x64 version of 3.0.0 does work

[charlesw]

The x64 version of 3.0.0 doesn't work as it's currently throwing the following error:

System.Reflection.TargetInvocationException occurred
  HResult=-2146232828

This is because it appears that the x86 version of liblept171.dll has been packaged as the x64 version.

I am still getting this exception, how to resolve it. Can you please update nuget package?

[charlesw]

The x64 bit issue should now be resolved in vs 3.0.1 (sample are working as expected). Note that #231 is still an issue, though I cannot reliably reproduce it.

[dtosato]

I still have the problem with the last nuget package.

[garora]

V3.0.1 is still having same issue as v3.0.0

You might need to reinstall the library as sometimes nuget doesn't seem to replace the unmanaged dlls (x64\liblept171.dll && x64\libtesseract304.dll). If your still having issues can you please include the exception.

[garora]

Thanks its working now.looks like it unresolved a new issue. I m getting
wrong co ordinates of words. We are using this to highlight words for
search.

I just ran a test and am getting the correct coordinates for the words using the console sample:

using (var engine = new TesseractEngine(@"./tessdata", "eng", EngineMode.Default))
{
    using (var img = Pix.LoadFromFile(testImagePath))
    {
        using (var page = engine.Process(img))
        {
            var text = page.GetText();
            Console.WriteLine("Mean confidence: {0}", page.GetMeanConfidence());

            Console.WriteLine("Text (GetText): \r\n{0}", text);
            Console.WriteLine("Text (iterator):");
            using (var iter = page.GetIterator())
            {
                iter.Begin();

                do
                {
                    do
                    {
                        do
                        {
                            do
                            {
                                if (iter.IsAtBeginningOf(PageIteratorLevel.Block))
                                {
                                    Console.WriteLine("<BLOCK>");
                                }

                                Console.Write(iter.GetText(PageIteratorLevel.Word));
                                Rect bounds;
                                if(iter.TryGetBoundingBox(PageIteratorLevel.Word, out bounds)) {
                                    Console.Write(bounds);
                                }
                                Console.Write(" ");

                                if (iter.IsAtFinalOf(PageIteratorLevel.TextLine, PageIteratorLevel.Word))
                                {
                                    Console.WriteLine();
                                }
                            } while (iter.Next(PageIteratorLevel.TextLine, PageIteratorLevel.Word));

                            if (iter.IsAtFinalOf(PageIteratorLevel.Para, PageIteratorLevel.TextLine))
                            {
                                Console.WriteLine();
                            }
                        } while (iter.Next(PageIteratorLevel.Para, PageIteratorLevel.TextLine));
                    } while (iter.Next(PageIteratorLevel.Block, PageIteratorLevel.Para));
                } while (iter.Next(PageIteratorLevel.Block));
            }
        }
    }
}

Note that the bounds are measured in pixels relative to the top left corner of the source image. If your using a region of interest I think the coords will be relative to the region not the source image, though I haven't checked this...

[garora]

Let me recheck the code , I did not change the code since 3.0.0 I hope the
API is same. I m only concernef about X2 which always returns as Zero.
Thanks for your reply. Let me work it out at my end first and will update
accordingly.
