How to display multiple .tif in C#? - c#

Is there any simple way to open and display multipage .tif files? I want to write a simple winForm application to open multiple page .tif file and scrolling around these pages? I want to add next and previous buttons to my project to scroll around them. Any suggestions or examples?

Try the free DotImage Photo SDK by Atalasoft. Though it is not open source, it is free and a very good choice for viewing images.
Meanwhile I will have a look if AForge.Net and EmguCV can open Multipage TIFF images and let you know. These frameworks are open source and include very powerful SDKs for image processing.

I know an SDK named leadtools that has the ability to load and display multipage TIF files using .NET. For a sample code, see the following link:

PDF First page image preview in DIV on website

In my system, there are multiple PDFs listed in the website. I need to show the preview image of 1st page of all the PDFs.
There are two previews which I want to display -
One small preview
One big preview on mouse hover
What I am doing now?
We are taking help few third party preview generators. Which is used to create JPEG image and using those images in the website for previews.
What I tried differently?
I used EvoPDFtoHTML tool to use HTML instead of images directly but for many files the generated HTML is not appropriate.
Also, These both process is taking a lot of time and making website
slow in response.
I would like to know that is there any better way to achieve this?
Image attached below for better understandings -
An approach that is worth exploring
Parse the PDF and extract the 1st page.You may use command line tools like : PDFtk, Ghostscript, or Implement your own class to parse out the first page in C#
Then use Google doc viewer and embed an iframe to point to PDF
Example of PDFtk:
pdftk input.pdf cat 1 output page-1-of-input.pdf
Example of GhostScript:
gs -o page-1-of-input.pdf -sDEVICE=pdfwrite -dPDFLastPage=1 input.pdf

You can also look at Fahims answer for the C# snippet that he tried

Extracting the first page of multiple PDFs & saving them as Image

I have about 400 ebooks, all in PDF format, and my task is to extract the cover from every one of them (which is the first page of every PDF) and export them all as separate image (PNG or JPEG) files
So I will end up with 400 ebooks and 400 images of their covers.
I have Windows
Any advice greatly appreciated.
Use ghostscript to render tiff or jpg from the pdf. You have fine grained control over the result.
If this is a commercial application, you need a commercial license. If you use the application commercially, but inside your organisation, you are allowed to use the GPLed version of ghostscript.
Ghostscript can be found here. The PDF interpreter in many opensource packages relies on the gs PDF interpreter. Imagemagick for example, requires ghostscript libraries.
Download GS here: http://ghostscript.com/download/gsdnld.html
Use C# Process class to execute Ghostscript, there is a SO topic on this here How to run a C# console application with the console hidden
The commandline for tiff will be:
D:\gs\gs9.20>bin\gswin64c.exe -sOutputFile=d:\some%02d.tiff -dBATCH -dNOPAUSE -sDEVICE=tiff24nc -sCompression=lzw -r150 -sPageList=1 d:\PDFReference.pdf
This will create one some01.tiff file on d:\ in 150dpi resolution.
The following thread is suitable for your request. converting pdf file to an jpeg image
One solution is to use a third party library. ImageMagick is a very popular, freely available too. You can get a .NET wrapper for it here. The original ImageMagick download page is here.

If you use this process to convert a PDF to tiff, you can use this class to retrieve the bitmap from tiff.

