[AS/CC]Resizing a box and its contained image

Is there a method ro resize by percentage a box and the image inside?

My code for this is the following:

(first line for the box, second for the image)

  resize selection in inner coordinates from top left anchor by multiplying current dimensions by values {0.75, 0.75} with resize individually and considering ruler units
  resize image 1 of selection in parent coordinates from top left anchor by multiplying current dimensions by values {0.75, 0.75} with resize individually and considering ruler units

But unfortunately, if the image is skewed, the result is not what we can expect: the image is resized, but misplaced.

Any suggestion?

Well. There is another method:

use a transformation matrix.

 

/*
Scales the selected object with the image to 50%:
scaleMatrix( .5 , .5 )
through method transform() on the selection.
*/

var mySel = app.selection[0];

var myTransformationMatrix = 
app.transformationMatrices.add
(
{
horizontalScaleFactor:1, 
verticalScaleFactor:1
}
);

myTransformationMatrix = 
myTransformationMatrix.scaleMatrix(.5, .5);

mySel.transform
(
CoordinateSpaces.pasteboardCoordinates, 
AnchorPoint.centerAnchor, 
myTransformationMatrix
);

 

And that seems to be the solution.

Rectangle plus image scaled in one go.

 

Here the proof with two overprinting rectangles overlapping perfectly. One scaled with the script above, one scaled with the UI. No shift visible.

And here a PDF about using transform() with a transformationMatrix:

If AppleScript behaves the same as JavaScript in this regard, then the answer is 'no', there is no single command for that. I wouldn't resize the image after resizing the rectangle, by the way, but fit the image to the rectangle, which would ensure a good fit. In JS:

myFrame.resize // as you have it

myFrame.fit (FitOptions.contentToFrame)

Peter,

Unfortunately, your suggestion is invalid for my script:

I want to modify cropped, scaled and even rotated images.

So I have to write tons of code to re-place those images.

I'm dreaming of a <resize myFrame with content> command!

Why can't we do by scripting things we can do manually? (this is for Adobe developpers, of course (and I know they are rarely visiting this board…))

Thank you anyway…

Here another close up of both overlapping rectangles showing the shift:
