Can anyone help an idiot (me) with a bit of javascript? Trying to write a script that identifies whether an image is portrait or landscape orientation then scales the image so that it is at a minimum 7016 x 9933 px (or 9933 x 7016 depending on orientation...)

I think I've got the basic logic of it right but I don't know a jot about js but think in order for this to work I need to have the five lines after each if(Orientation...) condition be a block statement but can I do this whilst having another condition inside of it? If anyone could explain it to me like I'm five I'd be greatly appreciative!



app.preferences.rulerUnits = Units.PIXELS;

var doc = activeDocument;

var Orientation = parseFloat(doc.height/doc.width);


if(Orientation>=1)

var doc = activeDocument;

var wFactorP = parseFloat(7016/doc.width)

var hFactorP = parseFloat(9933/doc.height);

if(wFactorP>hFactorP){doc.resizeImage(7016,undefined,undefined,ResampleMethod.BICUBIC)}

else{doc.resizeImage(undefined,9933,undefined,ResampleMethod.BICUBIC)}



if(Orientation<1)

var wFactorL = parseFloat(9933/doc.width)

var hFactorL = parseFloat(7016/doc.height);

if(wFactorL>hFactorL){doc.resizeImage(9933,undefined,undefined,ResampleMethod.BICUBIC)}

else{doc.resizeImage(undefined,7016,undefined,ResampleMethod.BICUBIC)}

I think this is what you're trying to do

app.preferences.rulerUnits = Units.PIXELS;
var doc = activeDocument;
var Orientation = parseFloat(doc.height / doc.width);

if (Orientation >= 1) {
    var wFactorP = parseFloat(7016 / doc.width);
    var hFactorP = parseFloat(9933 / doc.height);

    if (wFactorP > hFactorP) {
        doc.resizeImage(7016, undefined, undefined, ResampleMethod.BICUBIC);
    }
    else {
        doc.resizeImage(undefined, 9933, undefined, ResampleMethod.BICUBIC)
    }
}

else if (Orientation < 1) {
    var wFactorL = parseFloat(9933 / doc.width)
    var hFactorL = parseFloat(7016 / doc.height);

    if (wFactorL > hFactorL) {
        doc.resizeImage(9933, undefined, undefined, ResampleMethod.BICUBIC)
    }
    else {
        doc.resizeImage(undefined, 7016, undefined, ResampleMethod.BICUBIC)
    }
}
