Active Pixels 4 new undo engine
As I would like very long time ago, I finally wrote a new undo engine for Active Pixels. You can see the results on the chart. Figuratively speaking, it can be called “undo engine of the fourth generation.” It saves a lot of memory, especially noticeable when working with large photographs. Previously, even simple actions with large images required very large amounts of memory, now everything works much faster and more economical. In earlier versions undo engine is constantly modified, but the idea was unchanged. Now it works perfectly on another mechanism. In addition, if the rate of return of the image suddenly you not enough – you can increase the levels of cache and get the maximum speed, but with higher memory. Finally I can say that the active pixels undo engine does not yield to the best paid graphical editors and may be compared with them.
