Image 图片处理包装类

Chainable image processing wrapper with fluent API.

支持链式调用的图片处理包装类。

Usage Examples | 使用示例:

// Chain operations
Image.from(path)
    .resize(800, 600)
    .rotate(90)
    .watermark(TextWatermark.of("Copyright"))
    .save(outputPath);

// Get bytes
byte[] bytes = Image.from(inputStream)
    .crop(100, 100, 400, 300)
    .toBytes(ImageFormat.PNG);

Features | 主要功能:

Chainable fluent API for image operations - 可链式调用的流式图片操作 API
Resize, crop, rotate, watermark operations - 缩放、裁剪、旋转、水印操作
Save to file or convert to byte array - 保存到文件或转换为字节数组
Multiple format support (JPEG, PNG, GIF, BMP) - 多格式支持（JPEG、PNG、GIF、BMP）

Security | 安全性:

Thread-safe: No (mutable internal state) - 线程安全: 否（可变内部状态）
Null-safe: No (throws on null image) - 空值安全: 否（null 图片抛异常）

Since:

JDK 25, opencode-base-image V1.0.0
