# C# OCR receipts to text

This guide explains how to convert scanned receipts to searchable PDFs. Nutrient.NET SDK’s (formerly GdPicture.NET) optical character recognition (OCR) engine enables you to recognize text in a receipt and then save the text in a PDF.

## Converting receipts to searchable PDFs

To convert a receipt to a searchable PDF, follow these steps:

1. Create a `GdPicturePDF` object, a `GdPictureImaging` object, and a `GdPictureOCR` object.

2. Select the scanned image of a receipt by passing its path to the `CreateGdPictureImageFromFile` method of the `GdPictureImaging` object.

3. Configure the OCR process with the `GdPictureOCR` object in the following way:
   - Set the image with the `SetImage` method.
   - Set the path to the OCR resource folder with the `ResourceFolder` property. The default language resources are located in `GdPicture.NET 14\Redist\OCR`. For more information on adding language resources, see the [language support](https://www.nutrient.io/guides/dotnet/ocr/language-support.md) guide.
   - With the `AddLanguage` method, add the language resources that Nutrient.NET SDK uses to recognize text in the image. This method takes a member of the `OCRLanguage` enumeration.

4. Run the OCR process with the `RunOCR` method of the `GdPictureOCR` object.

5. Get the result of the OCR process as text with the `GetOCRResultText` method of the `GdPictureOCR` object.

6. Create the output with the `CreateFromText` method of the `GdPicturePDF` object. The first parameter sets the conformance level of the PDF document. This parameter is a member of the `PdfConformance` enumeration. For example, use `PDF` to create a common PDF document.

7. Save the output in a PDF document.

The example below converts a receipt to a searchable PDF:

### C#

```csharp

using GdPicturePDF gdpicturePDF = new GdPicturePDF();
using GdPictureImaging gdpictureImaging = new GdPictureImaging();
using GdPictureOCR gdpictureOCR = new GdPictureOCR();
// Select the image to process.
int imageID = gdpictureImaging.CreateGdPictureImageFromFile(@"C:\temp\source.png");
// Set the OCR parameters.
gdpictureOCR.SetImage(imageID);
gdpictureOCR.ResourceFolder = @"C:\GdPicture.NET 14\Redist\OCR";
gdpictureOCR.AddLanguage(OCRLanguage.English);
// Run the OCR process.
string resID = gdpictureOCR.RunOCR();
// Get the result of the OCR process as text.
string content = gdpictureOCR.GetOCRResultText(resID);
// Save the result in a PDF document.
gdpicturePDF.CreateFromText(PdfConformance.PDF, 595, 842, 10, 10, 10, 10,
    TextAlignment.TextAlignmentNear, content, 12, "Arial", false, false, true, false);
gdpicturePDF.SaveToFile(@"C:\temp\output.pdf");
gdpictureImaging.ReleaseGdPictureImage(imageID);

```

### VB.NET

```vb

Using gdpicturePDF As GdPicturePDF = New GdPicturePDF()
Using gdpictureImaging As GdPictureImaging = New GdPictureImaging()
Using gdpictureOCR As GdPictureOCR = New GdPictureOCR()
    ' Select the image to process.
    Dim imageID As Integer = gdpictureImaging.CreateGdPictureImageFromFile("C:\temp\source.png")
    ' Set the OCR parameters.
    gdpictureOCR.SetImage(imageID)
    gdpictureOCR.ResourceFolder = "C:\GdPicture.NET 14\Redist\OCR"
    gdpictureOCR.AddLanguage(OCRLanguage.English)
    ' Run the OCR process.
    Dim resID As String = gdpictureOCR.RunOCR()
    ' Get the result of the OCR process as text.
    Dim content As String = gdpictureOCR.GetOCRResultText(resID)
    ' Save the result in a PDF document.
    gdpicturePDF.CreateFromText(PdfConformance.PDF, 595, 842, 10, 10, 10, 10,
        TextAlignment.TextAlignmentNear, content, 12, "Arial", False, False, True, False)
    gdpicturePDF.SaveToFile("C:\temp\output.pdf")
    gdpictureImaging.ReleaseGdPictureImage(imageID)
End Using
End Using
End Using

```
