Introduction to the "Paper Style" framework in the Java class library
Introduction:
The Java class library provides a framework called "paper style" to create and manage printing tasks in Java applications.The paper -style framework enables developers to dynamically set and adjust the paper size, direction, and border spacing of printing tasks to achieve more flexible and customized printing functions.This framework provides a set of easy -to -use and intuitive APIs to make the paper -style management of printing tasks simple and efficient.
Features:
1. Paper size settings: The paper -style framework allows developers to set the paper size of printing tasks according to business needs.It can be achieved by specifying the width and height, or selecting a predetermined paper size (such as A4, Letter, etc.).
Example code:
Paper paper = new Paper();
Paper.Setsize (595, 842); // Set the paper size of A4, and the unit is pixel
PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();
Attributes.add (New MediaPrintableAREA (0, 0, 595, 842, Mediaprintablearea.mm)); // Set the printed area, the unit is millimeter millimeter
2. Direction settings: Developers can specify the paper direction of printing tasks to meet different needs.The optional direction includes horizontal (horizontal printing) and vertical (vertical printing).
Example code:
Paper paper = new Paper();
Paper.SetOrientation (Paperorientation.LandScape); // Set the direction of the paper as horizontal
PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();
Attributes.add (OrientationRequsted.LandScape); // Set the printing direction as horizontal
3. Border Settings: The paper style frame allows developers to define the four borders of the upper, lower, left, and right of printing tasks.This can ensure that the printing output is correctly aligned and layout on the paper.
Example code:
Paper paper = new Paper();
Paper.setImageablearea (50, 50, 495, 742); // Set the border distance of the printed area, the unit is pixel
PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();
Attributes.add (New MediaPrintableAREA (0.5F, 0.5F, 8.5F-1, 11-1, MediaprintableAREA.Inch);
Summarize:
The paper style framework provides a flexible and customized printing function for the Java application.Developers can use the paper style of the framework and managing printing tasks, including paper size, direction and border.This makes the printing output more accurate, meets the needs, and improves the reliability and user experience of printing tasks.Whether it is printing reports, invoices, or labels, the paper -style framework can meet various printing needs, providing strong tools and convenience for Java developers.
