Which attribute defines the transparency of an object?

[Raymond ZJH]

HI, Which attribute defines the transparency of an object? I want to find out from a large number of objects that use transparency...

[Monika Gause]

Independent of scripting this ...

Transparency can be applied to

- the object altogether: opacity and/or blend mode and/or pixel based effects

- the fill (there can be multiple)

- the stroke (there can be multiple)

- if there is a gradient applied, the gradient stops can have opacity settings

- in patterns the elements inside the pattern can have opacity/blend modes

- same goes for brushes

- while the stroke width is zero, the brush can still be applied to the object

- there can be an opacity mask applied

- transparency can also be applied to the group or layer the object is a part of

Thank you for your further reply!

I want to find all objects with opacity applied (< 100), regardless of what it is, pathItems,groupItems,text or others pageItems can....

opacity?

can you elaborate?

[Raymond ZJH]

Hi Carlos,

Yes, it is opacity (<100)

I want to find all objects with opacity applied (< 100), regardless of what it is, pathItems,groupItems,text or others pageItems can....

Which objects?

PathItems?

In Groups or CompoundPaths Or in Selections or in Layers/Sublayers/Document?

Fill color opacity? Or Stroke color opacity? Or Opacity in multiple colors/strokes?

In Gradients?

Unfortunately, not everything can be accessed with scripting!

For the beginning:

// select (only) one pathItem before running this snippet
var aSel = app.activeDocument.selection[0];
if (aSel.typename == "PathItem" && aSel.opacity < 100) alert(aSel.opacity);

It's pageItems in document.

I want to find all objects with opacity applied (< 100), regardless of what it is, pathItems,groupItems,text or others pageItems can....

// select (only) one pathItem before running this snippet
var aSel = app.activeDocument.selection[0];
if (aSel.typename == "PathItem" && aSel.opacity < 100) alert(aSel.opacity);

This is really a good beginning:  

aSel.opacity<100

Thank you.

My test found that it can only access the opacity of the whole object, not the opacity with details.
