示例
在演示文稿中设置段落之间的行距。
// How do I adjust the spacing between lines of text in a presentation?
// Apply different line spacing values to paragraphs in a presentation.
const presentation = Api.GetPresentation();
const slide = presentation.GetSlideByIndex(0);
slide.RemoveAllObjects();
const gs1 = Api.CreateGradientStop(Api.RGB(255, 213, 191), 0);
const gs2 = Api.CreateGradientStop(Api.RGB(255, 111, 61), 100000);
const fill = Api.CreateRadialGradientFill([gs1, gs2]);
const stroke = Api.CreateStroke(0, Api.CreateNoFill());
const shape = Api.CreateShape("flowChartMagneticTape", 300 * 36000, 130 * 36000, fill, stroke);
shape.SetPosition(608400, 1267200);
const docContent = shape.GetDocContent();
let paragraph = docContent.GetElement(0);
paragraph.SetSpacingLine(2 * 240, "auto");
paragraph.AddText("Paragraph 1. Spacing: 2 times of a common paragraph line spacing.");
paragraph.AddLineBreak();
paragraph.AddText("These sentences are used to add lines for demonstrative purposes. ");
