Endrov is both a library and an imaging program. The design has made strong emphasis on separating GUI code from data types, filters and other data processing plugins. The idea is that the program can be used for most daily use or prototyping, and for bigger batch processing or integration, the code is invoked as a library.
As a program, Endrov can do what you expect from normal image processing software. It is meant to be hackable; integrating new editing tools, windows and data types is meant to be simple. The main features that set it apart from other imaging software is that it can handle additional dimensions (XYZ, time, channel) which is needed for more serious microscopy. Filters can also be used without being directly applied, and can be composed into filter sequences. Data (for example derived from analysis) is stored together with the images.
The native image format is OST but most common formats are supported.
