TiffImages.jl

Pure-Julia TIFF reader and writer with a focus on correctness 🧐

TIFF (Tagged Image File Format) is a notoriously flexible file format that is very difficult to support properly so why not just link libtiff and call it a day? Because Julia developers are greedy. I wanted to design a clean, minimal, and standards-compliant TIFF reader and writer that can have the speed and compliance of libtiff while adding modern features like streaming, out-of-memory support, and fancy color support. I wanted to design it to be extensible such that packages like OMETIFF.jl can hook right in with minimal overhead. I wanted to leverage the wonderful Julia Arrays ecosystem to do as much lazily and flexibly as possible.

Features

TiffImages.jl supports:

• The TIFF 6.0 baseline spec
• Thorough testing
• HDR images stored as 32bit or 64bit floats
• BigTIFF standard (TIFFs larger than 4 GB)
• Memory-mapped and lazy loading/writing
• Arbitrary bit depths (e.g. 12 or 14 bit cameras)
• Common compression algorithms like LZW and Packbits
