A runtime patcher to introduce extension points into the original ImageJ (1.x). This project offers extension points for use with ImageJ2 and it also offers limited support for headless operations.

/**
* Assorted legacy patches / extension points for use in the legacy mode.
*
*
* The Fiji distribution of ImageJ accumulated patches and extensions to ImageJ
* 1.x over the years.
*
*
*
* However, there was a lot of overlap with the ImageJ2 project, so it was
* decided to focus Fiji more on the life-science specific part and move all the
* parts that are of more general use into ImageJ2. That way, it is pretty
* clear-cut what goes into Fiji and what goes into ImageJ2.
*
*
*
* This class contains the extension points (such as being able to override the
* macro editor) ported from Fiji as well as the code for runtime patching
* ImageJ 1.x needed both for the extension points and for more backwards
* compatibility than ImageJ 1.x wanted to provide (e.g. when public methods or
* classes that were used by Fiji plugins were removed all of a sudden, without
* being deprecated first).
*
*
*
* The code in this class is only used in the legacy mode.
