Alert for transparency items

Report · Jul 24, 2013

Hi Forum,

I got this from forum ,

I need a help to alert, for any type of "transparency effects" appiled to the pageItems.

Instead of referring, transparencySettings.gradientSettings,

transparencySettings.opacity,

fillTransparencySettings,

objectTransparencySettings.

etc.,

items= app.activeDocument.pageItems.everyItem().getElements();

for (i = 0; i < items.length; i++) {

if(items.transparencySettings == true) {

items.itemLayer = app.activeDocument.layers.item("items");

alert("pageitems has transparency effects")

} }

thanks for your help!

Hi Forum,

On the other side, this is not working for me...

Can you this bit...

items= app.activeDocument.pageItems.everyItem().getElements();

for (i = 0; i < items.length; i++) {

if(items.transparencySettings.dropShadowSettings == true) {

items.itemLayer = app.activeDocument.layers.item("items");

alert("pageitems has transparency effects")

} }

if in terms .applied is used, it shows error....

thanks...

Hi Forum,

also i tried with this,,

if (frameArr.transparencySettings.dropShadowSettings.blendMode === true) {

but, no result..

Do, i need to add Mode options like Multiply etc., after blendMode..

???

Hi,

Did you try to define a custom preflightProfile (enable transparency detection)?

It will alert errors if transparency (any kind) used and even report them...

If defined, your script could try to read:

app.preflightProcesses.item("myTransparencyPreflight").aggregatedResults

which is an array of strings with error descriptions.

Hi Jarek!

Acually im trying to get all the pageItems with effects==>transparency===> applied to a seperate Layer.

Sorry for my wrong request...

I need to get whatever the transparency effects applied to the pageItems to be seggregated to one Layer.

Now I got this,

items= app.activeDocument.pageItems.everyItem().getElements();

for (i = 0; i < items.length; i++) {

if(items.transparencySettings.dropShadowSettings.mode == ShadowMode.DROP) {

items.itemLayer = app.activeDocument.layers.item("items");

alert("pageitems has transparency effects")

} }

items= app.activeDocument.pageItems.everyItem().getElements();

for (i = 0; i < items.length; i++) {

if(items.transparencySettings.innerShadowSettings.applied == true) {

items.itemLayer = app.activeDocument.layers.item("items");

alert("pageitems has transparency effects")

} }

but i need to itereate for other options too. Is it possible to state in a simple conditions and not as above......

Hi,

I think preflight way is simplest (with some assumings)

Assummed:

1. there is a preflight "Transparency" defined with 1 option (transparency not allowed) enabled;

2. this preflight is activated

3. each pageItem is named originally (script adds numbers at the end of name)

If you accept above run this:

var mDoc = app.activeDocument,
mLayer = mDoc.layers.item("Transparency"),
mPref = app.preflightProfiles.item("Transparency"),
items = [], mERR, curErr, a, b, k, 
mDocItems = mDoc.allPageItems;
for (b = mDocItems.length - 1; b >=0; b --) {
          mDocItems.name = mDocItems.name.replace(/_no_\d+/, "");
          mDocItems.name += "_no_" + b;
          }
if (!mLayer.isValid) 
          mLayer = mDoc.layers.add({name: "Transparency"});
if (!mPref.isValid) {
//~           mPref = app.preflightProfiles.item(0).duplicate();
//~           mPref.name = "Transparency";
//~           mPref.preflightProfileRules.everyItem().flag = PreflightRuleFlag.RULE_IS_DISABLED;
//~           mPref.preflightProfileRules[34].flag = PreflightRuleFlag.RETURN_AS_ERROR;
          alert ("no preflight found!"); // assumed is defined by user
          exit();
          }
mERR = app.preflightProcesses[0].aggregatedResults[2];
if (mERR.length > 0) {
          for (k = 0; k < mERR.length; k++) {
                    curErr = mERR;
                    if (curErr[0]==3) items.push(curErr[1])
                    }
          }
for (a = 0; a < items.length; a ++)
          for (b = mDocItems.length - 1; b >=0; b --)
          if (items == mDocItems.name)
                    mDocItems.itemLayer = mLayer;

Just as example. Fails if some objects anchored or grouped but it could be modified, I guees.

The BOSS!!! Jarek!!!..

Just a small explanations needed...

what is : mERR = app.preflightProcesses[0].aggregatedResults[2];

&&

if (mERR.length > 0) { for (k = 0; k < mERR.length; k++) { curErr = mERR; if (curErr[0]==3) items.push(curErr[1]) // why do we use 3 and push it to 1.. what is 3 referred here..Jarek!!!!

} }

Many thanks, where i dont know that we can use preflight profiles to move the transparency.....

A new thing i have learnt from you Jarek!!!! Excellent...

Hi,

app.preflightProcesses[0].aggregatedResults[2];

aggregatedResults - this is an array of arrays of strings (you can see its content in preflight panel)

This array has 2- (no errors) or 3 elements. So 3rd element is an array with list of errors detected (aggregatedResults[2]).

