emf to jpg conversion

Question

My objective is to convert emf,wmf file formats to other image file formats.

I included image4java jar and tried to convert my emf file to other formats like jpg,png.. using the following code:

import org.im4java.core.ConvertCmd;
import org.im4java.core.IMOperation;
import java.io.File;
public class im4java {
    public static void main(String arg[])
    {
        File input=new File("src/image.emf");
        File output=new File("src/output.jpg");
        convertemf2png(input,output);
    }
    public static void convertemf2png(File input,File output)
    {
        try{
        IMOperation img=new IMOperation();
        img.addImage();
        img.addImage();
        ConvertCmd convert=new ConvertCmd();
        convert.run(img,new Object[]{input,output});
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }
}

while i execute it, i got the error like

1. when i use simply convert.run(img,new Object[]{input,output}); i got

   java.lang.IllegalArgumentException: java.io.File is an unsupported image-type

Answer 1

You need to set the path to the ImageMagic executable - you are inadvertently calling a windows program named convert
