im4java throws FileNotFoundException error
<p>I need to use ImageMagic in my java project.
I already installed ImageMagic-7.0.3 on Windows 10
(command line works fine)</p>

<p>Then, i added dependency to im4java in maven file. When i try to do some action like:</p>

<pre><code>public static void main(String[] args) {

String imPath="C:\\Program Files\\ImageMagick-7.0.3-Q16";
ConvertCmd cmd = new ConvertCmd();
cmd.setSearchPath(imPath);
IMOperation op = new IMOperation();
op.addImage("biuro.jpg");
op.negate();
op.addImage("biuro_new.jpg");


try {
    cmd.run(op);
} catch (IOException e) {
    e.printStackTrace();
} catch (InterruptedException e) {
    e.printStackTrace();
} catch (IM4JavaException e) {
    e.printStackTrace();
}

System.out.println("works");

}
</code></pre>

<p>i get following error</p>