Basically 1 error generates 3 kinds of info:

1. error group name

2. error description

3. name of object which causes this error

these numbers are in 1st element of mERR array, thats why code check this value. If == 3 --> 2nd element is the name of object. Script push it to array (items).

Later on those names are compared to pageItems.names and specific item is moved to "transparency" layer.

Script doesn't check if detected pageItem is anchored or grouped with others, so in this case changing layer will involve an error.

This is just to show the way...:)

enjoy

Super Jarek!!!

Have taken much effort in explaining to us (forum) and I have gained a new knowledge on this......

Excellent.... 100/100 for you....

Only one Question.. It would be great to hear, that if we can make true or false the "uses transparency" settings under preflight panel. "Transparency" == Under Images and Links..

Report · Jul 25, 2013

I Jarek!!!

I mean any possibility to check and unchek the Uses transparency options through script....

I have a little bit to create profile... but checking the options needs is not found in ESTK objects models..

var myDocument=app.activeDocument;

var profile = app.preflightProfiles.add();

profile.name = "Test";

profile.description = "Test description";

const RULE_NAME = "ADBE_PageSizeOrientation";

var rule = profile.preflightProfileRules.add(RULE_NAME);

Many thanks

Hi,

to create a preflight use:

(a list of rules indexes could be useful)

mPref = app.preflightProfiles.item(0).duplicate();
mPref.name = "Transparency";
mPref.preflightProfileRules.everyItem().flag = PreflightRuleFlag.RULE_IS_DISABLED;
mPref.preflightProfileRules[34].flag = PreflightRuleFlag.RETURN_AS_ERROR;

to activate mPref use:

app.activeDocument.preflightOptions.preflightWorkingProfile = mPref;

Jarek

PS:

1. some "helpful" or "correct" flag would be appreciated

2. activating preflight by script leads to an error I can not manage:

ID is continuing checking preflight while script is executed, so no err_report is available.

Unfortunatelly preflightProcess[0].waitForProcess() doesnt work...

...on my side only?

You have to look, if a specific transparency setting is applied.

For basically four different areas:

ContentTransparencySetting
FillTransparencySetting
StrokeTransparencySetting
TransparencySetting

The specific ones, that have a "applied" property, are:

bevelAndEmbossSettings
blendingSettings
directionalFeatherSettings
dropShadowSettings
featherSettings
gradientFeatherSettings
innerGlowSettings
innerShadowSettings
outerGlowSettings
satinSettings

Nothing more 😉

No. That's not true! It's oversimplistic.
It depends, if the values of that setting would force "transparency".

I here imply that you are basically looking after "transparency" per se…

The value 100 for opacity combined with BlendMode.NORMAL would not force "transparency"…

If you are looking for the settings of an object only, you can get a false positive (if you interpreted the results in the wrong way).

Freshly made, ordinary page items always return "MULTIPLY" for blendMode in the dropShadowSettings of the transparencySettings! That is, if you or the user did not fiddle with app or document(?) preferences or default object styles before… And there is no "transparency" applied, if you ask a user.

So, basically I think you are looking for something like "Effective Transparency".

There is no easy answer here.

Maybe it would be fruitful to script the preflight functionality and exploit the results…

Ah! Jarek gave a hint…

Long ago I wrote a couple of functions for a script: one checks if a page item is transparent and another if an effect is applied. In fact, I used the approach suggested by Uwe.

function IsTransparent(pageItem) {
    var result = false;
    var object = pageItem.transparencySettings.blendingSettings;
    var fill = pageItem.fillTransparencySettings.blendingSettings;
    var stroke = pageItem.strokeTransparencySettings.blendingSettings;
    var content = pageItem.contentTransparencySettings.blendingSettings;
    
    if (object.blendMode != BlendMode.NORMAL || object.opacity != 100) result = true;
    if (fill.blendMode != BlendMode.NORMAL || fill.opacity != 100) result = true;
    if (stroke.blendMode != BlendMode.NORMAL || stroke.opacity != 100) result = true;
    if (content.blendMode != BlendMode.NORMAL || content.opacity != 100) result = true;
    
    return result;
}
function IsEffectApplied(pageItem) {
    var currentSettings;    
    var result = false;
    var allTransparencySettings = [];
    allTransparencySettings.push(pageItem.transparencySettings);
    allTransparencySettings.push(pageItem.fillTransparencySettings);
    allTransparencySettings.push(pageItem.strokeTransparencySettings);
    allTransparencySettings.push(pageItem.contentTransparencySettings);
    
    for (var i = 0; i < allTransparencySettings.length; i++) {
        currentSettings = allTransparencySettings;
        with (currentSettings) {
            if (innerShadowSettings.applied) result = true;
            if (outerGlowSettings.applied) result = true;
            if (innerGlowSettings.applied) result = true;
            if (bevelAndEmbossSettings.applied) result = true;
            if (satinSettings.applied) result = true;
            if (gradientFeatherSettings.applied) result = true;
            if (directionalFeatherSettings.applied) result = true;
            if (dropShadowSettings.mode == ShadowMode.DROP) result = true;
            if (featherSettings.mode == FeatherMode.STANDARD) result = true;
        }
    }    
    return result;
}
