I have an msword document that consists of some pages, i need convert only the first page to image and save it. Each page can consist of images, tables, text, etc. But i can't use clipboard buffer or any commercial software.
May be anybody know some other ways ?
You can turn on the "Generate thumbnail for Document" option and word will generate an image for you (that Windows 7 uses to show the large icon view of the document.
In word 2010, click File-Info
then the Properties Drop down
Then Advanced properties
Then Summary tab
and finally SHOW PREVIEW PICTURE
And what's worse, you can't automate it! Ugh, Something about a security risk.
When you do that, there will be an extra WMF file embedded within the DOCX that you can extract.
Print your first page to the Microsoft Office Document Image Writer.
It will give you a TIFF image.
EDIT
Alternatively, print to the Microsoft XPS Document Writer and then convert XPS to an image.

Viewing PDF in Windows forms using C# [closed]
(5 answers)
Closed 7 years ago.
I am trying to display a PDF in a winform using C# .net
I have included the iTextSharp Library, and successfully opened the PDF file, however I get a byte[] back from iTextView
PdfReader reader = new PdfReader(GetURI("test.pdf"));
reader.getPageN(1); //returns byte array
I can't find much documentation on this library, and I was wondering how I would get the PDF on the actual form, be it in a picture box or a webview. How do I display the pages of the PDF?
EDIT:
I Don't want to open it in a third party reader
I don't want dependencies on adobe reader
I want to focus on a solution with iTextSharp or something similar, as I need to secure the PDF, encrypt it and eventually alter it.
You can easily display PDF in WebBrowser control. Add a webBrowser control to your Winform. Add the following method to your form.
private void RenderPdf(string filePath)
{
if (!string.IsNullOrWhiteSpace(filePath))
{
webBrowser1.Navigate(#filePath);
}
}
Call this method by passing PDF file path,
RenderPdf(#"PDF path");
ITextSharp allows you to create and manipulate pdf's, but does not provide any rendering options like Bradley Smith said in a comment above
I did something similar a long time ago and what I ended up doing was using Ghostscript to generate a tiff image from my pdf and displaying that instead. Obviously that just displays an image so if you need to edit the pdf, this won't work for you.
Ghostscript is command line only so I think you have to run it something like this:
Process.Start(#"c:\gs\gs.exe",
String.Format("-o {0} -sDEVICE=tiffg4 -dFirstPage={1} -dLastPage={2} {3}", "tiffPages.tif", fromPage, toPage, "inputfile.pdf"));
This question is a copy of this
The answer I found:
i think the easiest way is to use the Adobe PDF reader COM Component
right click on your toolbox & select "Choose Items" Select the "COM
Components" tab Select "Adobe PDF Reader"
then click ok Drag & Drop
the control on your form & modify the "src" Property to the PDF files
you want to read i hope this helps
what about using a viewer control from any vendor? Found it on the first page in google: viewer control for windows forms
If a commercial library is an option, try Amyuni PDF Creator .Net. You will be able to display your PDF document in a form, modify the document or encrypt it. You will not need to rely on any other program to be installed, or any external processes.
As other answers and comments have mentioned, iText is not designed for displaying PDF documents.
Disclaimer: I work for Amyuni Technologies.
I am developing a C# WinForms application, and I would like to be able to "preview" various document types within it. That is, when a user selects a filename from a list, it shows below, within the same form, a preview of the selected file. It's a lot like they way Outlook allows you to preview a selected message without double-clicking.
Is there any way to take just a filename and create a control dynamically within my WinForms application that shows the contents of that file?
If you want to provide a preview/readonly version of the file types, an idea might be to implement PDF viewing first, this primarily involves converting PDF pages to images and then creating a view for those. Once you have that done (using GhostScript or other commercial components) you can then work on converting other formats to PDF, and use the PDF viewing option, you can probably do most office documents through word automation and text based files could be displayed directly (possibly using a rich text editor for formatted text)

Using WKHtmlToPDF to generate PDFs for my company's web-based mapping service.
Essentially, I take a template HTML file, inject an image into a div, save the HTML to disk and use WKHtmlToPDF to render to PDF.
Now, on most templates it works a treat. On one particular one though, where the image should be (int the pdf) is a grey area. HOWEVER, if I right click on the grey area, and select "Save Image As...", the saved image is correct.
Linked are the created PDF and the HTML on which it is based. Help required most urgently, and hints appreciated.
Zip File Containing HTML and PDF
I was having an issue where a particular image was not being printed to the PDF. Other images on the same page were. The src of the missing image is from a CDN, but had no extension, i.e. src="\\path/to/image?param". Using the aforementioned -n switch (disable Javascript), the image shows up in the resulting PDF. Thanks Jordaan.
Don't know WHY this worked, but adding the "--disable-smart-shrinking" option, and/or removing the "-n"(Disable Javascript) option, fixed it.
Hi All,
I am creating a PDF document using ITEXTSHARP. I need to add some content to PDF toolbar while creating the PDF document. How can i achieve this using C#. Please see the attached image for reference.
Thanks in advance.
iTextSharp is used to generate PDF files, not modifying the PDF viewer. If you need to modify toolbars and stuff like this in Adobe Reader this definitely is not something that you could achieve with iTextSharp.
eh...
Ok so how to do it.
Make template in Word.
eg of Word
Name <FirstName>
Surname <LastName>
Job <JobType>
Salary <Salary>
When generating:
Open word and replace and other marks
Then makepdf (pdfcreator for example)
Edit:
Okay Ill show u schema, no ready code cuz little busy
1) Create word template and
store it in safe place. 2) Copy
template to temp folder 3) Open in
programicaly in C# and replace
"" with ur data
.Replace('', 'Voon') 4)
Programiticaly print to PDF and save
it.
Only a plugin can modify the acrobat/reader toolbar. There might be C# bindings for the acrobat API these days, but I wouldn't count on it.
PS: You can make Acrobat plugins for free. To "Reader Enable" a plugin requires Adobe's direct intervention, and $$$. They sign a version of the plugin, and only that signed version will run in Reader.
Your best bet is to go looking for some third-party PDF viewer. I still wouldn't count on this feature being available, but it's better odds than "0".
I have a 2-page PDF that I want to overlay information on (think of a form that someone manually fills out) using a C#/.NET Windows application. After this form is generated, it will need to be previewed and printed (exported into a graphic or PDF is nice, but not a requirement).
At first glance, I'm thinking of two ways to do this:
Use a PDF manipulator like iTextSharp, take a copy of the blank PDF form, and add text to the PDF. Then, launch Adobe Reader to do a print or preview.
Convert the PDF into a graphic, and put the graphic into a C# Report. Then, overlay text fields onto the report, and use a .NET ReportViewer control to preview and print the report.
The text does not need to be searchable or copyable or have any of the cool things that PDF gives me, so I'm leaning towards the second option. Am I missing anything, or is there something I'm not thinking of? Thanks in advance.
We use #1 extensively and it works perfectly. You shouldn't have any problems, it's rather easy (just need to make the fields writeable and use a FDF file and merge it with the PDF file). At least that's how we did it.
