Pdf.Page.Rotate Not Rotating the Document When Page is then converted into BMP Image

Aspose.PDF Product Family

Calling the Rotate Method with the Aspose.Pdf.Rotation.on270 enum does not rotate the page. I am not sure if Aspose is expecting me to re-render the document somehow. I am following this documentation. The code is below:

// The Rotate Page Button That drives Editor rotation
private void tsbRotatePageCCW_Click(object sender, EventArgs e)
{
	_document.RotatePage(Aspose.Pdf.Rotation.on270);
	DisplayPage();
	//pdfViewer.Rotate(System.Drawing.RotateFlipType.Rotate270FlipNone);
}

public void RotatePage(Aspose.Pdf.Rotation rotation)
{
	_pdf.Pages[_currentPage].Rotate = rotation;
	OnSelectedPageChanged(new SelectedPageChangedEventArgs(_currentPage));
}

// Replace Image in PdfViewer with new PDF Image
private void DisplayPage()
{
	pdfViewer.Image = Page.ConvertPDFPagetoImage(_document.CurrentPage.Content);
}

// Converts the Aspose PDF to a BMP Image
public static System.Drawing.Image ConvertPDFPagetoImage(Aspose.Pdf.Page page)
{
	Aspose.Pdf.Devices.BmpDevice imageDevice = new Aspose.Pdf.Devices.BmpDevice();
	using (MemoryStream ms = new MemoryStream())
	{
		// Convert a particular page and save the image to stream
		imageDevice.Process(page, ms);

		return System.Drawing.Image.FromStream(ms);

	}

}

Are you converting PDF Pages into images after rotating them and obtained images are not rotated as per expectation? Can you please share your sample source PDF for our reference so that we can test the scenario in our environment and address it accordingly.
