java.lang.Object
java.lang.Enum<Orientation>
cloud.opencode.base.pdf.document.Orientation
All Implemented Interfaces:
Serializable, Comparable<Orientation>, Constable
public enum Orientation extends Enum<Orientation>
Page Orientation - Portrait or Landscape 页面方向 - 纵向或横向

Features | 主要功能:

  • Portrait and landscape orientation constants - 纵向和横向方向常量
  • Dimension adjustment based on orientation - 根据方向调整尺寸

Usage Examples | 使用示例:

Orientation orient = Orientation.LANDSCAPE;
float[] dims = orient.apply(595, 842); // swaps to [842, 595]

Security | 安全性:

  • Thread-safe: Yes — immutable enum - 线程安全: 是 — 不可变枚举
  • Null-safe: N/A — enum values are never null - 空值安全: 不适用 — 枚举值不会为空
Since:
JDK 25, opencode-base-pdf V1.0.0
