SetSpacingLine

Sets the paragraph line spacing. If the value of the sLineRule parameter is either "atLeast" or "exact", then the value of nLine will be interpreted as twentieths of a point. If the value of the sLineRule parameter is "auto", then the value of the nLine parameter will be interpreted as 240ths of a line.

Inherited from ApiParaPr.SetSpacingLine.

Example

Adjust the spacing between lines of text in a paragraph in a presentation.

// How do I change the line height in a presentation?

// Set the vertical distance between text lines using paragraph properties 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();
const paragraph = docContent.GetElement(0);
const paraPr = paragraph.GetParaPr();
paraPr.SetSpacingLine(3 * 240, "auto");
paragraph.AddText("Paragraph 1. Spacing: 3 times of a common paragraph line spacing.");
paragraph.AddLineBreak();
paragraph.AddText("These sentences are used to add lines for demonstrative purposes. ");
paragraph.AddText("These sentences are used to add lines for demonstrative purposes. ");
paragraph.AddText("These sentences are used to add lines for demonstrative purposes. ");
slide.AddObject(shape);
