Create thumbnails using MigraDoc or PDFsharp - pdf

We have a need to take a single PDF file, break it into separate page thumbnails, and based on user input, put together selected pages into a new PDF document.
Can someone show a quick example of how to take a single PDF document and generate a thumbnail preview of each page using either MigraDoc or PDFsharp?

Those who read FAQ lists will know that neither PDFsharp nor MigraDoc can render PDF files.
To create thumbnails from PDF pages you have to render them.
You'll need a different library to create thumbnails.

Using PDFBox or something else, is it possible to know if a pdf contains no scanned pages?

I'm looking for a solution to detect if a pdf document contains some non-searchable text, I'm thinking about a scenario where a multi-page pdf contains some plain text pages, with or without images it doesn't matter, and one or some pages containing non-searchable texts.
So I would like a method returning true/false which is able to detect if a pdf contains some non-searchable text (or viceversa), in your opinion is it possible with PDFBox or something else?
Thx

Want to add content of pdf page to another pdf

I have two pdfs both with limited data i.e. Single page. I want to merge the data of one pdf into another pdf but on the single page (It should not create the other page to append the external data). Is there any way to do this using pdfbox or pdfclown ?

Export PDF Page contents to individual pages

I have a pdf document which contains more than one page within each page.
The original document is only 2 pages - size A4, but has multiple pages on each of the 2 pages.
I need to export each of these "pages within each page" to an individual pdf page.
I have tried increasing the zoom of the pages and printing from there, but it prints incorrectly.
What could I do within Adobe reader or similar program to export each of these pages each as their own pdf page ?
Link to PDF
Within Acrobat reader, you could make a clever use of custom poster printing (possibly to print as a new PDF):

Otherwise you can do any of these:
Splitting single page into two pages with ghostscript
Alternatively you could use other tools such as Inkscape to do the splitting.

How to clip and concatenate a page region in multiple pdf files with one page each?

I have a lot of pdf files each one with an image inside. I want to clip a rectangular region in each of these files and concatenate them into a single pdf file. Is it possible with ghostscript or similar?
I'll have a go at this. Try Briss if you want to crop rectangular regions in pdf files. It's free and cross-platform GUI.
If you have multiple pdf files you can concatenate/merge them first online using http://www.pdfmerge.com/ Then use Briss to crop the images out into a new pdf file. Or vice-versa depending on the location of your images inside the pdf files.
After you fire up Briss, load the merged pdf file containing the images. When you're asked if you want to exlude anything, just click "cancel" if you want to include all pages.
If your file has many pages, similar pages may be overlapping each other so you can draw a rectangle over the region you want to crop. Click Action -> Preview for previewing the output. Click Action -> Crop PDF to finalize your output pdf file. Cheers.

Get thumbnail image of PDF using ASP.NET?

I have a system where users can upload PDF documents. Rather than displaying the link to these PDFs as a title link, or a PDF icon link, I would like it to be a thumbnail of the first page of the PDF document.
How can I get a thumbnail image of the first (or any specified) page of a PDF document, using ASP.NET 3.5?
Here is a free component to display PDF thumbnails in asp.net: http://www.tallcomponents.com/pdfthumbnail-versions.aspx
GhostScript is another option.
There are no built in PDF capabilities in the BCL.
You will need to use a PDF library that allows you to output images. Use it to render the first page as a thumbnail.
Here is one article on code project to do this (using acrobat and COM interop), here a thread on MSDN forums .
