{
    this.label = new System.Windows.Forms.Label();
    this.btnCreate = new System.Windows.Forms.Button();
    this.SuspendLayout();
    // 
    // label
    // 
    this.label.Location = new System.Drawing.Point(0, 40);
    this.label.Name = "label";
    this.label.Size = new System.Drawing.Size(426, 35);
    this.label.TabIndex = 0;
    this.label.Text = "Click the button to Convert Excel document to Image generated by Essential XlsIO";
    this.label.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
    // 
    // btnCreate
    // 
    this.btnCreate.Location = new System.Drawing.Point(90, 110);
    this.btnCreate.Name = "btnCreate";
    this.btnCreate.Size = new System.Drawing.Size(223, 36);
    this.btnCreate.TabIndex = 1;
    this.btnCreate.Text = "Convert Excel to Image";
    this.btnCreate.Click += new System.EventHandler(this.btnConvert_Click);
    // 
    // Form1
    // 
    this.ClientSize = new System.Drawing.Size(450, 150);
    this.Controls.Add(this.label);
    this.Controls.Add(this.btnCreate);
    this.Name = "Form1";
    this.Text = "Convert Excel document to Image";
    this.ResumeLayout(false);
}

using (ExcelEngine excelEngine = new ExcelEngine())
{
    IApplication application = excelEngine.Excel;
    application.DefaultVersion = ExcelVersion.Xlsx;
	IWorkbook workbook = application.Workbooks.Open("Sample.xlsx");
    IWorksheet worksheet = workbook.Worksheets[0];

    //Convert the Excel to Image
    Image image = worksheet.ConvertToImage(1, 1, 20, 4);

    //Save the image as jpeg
    image.Save("Sample.Jpeg", ImageFormat.Jpeg);
}
