Add a black drop shadow to an image through InDesign JavaScript scripting

Question

I am an absolute beginner with JavaScript scripting for InDesign. I create an object like this:

var rectbox = doc.pages.item(0).rectangles.add({geometricBounds:[20,20,70,120]});
var image = rectbox.place(File('/path/image.pdf'));

and now I simply want to add a black drop shadow.

Can someone help me?

It seems to me impossible to find some example about. It is incredible...

Many thanks!

Answer 1

Ok, here is the solution: if my box contains a filling color, ok, it works; but, if the box contains an image or something else, then I need to use transparencySettings instead of fillTransparencySettings:

var myTransparencySettings = rectbox.transparencySettings;

Then

var rectbox = doc.pages.item(0).rectangles.add({geometricBounds:[20,20,70,120]});
var image = rectbox.place(File('/path/image.pdf'));
var myTS = rectbox.transparencySettings;
myTS.dropShadowSettings.mode = ShadowMode.drop;
...

works perfectly!

Many thanks to Johan, however!

Try this:

var rectbox = doc.pages.item(0).rectangles.add({geometricBounds:[20,20,70,120]});
var image = rectbox.place(File('/path/image.pdf'));
var myFillTransparencySettings1 = rectbox.fillTransparencySettings;
myFillTransparencySettings1.dropShadowSettings.mode = ShadowMode.drop;
myFillTransparencySettings1.dropShadowSettings.angle = 90;
myFillTransparencySettings1.dropShadowSettings.xOffset = 0;
myFillTransparencySettings1.dropShadowSettings.yOffset = 0;
myFillTransparencySettings1.dropShadowSettings.size = 6;
