Hi,

I would like to make a mirror effect for the foreground. so i have to flip a layer in vertical direction, by move the anchor position to the bottom center.

Could you please help me on this?

thanks,

Here's one method...

flipLayer('v');
//flipLayer('h');
 
function flipLayer(direction) {
switch (direction.toLowerCase()){
    case 'h' : direction = 'Hrzn'; break;
    case 'v' : direction = 'Vrtc'; break;
    default : return;
    }
    var desc23 = new ActionDescriptor();
    desc23.putEnumerated( charIDToTypeID('Axis'), charIDToTypeID('Ornt'), charIDToTypeID(direction) );
 try{
    executeAction( charIDToTypeID('Flip'), desc23, DialogModes.NO );
 }catch(e){}
};

Hi Paul,

It's working well. but I want to create a mirror effect for the foreground.

Could you please check the script one more time with any image?

Is there possible to move the center point into bottom center through coding?

thanks,

If I recall correctly both me & mike had a play about with a similar request over at PS Scripts… There may be something in this that you can utilise… In my case it was just for pretty much square on product stots…
