Text Markup Annotation

Text markup annotations are used to mark up text in a document. They can appear as highlights, underlines, strikeouts, or squiggly underlines applied to the page text. The type of markup is specified using the markupType property.

Use the TextMarkupAnnotation class to add text markup annotations to a PDF document.

const doc = new PdfDocument();
const page = doc.newPage();

let rc = { x: 50, y: 50, width: 200, height: 50 };
const layout = new Layout({
    runs: [{
        text: "This sample demonstrates how you can create Text markup annotation.",
        font: Font.getPdfFont(StandardPdfFont.Times),
        fontSize: 11
    }],
    maxWidth: rc.width,
    maxHeight: rc.height
});
page.context.drawLayout(layout, rc.x, rc.y);
rc = Util.inflate(rc, 15, 24)

//Create an instance of CircleAnnotation class and set its relevant properties
var textMarkupAnnot = new TextMarkupAnnotation();
textMarkupAnnot.markupType = TextMarkupType.Highlight;
textMarkupAnnot.userName = "Jaime Smith";
textMarkupAnnot.contents = "This is a Text markup annotation";
//search the text(e.g employee name) which needs to be redacted
const found = doc.findText({ text: "Text markup", matchCase: true, wholeWord: false });
textMarkupAnnot.area = [].concat(...found.map((fp) => fp.bounds));
textMarkupAnnot.color = "Yellow";
page.annotations.add(textMarkupAnnot);

const docData = doc.savePdf();
Util.saveFile("TextMarkupAnnotation.pdf", docData);
