change second page size in 3-page spread

[oleh_melnyk]

Hi,

I'm wondering, how can I change second page size in 3-page spread with ExtendScript?

(I'm trying to generate cover with spine)

[oleh_melnyk]

oh, come on! nobody knows how to do this with a script?

[Vamitul · Accepted solution]

app.activeWindow.activeSpread.pages[1].resize(CoordinateSpaces.innerCoordinates, AnchorPoint.centerAnchor, ResizeMethods.ADDING_CURRENT_DIMENSIONS_TO, [-1000, 0])

any ideas how to set size in mm instead of pixels?

and set exact size for "page" (spine), instead of counting from left page? for example spine should be 5 mm width and 303 mm tall

found it here!

function setWidthHeight(/*PageItem*/o, /*str*/w, /*str*/h, /*bool=false*/useVisibleBounds)

{

  if( !o.resize ) return;

  var CS_INNER = CoordinateSpaces.INNER_COORDINATES,

  BB = BoundingBoxLimits[(useVisibleBounds?'OUTER_STROKE':'GEOMETRIC_PATH') + '_BOUNDS'];

  var wPt = UnitValue(w).as('pt'),

  hPt = UnitValue(h).as('pt');

  if( 0 >= wPt || 0 >= hPt ) return;

  o.resize(

  [CS_INNER,BB],

  AnchorPoint.CENTER_ANCHOR,

  ResizeMethods.REPLACING_CURRENT_DIMENSIONS_WITH,

  [wPt,hPt,CS_INNER]

  );

}

// Sample code

// ---

setWidthHeight(app.selection[0], "5cm", "50pt");

Resize works in points, not pixels.

To convert between units use UnitValue

The resize method: Page
