) x64||-||"Bin_64", "Bin_common"|
|.NET application with the "AnyCPU" target platform||"Bin", "Bin_common"||"Bin_64", "Bin_common"|
|.NET application with the "x86" target platform||"Bin", "Bin_common"||"Bin", "Bin_common"|
|.NET application with the "x64" target platform||-||"Bin_64", "Bin_common"|
It is possible to get rid of "Bin_common" folder: just copy all its files to both "Bin" and "Bin_64" folders.
You can also exclude some files to reduce the total size of the NSOCR runtime files that need to be distributed with your application:
|File name||Purpose||Can be excluded?|
|NSOCR.dll||OCR main module||NO|
|NsImgLdr.dll||Image loading and processing module||NO|
|ALL_base.dat||Character templates (for all languages)||NO|
|sd.dat||OCR helper data file||NO|
|DE.lng, ES.lng, FR.lng, etc.||Language dictionaries||YES|
|rgb.icc, gray.icc||ICC profiles for saving documents as PDF/A||YES|
|ICRDGT_base.dat||Character templates for handwritten digits (BT_ICRDIGIT)||YES|
|pdf_font.ttf||TrueType font for non-English languages support in output PDF files||YES|
|NsBars.dll||Barcodes recognition module||YES|
|TWAINDSM.dll||TWAIN scanning module||YES|
|"ASIAN" folder||Asian module and data files for Chinese, Arabic, Korean and Japanese languages||YES|
NSOCR’s main module is "NSOCR.DLL". It exposes OCR functions both via DLL and via COM.
If your application directly uses NSOCR functions from DLL, it must know and use the correct path to the "NSOCR.DLL" file in the "Bin" (x86 application) or "Bin_64" (x64 application) folder.
If your application uses NSOCR via COM, you need to register "NSOCR.DLL" as a COM server with the "regsvr32.exe" Windows tool. Note that you must specify the path to NSOCR.DLL in the "Bin" folder to register an x86 COM server, or to NSOCR.DLL in the "Bin_64" folder to register an x64 COM server. For .NET applications with the "AnyCPU" target platform, you need to register both x86 and x64 COM servers if Windows x64 is used.
