How to read Tiff images in Java

Java’s ImageIO package (built in) does not support Tiff file decoding. So either you need JAI plugin or other third party libraries to convert these files into buffered images. Support for Tiff images in both is not complete.

The third party Java libraries support only a subset of the Tiff files. (example tiling, separated planar, jpeg compression, multi page). So we decided to provide Tiff encoding and decoding support in JDeli (a complete Tiff Converter solution for developers).

Here is a simple example example to read a tiff file:

//Read Image (can also be OutputStream or byte array)
File tiffFile = new File("tiffImage.tiff"); 
BufferedImage image = JDeli.read(tiffFile);

Or you can use the JDeli TiffDecoder directly. Here is a simple example of how you can use the library to decode raw tiff bytes:

TiffDecoder decoder = new TiffDecoder(rawTiffData);
BufferedImage decodedImage = decoder.read();

or using RandomAccessFile:

RandomAccessFile raf = new RandomAccessFile("yourFileLocation","r");
TiffDecoder decoder = new TiffDecoder(raf);
BufferedImage decodedImage = decoder.read();
//insert your buffered image handling code here;
raf.close();

The code below exemplifies how to decode multi page tiff files:

 RandomAccessFile raf = new RandomAccessFile("yourFileLocation", "r");
 TiffDecoder decoder = new TiffDecoder(raf);
 for (int i = 1; i <= decoder.getPageCount(); i++) {
   BufferedImage decodedImage = decoder.read(i);
   // Insert BufferedImage handling code here
 }
 raf.close();

Technical features

The Tiff file format is actually a whole collection of possible settings. Here is the full list which JDeli supports.

Available decompression techniques:

• uncompressed
• CCITT group 3 and 4
• Deflate/Adobe Deflate
• LZW
• Packbits
• Jpeg Technote 2 ( please note: old-style jpeg compression support is not added the reason can be found here).

Tiff Decoder also supports:

• Colorspace: bilevel, grayscale, rgb, argb, cmyk, acmyk, ycbcr
• Bits Per Sample : 1 to 32
• Byte Ordering : Little and Big Endian
• Other : Single, Multi file, Tiling, Planar (Chunky, Separated), Predictor, 16,32 bit floating samples

I hope you may find it useful and make use of the features in the JDeli Image Library.

JDeli can read and write a very wide range of image formats. Here is the full list on Image file conversions supported.
