How To Use

public class Test {
        public static void main(String[] args) {

            DiffSetting diffSetting = DiffSetting.getDefaultSetting();
            diffSetting.compSetting.ignoreDifferentTextStyle = true;

int res = XDiff.diff(control, test, reportDir, diffSetting);
        }
    }

Options:
      -config                            : Comparison configuration file path.

Example: java -jar xdiff.jar c:/config.properties c:/xdiff/control.pdf c:/xdiff/test.pdf c:/xdiff/report
    
For Postscript file comparion, xdiff.ncc need [GhostScript](https://www.ghostscript.com/download/gsdnld.html) installed in advance, xdiff.ncc will use it as a Postscript to PDF convertor. Set GS_Path in config.properties:
    
    GS_Path = C:/Program Files/gs/gs9.18/bin/gswin64c.exe
