Technology Overview riteShape® is our patent protected shape and chart recognition technology. riteShape SDK is a tool for developers looking to add shape recognition and correction to their pen applications. riteShape recognizes, improves, and aligns geometrical shapes or polylines created in freehand drawings. The riteShape engine allows developers to expand the capabilities of their software for Tablet PC, PDAs and other pen-enabled devices with perfect circles, squares, triangles, arrows, and complete charts, built directly from freehand inputs.

Features

• Automatic smoothing of ovals, rectangles, triangles, arrows, and arbitrary "polylines"
• Automatic alignment to standard coordinates
• Adjustable recognition of strict shapes (circles vs. ovals, squares vs. rectangles, etc.)
• Adjustable control over self-intersecting lines
• Automatic shape and connector alignment
  • When two or more circles and rectangles seem to be positioned along a horizontal or vertical line, their size and center positions are adjusted. 
  • If some shapes are connected with arrows or lines, the positions of the connectors' ends are adjusted to perfectly fit the boundaries of the shapes 
• Adjustment of concentric shapes
  • Intelligent recognition of concentric shapes, such as a circle or a rectangle that is drawn inside another circle or rectangle around approximately the same point
• Adjustment of grid and adjacent polygons
  • To achieve a tablet-like grid, the ends of lines are adjusted when straight lines are drawn. Additionally, if two separate polygons appear to have a common side, the close sides are combined
