c# - Using portable imagemagick convert program

Question

How do I pass image filepaths to convert.exe, given I know all the file paths?

ImageMagick is NOT installed, but just in my project folder. I don't think I'm supposed to pass the image filepaths through a cmd prompt.

Here is my current attempt. I get no errors from it -- but a cmd prompt pops up quickly and disappears quickly -- I've printed the screen when it's up and it's saying something about userparams... which apparently has to do with ImageMagick somehow.

When I run the same command directly in a command prompt without Unity (which is what I'm using to run the code below), I get the following:

Anyway, as stated, I'm not sure what I'm doing wrong. Here is the code in the software that's causing the same problem:

    string currDir = System.Environment.CurrentDirectory;
    string convertPath = currDir + @"ImageMagickconvert.exe";
    string convertedDir = currDir + @"ConvertedPDFs";
    string pdfFolder = currDir + @"PDFs";
    string fileName = "Appointment";
    //System.IO.Directory.CreateDirectory(currDir + @"" + convertedDirName);
    string argumentForImageMagick;


    argumentForImageMagick = pdfFolder + fileName + ".pdf" + " " + convertedDir + fileName + ".png";
    ProcessStartInfo info = new ProcessStartInfo {Arguments = argumentForImageMagick , FileName = convertPath};
    System.Diagnostics.Process.Start(info).WaitForExit();

When I print the argument and filepath for the ProcessStartInfo instance, I get

F:ImageMagickTestPDFsAppointment.pdf
F:ImageMagickTestConvertedPDFsAppointment.png

for the argument, and

F:ImageMagickTestImageMagickconvert.exe

for the filepath.

What is going wrong?

Answer 1

Ok, I've figured out part of the problem -- I had to have Ghostscript installed. This doesn't work for me, as I can't install any software on the host computer...but I guess now I know what was wrong! Thanks.

My next question is basically whether I can run ghostscript without installing it on a host computer...
