Photoshop - Export layers to files using plugin

Question

I'm using a plugin to export my pngs (https://www.fnordware.com/superpng/) Anyone knows how I can replicate the Export Layers to files functionality that comes with photoshop but export as SuperPNG?

There is export options documentation but only includes the default photoshop formats...

Thanks in advance!

Answer 1

Here's the script I use to save quantified pngs (it uses SuperPNG plugin you mentioned). There're some options in there that I didn't test (with // ??) but by default it saves a png with max quality and transparency. It also checks if you have SuperPNG installed.

exportSuperPng(
{
    path: "/C/Users/Sergey Kritskiy/Desktop/temp", // required
    name: "test-png", // default: document name
    quality: 100, // default: 100 (Highest) 82 is High
    transparency: true, // default: true
})

function exportSuperPng(data)
{
    if (data == void(0)) return false;
    if (data.path == void(0)) return false;
    if (data.quality == void(0)) data.quality = 100;
    if (data.name == void(0)) data.name = activeDocument.name;
    if (data.transparency == void(0)) data.transparency = true;
    if (!getSuperPngInfo()) return false;

    var desc = new ActionDescriptor();
    var descSPng = new ActionDescriptor();
    descSPng.putInteger(charIDToTypeID('pngC'), 9); // ??
    descSPng.putInteger(charIDToTypeID('pngF'), 248); // ??
    descSPng.putInteger(charIDToTypeID('pngS'), 0); // ??
    descSPng.putBoolean(charIDToTypeID('pngQ'), true); // ??
    descSPng.putInteger(charIDToTypeID('pngq'), data.quality); // quality
    descSPng.putEnumerated(charIDToTypeID('pngA'), charIDToTypeID('alfT'), data.transparency ? charIDToTypeID('alfT') : charIDToTypeID('alfN'));
    descSPng.putBoolean(charIDToTypeID('pngX'), false);
    descSPng.putBoolean(charIDToTypeID('pngI'), false); // ??
    descSPng.putBoolean(charIDToTypeID('pngM'), false); // ??
    desc.putObject(charIDToTypeID('As  '), stringIDToTypeID('fnord SuperPNG'), descSPng);
    desc.putPath(charIDToTypeID('In  '), new File(data.path + "/" + data.name + ".png"));
    desc.putInteger(charIDToTypeID('DocI'), 475);
    desc.putEnumerated(stringIDToTypeID('saveStage'), stringIDToTypeID('saveStageType'), stringIDToTypeID('saveSucceeded'));
    executeAction(charIDToTypeID('save'), desc, DialogModes.NO);

    function getSuperPngInfo()
    {
        var sysInfo = app.systemInformation.split("\n");
        for (var i = sysInfo.length - 1; i >= 0; i--)
        {
            if (sysInfo[i].indexOf('SuperPNG') != -1)
            {
                return true
            }
        }
        return false
    }
};

Leaving it here with extra options if anyone needs

exportSuperPng(
{
    path: Folder.desktop, // required
    name: "test-png", // default: document name
    quality: 100, // default: 100 (Highest) 82 is High
    transparency: true, // default: true
    saveMetadata: false,
    cleantransparent:true,
    pInterlacted:false
})

function exportSuperPng(data, path, name)
{
    data.path = path;
    data.name = name;

    if (data == void(0)) return false;
    if (data.path == void(0)) return false;
    if (data.quality == void(0)) data.quality = 100;
    if (data.name == void(0)) data.name = activeDocument.name;
    if (data.transparency == void(0)) data.transparency = true;
    if (data.saveMetadata == void(0)) data.saveMetadata = false;
    if (data.cleantransparent == void(0)) data.cleantransparent = true;
    if (data.pInterlacted == void(0)) data.pInterlacted = false;
    if (!getSuperPngInfo()) return false;

    var desc = new ActionDescriptor();
    var descSPng = new ActionDescriptor();
    descSPng.putInteger(charIDToTypeID('pngC'), 9); // ??
    descSPng.putInteger(charIDToTypeID('pngF'), 248); // ??
    descSPng.putInteger(charIDToTypeID('pngS'), 0); // ??
    descSPng.putBoolean(charIDToTypeID('pngQ'), true); // ??
    descSPng.putInteger(charIDToTypeID('pngq'), data.quality); // quality
    descSPng.putEnumerated(charIDToTypeID('pngA'), charIDToTypeID('alfT'), data.transparency ? charIDToTypeID('alfT') : charIDToTypeID('alfN'));
    descSPng.putBoolean(charIDToTypeID('pngX'), data.cleantransparent);
    descSPng.putBoolean(charIDToTypeID('pngI'), data.pInterlacted);
    descSPng.putBoolean(charIDToTypeID('pngM'), data.saveMetadata);
    desc.putObject(charIDToTypeID('As  '), stringIDToTypeID('fnord SuperPNG'), descSPng);
    desc.putPath(charIDToTypeID('In  '), new File(data.path + "/" + data.name + ".png"));
    desc.putInteger(charIDToTypeID('DocI'), 475);
    desc.putEnumerated(stringIDToTypeID('saveStage'), stringIDToTypeID('saveStageType'), stringIDToTypeID('saveSucceeded'));
    executeAction(charIDToTypeID('save'), desc, DialogModes.NO);

    function getSuperPngInfo()
    {
        var sysInfo = app.systemInformation.split("\n");
        for (var i = sysInfo.length - 1; i >= 0; i--)
        {
            if (sysInfo[i].indexOf('SuperPNG') != -1)
            {
                return true
            }
        }
        return false
    }
};

exportSuperPng();
