Interface RasterOperation

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface RasterOperation
Raster Operation Raster 操作函数接口

Functional interface for Raster-based image operations with exception handling. Zero-AWT counterpart of ImageOperation.

基于 Raster 的图片操作函数接口，支持异常处理。 ImageOperation 的零 AWT 对应物。

Usage Examples | 使用示例:

RasterOperation op = raster -> ThresholdOp.binarize(raster, 128);
Raster result = op.apply(sourceRaster);

// Chain operations
RasterOperation chain = op1.andThen(op2).andThen(op3);

Features | 主要功能:

  • Functional interface for raster transformations - Raster 变换的函数接口
  • Chainable via andThen composition - 通过 andThen 组合可链式调用
  • Exception-aware apply method - 支持异常的 apply 方法

Security | 安全性:

  • Thread-safe: Yes (stateless functional interface) - 线程安全: 是（无状态函数接口）
  • Null-safe: No (throws on null raster) - 空值安全: 否（null raster 抛异常）
