libCZI

What

libCZI is an Open Source Cross-Platform C++ library to read and write CZI.

Why

libCZI is a library intended for providing read and write access to CZI featuring:

• reading subblocks and get the content as a bitmap
• reading subblocks which are compressed with JPEG-XR or zstd
• works with tiled images and pyramid images
• composing multi-channel images with tinting and applying a gradation curve
• access metadata
• writing subblocks and metadata

In a nutshell, it offers (almost...) the same functionality as the 2D-Viewer in ZEN - in terms of composing the image (including display-settings) and managing the data found in a CZI-file.
