在Java中获取TIFF图像的像素值 [英] Getting the pixel value of a TIFF image in Java

问题描述

ImageIO 包不适用于 .tif 图片，我无法创建BufferedImage（Class I'从 .tif 文件中更熟悉）。

The ImageIO package doesn't work with .tif images and I cannot create a BufferedImage (Class I'm more familiar with) from a .tif file.

如何轻松获取TIFF的像素值用Java形象？我怎么能快速完成？

How do I easily get the pixel value of a TIFF image in Java? How can I do it FAST?

我对图像处理没有经验，我会非常感谢一些示例代码！

I'm not experienced with image processing and some sample code would be greatly appreciated!

谢谢！

推荐答案

您将需要Java Advanced Imaging API： JAI 以便使用TIFF图像。

You will need the Java Advanced Imaging API: JAI in order to work with TIFF images.

来自JAI API描述：

From the JAI API description:

TIFF

除基线规格外，编码器和解码器还支持PackBits，修改过的Huffman和CCITT双层编码（传真），JPEG-in-TIFF（根据TIFF技术说明＃2）和DEFLATE压缩方案，可以处理具有16位和32位整数样本和32位浮点样本的图像，并且可以读取和写入所有支持的数据类型的平铺图像。解码器还可以解压缩LZW压缩图像。

In addition to the baseline specification, the encoder and decoder support PackBits, modified Huffman and CCITT bilevel encodings (fax), JPEG-in-TIFF (per TIFF Technical Note #2), and DEFLATE compression schemes, can handle images with 16- and 32-bit integral samples and 32-bit floating point samples, and can read and write tiled images of all supported data types. The decoder in addition can decompress LZW-compressed imagery.

将来可能会解决其他功能。

Additional features may be addressed in the future.

通过使用带有TIFF运算符的page参数，可以最轻松地加载多页TIFF文件的单页，该运算符记录在javax.media.jai.operator.TIFFDescriptor的类注释中。此处包含一个代码示例，用于显示使用辅助编解码器类直接加载多页TIFF文件的单页的方法。

A single page of a multi-page TIFF file may loaded most easily by using the page parameter with the "TIFF" operator which is documented in the class comments of javax.media.jai.operator.TIFFDescriptor. A code sample is included here to show a means of loading a single page of a multi-page TIFF file using the ancillary codec classes directly.
