01-05-2021 admin

This is an extended image class that supports 8-bit, 16-bit,32-bit (real) and RGB images. It also provides support for3D image stacks.

Image Plus Lite is an image manipulation tool that lets you edit, fine-tune, watermark, resize, rotate, convert and apply artistic effects to your photos. The UpWalker Lite Plus is the best investment I have made for my health and body. No more shuffling, no more walking hunched over, no more walking slowly. It glides effortlessly. The seat is like having a couple of more hands; all sorts of objects can be placed on it and rolled from room to room. Download ZEN Lite, your free copy of the powerful ZEN software. Use this free software as a viewer for your CZI files or other standard file types, or even to perform image acquisition or fundamental image analysis and processing tasks.
