Is there a way to align a layer to the "outside" of a selection?

I have a layer and I have a selection on my canvas, I wanna align this layer to the outside part of the selection, be it the bottom outside, or the up outside or the sides, I think the align buttons only allow me to align the layer to the inside of the selection.

See in the image, I wanna be able to align the image to be outside and beneath the selection box.

We can make alignment more interactive:

To get alignment to the outer edge, you need to save the script to the prest folder, run it from the menu, activate event tracking and then press shift while aligning to one of the sides. Unfortunately, such an alignment will not be recorded in the action, but it is quite suitable for manual work.

Based on @Stephen Marsh code.

Try the following script (original code updated to work correctly with a Background layer):

/*
Align Top of Layer to Bottom of Selection.jsx
https://community.adobe.com/t5/photoshop-ecosystem-discussions/is-there-a-way-to-align-a-layer-to-the-quot-outside-quot-of-a-selection/td-p/13132396
v1.0 - 13th August 2022, Stephen Marsh
*/

// Save the current ruler units and set to pixels
var savedRuler = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;

// Selection lower edge value
var selY2 = activeDocument.selection.bounds[3].value;

// Save the selection as a temp channel
activeDocument.selection.store(activeDocument.channels.add());
activeDocument.channels[activeDocument.channels.length-1].name = "_tempChannel";
activeDocument.activeChannels = activeDocument.componentChannels;

// Deselect
activeDocument.selection.deselect();

// Active layer upper edge value
var layY1 = activeDocument.activeLayer.bounds[1].value;

// Difference between lower and upper edge values
var diff = layY1 - selY2;

// Move using the (negative) difference value
activeDocument.activeLayer.translate(0, -diff);

// Load the temp channel selection
activeDocument.selection.load(activeDocument.channels.getByName("_tempChannel"), SelectionType.REPLACE);

// Remove the temp channel
activeDocument.channels.getByName("_tempChannel").remove();

// Restore the ruler units
app.preferences.rulerUnits = savedRuler;

This script does exactly what I need, thank you. It's weird that there isn't a built in way to align outside of the stuff. In this case, is there a way to make this code ask if I wanna align the text to the up part of the selection, or the right or the left and bottom, just to make this function more complete to anyonelse that needs it?

This works, but it is messy.

Make the selection into a workpath (icon at bottom of paths panel)

Select the Type tool. Hover over the bottom of the workpath till you see the double arrow cursor, and type.

If the text is placed inside the workpath, use the Path Selection tool (black arrow) and drag it to where you want it.

Make the type layer a Smart Object (right click menu)

Use Free Transform and flip horizontally and vertically

This might be more hassle than it's worth, but...

Select > Transform Selection
This allows you to extend the sides of the selection, that you won't be aligning to, to the edge of the document.

Select > Inverse
Reverses the selection.

Then use the align options while using the Move Tool.

@Michael Bullo – Excellent! I like this and will likely look into it further, just for fun.

@Stephen Marsh - Thanks mate. I've got a lot of respect for the work you do and I am curious to see what you might do with this method.

@Michael Bullo

I had a play with your suggestion and came up with both an Action and Script.

Action screenshot:

Script version of the action:

(Script code updated on 20th August 2022)

// Save the current ruler units and set to pixels
var savedRuler = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;

// Selection bounds
var selectionBounds = activeDocument.selection.bounds;
var selectionLeft = selectionBounds[0].value;
var selectionTop = selectionBounds[1].value;
var selectionRight = selectionBounds[2].value;
var selectionBottom = selectionBounds[3].value;
var selectionWidth = selectionBounds[2].value - selectionBounds[0].value;
var selectionHeight = selectionBounds[3].value - selectionBounds[1].value;

// Calculate the selection extension values
var extendSelLeft = selectionLeft - 0;
var extendSelRight = activeDocument.width.value - selectionRight;
var extendSelTop = selectionTop - 0;

// Save the selection as a temp channel
activeDocument.selection.store(activeDocument.channels.add());
activeDocument.channels[activeDocument.channels.length-1].name = "_tempChannel";
activeDocument.activeChannels = activeDocument.componentChannels;

// align using the lower middle anchored transform
bottomCentre();

// Load the temp channel selection
activeDocument.selection.load(activeDocument.channels.getByName("_tempChannel"), SelectionType.REPLACE);

// Remove the temp channel
activeDocument.channels.getByName("_tempChannel").remove();

// Restore the ruler units
app.preferences.rulerUnits = savedRuler;


/***** Functions *****/

function bottomCentre() {
    // Resize the selection to canvas left, top, right
    activeDocument.selection.resizeBoundary( extendSelLeft + selectionWidth + extendSelRight, selectionHeight + extendSelTop, AnchorPosition.BOTTOMCENTER );
    // Inverse selection
    var idinverse = stringIDToTypeID("inverse");
    executeAction(idinverse, undefined, DialogModes.NO);
    align2Selection('AdCH');
    align2Selection('AdTp');
    activeDocument.selection.deselect();
}

function align2Selection(method) {
    /* 
    AdLf = Align Left
    AdRg = Align Right
    AdCH = Align Centre Horizontal
    AdTp = Align Top
    AdBt = Align Bottom
    AdCV = Align Centre Vertical
    */
    var desc = new ActionDescriptor();
    var ref = new ActionReference();
    ref.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
    desc.putReference(charIDToTypeID("null"), ref);
    desc.putEnumerated(charIDToTypeID("Usng"), charIDToTypeID("ADSt"), charIDToTypeID(method));
    try {
        executeAction(charIDToTypeID("Algn"), desc, DialogModes.NO);
