How to set the margins and draw the margins?

And, is there any strategy to identify where should we draw vertical lines?
Responde

RE: PDF4NET Adrian Marin 12-Jan-2012 07:49:16

Hello,

The margins are where your application logic dictates. The page canvas allows free text drawing, you draw the text in a textbox and place it on a page. Please take a look at TextBoxes sample for more details.

The DrawHTMLTextBox does not support all HTML tags, only a few text formatting tags are supported, such as b, i, u, font.
The HTML formatted text must also be XML well formed.

PDF4NET cwatts [ON, Canada] 02-Nov-2011 22:02:30

I have a process where I am using PDF4NET to merge a bunch of pdf files. I have approx 4500 files that account for approx 366MB of data. I am calling MergeFiles passing a source file destination name, and an array of file locations to merge. This is causing OutOfMemory exceptions with the aspnet worker process. Is there a more efficient way to merge these files?
Responde

RE: PDF4NET Adrian Marin (O2 Solutions) 03-Nov-2011 09:09:42

Hello,

The MergeFiles creates the merged document in memory by default and this can cause the memory exceptions if the document is very large. The solution is to implement a merge process that takes each file, appends it to destination document, saves the appended pages and then goes to next file. In this way only a single file is kept in memory at a time.

I did try a solution where I reduced the number of items I passed into the Merge process, but I made it call still with roughly 500 each time. Are you saying that if I have 4500 PDFs to merge I should call Merge 4500 times, each time passing the new file path, and the file path to merge into, .... and that should reduce memory usage?
Responde

RE: RE: RE: PDF4NET Adrian Marin (O2 Solutions) 04-Nov-2011 16:09:14

A custom merge procedure can be implemented like this:
public void MergeFiles(string output, string[] input)
{
FileStream outputStream = new FileStream(output, FileMode.Create, FileAccess.ReadWrite, FileShare.None);

PDFDocument doc = new PDFDocument();
doc.BeginSave(outputStream);

for (int i = 0; i < input.Length; i++)
{
PDFFile file = PDFFile.FromFile(input[i]);
PDFImportedPage[] pages = file.ExtractPages();
file.Close();

int startPage = doc.Pages.Count;
for (int j = 0; j < pages.Length; j++)
{
doc.Pages.Add(pages[j]);
}
int endPage = doc.Pages.Count - 1;
for (int j = startPage; j <= endPage; j++)
{
doc.SavePage(j);
}
}

doc.EndSave();
outputStream.Flush();

PDF4NET daniel.hoelting [NE, USA] 02-Aug-2011 20:04:06

I am trying to calculate the maximum font size for my content before writing it to the pdf.

while (lineWidth > pdfPg.Width - _wdthMarg | linesHeight > pdfPg.Height - _htMarg)
{
// adjust font size
newFntSize -= 1f;

// get values again to check against allowed sizes
textFont = new PDFFont(FontFace.Courier, newFntSize);
lineWidth = (float)textFont.MeasureString(line);
linesHeight = newFntSize * YLines;
}

When I create the pdfPg, I'm getting the default values of 612x792 for portrait. I adjust my font until it 'fits', but after writing out to the pdf and displaying it, the content only fills about 2/3 of the width and 1/2 of the height. I am trimming the content to eliminate whitespace at the end of the line.

I read in another post about how the size of the page is default until a document is loaded. Is the size default until content is written to it?

After you load the files in a PDFDocument, the Width and Height properties of the page will give you the values you want:
document.Pages[0].Width and document.Pages[0].Height.
The PageSize, PageWidth and PageHeight properties on the PDFDocument are default values to be used when creating new pages. Actual page width and height are given by corresponding page properties.

The .NET Garbage Collector has a non-deterministic behavior, the exact moment when the memory is actually released is unknown.

I am going to create a new document and keep adding each and every page of already opened document (after manipulation) to a new document and size of the new document keeps increasing and not sure at what point am getting OutofMemory Exception.

Hello Hiran,

#1 - search preferences like whole word search are not support yet. The search text is found whether it is a whole word or part of a larger word.
#2 - The bounding box of text runs and search results uses the text baseline as bottom edge. This is why the lower part of g, p, falls outside. In the future we plan to add support for extended bounding boxes so the lower parts of these letters are also included.