Best way to display pdf document in asp.net application

I'm looking for the best way to display pdf document on a website. Surely I need to convert it to jpeg or gif for the browser to handle it. I read few posts but most refer to GhostScript and its pdf2image. But that solution calls for starting a process that would save a copy of pdf doc to the file system and then would have to be loaded back into memory for displaying. Frankly I find it a bit clumsy. For those of you who have done it, what library you used and if you could attach a link to some examples, I'd greatly appreciate it.
I'm developick a web application that helps manage manufacturing process and is accessed fron android tablets. Company has a stockpile of documentation in pdf files that is to be delivered to production managers. I'd love the solution to be akin Crystal Report Viewer contron but I I understand that I have to stick to pdf to image conversion. Please give me some advise here.
My advice is don't over think this.
You can simply add a link to the PDF file, which will open on a new tab.
You can take a look at http://mozilla.github.io/pdf.js/ which will allow you to render a PDF on the client side.
Or if you decide to go with a Ghostscript, you can take a look at http://ghostscriptnet.codeplex.com
By all accounts the PDF Focus .NET library seems to be the best solution. A wrd of advice is to add a cleanup method to the page unload to delete all temporary files that were used to feed source into image controls when displaying pictures on a website.

Wanted: ASP.NET control to view/print PDF, TIFF, possibly more?

I'm looking for an asp.NET control that will allow for viewing and printing of a pdf and TIFF within a web form. I'm willing to use more than 1 control if needed (1 control for pdf, 1 for Tiff, show and hide based on file extension), but I have not been able to find a good Tiff viewer.
Files are stored on our LAN in a shared folder, and this application is an intranet site.
Open source / free licensing preferred, but I'm willing to look at paid options as well.
http://www.alternatiff.com/ is one of the viewers that I've seen used for this type of viewing of tiffs.
You can get a free licence of ABCPDF (provided you link back to their site) which will do the conversion from TIFF to PDF for you as per #Chris Lively 's suggestion.
It'll also do conversion from PDF to TIFF if you decide to do things backwards.
It makes sense to present the content in a common format. If you wanted to you can embed the PDF in the browser to create the 'seamless' experience you're looking for using something like PDFObject.
As #BenCr says though, PDF is a really common format and the tools already exist to open and work with them, so introducing new ways to perform existing tasks could actually end up complicating matters unnecessarily.
I'm in total agreement with #BenCr on this.
Viewing PDFs is an extremely common thing to do. This isn't a "technical" issue by any stretch.
It sounds like you have some type of faxing solution in place that is creating these documents. Most likely multi-page TIFF and PDFs.
If this is the case you might want to just convert the TIFFs to PDFs to begin with and run everything through Adobe's pdf reader. Every online fax solution does this.
You could try http://issuu.com/ and they appear to have a API too if you want to go that deep.
We used the the Seadragon control to do this. I think it was an overkill and we should have just rolled our own -- would have been cheaper than integrating it. TIFFs and PDFs are converted to PNG on the server side. I don't think you can do better than that, especially with PDFs (assuming you don't want to use Acrobat Reader to display them). Convert PDFs to PNG using Xpdf/Poppler.
How about using Google Docs Viewer?
EDIT: Probably not working, since the viewer has to read the document from your URL; when it's on the Intranet, this won't work.
If you can mess about with mime types -- mainly by making the .tiff files expose an application/pdf mimetype -- you should be able to get acrobat to open TIFF files directly by effectively fooling the browser to open TIFF files with acrobat. Then all you need is a trusty old iframe to get you familiar UI with print buttons.

C# PDF Control & Library

I'm looking for a way to display a PDF (similar to a picture box), in a Windows Form. After that I need to be able to create a PDF. What's the best library for the job for creating the PDF (from simple text)? I've taken a look at several and I'm not sure which one is the best. Preferably open source. As for the control, I tried the COM object Adobe provides... I can't seem to get it working. At all. I've tried loading several files, there are no errors. It simply fails to load.
PDF Sharp, Sharp PDF and iTextSharp are excellent. They are all OpenSource.
To answer your question about getting the PDF to render, you could use a WebBrowser Control on your form as long as the client workstation has Adobe Reader installed. The browser will automatically pick up the MIME type and load the in-browser Adobe Reader.
For rendering, I echo Will Marcouiller and SLaks. We have had good success with PDFSharp.
For creating pdf's iTextSharp is very good, and it's free too.
I worked with SharpPDF and it did great job. And it's open source.
