Crop Pdf page

Aspose.PDF Product Family
1 
Hello, 
I'm trying to crop a page in a pdf file.
I'm using the following method to do it, but the saved document is wrong, the page cropped 
shows different parts of the page.
if (stream != null)
{

Aspose.Pdf.Document document = new Aspose.Pdf.Document(filePath);

Aspose.Pdf.Rectangle pageRect = new Aspose.Pdf.Rectangle(page.X, page.Y, page.Width, page.Height);

document.Pages[page.PageIndex].CropBox = pageRect;


Page newPage = document.Pages[page.PageIndex];


Resolution resolution = new Resolution(300);


JpegDevice jpegDevice = new JpegDevice(resolution, 100);


jpegDevice.Process(newPage, stream);


document.Save(outputStream);


}
I think the Rectangle parameters are wrong, can someone help me to pass the right parameters ?
Thank you in advanced

I was able to work around to crop image using Aspose.Pdf.Facades.PdfFileMend.

But now i’m having difficulty to set the right coordinates to my cropped page. 

 public MemoryStream CropPage(string filePath, FilePage page)

{

MemoryStream retVal = new MemoryStream();

        <span style="color:blue;">this</span>.DeletePage(filePath, page.PageIndex);

        <span style="color:#2b91af;">MemoryStream</span> imageStream = <span style="color:#2b91af;">FileHelper</span>.DownloadFile(page.PageUrl);

        <span style="color:blue;">if</span> (!<span style="color:blue;">string</span>.IsNullOrEmpty(filePath))
        {
            Aspose.Pdf.<span style="color:#2b91af;">Document</span> pdfDocument = <span style="color:blue;">new</span> Aspose.Pdf.<span style="color:#2b91af;">Document</span>(filePath);
            <span style="color:#2b91af;">PageCollection</span> pageCollection = pdfDocument.Pages;
            <span style="color:#2b91af;">Page</span> pdfPage = pageCollection[1];
            <span style="color:#2b91af;">Page</span> newPage = pdfDocument.Pages.Insert(page.PageIndex);
            newPage.SetPageSize((<span style="color:blue;">double</span>)pdfPage.Rect.Width, (<span style="color:blue;">double</span>)pdfPage.Rect.Height);
            Aspose.Pdf.Facades.<span style="color:#2b91af;">PdfFileMend</span> fileMend = <span style="color:blue;">new</span> Aspose.Pdf.Facades.<span style="color:#2b91af;">PdfFileMend</span>(pdfDocument, retVal);
            <span style="color:blue;">using</span> (imageStream)
            {
                <span style="color:#2b91af;">MemoryStream</span> stream = imageStream;
                <span style="color:blue;">float</span> pdfPageHeightLLY = (<span style="color:blue;">float</span>)page.Height;
                <span style="color:blue;">float</span> pdfPageWidthLLX = (<span style="color:blue;">float</span>)0;
                <span style="color:blue;">float</span> pdfPageHeightURY = (<span style="color:blue;">float</span>)pdfPage.Rect.Height + (<span style="color:blue;">float</span>)page.Y;
                <span style="color:blue;">float</span> pdfPageWidthURX = (<span style="color:blue;">float</span>)page.X;
                <span style="color:blue;">if</span> (imageStream != <span style="color:blue;">null</span>)
                {
                    fileMend.AddImage(imageStream, page.PageIndex, pdfPageWidthLLX, pdfPageHeightLLY, pdfPageWidthURX, pdfPageHeightURY);
                }
                stream = <span style="color:blue;">null</span>;
            }
            pdfDocument.Save(filePath);
            fileMend.Close();

        }

        <span style="color:blue;">return</span> retVal;
    }</pre></div><div>I want the cropped image to be saved at (0,0)</div><div>Any idea that might help?</div><div>thanks in advanced</div>

I Found it!

My coordinate was wrong and I had other style that was changing the display I wanted

 float pdfPageHeightLLY = (float)pdfPage.Rect.Height - (float)page.Height;

float pdfPageWidthLLX = (float)0;

float pdfPageHeightURY = (float)pdfPage.Rect.Height;

float pdfPageWidthURX = (float)page.Width;
