如何在 C# 中定義 BarCode 裁切區域以加快讀取速度

using IronBarCode;

int x1 = 62;
int y1 = 29;
int x2 = 345;
int y2 = 522;

IronSoftware.Drawing.Rectangle crop1 = new IronSoftware.Drawing.Rectangle(x: x1, y: y1, width: x2-x1, height: y2-y1);

Imports IronBarCode

Private x1 As Integer = 62
Private y1 As Integer = 29
Private x2 As Integer = 345
Private y2 As Integer = 522

Private crop1 As New IronSoftware.Drawing.Rectangle(x:= x1, y:= y1, width:= x2-x1, height:= y2-y1)

using IronBarCode;
using System;

int x1 = 62;
int y1 = 29;
int x2 = 345;
int y2 = 522;

IronSoftware.Drawing.Rectangle crop1 = new IronSoftware.Drawing.Rectangle(x: x1, y: y1, width: x2 - x1, height: y2 - y1);

BarcodeReaderOptions options = new BarcodeReaderOptions()
{
    CropArea = crop1
};

var result = BarcodeReader.Read("sample.png", options);
foreach (var item in result)
{
    Console.WriteLine(item.Value);
}

Imports IronBarCode
Imports System

Private x1 As Integer = 62
Private y1 As Integer = 29
Private x2 As Integer = 345
Private y2 As Integer = 522

Private crop1 As New IronSoftware.Drawing.Rectangle(x:= x1, y:= y1, width:= x2 - x1, height:= y2 - y1)

Private options As New BarcodeReaderOptions() With {.CropArea = crop1}

Private result = BarcodeReader.Read("sample.png", options)
For Each item In result
	Console.WriteLine(item.Value)
Next item
