Converting a multiple-page PDF to a single image

Question

I\'m attempting to convert a PDF into a single image using GhostScript.

Only the first page is converted, while my intention is to generate a horrendously tall PNG/

Answer 1

You will most likely need to render the single pages using GS and then combine them to a single PNG/JPG using some scripting language.

Answer 2

You can check this open source project on Code Project

http://www.codeproject.com/KB/cs/GhostScriptUseWithCSharp.aspx

That show how to call Ghostscript and how to pass the parameters

Answer 3

After converting multi-page PDF to images (PNG, JPEG, TIFF, etc.) using GS, you'll need to take one step further to merge the output images into a multi-page TIFF image.

Take a look at the source code of VietOCR.NET, which has the functionality but does it in two separate steps. You can modify it to call the two functions back to back.

Answer 4

You can look at PDF to Image

Answer 5

Did you have a look at ImageMagick? This free library might have an option to create a single image from a PDF (It actually uses Ghostscript but adds a lot of graphical editing capabilities such as merging images).
