Page Orientation.

[[email protected]]

I'm trying to apply a rubberstamp in to a document where the first page was rotate so the location of coordinate (0,0) is on the top left corner of the page on the other pages it is locate on the top right corner. How can i do to make sure that I was going to apply the stamp into the same position besides the page orientation?


Thank You

Hello,

Thanks for your inquiry.
You can try the following sample code to apply the rubberstamp into the same position. If there is any question, please provide your testing PDF file to help us further investigate it. You could send it to us via email ([email protected]).

Code: Select all

 //load original pdf
 PdfDocument doc = new PdfDocument();
 doc.LoadFromFile(@"test.pdf");
 //create a new pdf
 PdfDocument newPdf = new PdfDocument();
 //load the image
 PdfImage image = PdfImage.FromFile(@"logo.png");
 foreach (PdfPageBase page in doc.Pages)
 {
     PdfPageBase newPage;
     //judge if the page rotated
     if (page.Rotation == PdfPageRotateAngle.RotateAngle90)
         newPage = newPdf.Pages.Add(new SizeF(page.Size.Height, page.Size.Width), new PdfMargins(0));
     else if (page.Rotation == PdfPageRotateAngle.RotateAngle270)
         newPage = newPdf.Pages.Add(new SizeF(page.Size.Height, page.Size.Width), new PdfMargins(0));
     else
         newPage = newPdf.Pages.Add(page.Size, new PdfMargins(0));
     page.CreateTemplate().Draw(newPage, new PointF(0, 0));
     //add an image stamp
     PdfRubberStampAnnotation loStamp = new PdfRubberStampAnnotation(new RectangleF(new PointF(10, 300), new SizeF(60, 60)));
     PdfAppearance loApprearance = new PdfAppearance(loStamp);
     PdfTemplate template = new PdfTemplate(160, 160);
     template.Graphics.DrawImage(image, 0, 0);
     loApprearance.Normal = template;
     loStamp.Appearance = loApprearance;
     newPage.AnnotationsWidget.Add(loStamp);
 }
 newPdf.SaveToFile("result.pdf",Spire.Pdf.FileFormat.PDF);

Thanks for your reply, I'm testing it right now.

I did a few changes in the code you sent to me and it works.

Thank You very much

Hi,

Today for the first time I tested this code with a PDF file that has bookmark on, I found out the this code is not carrying over the bookmark. Do you have any idea on how to fix it?


Thank you

Test file attached.

Hello,

Thank you for contacting.
I regret to tell you that our Spire.PDF doesn't support keeping the bookmarks by page.CreateTemplate().Draw(newPage, new PointF(0, 0)) method above at present.

Hi,

There is any other way to deal with the page orientation?I've been doing a few more tests what I found out was that the bookmark is removed in that part of the code:
PdfPageBase newPage;
                     if (page.Rotation == PdfPageRotateAngle.RotateAngle90)
                         newPage = newPdf.Pages.Add (new SizeF (page.Size.Height, page.Size.Width), new PdfMargins (0));
                     else if (page.Rotation == PdfPageRotateAngle.RotateAngle270)
                         newPage = newPdf.Pages.Add (new SizeF (page.Size.Height, page.Size.Width), new PdfMargins (0));
                     else
                         newPage = newPdf.Pages.Add (page.Size, new PdfMargins (0));
                     page.CreateTemplate () .Draw (newPage, new PointF (0, 0));

If I just load the PDF file and add a note and then save it, the bookmark stays there.

Thank You

Hello,

Sorry there is no other way to deal with the page orientation at present. Our Spire.PDF provides the following method to copy bookmarks from one PDF to another PDF. Testing my sample PDF (see attachment) with bookmarks has no problem. However, the bookmarks in your PDF (8BKM0060-011 DWG.pdf) have particularity, they don't have actions, that leads to no connection between PDF contents and the bookmarks after copying. I have posted your PDF to our Dev team, they will analyze it further and investigate if there is any solution for you. Sorry for the inconvenience caused.

