Illustrator ExtendScript设置FILL选择的不透明度

问题描述

是否可以使用javascript访问pathItem的填充不透明度?我可以访问整体不透明度，但是我想降低填充的不透明度，同时保持笔触完全不透明.

Is there any way to access a pathItem's fill opacity with javascript? I can access the overall opacity, but I want to lower the opacity of the fill while keeping the stroke fully opaque.

我在文档中找不到任何内容，也找不到其他人问这个问题.

I can't find anything in the documentation, nor can I find anyone else asking this question.

我可以像这样设置整体不透明度:

I can set the overall opacity like so:

var selection = app.activeDocument.selection;
selection[0].opacity = 50;

我尝试了所有可以想到的"fillOpacity"变体，如下所示:

I've tried every variant of "fillOpacity" that I can think of, like this:

var selection = app.activeDocument.selection;
selection[0].fillOpacity = 50;
selection[0].FillOpacity = 50;
selection[0].fill.opacity = 50;

...但是它不起作用.

...but it doesn't work.

我要解决这个错误，还是不可能?

Am I going about this wrong, or is this just not possible?

推荐答案

您无法访问它，因为即使在Illustrator中也无法正常访问它.这仅是Photoshop属性.我也检查了文档，只是为了确保.但是，您可以做的是，它将完成相同的事情:

You cannot access it, as you cannot access it normally even in illustrator. This is a Photoshop property only. I checked the documentation as well just to make sure. What you could do is this though and it would accomplish same thing:

doc = app.activeDocument;
i = 0
var selection = doc.selection[i];
var storedColor = doc.selection[i].fillColor;

//new object with only fill, we send it to back so it doesn't overlap stroke, if there is one
var newObject = app.selection[i].duplicate(doc, ElementPlacement.PLACEATEND);
//turn off fill for first object
doc.selection[i].filled = false;
i = i + 1;
newObject.stroked = false;
//apply stored color from earlier to new shape
newObject.fillColor = storedColor;
newObject.opacity = 50;
newObject.name = "50p fill";
