需要設置文本字段屬性以允許富文本格式。然後,您需要創建一個Span對象數組,其中包含具有所需格式的文本。
var spans = new Array();
spans[0] = new Object();
spans[0].text = "Attention:\r";
spans[0].textStyle = "bold";
spans[0].textSize = 18;
spans[1] = new Object();
spans[1].text = "Adobe Acrobat DC\r";
spans[1].textColor = color.red;
spans[1].textSize = 20;
spans[1].alignment = "center";
spans[2] = new Object();
spans[2].text = "will soon be here!";
spans[2].textColor = color.green;
spans[2].fontStyle = "italic";
spans[2].underline = true;
spans[2].alignment = "right";
// Now create the annot with spans as it's richContents
var annot = this.addAnnot({
page: 0,
type: "FreeText",
rect: [50, 50, 300, 100],
richContents: spans
});
