Playing with Zoom percentages! …

Hi all,

I have a document where all pages have different dimensions!

E.g.: a 4-pages document,

page 1 = 40 mm W  x 12 mm H;

page 2 = 185 mm W  x 312 mm H;

page 3 = 151 mm W  x 72 mm H;

page 4 = 229 mm W  x 144 mm H.

When I resize each page to window, I get different zoom-percentages!

page 1 = 925%;

page 2 = 82%;

page 3 = 290%;

page 4 = 172%.

I would like to compare all the percentages and keep the smaller [82%] and apply this zoom to all the pages! 

My beginning is:

var myTarget = app.documents[0];
for (i=0; i < app.layoutWindows.length; i++)
{
app.layoutWindows.zoom(ZoomOptions.FIT_PAGE) ;
myZoom = myTarget.layoutWindows.zoomPercentage;
……
}
……

              

I've no real idea about how finish this script!

Thanks for your help!

Hello,

Something like this :

var main = function () {
  var d = app.properties.activeDocument,
  minZoom, ps, p, n, l, zp;
  if ( !d ) return;
  l= d.layoutWindows[0];
  ps = d.pages;
  n = ps.length;
  while (n--) {
  p = ps;
  l.activePage = p;
  l.zoom ( ZoomOptions.FIT_PAGE );
  zp = l.zoomPercentage;
  (!minZoom || minZoom<zp ) &&  minZoom = zp; 
  }
  l.zoomPercentage = minZoom;
}
var u;
app.doScript ( "main();",u,u,UndoModes.ENTIRE_SCRIPT, "ReZoom" );

If you're into one-liners, this is the one for you, using the undocumented (in the ESTK) .apply() function:

Math.min.apply (null, app.layoutWindows.everyItem().zoomPercentage);

everyItem() is as good a friend as Math.min!

    Hi Jongware, Loïc and Peter,

    Loïc's approach works fine, except a small error at line 14:

    (!minZoom || minZoom>zp ) &&  minZoom = zp;

    … but I'm interested to explore the "Math.min" way! I'm working on it too!

    Thanks to both of you!

    Math.min is your friend.

    Set myZoom to the zoom of the first document, thenset it to

    myZoom = Math.min(myZoom, myTarget.layoutWindows[0].zoomPercentage):

    in the loop. At the end, myZoom will contain the smallest value of all.
