Changing the Font Color, Size & Highlighting the Text
To change the font and color of a rich text node using Aspose.Note, please follow the steps below:
- Load OneNote document to a Document class.
- Access a RichText node whose font and colors are to be changed.
- Access TextStyle.
- Set the text’s font and color.
The output of the code snippet below is shown in the figure.
Change style of the paragraph.
1String dataDir = Utils.getSharedDataDir(ChangeTextStyle.class) + "styles/";

3// Load the document into Aspose.Note
4Document document = new Document(dataDir + "Sample1.one");
5
6// Get a particular RichText node
7List<RichText> richTextNodes = document.getChildNodes(RichText.class);
8RichText richText = richTextNodes.get(0);

10for (TextStyle style : richText.getStyles()) {
11 // Set font color
12 style.setFontColor(Color.yellow);
13 // Set highlight color
14 style.setHighlight(Color.blue);
15 // Set font size
16 style.setFontSize(20);
