I tried to update the bookmarks so of an existing pdf so that it`s destinations all will keep the zoom factor the user has selected when following the bookmark (as know as inherit zoom)

My code passes throuh the Outlines Collections, checks wether the Destination is an Aspose.Pdf.InteractiveFeatures.XYZExplicitDestination and if not, creates a new XYZExplicitDestination and assigns it to the destination member of the Outline (alternatively, I tried to assign a new GoToAction to the action member). To figure out the changed bookmark, I also change the bockmark text.

When the PDF is saved, the text of the respective bookmarks is changed but the destinations remain unchanged!

I added my code as attachment (as it is a bit lengthy, the important part is method setInheritZoom)!

Can anyone figure out what is wrong with my code?

Thanks

I created a PDF using the Aspose.Pdf.Generator.Pdf and saved it to a MemoryStream.

I created a Aspose.Pdf.Facades.Form using that MemoryStream.

When I tried to get the names of the fields using FieldNames property of the Form, it returned an empty list.

GetField method also fails when I look for the names of the fields.

I do not have this problem when I use the FormEditor to create the fields. However, I am using the generator to generate my PDF.

I would like some help getting this to work.

I have also included a sample C# file I wrote using Window Forms Application.

PDF-Form field names with leading underscore

≪ Previous: FieldNames Can't be Found!

Hello experts,

I'm using the fillable pdf formular in the attachment. This worked fine with previous versions of Aspose.PDF, but as soon as I update to the newest Library (9.3) I get a NullReferenceExpetion in the library with no change my code.

I try to fill the field with name "44.name_vorname". I can see the field in the list of the form.FieldNames list but then when the FillField mehtod is called a null reference exception is thrown. As I can see in Adobe Acrobat all the fields are defined with a leading underscore (so the "real" name is "_44.name_vorname"), maybe the leading underscore leads to the problem?

Thanks for any help,

Hi,

how can I insert/convert an image into PDF with some size adjustment?

I mean I want to resize the image if the size is bigger than the A4 page size to fit it into the page.

If the image size is smaller than A4, the image should be centered.

Is there any way to do that?

Thank you,

Watermark text stamp affecting the main body of a pdf page

June 5, 2014, 7:20 am

≫ Next: Upgraded .lic file throws "the license is not valid for this product" error

≪ Previous: Issue in rendering \n using TextFragment

I am using text stamps to add annotations to an existing PDF file. One of the stamps is creating a watermark across the page. This is added with :

oTextStamp = New TextStamp("RESTRICTED")

oTextStamp.Background = False

oTextStamp.TextState.Font = Aspose.Pdf.Text.FontRepository.FindFont("Helvetica")

oTextStamp.TextState.FontSize = 108

oTextStamp.XIndent = 7

oTextStamp.YIndent = 36

oTextStamp.RotateAngle = 55

oTextStamp.Opacity = 0.1

oTextStamp.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Black)

oCurrPage.AddStamp(oTextStamp)

On some scanned in PDF files, although the result looks fine, when the resulting page is printed, the text that is underneath the 'RESTRICTED' word is no longer readable.

This seems to print out wrongly using versions of Acrobat Reader except for the latest Version XI.

Most pdf files that are stamped are also fine, it seems to be something to do with how they are scanned.

I attach a copy of an original file, stamped file and a picture of the printed page.

Can you suggest any different way that I can stamp a word across the pages that would get around this problem ?

Thanks

≪ Previous: Font 'Times New Roman' not found. Please make sure the customer font file is correctly set.

Hello,

are there any limitations regarding dimensions of a PDF document created with Aspose.Net.PDF?

I'm trying to convert a very large XPS Document into a PDF using the following code.

using (var pdf = new Document(source, new XpsLoadOptions()))

{

pdf.Save(file);

}

The XPS document itself is about 130 MB file size (containing many images) and the dimensions are about 180.000 x 80.000 units. I did a test which takes very very long time with an average memory usage of about 1 GB ram and about 35% CPU consumption on an iCore 5. The result is a blank page.

If I know the limitations, maybe I can scale down the XPS to the maximum dimension.

Thanks

≫ Next: PDF file increse file size after Optimization

≪ Previous: Limitations for PDF documents created with Aspose.PDF

We use Aspose.PDF for converting various image files to PDF. Most all images we convert have no problem. But we've recently encountered a couple of .jpg image files that will not convert.
The files do open successfully in MS Paint and Windows Photo Viewer.

I've attached one of those for your testing (wont_convert.jpg).
Oddly enough, I have taken that same attached file and (using MS Paint) converted it to:
- .tif
- .png
- .bmp
Those all successfully convert to PDF using Aspose.PDF.

Finally, if I re-convert the .png back to .jpg (again using MS Paint), the resulting .jpg file successfully converts to PDF with Aspose.PDF.

So it appears there is something in the initial format of these troublesome files that Aspose is not recognizing.

Here's a snippet of code showing how we use Aspose.PDF for image conversion:

//Instantiate a Pdf object by calling its empty constructor
Aspose.Pdf.Generator.Pdf pdfGen = new Aspose.Pdf.Generator.Pdf();

//Create a section in the Pdf object
Aspose.Pdf.Generator.Section sec1 = pdfGen.Sections.Add();

//Create an image object in the section
Aspose.Pdf.Generator.Image image1 = new Aspose.Pdf.Generator.Image(sec1);

//Add image object into the Paragraphs collection of the section
sec1.Paragraphs.Add(image1);

//Set the path of image file
image1.ImageInfo.File = file;

//Set the type of image using ImageFileType enumeration
string ext = Path.GetExtension(file).ToUpper();
switch (ext)
{
case "TIFF":
case "TIF":
image1.ImageInfo.ImageFileType = Aspose.Pdf.Generator.ImageFileType.Tiff; break;
case "BMP":
image1.ImageInfo.ImageFileType = Aspose.Pdf.Generator.ImageFileType.Bmp; break;
case "GIF":
image1.ImageInfo.ImageFileType = Aspose.Pdf.Generator.ImageFileType.Gif; break;
case "JPG":
case "JPEG":
image1.ImageInfo.ImageFileType = Aspose.Pdf.Generator.ImageFileType.Jpeg; break;
case "PNG":
image1.ImageInfo.ImageFileType = Aspose.Pdf.Generator.ImageFileType.Png; break;
}

Hi,

I have raised this earlier. In Pdf portfolio files, we need to have the capability to split the window vertically by default. The default behavior is a horizontal split and it is very less usable and the scroll bars does not work either.

So we should have an option of opening the files with windows split vertically. Do you have an estimated time of when this will be available?

The default behavior makes the pdf portfolio almost unusable and this is a critical requirement for us.

Waiting for your response on this.
