To get a histogram using UXP Scripting

[やわらかうなぎ]

To get a histogram of the red channel using ExtendScript Toolkit, I can do the following.

var h = activeDocument.height;
activeDocument.selection.select([[0,0],[0,h],[1,h],[1,0]]);
var data = activeDocument.channels[0].histogram;

However, using the UXP Developer Tools, I get an error when I do the following.

const { app } = require(“photoshop”);
const doc = app.activeDocument;
doc.selection.selectColumn(0);
console.log(doc.channels[0].histogram);

This link has a property to get the histogram, what am I doing wrong?

Photoshop version is 26.0.0 and all channels are shown.

UXP Developer Tools version is 2.0.2.3.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

Thanks for the reply. I figured out how to use it.

確かにエラーが起きますし、ほかの開発者からも同様の報告があります。batchPlay経由なら取得できるようです。

• Getting single color channels histogram values not working?

ただし、普通にやると言語ごとにredの名前の部分をローカライズして取得しなければいけません。そんなときはこちらのindexでチャンネルを取得する方法を参考にしてください。

• Possible bug when getting document channels if PS is not in English?

ちなみに、UXPの開発者は Adobe Creative Cloud Developer Forums のほうに集まっていますので、次回からはそちらへの投稿がおすすめです。

It does indeed throw an error, and other developers have reported the same. Seems to be possible to get it via batchPlay.

• Getting single color channels histogram values not working?

However, if you do it normally, you have to localize the red name part for each language to get it. In such a case, please refer to this method of getting channels by index.

• Possible bug when getting document channels if PS is not in English?

By the way, UXP developers gather at Adobe Creative Cloud Developer Forums, so it is recommended to post there from next time.

Thanks for the reply. I understood it as a bug. I will post to that Forum in the future.
I am not familiar with this site, so thanks for letting me know.
