Get Print DPI Resolution?

  • June 1, 2019

In Windows File explorer I can right click on an image file and click on properties. In the Properties window details tab in the image section see the Images Print resolution setting.  Is there any way with javascript  to get this Print DPI resolution without opening the image file in Photoshop?

Correct answer SuperMerlin
#target photoshop;
main();
function main(){
var file = File.openDialog("Please select JPG file.","JPG File:*.jpg");
if (file == null) return;
if ( !ExternalObject.AdobeXMPScript ) ExternalObject.AdobeXMPScript = new ExternalObject('lib:AdobeXMPScript');
        var xmpf = new XMPFile( File(file).fsName, XMPConst.UNKNOWN, XMPConst.OPEN_FOR_READ );
        var xmp = xmpf.getXMP();
        if(xmp.doesPropertyExist(XMPConst.NS_TIFF, "XResolution")){
        var res = xmp.getProperty(XMPConst.NS_TIFF, "XResolution");
        res = res.toString().split("/");
        alert(res[0]/res[1]);
        }else{
            alert("No resolution, default 72ppi");
            }
};
