i am generating a report in vb.net using itextsharp. sometimes the entire report does not fit on one page and i need to know when itextsharp is adding a page to the document.
View 1 RepliesI have googled and searched and I am currently unable to work out how I can achieve this.I want to open an existing multipag pdf and append with text absolutely positioned on specific pages before outputting the appended pdfI am sure I need to use the a pdf stamper but I am a little confused and am not confident in readin c# examples
View 3 RepliesI am trying to integrate iTextSharp into an existing Document Imaging application that allows users to rotate individual pages that may have been scanned in at an incorrect angle (it happens more often than I would have thought).

I want to delete one or two PDF page and want to insert a blank pdf page using iTextSharp. is it possible using itextsharp?
For example, i want o delete the 25,26 th page of a pdf document, and want to insert a blank page there.
I'm using itextsharp with a aspmvc project to create PDF versions of some of my pages. I have a very basic parser which takes simple html (plus some style info supplied seperately) and creates a pdf. When my parser encounts a table it loops over rows then cells, creating a PdfPCell for each cell. It then loops over child elements of the cell adding them to the PdfPCell. It's pretty basic but it's worked for me so far.
The problem is that I now have a table one column of which contains a number of icons, indicating different status for the row. When these images get added then end up one above the other in the pdf, instead of next to each other.
I create the image with
Dim I As iTextSharp.text.Image = Image.GetInstance(HttpContext.Current.Server.MapPath(El.Attributes("src").InnerText))
I have tried
I.Alignment = Image.TEXTWRAP Or Image.ALIGN_LEFT Or Image.ALIGN_MIDDLE
and adding a text chunk afterwards containing a space but it doesn't help. The only suggestion I have seen is to use I.SetAbsolutePosition(). I'd rather avoid absolute position but am prepared to try it - except I can't work out how to find the current X position to use?
I have a program that parses INI files (yes yes, I know, but I'm stuck with using them, not my own request), and it downloads external images (if the INI contains the path) to the program and cache's them.
Recently, I've run into a snag with the system. Most of the images use Imageshack for storage, but one of them has suddenly 404'd, and whenever I set it to the picturebox to the downloaded image, I get an out of memory error rather quickly (and the file itself is 1kb).
I guess I need to implement a checking system offline to find out if the image is actually an image or just a '404' text...but is there a way to not have to implement this clientside, and have it be checked when I download it?

what is the height of a regular PDF page in pixels?
i heard it was something like this:
Dim pgSize As New iTextSharp.text.Rectangle(595, 792)
but i am adding an image that takes up maybe half the height, and even though pgSize looks like a full page and the image takes up only half of it, i am getting a height of like 619 for the image? i do not know if it is in the same units?
I am placing and image using this [code]It works perfectly however when my document is extended to second or third page.. it does not stays on the first page.. it stays on same position however moves to the last page
View 1 RepliesI have implemented tab control on an existing form by using form designer and copying button from an existing vb application. my goal is to run a piece of code when a button on a tab page is sellected. How do I go about implementing this? I can detect in the code which tab page was selected but not that the button on the page is sellected.
View 1 RepliesMy VB.NET code is supposed to execute third party Javascript code in an attempt to fill in and submit a form. This process consists of five steps, and I have been able to submit the form when all the steps are kept separate (i.e. behind 5 separate consecutive button clicks). Now, what I'd like to have is one button to handle all the five steps.
The problem is that the form originally only appears after calling "webbrowser.Navigate" command, which apparently modifies the page's HTML code. I seem to be unable to detect when Javascript has finished loading the new HTML in order to fill and submit the form. I have tried a timer control to wait for a certain HTML element ID to appear, but in vain. [URL]

What I need to do is query an iTextSharp AcroField to check if it is rotated, and if so capture the value of the rotation.So If I have the following field:
Dim af As iTextSharp.text.pdf.AcroFields = stamper.AcroFields

afi = af.GetFieldItem("fieldName")
What do I need to do to get the rotation (in degrees) of that specific field?

I am adding watermark text to PDFs in a class library I have created. The code I posted below works fine, however the watermark is sometimes difficult to read because it overlays with content on the PDF. How would I go about adding a white background color around the watermark text? I basically would like the watermark text to be surrounded inside a white rectangle the size of the text.

I'm working in .net 2005. I have a collection of points and I'm creating a polyline with them; however, I need to curve fit them so that they appear to be some what straighter.
If you look at my picture, you can see the blue dots represent the points and the red line is a represenation of how I'd like the final results to be. (Basically, I need to line to appear straighter and less jaggedy looking than it is now).
I didn't know if I should try to see if there's some plug-in for doing this or if vb.net has anything I could use to do this myself.

View 1 RepliesI have a program and wish to generalise its appearance at startup on different machines. This worked OK until I moved it onto a Windows 7 unit with a 22" screen. The front page covers less than 2/3 of the screen. I know I've asked the system for 'working area' but could not find a reference to the entire screen which other applications seem able to use. How can I catch up with them? The code is from VB in VS2005. Is this my limitation?
