Hi:
I want to use the selected area in a automation plugin. In my case, the area is rectangle. i can't get the top,left,bottom and right position.
Is there anyone can help me?

I'm petty you sure can extract the details you want using a script. I think the method is called Selection Bounds, and it return an array of the unitValue of the rectangle.
If you look at the scriptlistener code for creating a rectangle, it does record the data you want. So you should be able to extract it using Javascript, Apple Script or VB
This is what the scriptlistener code looks like,
// =======================================================
var id5 = charIDToTypeID( "setd" );
var desc3 = new ActionDescriptor();
var id6 = charIDToTypeID( "null" );
var ref1 = new ActionReference();
var id7 = charIDToTypeID( "Chnl" );
var id8 = charIDToTypeID( "fsel" );
ref1.putProperty( id7, id8 );
desc3.putReference( id6, ref1 );
var id9 = charIDToTypeID( "T " );
var desc4 = new ActionDescriptor();
var id10 = charIDToTypeID( "Top " );
var id11 = charIDToTypeID( "#Pxl" );
desc4.putUnitDouble( id10, id11, 210.000000 );
var id12 = charIDToTypeID( "Left" );
var id13 = charIDToTypeID( "#Pxl" );
desc4.putUnitDouble( id12, id13, 276.000000 );
var id14 = charIDToTypeID( "Btom" );
var id15 = charIDToTypeID( "#Pxl" );
desc4.putUnitDouble( id14, id15, 455.000000 );
var id16 = charIDToTypeID( "Rght" );
var id17 = charIDToTypeID( "#Pxl" );
desc4.putUnitDouble( id16, id17, 613.000000 );
var id18 = charIDToTypeID( "Rctn" );
desc3.putObject( id9, id18, desc4 );
executeAction( id5, desc3, DialogModes.NO );
