resizing or moving an opacity mask along with the items inside it

[Guest]

I'm trying to resize a opacity mask by doing

transMaskItem.resize(

  10, //scaleX,

  10, //scaleY,

  true, //[,changePositions]

  true, //[,changeFillPatterns]

  true, //[,changeFillGradients]

  true, //[,changeStrokePattern]

  0.1, //[,changeLineWidths]

)

This resizes the item, but it does not resize the item inside it. I tried similar command with the translation command

transMaskItem.translate(

100, //([deltaX]

100. //[,deltaY]

True, //[,transformObjects]

True, //[,transformFillPatterns]

True, //[,transformFillGradients]

True, //[,transformStrokePatterns])

and similar thing happened. The item gets moved, but the object inside it doesn't.

How do I resize or translate an opacity mask along with the items inside it?

let us know what transMaskItem is referring to.

[Guest]

it's the PageItem that refers to the opacity mask object.

it seems you're grabbing a hold of the actual mask, you need to resize the "whole" group.

show some more of your code.

Here is my code:

doc = app.activeDocument;

doc.selectObjectsOnActiveArtboard();

for ( i = 0; i < doc.Selected.length; i++ ) {

    doc.Selected.resize(10, 10, true, true, true, true, 0.1);

     doc.Selected.translate(100, 100, true, true, true, true);

}

I see...it seems to be a bug, the actual mask gets ignored. Probably to be consistent with the user interface, you can not select the mask with the mouse either.

maybe someone else has found a way to work with Opacity Masks, I haven't.

as a side note, there's no need to select the objects in order to size them or move them, you can just reference them. Also, there's no "Selected" object, change that to "selection".

Is this still a bug? Facing the same issue even with Adobe CC 2014 version.

Hey!

I'm still bumping into this problem in CC 2015 😞

I haven't found a good way to resize an opacity mask, but a work-around for translating them is to translate the artboard bounds in the opposite direction.

var doc = app.activeDocument;
var bounds = doc.artboards[0].artboardRect;
var dX = -72; // one inch (in points) to the left, mask will move to the right
var dY = 144; // two inches (in points) up, mask will move down
var wid = Math.abs( bounds[2] - bounds[0] );
var hei = Math.abs( bounds[3] - bounds[1] );
// assume that the active layer is unlocked and visible
var tempRect = doc.activeLayer.pathItems.rectangle( bounds[1] + dY, bounds[0] + dx, wid, hei );
doc.artboards[0].artboardRect = tempRect.geometricBounds;
tempRect.remove(); 

You will need to also move any elements that you want to "stay in the same place", so this hack probably won't work if you have multiple opacity masks and don't want to translate them all.

Another way:

var effectStr =  '<LiveEffect name="Adobe Transform">'
    + '<Dict data="B transformPatterns 0 R scaleV_Factor 1.2 R moveH_Pts 0 R scaleV_Percent 120 B reflectX 0 B scaleLines 0 B reflectY 0 I numCopies 0 B randomize 0 R scaleH_Factor 1.2 R rotate_Radians 0 I pinPoint 4 R moveV_Pts 0 R rotate_Degrees 0 R scaleH_Percent 120 B transformObjects 1 "/>'
    + '</LiveEffect>';  
app.selection[0].applyEffect(effectStr);
app.redraw();
app.executeMenuCommand('expandStyle');
