LEADTOOLS Image Processing
Region of interest
LEADTOOLS region of interest specifies an area rather than the entire image to process or display.
Regions can be defined as any combination of shapes including rectangles, ellipses, rounded-rectangles, freehand shapes, polygons, curves and Bezier curves. LEADTOOLS also lets you select regions based on the color of pixels within the image. You can select all pixels in an image having a specific color, or you can select contiguous regions starting with a seed pixel and a color-match threshold by using the "Magic Wand". Complex regions can be built using a variety of boolean operations on simpler regions, including union, intersection, xor and inverse.
Additionally, LEADTOOLS includes region transformations that are not found or difficult in Windows including resizing and rotating.
