View Layer Mask status via scripting

[greenrookie]

Greetings all,

Does anyone know if I can check if the view layer mask (the greyscale thumbnail next to the layer) is on or off via scripting?

Thanks in advance!

#target photoshop
s2t = stringIDToTypeID;
(r = new ActionReference()).putProperty(s2t('property'), p = s2t('userMaskEnabled'));
r.putEnumerated(s2t("layer"), s2t("ordinal"), s2t("targetEnum"));
if (executeActionGet(r).hasKey(p)) alert (executeActionGet(r).getBoolean(p));

Thanks jazz-y for your quick reply.

I'll try to clarify a bit more about what I need below.

alert(layerMaskHasContent())
function layerMaskHasContent() {
    #target photoshop
    s2t = stringIDToTypeID;
    (r = new ActionReference()).putProperty(s2t('property'), p = s2t('hasUserMask'));
    r.putEnumerated(s2t("layer"), s2t("ordinal"), s2t("targetEnum"));
    if (executeActionGet(r).getBoolean(p)) {
        (r = new ActionReference()).putEnumerated(s2t("channel"), s2t("channel"), s2t('mask'));
        (d = new ActionDescriptor).putReference(s2t("null"), r);
        executeAction(s2t("select"), d, DialogModes.NO);
        (r = new ActionReference()).putProperty(s2t('property'), p = s2t('histogram'));
        r.putEnumerated(s2t("channel"), s2t("ordinal"), s2t("targetEnum"));
        var hst = executeActionGet(r).getList(p);
        (r = new ActionReference()).putEnumerated(s2t("channel"), s2t("channel"), s2t('RGB'));
        (d = new ActionDescriptor).putReference(s2t("null"), r);
        executeAction(s2t("select"), d, DialogModes.NO);
        for (var i = 0; i < hst.count - 1; i++) { if (hst.getInteger(i)) return true }
        return false
    }
}

Thanks so much, both work as intended.

Sorry I made an error in my image, but I could not change it after posting...

I just mean check if view mask (activated by option click on Mac) is visible (the white/greyscale mask) = true

Normal left view (ie layer mask is not visible) = false

Thanks again

try this:

#target photoshop
s2t = stringIDToTypeID;
(r = new ActionReference()).putProperty(s2t('property'), p = s2t('hasUserMask'));
r.putEnumerated(s2t("layer"), s2t("ordinal"), s2t("targetEnum"));
if (executeActionGet(r).getBoolean(p)) {
    (r = new ActionReference()).putProperty(s2t('property'), p = s2t('name'));
    (r = new ActionReference()).putEnumerated(s2t("layer"), s2t("ordinal"), s2t("targetEnum"));
    layerName = executeActionGet(r).getString(p);
    (r = new ActionReference()).putProperty(s2t('property'), p = s2t('channelName'));
    r.putEnumerated(s2t("channel"), s2t("ordinal"), s2t("targetEnum"));
    channelName = executeActionGet(r).getString(p);
    (r = new ActionReference()).putProperty(s2t('property'), p = s2t('alphaChannelOptions'));
    r.putEnumerated(s2t("channel"), s2t("ordinal"), s2t("targetEnum"));
    alphaChannel = executeActionGet(r).hasKey(p);
    (r = new ActionReference()).putProperty(s2t('property'), p = s2t('visible'));
    r.putEnumerated(s2t("channel"), s2t("ordinal"), s2t("targetEnum"));
    channelVisible = executeActionGet(r).getBoolean(p);
    alert (channelName.indexOf(layerName) == 0 && !alphaChannel && channelVisible)
}

Fantastic!

Thank you very much jazz-y : )
