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);
}Imports IronOcr
Private Ocr = New IronTesseract()
Using Input = New OcrInput()
' a 41% improvement on speed by specifiying a pixel region
Dim ContentArea = New System.Drawing.Rectangle() With {
.X = 215,
.Y = 1250,
.Height = 280,
.Width = 1335
}
Input.AddImage("img/example.png", ContentArea)
Dim Result = Ocr.Read(Input)
Console.WriteLine(Result.Text)
End Using
