Transform a group of layers to all reach the top and bottom of canvas

Hello,

I am loading in a bunch of images of varying sizes. They scale to the sides by default in photoshop. However, for my purpose it would be better if they all scaled to the top and bottom. Is there any way to dfo this within photoshop natively, or a script to do this if not?

Thank you!

Okay, try this script. It will cycle through all the Smart Object layers at the top level and resize them. It will not do any layers in groups.

#target photoshop 
var doc = activeDocument
app.preferences.rulerUnits = Units.PIXELS;
var layBounds

for(var i=0;i<doc.layers.length;i++){
    doc.activeLayer = doc.layers[i];
    layBounds = doc.activeLayer.bounds;
    if(doc.activeLayer.kind == 'LayerKind.SMARTOBJECT'){
        var ratio =doc.height.value/ (layBounds[3].value-layBounds[1].value);
        doc.activeLayer.resize (ratio *100, ratio*100);
        layBounds = doc.activeLayer.bounds;
        var soCenterX = (layBounds[0].value + layBounds[2].value)/2
        var soCenterY = (layBounds[1].value + layBounds[3].value)/2
        doc.activeLayer.translate ((doc.width.value/2)-soCenterX, (doc.height.value/2)-soCenterY)
        }
    }//end for loop

@happyplant1111 - So how did the latest script from Chuck work for you?

Here I have combined the script from @Chuck Uebele with some code from @jazz-y to process selected layers... The script will select all layers then resize them. A single history step undo is also included.

*/

#target photoshop

function main() {

    // Select all layers except the Background layer
    app.runMenuItem(stringIDToTypeID('selectAllLayers'));

    ///// Process selected layers - from jazz-y /////
    var s2t = stringIDToTypeID;
    (r = new ActionReference()).putProperty(s2t('property'), p = s2t('targetLayersIDs'));
    r.putEnumerated(s2t('document'), s2t('ordinal'), s2t('targetEnum'));
    var lrs = executeActionGet(r).getList(p),
        sel = new ActionReference();
    for (var i = 0; i < lrs.count; i++) {
        sel.putIdentifier(s2t('layer'), p = lrs.getReference(i).getIdentifier(s2t('layerID')));
        (r = new ActionReference()).putIdentifier(s2t('layer'), p);
        (d = new ActionDescriptor()).putReference(s2t("target"), r);
        executeAction(s2t('select'), d, DialogModes.NO);

        ///// Resize Active Layer to Doc Height - from Chuck Uebele ///// 

        var doc = activeDocument;

        var layBounds = doc.activeLayer.bounds;
        var ratio = doc.height.value / (layBounds[3].value - layBounds[1].value);
        doc.activeLayer.resize(ratio * 100, ratio * 100);
        layBounds = doc.activeLayer.bounds;
        var soCenterX = (layBounds[0].value + layBounds[2].value) / 2;
        var soCenterY = (layBounds[1].value + layBounds[3].value) / 2;

        doc.activeLayer.translate((doc.width.value / 2) - soCenterX, (doc.height.value / 2) - soCenterY);

    }
}
app.activeDocument.suspendHistory("Resize Selected Layers to Doc Height", "main()");

Wow you guys rock! I will give this a try in a bit and report back. Thanks!!

// Resize Active Layer to Doc Height.jsx

// Set the ruler units
var originalRulerUnits = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;

// Target height
var docHeight = activeDocument.height.value;

resizeToDocHeight();

// Reveal hidden content
//activeDocument.revealAll();

// Restore the original ruler units
app.preferences.rulerUnits = originalRulerUnits;


function resizeToDocHeight() {
    if (!documents.length) return;
    var startRulerUnits = app.preferences.rulerUnits;
    app.preferences.rulerUnits = Units.PIXELS;
    var doc = app.activeDocument;
    // var res = doc.resolution;
    var dHeight = doc.height;
    var LB = activeDocument.activeLayer.bounds;
    var Height = LB[3].value - LB[1].value;
    var onePix = 100 / Height;
    var newSize = onePix * dHeight;
    doc.activeLayer.resize(newSize, newSize, AnchorPosition.MIDDLECENTER);
    app.preferences.rulerUnits = startRulerUnits;
}

This is also close to what I need but the same issue as @Chuck Uebele 's

After running it seems to only scale based upon the largest layer and the smaller layers are not scaled vertically.

Not in my tests.

My canvas was intentionally landscape, with the height the required size. After all layers were scaled to the doc height, the trim command, crop tool or canvas size command can centre crop.

Try this script. It will transform a layer to the height of the document and center it. This script will only transfor the selected layer.

@Stephen Marsh Something must have changed, as I didn't have any issues transforming a scaled smart object.

#target photoshop 
var doc = activeDocument

var layBounds = doc.activeLayer.bounds;
var ratio =doc.height.value/ (layBounds[3].value-layBounds[1].value);
doc.activeLayer.resize (ratio *100, ratio*100);
layBounds = doc.activeLayer.bounds;
var soCenterX = (layBounds[0].value + layBounds[2].value)/2
var soCenterY = (layBounds[1].value + layBounds[3].value)/2

doc.activeLayer.translate ((doc.width.value/2)-soCenterX, (doc.height.value/2)-soCenterY)

Hi Chuck, you are right, I tried with/without the below code with the same result:

// Reset SO transformations
var idplacedLayerResetTransforms = stringIDToTypeID( "placedLayerResetTransforms" );
executeAction(idplacedLayerResetTransforms, undefined, DialogModes.NO);

I too modified an existing script, however, you beat me to it! I may as well post the code anyway...

I most likely can be done with a script, but sizing smart objects in a script can be tricky if they've been previous scaled, which seems to be the case, in your situation. I bet @jazz-y knows how to scale them properly.

I think portrait is the problem for receiving portrait images. If the target is landscape they would resize to the correct height. Then the trim would make a portrait canvas. Or so goes my untested theory.

I think that SL can record resetting the SO transform, or it may not matter to just resize the SO a second time to proportionally scale to canvas height.

I believe the issue with transforming SOs is that if it has been transformed say 10% smaller, and you get the bounds of the current size and you figure you need to reduce it 20%, well it will throw out that original 10% resize and the new transform will be 20% when it should have been 30%. You need to find out the current transform before you transform. At least I think that is the issue.
