File Import

You can import images or PDF files into Docutain and do a bunch of things with them, same as after a successful document scan with Docutain's Xamarin Scanner SDK.

Xamarin PDF Creation

Initialization

Initialize the Docutain Xamarin SDK as described here.

File Import

If your simple goal is to import image files and generate a non-searchable (includes no text) PDF file from it, use the Document class.

Xamarin.Forms

using Docutain.SDK.Xamarin.Forms;

if(Document.LoadFile(filePath))
{
    //generate a PDF from the imported file
    var destinationPath = FileSystem.CacheDirectory + "/TestPDF.pdf";
    var pdfFile = Document.WritePDF(destinationPath);
    if(pdfFile != null)
    {
        //do something with the generated pdf file
    } 
    else
    {
        //error occured
        var error = DocutainSDK.LastError;
    }
} 
else
{
    //error occured
    var error = DocutainSDK.LastError;
}

Xamarin.Android

using Docutain.SDK.Xamarin.Android;

if(Document.LoadFile(filePath)) 
{
    //generate a PDF from the imported file
    var destinationPath = FileSystem.CacheDirectory + "/TestPDF.pdf";
    var pdfFile = Document.WritePDF(new Java.IO.File(destinationPath));
    if(pdfFile != null)
    {
        //do something with the generated pdf file
    } 
    else
    {
        //error occured
        var error = DocutainSDK.LastError;
    }
} 
else
{
    //error occured
    var error = DocutainSDK.LastError;
}

Xamarin.iOS

using Docutain.SDK.Xamarin.iOS;

if(Document.LoadFile(fileURL)) 
{
    //generate a PDF from the imported file
    var paths = NSFileManager.DefaultManager.GetUrls(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomain.User);
    var destinationPath = paths[0];
    var pdfFile = Document.WritePDF(destinationPath, "TestPDF");
    if(pdfFile != null)
    {
        //do something with the generated pdf file
    } 
    else
    {
        //error occured
        var error = DocutainSDK.LastError;
    }
} 
else
{
    //error occured
    var error = DocutainSDK.LastError;
}

If you want to create a searchable PDF (includes text), or get the detected data or text of the imported file, use the DocumentDataReader class.

Xamarin.Forms

using Docutain.SDK.Xamarin.Forms;

if(DocumentDataReader.LoadFile(filePath)) 
{
    //generate a searchable PDF from the imported file
    var destinationPath = FileSystem.CacheDirectory + "/TestPDF.pdf";
    var pdfFile = Document.WritePDF(destinationPath);
    //get the detected text 
    var text = DocumentDataReader.GetText();
    //get the detected data
    var data = DocumentDataReader.Analyze(); 
} 
else
{
    //error occured
    var error = DocutainSDK.LastError;
}

Xamarin.Android

using Docutain.SDK.Xamarin.Android;

if(DocumentDataReader.LoadFile(filePath)) 
{
    //generate a searchable PDF from the imported file
    var destinationPath = FileSystem.CacheDirectory + "/TestPDF.pdf";
    var pdfFile = Document.WritePDF(new Java.IO.File(destinationPath));
    //get the detected text 
    var text = DocumentDataReader.GetText();
    //get the detected data
    var data = DocumentDataReader.Analyze(); 
} 
else
{
    //error occured
    var error = DocutainSDK.LastError;
}

Xamarin.iOS

using Docutain.SDK.Xamarin.iOS;

if(DocumentDataReader.LoadFile(fileURL)) 
{
    //generate a searchable PDF from the imported file
    var paths = NSFileManager.DefaultManager.GetUrls(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomain.User);
    var destinationPath = paths[0];
    var pdfFile = Document.WritePDF(destinationPath, "TestPDF");
    //get the detected text 
    var text = DocumentDataReader.GetText();
    //get the detected data
    var data = DocumentDataReader.Analyze(); 
} 
else
{
    //error occured
    var error = DocutainSDK.LastError;
}
