This gives you the ability to preview the first page of a PDF file on your web page. 8 | 9 | ## Installation using Nuget 10 | 11 | Install-Package ImageProcessor.Plugins.PDF 12 | 13 | ## GhostScript 14 | We use [GhostScript.Net](https://github.com/jhabjan/Ghostscript.NET) as a managed wrapper for [GhostScript](https://ghostscript.com/). 15 | The good thing is, you don't need to install ghostscript on your machine. 16 | You can just copy (one or both) `gsdll32.dll` and `gsdll64.dll` in the /bin directory. 17 | **These files are not provided in this packages and must be added manually.** 18 | 19 | I read that Ghostscript does not handle requests from multiple processes. 20 | When running on a webserver, be sure to run the website in his own applicationpool. 21 | 22 | ## Configuration 23 | Just add `/myfile.pdf?format=jpg&width=500` to get the first page as an image. 24 | 25 | ## running locally on IIS express 26 | If you run locally, and you have the 64 bit version of ghostscript installed, 27 | don't forget to [activate 64 bit of IIS express](https://visualstudio.uservoice.com/forums/121579-visual-studio-ide/suggestions/3254745-allow-for-iis-express-64-bit-to-run-from-visual-st). 28 | 29 | 30 | -------------------------------------------------------------------------------- /ImageProcessor.Plugins.Pdf.csproj: -------------------------------------------------------------------------------- 1 | 2 | 3 | net45;net46;net47 4 | ImageProcessor.Plugins.Pdf 5 | ImageProcessor.Plugins.Pdf 6 | A plugin for ImageProcessor adding PDF as a recognized input format.
