[JS] Resize layers with a specific interpolation method?

Hi Stephen,

Sorry for the late answer, I didn't take the time to work on this project since.

The script seems to indeed use the right interpolation type when I use it to resize a layer, so this is great!

But your example seems to only use percent units for the resizing. Is there any way we can use pixels units instead?
I tried to copy the "pixelsUnit" value you set for the horizontal and vertical parameters in the height and width parameters, but it still rescale it with percent units somehow.

In this script for example, the layers will be resized by 32% instead of 32x32px:

try {
    var doc = app.activeDocument;
    var originalLayer = doc.activeLayer; // (We assume it is always a square image)

	var bicubicResizedLayer = originalLayer.duplicate();
	doc.activeLayer = bicubicResizedLayer;
	transformLayer(32, 32, "bicubic")
	
	var neighborResizedLayer = originalLayer.duplicate();
	doc.activeLayer = neighborResizedLayer;
	transformLayer(32, 32, "nearestNeighbor")
} catch (e) {
    alert("Error : " + e.toString());
}

function transformLayer(width, height, interpolationType) {
	function s2t(s) {
        return app.stringIDToTypeID(s);
    }
	var descriptor = new ActionDescriptor();
	var descriptor2 = new ActionDescriptor();
	var reference = new ActionReference();
	reference.putEnumerated( s2t( "layer" ), s2t( "ordinal" ), s2t( "targetEnum" ));
	descriptor.putReference( s2t( "null" ), reference );
	descriptor.putEnumerated( s2t( "freeTransformCenterState" ), s2t( "quadCenterState" ), s2t( "QCSCorner0" )); // 0 = upper left
	descriptor2.putUnitDouble( s2t( "horizontal" ), s2t( "pixelsUnit" ), 0 ); // horizontal
	descriptor2.putUnitDouble( s2t( "vertical" ), s2t( "pixelsUnit" ), 0 ); // vertical
	descriptor.putObject( s2t( "offset" ), s2t( "offset" ), descriptor2 );
	descriptor.putUnitDouble( s2t( "width" ), s2t( "pixelUnit" ), width );
	descriptor.putUnitDouble( s2t( "height" ), s2t( "pixelUnit" ), height );
	descriptor.putBoolean( s2t( "linked" ), true );
	descriptor.putEnumerated( s2t( "interfaceIconFrameDimmed" ), s2t( "interpolationType" ), s2t( interpolationType )); // "bicubic" / "nearestNeighbor"
    executeAction(s2t("transform"), descriptor, DialogModes.NO);
}
