Fix Image Orientation

VB C#

using IronOcr;
using System;

var ocrTesseract = new IronTesseract();
using var ocrInput = new OcrInput();
ocrInput.LoadImage("/path/file.png");

ocrInput.Rotate(90);
ocrInput.Deskew();
ocrInput.Scale(150);

var ocrResult = ocrTesseract.Read(ocrInput);
Console.WriteLine(ocrResult.Text);

Imports IronOcr
Imports System

Private ocrTesseract = New IronTesseract()
Private ocrInput = New OcrInput()
ocrInput.LoadImage("/path/file.png")

ocrInput.Rotate(90)
ocrInput.Deskew()
ocrInput.Scale(150)

Dim ocrResult = ocrTesseract.Read(ocrInput)
Console.WriteLine(ocrResult.Text)

Fix Image Orientation

IronOCR’s OcrInput includes built-in methods to adjust image orientation for optimal OCR accuracy:

Rotate(double degrees): rotates the image clockwise by the given degrees; use negative values for counter-clockwise rotations
Deskew(int maxDeskewAngle = 45): corrects skew up to a maximum angle (default 45°); returns true if correction was applied
Scale(int percent, bool scaleCrop = true): resizes the image proportionally (e.g. 150 for 150%)
