May be you can use 'RasterItem.resolution' method which returns a double value (in dpi).

Thanks for your reply.

I have found another script which returns the dpi of linked images.

I am not so good in scripting could you have a look in this and convert to RasterItem.resolution.

var docRef = activeDocument;

with (docRef) {

// We are expecting 1 placed item (image) here!!!

var placedWidth = placedItems[0].width;

var placedHeight = placedItems[0].height;

var placedPath = placedItems[0].file;

// The 2 variables below are global

XpixelDimension = 0;

YpixelDimension = 0;

// Call the function

exifDimensions(placedPath);

// Calculate the Height & Width DPI's

var widthDPI = Math.floor(XpixelDimension / (placedWidth / 72));

var heightDPI = Math.floor(YpixelDimension / (placedHeight / 72));

alert('Width DPI is ' + widthDPI + ' Height DPI is ' + heightDPI);

}

function exifDimensions(imageFilePath) {

imageFilePath.open('r');

try {

while (imageFilePath.tell() < imageFilePath.length) {

var line = imageFilePath.readln();

var idxOf = (line.indexOf('<exif:PixelXDimension>') > -1) ? line.indexOf('<exif:PixelXDimension>') : line.indexOf('<exif:PixelYDimension>');

if(idxOf > -1) {

if(line.indexOf('<exif:PixelXDimension>') > -1) XpixelDimension = parseInt(line.substring(line.indexOf(">")+1, line.lastIndexOf("<")));

else YpixelDimension = parseInt(line.substring(line.indexOf(">")+1, line.lastIndexOf("<")));

}

catch (ex) { alert('Fluff');}

finally { imageFilePath.close(); return [XpixelDimension, YpixelDimension]; }

}

Thanks in advance

That script is ages old and works by going and finding the linked/placed file and parsing data from it… In your case the file is in the file… NO link?

RasterItem does not have a .resolution property. RasterizeOption does.

Thanks, Carlos. It's interesting that I got the MVP thing. Click the question mark under the MVP in the right hand column and check it out.

Hey, it's actually possible to win something with the formerly so useless brownie points!

I'd like a real Adobe Mug, as seen in the Corporate Identity PDF on p. 38 -- how many points does that need?

Yeah, and I'm truely surprised that you didn't get one of the MVP tags with all that you contribute here and in the InDesign fora.

No need to be surprised.

You are only seeing the positive merits, the "plus" side of it. Unbeknownst to you, me, and the other forum members, there may be a minus list as well. If one gets added (subtracted perhaps) for every inappropriate remark, bad joke, condescending answer, jab to Adobe in general / Adobe staff / Adobe programmers / Adobe support / Adobe corporate desicion, actual complaint, or bashing down on this infernal Jive editor, well, I'm pretty sure my minuses would stick out of the left side of your screen. ... into the next room, perhaps.

mmm...you're being punished Jong, if that was true then I have to start behaving to someday get to be an mvp hahaha....I was wondering why some of the top contributors in the regular AI forum didn't get the MVP badge, then I checked and Steve, Scott F, mike and James are under the 5,000 points (not that it is required i guess, there are a couple mvp's with around 2,000 points)...interesting that the top two, Wade and Jacob didn't get it either....I wonder if some of them declined....
