Overview

How to get skew angle using C#

We offer advanced tools and technologies for accurate skew angle detection of images. Our cutting-edge algorithms analyze images to determine their skew angles with precision and efficiency.

To run the examples, you just need to download the Aspose.OCR tools with the following links:

Command line tools

GetSkew project



Run program in Command Prompt


  GetSkew

or

Run program in Command Prompt if you want to use own image (document)


  GetSkew folder/image.png




Recognition result

PropertyTypeDescription
AnglefloatSkew angle in degrees.
ImageIndex   intSequence number of the image on the page. When working with single-page images, this value is always 0.
PageintPage number. When working with single-page images, this value is always 0.
Sourcestring   The full path of the source file. If the file is provided as a MemoryStream object, an array of pixels, or a Base64 string, this value will be empty.


This sample code shows how to get skew angle


	  // Set the license file
            //License lic = new License();
            //lic.SetLicense("Aspose.Total.lic");

            // Create AsposeOcr instance.
            // You can use the overloaded constructor to set characters restriction.
            AsposeOcr api = new AsposeOcr();

            // Create OcrInput object to containerize images
            OcrInput input = new OcrInput(InputType.SingleImage);
            input.Add(fileName);

            // You can put in parameters MemoryStream with image
            // The result is the degree of skew
            List<SkewOutput> result = api.CalculateSkew(input);
            Console.WriteLine("RESULT");
            Console.ResetColor();
            Console.WriteLine("------------------------------------------------------------------------------");

            Console.WriteLine("SKEW IMAGE 1:");
            Console.WriteLine(result[0].Angle);

            input.Clear();
