We can export a JPEG using ExportOptionsJPEG() — but it allows to set only quality, not a resolution.

We can use ImageCaptureOptions() instead to set a resolution — but it won’t allow to set a quality, because seems to be designed for PNG (and substituting a format to JPG gives questionable results).

We need to be able to export JPEG images, controlling both quality and resolution, without using app.doScript() trick — it fails on Cyrillic folder names.

Commands:
//menu Other Object\Isolate Selected Object
app.executeMenuCommand('enterFocus');

//menu Other Object\Exit Isolation Mode
app.executeMenuCommand('exitFocus');

Return error:
an Illustrator error occurred: 1346458189 ('PARM').

This applies not only to isolation, but also to some other commands.

Create a text object, type some text, keep it selected and run the script:

activeDocument.textFrames[0].paragraphs[0].paragraphAttributes.firstLineIndent = 20;
alert(activeDocument.textFrames[0].paragraphs[0].paragraphAttributes.firstLineIndent);

activeDocument.textFrames[0].paragraphs[0].paragraphAttributes.firstLineIndent = 0;
alert(activeDocument.textFrames[0].paragraphs[0].paragraphAttributes.firstLineIndent);

You have two alerts saying 20, while the second one should show and actually set the first line indent value to 0 — and it does not.

There is no way to access the opacity of a textRange. This TextFrame has 100% opacity, but it contains two textRanges, one of which is at 50% opacity. I don't believe that there is a way to make everything 100% opaque from javascript.

In CC2019, at least two notifiers should result from renaming art: kAIArtPropertiesChangedNotifier & kAIArtObjectsChangedNotifier, but neither is sent.

I have dashed lines in my drawing and want to align dashes to corners and path ends. No problem in the Illustrator stroke menu. There are two buttons with dashed lines on it. But there is no script command to do this.

Please add script command for adjust dashes.

Currently this is producing an error in CC2018 Illustrator on Mac

var newFile = new File('/tmp/sample.rtf');
app.activeDocument.importFile(newFile, false);

Works correctly in CC2017.

importFile() worked fine in CC2017, now in CC2018 it throws an "Illegal Argument" error.

here's a small JavaScript to test. Open any document or create a blank file before running the script

var f = File('c:/temp/Example File.pdf'); // to test, add a path to a valid file in your system

var idoc = app.activeDocument; // have any document open

idoc.importFile(f, false);

We have an action that works, when launched form the Actions panel.
Operations are simple:
1. Copy
2. Deselect All
3. Paste in Front
4. Join
5. Join
It is designed to create a new closed shape from two segments from different shapes.

However, when we call this exact action from a script with a app.doScript, it doesn’t work, an error message 'The object "Join" is not currently available' is displayed.

Please see the video.

説明

ExtendScript経由で［スクリーン用に書き出し］を実行すると動作が遅くなり，動いていないように見えます（実際は動いていて長い時間待てば終わる）。その間レインボーカーソルが出ています。

JPEGを書き出すときに顕著です。書き出す画像がある程度大きいと，プログレスバーが99%くらいになった後ほとんど進みません。CPU使用率は100%前後になります。

例：1700x1000pxのアートボード8枚を300ppiで書き出すとき，かかる時間は228.175秒（できたJPEGの重さは1点につき2.9MB）

同じ条件の書き出しをGUIから手動で実行すると，すぐに終わります。

例：1700x1000pxのアートボード8枚を300ppiで書き出すとき，かかる時間は2秒くらい（できたJPEGの重さは1点につき1.8MB）

PNG24は手動よりは遅いですが，JPEG程大きく影響しません。CPU使用率は160%前後でした。

例：1700x1000pxのアートボード8枚を300ppiで書き出すとき，かかる時間は57.745秒

次の条件で起こります。
* 少なくともIllustrator 2020〜2022(24.3.0〜26.0.2)
* 少なくともmacOS Monterey 12.0.1(Apple Silicon) / Big Sur 11.6(Apple Silicon)の2環境
* 少なくともMacBook Air(Apple Silicon, 16GBメモリ) / iMac(Apple Silicon, メモリ不明)の2機種
* ExtendScriptのDocument.exportForScreens経由で実行
* オプションJPG 100，300ppi(アートボードサイズは1700x1000px)

次の条件では起こりません。
* オプションをJPG 100，72ppiにしたとき
* オプションをPNG24，300ppiにしたとき
* GUIから手動で実行したとき

次の項目はあまり影響しないようです。
* IllustratorをRosettaで起動するかどうか。Rosettaにしたらさらに遅くなる
* アートボード上のアイテムを単純なデータにすること。四角いパスとグラデーションだけでも遅くなる

期待する動作

ExtendScript経由で［スクリーン用に書き出し］を実行したとき，GUI経由で行うのと同じくらい速く動きます。

adjusting one gradient causes changes to unrelated gradients on same document.

Running a script to set the justification of text works perfectly for left and right, but no longer works for center. Putting the example script given in the latest Illustrator CC Scripting Guide, page 122, into a Script Editor visually compiles centre differently to left and right and only works if you remove or comment out the line justifying to center.

As far as I know there is no possible way to execute an Extendscript via the C++ API.
In InDesign we can do so by providing the script as a string and fetching simple output results.

Our customers can customize our Plugins by providing their own script in our custom scripting language. Unfortunately our language does not cover all use cases and needs to be constantly expanded. With support for Extendscript/Javascript execution from the C++ API we could circumvent the problem and give the users a lot of flexibility and power.

The AIAddToolData struct is still using char* for the title & tooltip members. I know it does some kind of localization, but that's really archaic when the rest of the SDK uses ai::unicode.

The Samples included with the SDK cannot currently be compiled on Windows unless MFC was installed as part of the Visual Studio installation procedure.

Making the Samples requires two small things:

1. Add the following include below the SDKDef.h include in VersionInfo.rc

include "verrsrc.h"

1. Change the "afxres.h" include in the .rc of all plugins to instead include "winuser.h"

Doing so will make MFC optional, and not required; ultimately, including 'afxres.h' is including the two headers outlined above so it's just introducing an unnecessary middle man who can be safely bypassed.
