I want to be able to go to the layer above. I have over 3000 files that i need to select the layer above from and I cannot seem to work out how to do it.
It always has a different name too. But i always start from the same layer and it's always in the same position.
I need this to get the contents of a text layer.
Any ideas? I've been at it a while now but my Javascript knowledge is limited.
Thanks
There might be a smarter way to do this, but the following should work. You can basically tell the layer's z-position by its itemIndex property. So once you have that you can search the one with an itemIndex which is one higher than the current one. When you found it, you can make sure it's a text layer and if so, retrieve it's text contents.
var textContent = "";
var doc = app.activeDocument;
var ix = doc.activeLayer.itemIndex;
for(var i = 0; i < doc.layers.length; i++) {
if(doc.layers[i].itemIndex === ix + 1 && doc.layers[i].kind === LayerKind.TEXT) {
textContent = doc.layers[i].textItem.contents;
break;
}
}
alert("The text content is: " + textContent);

I want to write a script that does the following:
select some textframes
center the selection horizontally
distribute the frames horizontally
the whole routine has to be done on several pages
My first problem is, that I only want to select textframes from a unlocked layer. I found several solutions where all textframes, even on locked layers, were selected.
And the only solution I found so far that just selects the textframes from my unlocked layer (app.menuActions.item("$ID/Select &All").invoke();) doesn't provide an object I can work with (adjust, distribute) afterwards.
Is there a solution to my requirements?
Edit:
My last attempt looked like this (for a single page, I didn't used a loop for several pages while testing):
// 'allPageItems' erfasst alle Rahmen, zusätzlich Gruppen und Bilder
var allObjects = app.activeDocument.layoutWindows[0].activeSpread.allPageItems;
// eine Schleife durch die Objekte
for (var n=0; n<allObjects.length; n++) {
var curObject = allObjects[n];
// prüfen, ob Textrahmen
if (curObject.constructor.name == "TextFrame") {
// verankerte Textrahmen ausschliessen
if (curObject.parent != "[object Character]") {
// zur Auswahl hinzufügen
curObject.select(SelectionOptions.ADD_TO);
}
}
}
Generally, selection is something that is intended for UI interaction, not for scripting. Therefore you should avoid handling all the selection stuff in your script and collect the textFrames as objects in an array that you then can use to do the other stuff.
This should work:
#target indesign
var doc = app.activeDocument;
var curSpread = doc.layoutWindows[0].activeSpread;
var spreadItems = curSpread.allPageItems;
var distObjects = [];
// collect all relevant objects in distObjects
for (var i = 0; i < spreadItems.length; i += 1) {
var si = spreadItems[i];
// skip if itemLayer is locked
if (si.itemLayer.locked) continue;
// skip if item is not a textFrame
if (!(si instanceof TextFrame)) continue;
// skip if item is anchored
if (si.parent.constructor.name === "Character") continue;
distObjects.push(si);
};
// group all collected objects to center them, then ungroup
var distGroup = curSpread.groups.add(distObjects);
doc.align([distGroup], AlignOptions.HORIZONTAL_CENTERS, AlignDistributeBounds.SPREAD_BOUNDS);
distGroup.ungroup();
// distribute all objects horizontally
doc.distribute(distObjects, DistributeOptions.HORIZONTAL_CENTERS, AlignDistributeBounds.ITEM_BOUNDS);
Note: If this is used with an older ID version (prior to CC2014 I believe), after ungrouping, all pageItems will stay on the same layer. The feature for them to move back to the original layer was only introduced recently. If you need a solution for an older InDesign version, you would need to calculate the bounds of the group of objects you found, then offset them all one by one, so the entire "selection" can get centered.
I am having problems in a very simple task in photoshop script, but I am afraid this is not documented elsewhere on the web.
I just want to invert an existing selection, delete the content of the current layer, and then invert back the selection.
Of course this is part of a larger program, and if you are interested, i can provide all details.
Up to know i am making:
// Get current document and current layer
var doc = app.activeDocument;
var activeLay = doc.activeLayer;
var a=0
// find the current layer and assign its code to the variable a
for(i=doc.layers.length-1; i >=0; )
{
if(doc.layers[i]==activeLay)
{
a=i;
alert("a"+a);
break;
}
else{ i--; }
alert ("i"+i);
}
// Now cycle remaining layer under the exsiting one, and jump the selection
// and delete the outer area of selection for each layer
for(i=a-1; i >=0;)
{
// make layer i active
doc.activeLayer=doc.layers[i];
alert ("active layer"+i);
// where is my selection in regards to the active layer?
var s = app.activeDocument.selection.bounds;
var xSo=s[0];
var ySo=s[1];
var xLo = activeLay.bounds[0].value;
var yLo = activeLay.bounds[1].value;
// I have to go from actual selection poisition to the NEXT layer... which i just made active...
DeltaX=xLo-s[0];
DeltaY=ySo-s[1];
doc.selection.translateBoundary(DeltaX,DeltaY);
//Now invert selection and delete
doc.selection.invert
doc.selection.fill (fillType, mode, 0, preserveTransparency) // ??? here what i cannot do?
doc.selection.invert
i--;
}
I found the answer myself...
it is merely
//Now invert selection and delete
doc.selection.invert;
doc.selection.cut();
doc.selection.invert;
my problem was that i didn't know that javascript is case sensitive, and hence .cut() didn't' work for when i misspelled it.
