Hi, i currently use the demo version to see if any usage of the OCR library can be of any use in our process.

I tried every single OCR demo application in the CSharp V2.0 version and all worked fine.

I am currently doing some programmation try and i have the following exception in my software.

"Scan soft dll are not loaded"

This exception is raised when i try to call the recognize method of the RasterOcr object.

I presume i did everything fine because the findzone method of the RasterOcr object find every single zone your program finds for the same bmp.

Does any one avec any idea ?

 

(Sorry for my bad english and poor explanation of the problem)

Thanks you but it seems that i have the latest versions. [LEADTOOLS EVAL 14.5]

For the OCR demo application i try to generate i add the following references:

using Leadtools;

using Leadtools.Codecs;

using Leadtools.Demos;

using Leadtools.ImageProcessing;

using Leadtools.Ocr;

using Leadtools.WinForms;

In my main function i do the following:

Support.Unlock(false);

DemosGlobal.SetupCodecsPath(); // I checked all the path are corrects. (I've created my demo project in the same directory as the demo project.)

RasterCodecs _codecs = new RasterCodecs();

RasterOcr _rasterOcr = new RasterOcr();

_rasterOcr.StartUp();

CodecsImageInfo oInfo = _codecs.GetInformation(@"c:\Images\Image2.bmp", true);

_codecs.Options.Load.Passes = 2;   // those values have been found by debugging the official demo appications

_codecs.Options.Load.Rotated = true; // those values have been found by debugging the official demo appications

_codecs.Options.Load.Compressed = true; // those values have been found by debugging the official demo appications

IRasterImage _image = _codecs.Load(@"c:\\Image2.bmp", 0, CodecsLoadByteOrder.BgrOrGray, 1, 1);

_rasterOcr.AddPage(_image, 0);

_rasterOcr.ActivePage = 0;

_rasterOcr.EnableSubSystem = true;

_rasterOcr.EnableCorrection = true;

_rasterOcr.SpellLanguageID = RasterOcrLanguage.English;

_rasterOcr.EnableZoneForceSingleColumn = true;

_rasterOcr.ZoneParser = RasterOcrPageParser.Auto;

_rasterOcr.FindZones(0);

Int32 nCount = _rasterOcr.GetZonesCount(0); // This function works well and have the same behavior than the official ocr demo one.

_rasterOcr.Recognize(0, 1); // This function raise the "Scansoft dll are nor loaded" exception... [:'(]

String strcontent = _rasterOcr.SaveResultsToMemory();

Console.WriteLine(strcontent);

_rasterOcr.ShutDown();

Does anyone have any idea ?

Hello,

I think the problem on your machine might be related to one of the following:

(1) Please make sure that you set the RasterCodecs.CodecsPath property points to the correct path on the redist as follows:
+----------------------------+
RasterCodecs.CodecsPath = @"D:\Program Files\LEAD Technologies, Inc\LEADTOOLS 14.5\Redist\DOTNET\v20";    
+----------------------------+

(2) Please make sure to include the following lines of code to your project:
+----------------------------+
RasterOcr.RecognizeStatus += new RasterOcrRecognizeStatus(ocr_RecognizeStatus);
RasterOcr.EnableSubSystem = true;
RasterOcr.EnableCorrection = true;
RasterOcr.SpellLanguageID = RasterOcrLanguage.Auto;
RasterOcr.RecognitionDataFileName = @"c:\test.rdf";
+----------------------------+

Please try the above instructions and let me know what will happen with you.

Thanks,

Thank you,

It finally works now...

The error was due (stragely) to the fact that i didn't initialized the RasterOcr.RecognitionDataFileName variable.

Don't ask me why it shouts that the Scansoft dll were not loading...

Thank you very much ^^

I had the same problem with the scansoft dll error message.  When I set the

rasterOCR.RecognitionDataFileName

to a valid file name, it works.  Without that var set, it throws the aforementioned error.  This response was repeatable.  I saw that one other response to this question found this solution. I am just verifying that it also worked for me.