DirectCast(formField.Widgets(0).BorderColor, O2S.Components.PDF4NET.Graphics.PDFRgbColor).R = 0
DirectCast(formField.Widgets(0).BorderColor, O2S.Components.PDF4NET.Graphics.PDFRgbColor).G = 0
DirectCast(formField.Widgets(0).BorderColor, O2S.Components.PDF4NET.Graphics.PDFRgbColor).B = 0

I am getting object refernce error. I am able to assign other properties like font and font size etc. But the bodercolor is giving this error. Please help me.

Nick

Hi forum…

I am working on an application that uses PDF4NET v. 4.1.0.0 to generate a consolidated PDF using multiple child PDF files. We have encountered a problem with this tool: sometimes it will not render one of the child files during the consolidated PDF generation. The child file generates the following message in a pop-up when going to that page:
There was a problem reading this document (20).

The other documents in this child file render properly, as do all the other children files. The problem child file renders properly when it is viewed by itself..

This is not an isolated problem, either. It has occurred multiple times (at least 3).

Is this a known problem? Does the tool have to use certain PDF files, such as ones created with particular versions of acrobat? We are using 4.1.0 currently, would upgrading to 4.1.3 fix this issue?

Hi there,

Thank you for submitting your query on the PDF4NET Forum here at ComponentSource.

I run this query with one of the authors of O2S PDF4NET and they sent this information for you:

====

This problem can appear because of multiple causes, we need to see the file before having an exact answer.
You can also try the latest version 4.2.1 to see if the problem is fixed. If not, please send us the child PDF file that is not merged correctly and we’ll investigate it.

PDF4NET problem veeramanig [MN, USA] 20-Jan-2011 07:05:39

Im using O2S PDF4NET (trial version) and facing some problem when we search and extract the text from the pdf (using O2S.Components.PDF4NET.dll) as mentioned below

1. Words in Capital letters are splitting as two words (ex: word “APPLICANT” extracted from pdf as “A” and “PPLICANT”)
2. Words in bold letters are splitting as two words (ex: “Borrower” extracted from pdf as “Borr” and “ower”)
3. Space (“ “) was omitted while searching a text in pdf (ex: "Important Information for Refinancings of Loans" text searched as “ImportantInformationforRefinancingsofLoans”)

Hello there,

Thank you for submitting your query here on the PDF4NET Forums at ComponentSource. I run your query with O2 Solutions and they sent the below information for you:

===
#1 & #2 – the problem is that the words you see on the page are not drawn as full words in the PDF page. They are drawn as separate string objects so PDF4NET does not know whether they are separate words or not.
#3 – the text does not contain actually space characters, the words are placed on the page at fixed positions so visually you have a page, but the page content does not include the space character. We’re working to improve the text extraction features in future versions of PDF4NET so these visual spaces are recognized and transformed into space characters.

I hope it helps,

PDF4NET - problem with SavePage() on accented chrs alastair.mutch [United Kingdom] 15-Nov-2010 12:03:38

Hi,
We have a problem with PDF4NET that is still present in the latest 4.1.3 version. George Smith emailed you about this in September and again at the end of October but got no reply. We are heading for a software release but this issue looks likely to throw us off schedule for all but the English releases.

Basically he is using the new .SavePage() method to force the PDF to be saved after each page. The created PDF is missing all of the accented characters in non-english languages. Using the .Save() method works OK but the PDF is too big for this to work in our application due to the resulting memory usage during generation.

We have a corporate license for v4.

Let me know if you want us to email you the example program again - this is the O2S example with minor modifications to use .SavePage() and clearly shows the problem.

Thanks,

How to make the Watermark non-editable pvarma [India] 12-Nov-2010 14:00:03

Hi,
I'm using the PDF4Net library to apply watermark to existing PDF files. However, these watermarks can be deleted if the user opens in a PDF Editor. I tried calling the FlattenFormFields() method on the PDFForm object before saving, but it still does not make the watermark non-editable. What can I do to address this issue?

RE: How to make the Watermark non-editable Adrian Marin (O2 Solutions) 15-Nov-2010 12:21:34

Hello Prabin,

How do you draw the watermark on document's pages? The FlattenFormFields method has effect only on form fields. The watermarks, like any other graphics on the page, can be edited with a PDF editor like Adobe Acrobat. You can try to encrypt the document and specify in the document permissions that document editing is disabled.

