Disclosed is a method of orientating a space curve having two endpoints. The method comprises selecting a desired direction and then generating a first vector having a direction which is same as the selected desired direction. At least one second vector is then generated, each said second vector having a corresponding direction indicative of a corresponding characteristic of the space curve. The first and second vectors are compared so as to determine a direction of the space curve, wherein the determined direction of the space curve is along the curve from the first endpoint to the second endpoint and which is closest to the selected desired direction. The direction of the space curve is then oriented in accordance with the determined direction.

The kerning of text modified in various ways is disclosed. The text can be modified by distortion or perturbation. In one way no unmodified text character pair kerning distance is stored. The kerning distance (x) is calculated as typesetting proceeds. In another way, an unmodified text character pair kerning distance (k ) is used but modified by the amplitude of the text perturbing functions.

The method generates a skeleton of a polygon by selecting a line segment or concave vertex ( ) of the polygon and comparing it against the other line segments( ) in turn. The method determines ( ), when comparing a selected line segment or concave vertex i with another line segment j, any significant parameter value associated with a point on selected line segment, where the locus(i,j) at that parameter value describes the skeleton.

Methods and apparatus for processing an image is disclosed. First an output value of a first current pixel (in ), which is not at an edge of the image, is determined using a first influence value (W ) for a first current pixel which equals a first sum, over a first set of pixels, of the product of a pixel weight value and a corresponding pixel value, where the pixel weight value is substantially equal to a weight factor (X, Z) raised to the power (i) of the distance of the pixel from the first current pixel. An output value for a second current pixel (in ), is determined using a second influence value (W ) determined as either a product of a weight value reducing factor (X) and the first influence value, or a product of weight value reducing factor and the sum of the first influence value and a value for the first current pixel, where the second influence value equals a second sum over a second set of pixels of the product of a pixel weight value and a corresponding pixel value, and where each pixel weight value is substantially equal to a weight factor raised to the power of the distance of the pixel from the second current pixel.

Geometrically reducing influence halftoning

An undirected graph is generated based on a set of finite n-dimensional space curves. One or more traversal modulations are selected and a directed graph is created by traversing the edges of the undirected graph and determining a direction, either a forward direction or a reverse direction, for each edge in accordance with the selected traversal modulations. The method then re-orientates the set of finite n-dimensional space curves in accordance with the directed graph.
