Selecting Flo' in Photoshop's Filters menu launches the Flo technology's interactive image distortion environment, where the user can apply plasticity tools at any resolution, without degrading the original image quality. Each operation is remembered as a tree of instructions and is fully editable, even after the file is saved. Once you achieve the desired effect, the image is rendered at high quality and sent back to Photoshop. Metaflo' 2.0 and Movieflo' 2.0's Region of Change technology, first introduced in Flo' 2.0 for Macintosh and Windows, provides powerful new distortion editing capabilities, for enhanced control of the Freeform Plasticity engine. Now the user can define one or more simultaneous areas, applies distortions, preview the results, and then continue to edit the regions.
Users can even change tools while continuing to edit their defined regions.
Once the user defined regions are edited, the user can draw an outer boundary to contain the effect within a specific region beyond which nothing changes. ROC curves are used for distortions and masks in Metaflo' 2.0 and Movieflo 2.0. Like pixelated region tools you find in Adobe Photoshop and other programs, these define regions that can have holes and sections can be added or subtracted. Unlike pixelated region tools, ROC borders are editable smooth curves and can be edited at any time. Alpha Channel TIFF and PICT still images.