We have functionality within our application where we have added a button (via the PDF4NET product) to a a PDF page. This button performs a PDFSubmitFormAction which submits the aspx page. By adding the button to the PDF page and submitting the aspx page, we are able to capture and save all of the values in the PDF forms controls which have been prepopulated by our application and/or edited by the user. This functionality has always worked fine until the introduction of IE8 into the mix. With IE8 (and this seems to be regarding of whether the applicaiton is Win7 or XP), the page essentially freezes when attempting to reload after the submit.

The application always runs in IE. It always runs as a trusted site, so we can adjust IE settings as necessary to fix this. We have tried changing numerous IE settings but nothing has worked to date. Also, I've rules out anti-virus software because we have the same software running on workstations with IE7 and IE8 and the only workstations that have an issue are the ones with IE8 installed.

Has anybody run into this kind of problem, either with IE8 or with PDF4NET. Any suggestions?

Thanks

RE: PDF4NET Adrian Marin (O2 Solutions) 21-Oct-2010 14:37:13

Hello Tom,

This seems to be a problem with the Adobe PDF plugin for Internet Explorer. I suggest to put a breakpoint in the load event of the page that handles the form submission. If the page is not reached when clicking the submit button, then it is a problem with the PDF plugin, because at that moment only the PDF plugin has control over the PDF file. If the page is reached, then the data has been submitted with success and you can run through the code step by step to see if the page hangs in a PDF4NET call or it hangs somewhere else.
I hope this will help.

Hi Adrian,

I had already done what you suggested. In fact the page is successfully submitted. I am able to run completely throught the code successfully. The page hangs after all the code has completed and the page is attempting to re-display in IE. At that point, it hangs. It will eventually display completely, but it can take several minutes. (versus a few seconds during the initial display) If you check the view source of the page as it's attempting to reload, you can observer that it is only partially reloaded. One can observe some of the java script as it loads into the page. It hangs well before it is even attempting to redisplay the PDF form. It really seems to me that something in IE is preventling the reload.

Thanks in advance for any other suggestions that you might have.

PDF4NET - Printing jacques.victor [South Africa] 10-Sep-2010 07:50:37

Hi all,

I'm creating a pdf from a crystal report which has tables and borders in it, while making use of PDF4NET. Upon printing the pdf,of the tables' borders don't appear (some do).

The only way I've figured out to 'resolve' this issue is by setting the printers properties to 'print background images'. Needless to say this isn't a preferred solution for my company as we're sending out client statements via email which often are printed by the clients themselves.

Is there a way to 'force' the background to be printed or alternatively eliminate the background by flattening any potential layers in the pdf? I've been looking in the help files and searching online for 2 days and can't find a solution.

To give you an idea as to what is additionally being done to the pdf:

1.) I add page numbering
2) Watermarking (text with 50% transparency) on canvas
3) Add company logos
4) OMR markings (images) for internal printing company
5) Merging pdf's - Appending additional pdf's to customer statement

I would appreciate any advice you could give.

====

There is nothing PDF4NET can do here. The problem appears when the PDF file is created by printing it to a PDF printer. At that moment the PDF file is created without background, so PDF4NET cannot do anything.
The solution would be that your customer creates the reports in other ways so the images are not seen as background and they are printed without additional settings.

PDF4NET odd behaviour chris.thomas [United Kingdom] 18-Jan-2007 12:03:13

Hi there!

I'm creating several PDFPages in sequence, drawing text lines and some graphics, and saving it to disk. When viewing the pdf in acrobat, on some pages the text appears to be 'bold' and others it appears normal. It seems to be happening on pages where I'm drawing graphics (eg, I'm drawing graphics with page.Canvas.DrawImage on pages 1, 3, 4, and 5, and the text always appears heavy, and no graphics on pages 2 and 6, so the text always appears normal).

When the document is printed, there doesn't seem to be any noticable difference in the font weight, with all text appearing properly, in the normal font weight that I specified.

Is there anything I should be doing differently to prevent my users (and boss!) from thinking that some pages are in bold type? Has anyone else noticed this problem?

Responde

RE: RE: RE: PDF4NET odd... Adrian Marin [Romania] 13-Jun-2007 21:19:54

A common cause of this problem, the text appearing to be bold, is because both the pen and the brush are used to draw the text. The pen is used to stroke the text outline and this gives the bold appearance. Just use null (Nothing in VB.NET) for the pen parameter in DrawText/DrawTextBox method and the text will be displayed fine. If this does not solve your problem, please send an email to techsupport@o2sol.com with a sample PDF file that shows the problem you reported and we'll investigate it.