I have a multipage indesign document and in it several layers; one layer is called obrazy and in this layer on every page some frames are placed (the frames are also styled with an object style called obraz), then some of the frames are filled with images and some remain empty; what I need is a script (in javascript) to go through the document end move the empty frames into a different layer (can be new or already existing) which will later be hidden. The script must only manipulate frames in a specific layer or with a specific object style since there are other frames in the other layers.
I have written several versions (and spent hours of experimenting and going through various sources and similar scripts) but still do not have a fully working solution. I guess I am missing some details... Any pointers or suggestions would be very helpful. Thanks.
ok, here is what is now working for me:
var dok = app.activeDocument;
var pocetstran = dok.pages.length;
var vrstvaobrazu = dok.layers.item("obrazy");
for (var j = 0; j<pocetstran; j++) {
for (var i = 0; i < dok.layers.item("obrazy").rectangles.length; i++) {
if ((dok.layers.item("obrazy").rectangles.item(i).images.length == 0)){
dok.layers.item("obrazy").rectangles.item(i).remove();
}
}
}
I am trying to build a small CAD app using HTML5 Canvas and Paper.js
Now I am stuck at a problem I'd hate asking for help for since I believe I should solve this on my own, but everytime I try to think about a solution my head hurts.
I am trying to build the following functions:
Align-left
Align-right
Align-center.
The user is supposed to select a bunch of elements on the canvas and click one of the above functions to align them together.
The whole concept is that the user selects a Reference Item in a way. The elements are aligned relative-to the Reference Item. This ensures that the alignments happen in a user predictable way.
There are 2 ways for the user to select elements
Selection-via-Intersection
The user clicks and drags a selection rectangle. While dragging I
can track in an array which items intersected with the selection
rectangle. I can track the first intersected item here just fine, so I
have a Reference Item .Works perfectly so far.
Selection-via-Click+Shift
The user holds Shift and clicks on elements to do a multi-selection.
It's a functionality I'm sure everyone has seen in any modern graphics
editor. I have yet to figure out a way how to track a first-selected
item here, since items can be set as first-selected and then
deselected.
The problem:
The above selection methods can be COMBINED together -
The user can select-via-intersection and then start select/de-select items using Shift+Click.
Which one from the selectedItems is the Reference-Item now?
An example:
Item 2 was the first-selection on selection-via-intersection. Item 2
was de-selected using Shift+Click. Which one is the Reference-Item
now?.
Here is a GIF that illustrates what I am talking about (although it's invinsible in the GIF the items get selected as soon as the intersection rectangle touches them.)
I am aware that the whole thing will involve some array logic but I cannot seem to grasp how to implement the whole thing.
Notes:
Apart from the complexity of this thing, I have performance constraints as well. Intersection Detection which is used for the Selection-via-Intersection is already a heavy operation and it get's fired continously while the user drags a selection rectangle.
This is the code for Select-Via-Intersection
The following function getSortedIntersects get's called continuously while the user drags a selection rectangle. I log in the console the first selected item:
var checkedSegments = new Array();
function getSortedIntersects(rect) {
//children are all the items drawn on the canvas
var children = project.activeLayer.children;
//I clone the children array into another array and I exclude all items other than Paths
//Intersection Detection works only on paths.
var pathsOnCanvas = children.filter(function (el) {
return el instanceof Path
});
var newCheckedSegments = new Array();
var firstSelection = "";
//Start looping over all Paths on the canvas
for (var i = 0; i < pathsOnCanvas.length; i++) {
//create an array which lists all the intersections. The array is called ''intersections''
var intersections = pathsOnCanvas[i].getIntersections(rect);
//If there is at least 1 intersection OR the rect contains a path then proceed
if (intersections.length > 0 || rect.contains(pathsOnCanvas[i].bounds)) {
//Checks if the selected item at index i is in the newSegments array. If so, it continues iterating the loop without going further at this iteration.
if (newCheckedSegments.indexOf(pathsOnCanvas[i]) >= 0)
continue;
pathsOnCanvas[i].selected = true;
newCheckedSegments.push(pathsOnCanvas[i]);
}
}
for (var i = 0; i < newCheckedSegments.length; i++) {
if (checkedSegments.indexOf(newCheckedSegments[i]) < 0)
checkedSegments.push(newCheckedSegments[i]);
firstSelection = (checkedSegments[0].id);
console.log("first selection is " + firstSelection);
}
for (var i = checkedSegments.length - 1; i >= 0; i--) {
if (newCheckedSegments.indexOf(checkedSegments[i]) < 0) {
checkedSegments[i].selected = false;
checkedSegments.splice(i, 1);
}
}
}
I regularly have two sets of pictures named the same way and I would like to script the process of checking for differences. I'm looking for a basic check, if there is no differences between the two images, discard one of them, if there is a single pixel difference, keep both. For those who question the wisdom of doing this in photoshop, this is an addition to another script that is already running and this optional check will help reduce the number of files I have to upload. I would appreciate the help.
If you really have to do this in Photoshop, this is how I'd propose it:
var doc1 = app.open(new File("~/Desktop/test1.bmp"));
var doc2 = app.open(new File("~/Desktop/test2.bmp"));
doc2.selection.selectAll();
doc2.selection.copy();
app.activeDocument = doc1;
var newLayer = doc1.paste();
newLayer.blendMode = BlendMode.DIFFERENCE;
var histogram = doc1.histogram;
for (var i = 1; i < histogram.length; ++i) {
if (histogram[i] > 0) {
alert('Different!');
break;
}
}
I paste the second picture into the first one and set the resulting layer's blend mode to difference. If the two pictures are identical, the resulting picture should be all black. I therefore check if any color values apart from 0 have any pixels in the histogram.
I assumed the two images have the same size.
