File Import

You can import images or PDF files into Docutain and do a bunch of things with them.

Windows PDF Creation

Windows Text Detection

Windows Data Extraction

Besides PDF files, the following image file types are currently supported:

• BMP
• JPG
• JPEG
• PNG
• TIFF
• HEIC

The Docutain Windows SDK needs to be initialized prior to using any functionality of it as described here.

In order to import a file, use the Document.Load() method.

The following shows an example importing a file that got picked from an OpenFileDialog and generating a PDF out of it:

//open file dialog to pick a file
using (OpenFileDialog ofd = new OpenFileDialog())
{
    ofd.Filter = "Supported files (*.PDF; *.JPG; *.JPEG; *.PNG; *.TIF; *.TIFF; *.HEIC)|*.PDF; *.JPG; *.JPEG; *.PNG; *.TIF; *.TIFF; *.HEIC";
    ofd.Filter += "|PDF files (*.PDF)|*.PDF|JPG files (*.JPG; *.JPEG)|*.JPG; *.JPEG|PNG files (*.PNG)|*.PNG|TIF files (*.TIF; *.TIFF)|*.TIF; *.TIFF|HEIC files (*.HEIC)|*.HEIC";
    ofd.FilterIndex = 1;
    ofd.RestoreDirectory = false;

    if (ofd.ShowDialog() == DialogResult.OK)
    {
        //load a document from selected file path
        if (!await Docutain.SDK.Windows.Document.Load(ofd.FileName))
        {
            string error = DocutainSDK.GetLastError();
            ...
            return;
        }
        //generate PDF from currently loaded document and save it to the selected path
        string filePathGeneratedPDF = Docutain.SDK.Windows.Document.WritePDF(filePathPDF, false, Docutain.SDK.Windows.Document.PDFPageFormat.FitToPages);
        if (string.IsNullOrEmpty(filePathGeneratedPDF))
        {
            string error = DocutainSDK.GetLastError();
            ...
        }
    }
}

Sample for getting the detected text and the analyzed data:

if (await Docutain.SDK.Windows.Document.Load(file))
{
    string text = Document.Text(-1);
    string documentData = Document.Analyze();
}
else
{
    string error = DocutainSDK.GetLastError();
}

You can also load a file from a Stream or a byte[].
