Hi,

Just after some scripting help.  I have a simple script that works fine =
when run without a GUI, but if I use exactly the same code in a version =
with a GUI it doesn=E2=80=99t work any more.

The aim is to sample the colour of a layer.  The script applies a colour =
control / expression control effect, with an expression that uses =
sampleImage to read the RGB values.  The script then reads the value of =
the colour control to get the RGB values.

As I said - works fine if I run the script from the scripts menu.  But =
the same thing in a GUI and run from the ScriptsUI Panel doesn=E2=80=99t =
work. The RGB array variable is just 0. So what am I doing wrong?

Cheers,


-Chris

Offending code:

myLayer[0].property("ADBE Effect Parade").addProperty("ADBE Color =
Control=E2=80=9D);

myLayer[0].property("ADBE Effect Parade").property("ADBE Color =
Control").property("ADBE Color =
Control-0001").expression=3D"x=3DthisLayer.width/2;y=3DthisLayer.height/2;=
 c=3DsampleImage([x,y], radius =3D [2, 2], postEffect =3D true, t =3D =
time);";

var RGB=3DmyLayer[0].property("ADBE Effect Parade").property("ADBE Color =
Control").property("ADBE Color Control-0001").value;
