title: Running console commands to convert with ImageMagick from within Unity 3d
body: <p>Folks!</p>
  
  <p>So, I'm attempting to convert a PDF to a .png, as the title implies. I'm using the software package ImageMagick. I want to use this package to convert pdfs to pngs on-the-fly from a Unity 3d project -- so that the application can display the PDFs as .png textures in-game when it needs, but still preserves them as PDFs for smaller file sizes. I'm not quite sure what I've done wrong, here -- but when I run it in Unity, all I get is an open cmd prompt without my command in it. Is there something obvious that I'm missing, here? Here's the code:</p>
  
  <pre><code>using UnityEngine;
  using System.Collections;
  using System.IO;
  using System.Reflection;
  using System.Security.Policy;
  
  public class CommandLineTest : MonoBehaviour {
  
      // Use this for initialization
      void Start () {
          string convertedDirName = "ConvertedPDFs";
          string currDir = System.Environment.CurrentDirectory;
          System.IO.Directory.CreateDirectory(currDir + @"\" + convertedDirName);
  
          string strCmdText;
      strCmdText= @"/c " + currDir + @"\ImageMagick\convert.exe " + currDir + @"\PDFs\Appointment.pdf " + currDir + @"\" + convertedDirName + @"\" + "Appointment.png";
          System.Diagnostics.Process.Start("CMD.exe",strCmdText);
          //ImageMagick
          print(strCmdText);
      }
  
  }
  </code></pre>
  
  <p>When the print statement at the end runs, it prints the following string: c/ convert /c F:\Documents and Settings\Administrator\Desktop\ImageMagickTest\ImageMagick\convert.exe F:\Documents and Settings\Administrator\Desktop\ImageMagickTest\PDFs\Appointment.pdf F:\Documents and Settings\Administrator\Desktop\ImageMagickTest\ConvertedPDFs\Appointment.png</p>
  
  <p>Does anything appear obviously wrong, to you? I should mention that ImageMagick's convert application is not actually "installed" on my system -- I'm just using the "portable" version and have thrown it in my project folder. So I was hoping that the "convert" command line would still work. Does this mean that I can't access it with a dos prompt? If I can't, then how do I pass an image to the "convert" program in imagemagick using, provided I know that it's going to be in my project's folder?</p>
  
  <p>EDIT: Some people have suggested that I access convert.exe instead of cmd.exe, and to attempt to just feed the image paths to it that way. So here is the second way I'm trying it: </p>
  
  <pre><code>strCmdText= currDir + @"\PDFs\Appointment.pdf" + " " + currDir + @"\" + convertedDirName + @"\" + "Appointment.png";
          System.Diagnostics.Process.Start(currDir + @"\ImageMagick\convert.exe",strCmdText);
  </code></pre>
