Save the rotated file effortlessly with our example." --- # Automatically rotate pages of a multipage TIFF file using OCR and VB.NET This example shows how to automatically rotate pages of a multipage TIFF file with help of the OCR Tesseract engine method. After the successful rotation of all pages, the source file is saved to the destination file. [Get Started](https://www.nutrient.io/sdk/dotnet/getting-started.md) [All Samples](https://www.nutrient.io/guides/dotnet/samples.md) [Download](https://www.nutrient.io/guides/dotnet/downloads.md) [Launch Demo](https://www.nutrient.io/demo/) --- ### C# [C#](https://www.nutrient.io/guides/dotnet/samples/auto-rotate-tiff-cs.md) ### VB.NET [VB.NET](https://www.nutrient.io/guides/dotnet/samples/auto-rotate-tiff-vbnet.md) ```vb 'We assume that GdPicture has been correctly installed and unlocked. Dim filepath As String = "multipage.tif" Dim destpath As String = "output.tif" 'Specify your path. Dim DICT_PATH As String = "C:\GdPicture.NET 14\Redist\OCR" 'Specify your language.
