OCR a Region of an Image
This examples renders a 41% speed improvement by choosing a specific area of an image to perform OCR in .NET.
These are called ContentAreas or CropAreas.
using IronOcr; var Ocr = new IronTesseract(); using (var Input = new OcrInput()) { // a 41% improvement on speed by specifiying a pixel region var ContentArea = new System.Drawing.Rectangle() { X = 215, Y = 1250, Height = 280, Width = 1335 }; Input.AddImage("img/example.png", ContentArea); var Result = Ocr.Read(Input); Console.WriteLine(Result.Text); }