Code: Select all

//load original pdf
PdfDocument doc = new PdfDocument();
doc.LoadFromFile("MySample.pdf");
//create a new pdf
PdfDocument newPdf = new PdfDocument();
foreach (PdfPageBase page in doc.Pages)
{
    PdfPageBase newPage;
    if (page.Rotation == PdfPageRotateAngle.RotateAngle90)
        newPage = newPdf.Pages.Add(new SizeF(page.Size.Height, page.Size.Width), new PdfMargins(0));
    else if (page.Rotation == PdfPageRotateAngle.RotateAngle270)
        newPage = newPdf.Pages.Add(new SizeF(page.Size.Height, page.Size.Width), new PdfMargins(0));
    else
        newPage = newPdf.Pages.Add(page.Size, new PdfMargins(0));
    //draw original page to new page
    page.CreateTemplate().Draw(newPage, new PointF(0, 0));
}
//get bookmarks from original pdf
var bms = doc.Bookmarks;
for (int i = 0; i < bms.Count; i++)
{
    //add parent bookmark
    PdfDestination vendorBookmarkDest = new PdfDestination(bms[i].Destination.Page, bms[i].Destination.Location);
    PdfBookmark vendorBookmark = newPdf.Bookmarks.Add(bms[i].Title);
    vendorBookmark.Color = bms[i].Color;
    vendorBookmark.DisplayStyle = bms[i].DisplayStyle;
    vendorBookmark.Action = new PdfGoToAction(vendorBookmarkDest);

    for (int j = 0; j < bms[i].Count; j++)
    {
        //add child bookmark
        PdfDestination partBookmarkDest = new PdfDestination(bms[i][j].Destination.Page, bms[i][j].Destination.Location);
        PdfBookmark partBookmark = vendorBookmark.Add(bms[i][j].Title);
        partBookmark.Color = bms[i][j].Color;
        partBookmark.DisplayStyle = bms[i][j].DisplayStyle;
        partBookmark.Action = new PdfGoToAction(partBookmarkDest);
    }
}
//save to file
newPdf.SaveToFile("result.pdf", FileFormat.PDF);

Hi Nina,

I tested the piece of code that you posted, It is duplicating the Bookmarks end not all of the links are working after processed the PDF file.

foreach (PdfPageBase page in document.Pages)
{
PdfPageBase newPage;
if (page.Rotation == PdfPageRotateAngle.RotateAngle90)
newPage = newPdf.Pages.Add(new SizeF(page.Size.Height, page.Size.Width), new PdfMargins(0));
else if (page.Rotation == PdfPageRotateAngle.RotateAngle270)
newPage = newPdf.Pages.Add(new SizeF(page.Size.Height, page.Size.Width), new PdfMargins(0));
else
newPage = newPdf.Pages.Add(page.Size, new PdfMargins(0));
page.CreateTemplate().Draw(newPage, new PointF(0, 0));

//get bookmarks from original pdf
var bms = document.Bookmarks;

for (int w = 0; w < bms.Count; w++)
{
//Add parent bookmark
//PdfDestination vendorBookmarkDest = new PdfDestination(bms[w].Destination.Page, bms[w].Destination.Location);
PdfDestination vendorBookmarkDest = bms[w].Destination;

vendorBookmarkDest.Page = newPage;
PdfBookmark vendorBookmark = newPdf.Bookmarks.Add(bms[w].Title);
vendorBookmark.Color = bms[w].Color;
vendorBookmark.DisplayStyle = bms[w].DisplayStyle;
vendorBookmark.Action = new PdfGoToAction(vendorBookmarkDest);

for (int j = 0; j < bms[w].Count; j++)
{
//Add child bookmark
//PdfDestination partBookmarkDest = new PdfDestination(bms[w][j].Destination.Page, bms[w][j].Destination.Location);
PdfDestination partBookmarkDest = bms[w][j].Destination;
partBookmarkDest.Page = newPage;
PdfBookmark partBookmark = vendorBookmark.Add(bms[w][j].Title);
partBookmark.Color = bms[w][j].Color;
partBookmark.DisplayStyle = bms[w][j].DisplayStyle;
partBookmark.Action = new PdfGoToAction(partBookmarkDest);
}
}


Take a look in the attached files.

Thank You

I just figured out that if the PDF file has only one page the code works just file.
