I am not aware of any alternative method to read the width of an element except using the geometricBounds coordinates.
Select an element and try this:
var gb = app.selection[0].geometricBounds;
var width = gb[3] - gb[1];
alert(width);

script is not selecting these links.
But what are you selecting to check the Transform panel Width?
For example this gets both the linked image width and its container frame width, which is what‘s showing in the Transform panel when I select the frame :
var lnks = app.documents[0].links;
//an image, the link’s parent
var img = lnks[0].parent
//the image bounds and width
var ib = img.geometricBounds
var iw = ib[3]-ib[1]
//the image’s parent container frame bounds and width
var fb = img.parent.geometricBounds
var fw = fb[3]-fb[1]
alert("\rImage Width: " + iw + "\r" + "Container Width: " + fw)
The image direct selected:
Hi @Chandrakanthi26574696ugut , I’m not seeing a problem with the width part of your code, it’s returning the images’ widths. You are declaring a variable for the image’s frame (cont), but not using it.
Also you might need to check if the graphic is an image otherwise you would get an error when you try to get .effectiveResolution.
Here’s an example where I’m getting both the image and its frame widths:
var images = app.activeDocument.allGraphics;
var file = new File(Folder.desktop + "/inddsizes2.txt");
if (file.exists) {
file.remove();
}
//declare the loop variables
var ef, pp, cont, w, fw, data, newdata;
for (var i=0; i<images.length; i++) {//images.length
//make sure the graphic is an image
if (images[i].constructor.name == "Image") {
pp = images[i]//the image
cont = pp.parent;//the image frame
eff = pp.effectivePpi; //returns the vertical and horizontal as an array
//if either the vertical or horizontal res exceeds 320
if(eff[0] || eff[1] > 320){
//the scaled image width
w = Math.round(pp.geometricBounds[3]-pp.geometricBounds[1]);
//the image frame width
fw = Math.round(cont.geometricBounds[3]-cont.geometricBounds[1])
if (file.exists) {
file.open("a");
newData = images[i].itemLink.filePath+" - Image Width: "+w+ " Frame Width: " + fw + "\n"
file.write(newData);
file.close();
} else {
data = images[i].itemLink.filePath+" - Image Width: "+w+ " Frame Width: " + fw + "\n"
file.open("w");
file.write(data);
file.close();
}
}
}
if(i == (images.length-1)){
alert('files marked for PS')
}
}
The result
I meant to ask if you were rotating your page items—geometricBounds gets the bounds of the image on the page including any rotation or skewing, so to get the actual scaled image width via geometricBounds you would have to set any rotation or skew to 0, get the geometric bounds, then reset.
Here the width of the image is 165.594mm, but the space it takes up on the page (geometricBounds) is 178.8mm.
I assume you plan to manually downsample the images over 320ppi in Photoshop? Why not let the downsampling happen on a PDF Export?
A doughnut from your document - left is the original one - right is after resetting rotation:
The value that is on the screenshot - InDesign values (top-left green rect) - are for the left object - image selected in the InDesign.
Highlighted in green are the values for the right object - after resetting angle to "0".
Groups of objects:
And here are the Width & Height values calculated from the GeometricBounds:
I'm not doing rounding - so values are "almost 0".
And full document's structure:
If I add lines to set the image rotation and shear to 0 to @Chandrakanthi26574696ugut ‘s code I still get different width calculations for one of the example files.
Here the image on the right has no rotations and the image on the left was copied from the example file and has rotations applied to both the image and its frame—they are returning different widths even though there rotations have both been set to 0—the actual width is 166:
The code with image rotation and shear set to 0
