AFAIK 无法通过 Apps 脚本或 API 实现
我尝试检查 Apps 脚本中所有可能的属性，但在我修改弧的扫描时没有任何改变。然后我尝试检查slides API
最多给了我这些参数：

我手动更改了弧的扫描，除了revisionId之外，其他属性都没有变化。
因此，在这种情况下，鉴于我找不到任何现有的功能请求，您可能希望使用以下模板自己提交一个：

说明无法通过 API 或 Apps 脚本修改弧的扫描。确保添加尽可能多的信息和理由，以增加引起注意的机会。
解决方法
最简单的方法可能是制作您认为会使用的进度条，然后将它们保存在驱动器中，并在需要时插入它们。也就是说，对于您想要的每个进度阶段，可能有 10 张图片。
另外，还有一种使用画布 API 的稍微复杂的方法。由于您可以通过getUi 在侧边栏中加载 HTML，因此您还可以使用 canvas API 创建图像，同样您可以从中创建图像并将它们传递给您的演示文稿。
这是一个演示：
代码.gs
function test(){
// This creates the HTML output from the file arc-creator.html
let html = HtmlService.createHtmlOutputFromFile('arc-creator')
// This uses the html to load the sidebar
SlidesApp.getUi().showSidebar(html)
}
// This function will be called from the HTML once the canvas has finished drawing.
function addToPresentation(dataURL){
let slide = SlidesApp.getActivePresentation().getSlides()[0]
// Convert the data Url to png and add to Presentation
var type = (dataURL.split(";")[0]).replace('data:','');
var img = Utilities.base64Decode(dataURL.split(",")[1]);
var blob = Utilities.newBlob(img, type, "image.png");
slide.insertImage(blob);
}
arc-creator.html
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<body>
<canvas id="canvas" width="200" height="200"></canvas>
</body>
<script>
// This is the function that creates a data URL image
// The argument is the percentage complete of the progress bar
function createProgressArc(number){
// ID the canvas element and initialize the context
var canvas = document.getElementById('canvas');
var context = canvas.getContext('2d');
// Some utility variables
var cw=context.canvas.width/2;
var ch=context.canvas.height/2;
// Drawing background
context.clearRect(0,0,200,200);
// Drawing first circle
context.beginPath();
context.arc(cw,ch,50,0,2*Math.PI);
context.fillStyle='#FFF';
context.fill();
context.strokeStyle='#e7f2ba';
context.lineWidth = 10;
context.stroke();
// Drawing arc
context.fillStyle='#000';
context.strokeStyle='#b3cf3c';
context.lineWidth=10;
context.beginPath();
let progress = (2 * Math.PI) * (number/100)
context.arc(cw,ch,50,0,progress);
context.stroke();
// Converting to data URL
var dataURL = canvas.toDataURL("image/png");
return dataURL;
}
let dataURL = createProgressArc(75)
// Here is where the resulting image is sent back to the Presentation as a data URL
google.script.run.addToPresentation(dataURL)
</script>
</html>
运行此程序将在 UI 中打开一个侧边栏，绘制图像，然后将图像添加到第一张幻灯片。
此方法的缺点是您需要打开 UI，否则它不会运行绘制弧所需的 JavaScript。
