Java TIFF Reader

JDeli includes a TIFF Reader to read TIFF images into Java. The TIFF Decoder is written in 100% Java with no dependencies.

Key information:

• 100% Java solution. No dlls or dependencies on native code
• Compression: CCITT 3,4, Pack bit, LZW, Adobe Deflate, JPEG technote2 and Deflate
• 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

Quick start:

JDeli can automatically detect the file type and will use the TIFF File Reader

BufferedImage image = JDeli.read(tiffImageFile);

or

TiffDecoder decoder = new TiffDecoder();
BufferedImage image = decoder.read(tiffData);

See the full Javadoc.

Performance comparisons:

These figures were generated using jmh (as documented on our blog) with a standard set of images (also documented). They should be easy to replicate if you wish to validate, the code is on GitHub.

The higher the number, the better.

Mode: Throughput Count: 25 Units: ops/s

Tested on 2020 13inch M1 MacBook Pro using JDK 18.0.1.1

Read Multi Image tiff files

This needs the TiffDecoder class

File file = new File("/path/to/file");
TiffDecoder dec = new TiffDecoder();
int totalImages = dec.getImageCount(file);
for (int i = 0; i <= totalImages; i++) {
   BufferedImage image = dec.read(i , file); // i is the image number
   // Insert BufferedImage handling code here
}
