Recently the company arranged to have a mission: to deliver a required DLL, to achieve [PDF] into a picture, the best results are able to master all the source code, it is not only the delivery of third-party DLL. Studied six working days + 1 + day weekend from work every night 9:00, take a stroll various domestic and international forums, or did not make it out of the entire source code, but found a lot of useful tools and other tools for everyone to share in this .
1. [iTextSharp.dll], C # open source PDF processing tool that can operate in any PDF, and can extract PDF text and pictures, but you can not directly convert PDF into picture.

more than two tools are open source C # PDF documents can be a good deal, but do not meet my request directly converted into PDF IMAGE.
[3] ImageMagick, C language open-source PDF processing tool that can convert PDF to realize the picture, because it is a C # project, so the C language I did not test too much.

4. [Acrobat.dll], the interface provided by Adobe official, can achieve PDF transfer pictures.
This method requires the installation of Adobe Acrobat X Pro, copy the files from the installation Acrobat.dll can, because the file is too large to be more than 500M, not available for download.

this program program is my last resort, after all, is the interface provided by Adobe official, the conversion efficiency of other DLL to be much faster than, and it should be more reliable number.
5. Free Tool: [] Ghostscript can be achieved PDF transfer pictures, looks like a lot of people online will adopt this approach, but I do not think it useful.

last posted all the code and dll's address, in order to avoid Children's shoes one by one in trouble, but the corresponding branch a little higher, after all, I downloaded this stuff with me 100 points, ah, let me know the importance of the points.

Finally, I think the best use [or] Acrobat.dll because the most efficient, most stable, at the same time five PDF conversion can be successful, but with a third-party DLL will appear the phenomenon of collapse.
Secondly Recommended [O2S.Components.PDFRender4NET.dll], because the use of this code is the most simple, the most convenient to use, and the efficiency is not bad, there is no watermark, but a crack, we all pondered this.
Above is my research it, if you have any good advice welcome give me a message, you can also add my QQ: 605494869 or micro-blog: http: //weibo.com/605494869 exchange.
