The text formatting function of the "paper style" framework in the Java class library
In the Java programming language, the paper -style framework provides a convenient way to format and layout the text, making it easier to generate a professional appearance, document or other types of printable output.The paper style framework allows developers to define the paper style according to their needs and typesetting text and other elements in accordance with the specified style.
The paper -style framework in the Java class library mainly includes the following functions:
1. Definition of paper style: Developers can use the paper style framework to define the size, border distance, header and footer of the page.You can choose different paper sizes, such as A4, Letter, etc., and set the page border according to your needs.You can also create custom header and footestes by defining elements such as title, page number and date.
The following is a sample code to define a paper style of A4:
PaperStyle paperStyle = new PaperStyle();
paperStyle.setPageSize(PaperSize.A4);
paperStyle.setMarginTop(20);
paperStyle.setMarginBottom(20);
PaperStyle.setheadertext ("Report Title");
2. Text formatization: The paper style frame also provides a rich text formatization option.You can set the attributes such as fonts, font samples, bodies, oblique bodies, and alignment methods and spacing of text.Developers can use the paper style framework to format the text according to the specified style, and automatically page and change.
The following is a sample code to format text and output to paper:
TextFormatter textFormatter = new TextFormatter();
textFormatter.setFont(new Font("Arial", Font.BOLD, 12));
textFormatter.setAlignment(TextAlignment.CENTER);
textFormatter.setLineSpacing(1.5f);
String text = "This is a text that needs formatting."
String formattedText = textFormatter.formatText(text);
Paper paper = new Paper(paperStyle);
paper.appendText(formattedText);
paper.print();
3. Element layout: Through the paper -style framework, developers can typeset text and other elements (such as tables, charts, etc.) according to the specified layout.The position, size and spacing of the element can be set, and the relative position relationship between the elements can be defined.Through the paper -style framework, a flexible page layout can be achieved, making the generated complex documentation simple and intuitive.
The following is a sample code to define a form and layout:
Table table = new Table();
table.addcolumn ("Name", 100);
table.addcolumn ("age", 50);
table.addrow ("Zhang San", 25);
table.addrow ("Li Si", 30);
table.setLayout(new TableLayout(200, 100, 20));
table.setPosition(Position.TOP_LEFT);
Paper paper = new Paper(paperStyle);
paper.appendTable(table);
paper.print();
Summarize:
The paper -style framework in the Java class library provides a powerful text formatting and layout function, so that developers can easily generate a professional appearance, document, or other types of printed output.By defining paper style, format text, and element layout, flexible and accurate document generation can be achieved.Whether it is to generate simple text reports or complex table layout, the paper -style framework can meet the formatting and layout needs of developers.
