Putting IPTC data into pixels, underneath image

[Bjorn]

Hi,

A few years ago, I remember I came across a plug-in which could "convert" an image's IPTC info into pixels and write it underneath the image. Can't remember the plug-in's name though.... I tried google, but no luck there.

So the question now is: Is it possible to do this with a script?
Ideally, I would like to:

1) open image
2) extend the image's canvas by 50px further down
3) with bespoke "script": read "IPTC Caption" + "IPTC City" + "IPTC Country" and write it into a text-layer into that 50px canvas-extension. So it reads something like "Golden Gate Bridge, San Francisco, USA"
4) merge layers
5) save file

I know how to write Photoshop-Actions, so these 5 steps are easy.
However, with step 3 I would need help – as my Javascript knowledge is very limited. Can someone here maybe help me with this?

Thank you very much!
Bjorn

This should get you started...

Code: Select allvar doc= activeDocument;
var originalRulerUnits = preferences.rulerUnits;
preferences.rulerUnits = Units.PIXELS;
var Desc = doc.info.caption;
var City = doc.info.city;
var Country = doc.info.country;
var addTextArea = 50;
var white = new SolidColor();
white.rgb.hexValue = 'ffffff';
app.backgroundColor = white;
var Width = doc.width;
var Height = doc.height + addTextArea;
doc.resizeCanvas(Width , Height , AnchorPosition.TOPCENTER);
var fontSize = 20;
var fontName = "Helvetica";
var textColor = new SolidColor;
textColor.rgb.hexValue = '000000';    
var newTextLayer = doc.artLayers.add();
newTextLayer.kind = LayerKind.TEXT;
newTextLayer.textItem.kind = TextType.POINTTEXT
newTextLayer.textItem.color = textColor;
newTextLayer.textItem.font = fontName;
newTextLayer.textItem.size = fontSize;
newTextLayer.textItem.contents =Desc + ", " + City + " , " + Country;
newTextLayer.textItem.position = Array(10, Height - (addTextArea/2));
preferences.rulerUnits = originalRulerUnits;
