如何使用Java磁贴读取TIFF文件? [英] How to read a TIFF file by tiles with Java?

问题描述

假设我有一个非常大的TIFF图像作为输入.由于必须遵守的内存规格，我无法完全加载该映像.因此，以下不是一种选择:

Let's say I have a very large TIFF image as input. I am not able to load this image entirely because of memory specification I must comply with. So the following is not an option :

BufferedImage data = ImageIO.read(image);

有没有Java库允许读取图像的特定部分而不缓冲整个图像?还是从流中获取TIFF切片的某些方法?

Is there any Java library allowing to read a specific part of the image without buffering the whole image ? Or some ways to get TIFF tiles from a stream ?

推荐答案

ImageIO可以为您提供Tiff的ImageReader，然后您可以使用

ImageIO can provide you an ImageReader for Tiff, and then you can use readTile. ImageIO has several getImageReadersBy... methods.

我不知道ImageIO是否支持tiff，但是ImageIO使用Java SPI，因此可以插入ImageReaders和ImageWriters.

I am not aware whether tiff is supported by ImageIO, but ImageIO uses java SPI so one may plug-in ImageReaders and ImageWriters.

实际上，这是read的快捷方式，其中ImageReadParam配置为图块.

In fact this is a short-cut for read with ImageReadParam configured for tiles.

从不使用图块，但看到先前的答案，我想指出此选项.
