Problem invoking Runtime.exec with ImageMagick

Hello everybody, 

in my Java application, I use ImageMagick's "identify" command line tool to get various properties of image files. 

However, in order to get the properties of EPS files, ImageMagick's "identify" uses ghostscript (calls gs), which I have downloaded and installed separately. 

"identify" also works nicely and seemlessly with the command line on EPS files exactly the same way it would work with JPEGs etc. 

However, Java's Runtime.exec method seems to require an extra step for dealing with identify's call to gs. The following code snippet: 

                try {

   

                    Process process = Runtime.getRuntime().exec(invocationString);

   

                    process.getInputStream().read(myBytes);

   

                    results = new String (myBytes);

   

                    System.out.println("##### "+ results );

   

                } catch (Exception exception) {

   

                }

produces my desired result string as long as I work with non-EPS files. If I use EPS files and identify calls "gs", my result string is empty and I get nothing back. 

Is there anything I have to watch out for? 

Thanks in advance for any hints...

Ralph
