Running console commands to convert with ImageMagick from within Unity 3d - windows

Question

Folks!
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:
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);
}
}
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
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?
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:
strCmdText= currDir + #"\PDFs\Appointment.pdf" + " " + currDir + #"\" + convertedDirName + #"\" + "Appointment.png";
System.Diagnostics.Process.Start(currDir + #"\ImageMagick\convert.exe",strCmdText);

Answer 1

Try using some other commands (like dir) to figure out where you are in the filesystem and what is going wrong.
Also remember that if you are using the portable version and it is not in your path, you will have to execute it from the same directory as it is in.
