# Coordinates for translations?

Hi there,

i'm knew to all fo this and am quite frankly very lost.

I wish to create a script with six images,( which all seems to be working fine)

my trouble is trying to work out the coordinates(translations) of where i want the photos- I used the x and y top left coordinates from photoshop but when I run the script they end up in a different position. I am so lost and getting extremely frustrated so I would be very grateful if somebody could help me.

Caillte.

• ###### 1. Re: Coordinates for translations?

To you translation, you have to use the change in postion, not the corner of the document.  So you want to get where the layer is currenly and then figure how far you want to move it.  So if your image is as x = 10 and y =20, and you want it at x=50 and y= 5 then you would say:

yourLayer.translate(50-10,5-20)

In code it would look like this:

var docRef = activeLayer

var yourLayer = activeLayer

var wantLayerHereX = 50

var wantLayerHereY = 5

var layerIsHereX = yourLayer.bounds[0]

var layerIsHereY = yourLayer.bounds[1]

yourLayer.translate(wantLayerHereX-layerIsHereX, wantLayerHereY-layerIsHereY)

that's great thatnk you very much!!

for the new position would using the x and y form the centre point be right??

• ###### 3. Re: Coordinates for translations?

The example I gave uses the top left corner, which is most likely the easiest.  You can do the center, but you have to calculate it from the bounds command, which only gives you the corners:

bounds[0] is left side

bounds[1] is top

bounds[2] is right side

bounds[3] is bottom

for center it would be:

x = bounds[2]-bounds[0]

y = bounds[3]-bounds[1]

PasteImageRol Script   This script set a selections for image lactations then paste image into the selection the new layer is masked by Photoshop with the selection  to mask off any excess. The Script also aligns the Layer to the selection but that may not be needed. For the Paste most likely centers the image over the area during the paste into operation.
