Add a little height to text box in indesign?

Report · Jul 06, 2016

Hi!

I have a big and nice script that applies height/width changes to a document based on object styles and other parameters.

But what I really need is a script that just adds a little height to a selected text box. It does not have to rely on object styles and should apply only to one box.

I'm learning to program, but have no javascript skills so far...

Is there any way to cut down the script under?

You have very many ways to achieve that. But if goal is to increase selection height, what could possibly a script offer more than just typing in the transformation info ?

Report · Jul 06, 2016

It's part of a bigger script with many steps, so I don't want it done manually.

Report · Jul 06, 2016

ok but what do you want exaclty ?:

a) Set an explicit height

b) increase height by x units (and then from which reference point ?)

c) increase height proportionnaly (and then from which reference point ?)

Thanks for your answer. To be specific:

1. Set current height = height;

2. Set reference point top middle point.[in a 3x3 grid]. (or one of the three top points, really?)

3. Add height by x units. Do not increase proportionally.

Width is not affected.

var resizeItem = function(item, h) {
  const cs = CoordinateSpaces.INNER_COORDINATES,
  ap = AnchorPoint.TOP_LEFT_ANCHOR,
  rm = ResizeMethods.ADDING_CURRENT_DIMENSIONS_TO;
  item.resize  ( cs, ap, rm, [0,h] );
  }
var h = new UnitValue ( "2mm").as("pt");
resizeItem ( app.selection[0], h );

Here you are

Hi Loic, my solution was to change the gBs, but you was a bit faster .

var changeHeight = 20;
var curSel = app.selection[0];
var gB = curSel.geometricBounds;
gB[2] = gB[2] + changeHeight;
curSel.geometricBounds = gB;

What is the benefit to use resize instead of changing the bounds? Thanks.

Hi Kai,

Not sure one is deeply better than the other. I looked at performance, it seems delays are similar.

Possibly better not to call a method and prefer using properties as you did though for performance.

Really can't say. If I had to defend my snippet, I may advance that using UnitValue you may push wathever values.

But even then, it's easy to set measurement units to whatever.

I didn’t know 'UnitValue' before. It seems that 'new' is not needed?! Pretty cool. Thanks.

UnitValue object is explained in the Javascript Tool guide. It's a great tool that avoid using approximative conversion rations between units.
