A method of rendering a graphical object (e.g.,) on a page (), is disclosed. A region of the page containing the graphical object () is marked as output incompatible based on the graphical object () being output incompatible. A bounding box comprising the marked region is determined. A proportion of a number of the regions marked as output incompatible are determined to a total number of regions in the bounding box. A further region within the bounding box is marked as output incompatible to increase the determined proportion above a threshold. The graphical object in the marked region and the further marked region is converted into an output compatible graphical object if the determined proportion is above the threshold. The output compatible graphical object is rendered.

A method of rendering an image as a plurality of bands is disclosed. A plurality of edge tracking conditions for at least one of the bands is determined, the edge tracking conditions comprising waiting for at least one other band. A plurality of distinct rendering schedules is determined for the image, each rendering schedule specifying an edge tracking condition for each of the bands, the edge tracking condition for each band being selected from the corresponding plurality of edge tracking conditions for the band. A cost for a rendering schedule is determined. The rendering schedule cost is based on an edge tracking condition specified for each of the bands using a tracking cost of edges associated with the band through at least one intermediate band positioned between the band and the band specified in the edge tracking condition. The image is rendered in accordance with a selected rendering schedule, the rendering schedule being selected based on the cost determined for the rendering schedule.

Method, apparatus and system for rendering an image based on cost of tracking band edges

Disclosed is a method of applying a function to a set of data. Initially a tabular representation of the set of data is displayed, the representation comprising a plurality of columns. The data in the representation is grouped in each column based upon an order of the at least one column in the tabular representation. The method also generates a new column of data comprising a transform of existing column data contained in the tabular representation, wherein transform data within the new column depends upon a grouping context of the existing column data. Desirably the method further repositions the new column of data in the tabular representation and updates the transform data in the new column in accordance with a destination grouping context of a destination position of the new column in the tabular representation.

Method of applying a function to a data set

A method () and apparatus for generating an interface comprising a plurality of screens, on a first computer () for display by a second computer () is disclosed. A hierarchical compositing expression representing an arrangement of one or more graphical objects for a first screen of the interface is constructed. A description of the compositing expression is then transmitted to the second computer (), together with object identifiers corresponding to graphical objects for the first screen. The compositing expression is reconstructed based on the transmitted description and identifiers, where the transmitted identifiers are mapped to a description of each of the graphical objects stored within the second computer (). The first screen of said interface is then displayed according to the reconstructed compositing expression.

Client server approach for interactive updates of graphical user interfaces on intranets

A method is disclosed for activating the filling of a graphical object. The method generates, for a current scanline, a plurality of edge records associated with an edge of the object from a previously generated edge record for a previous scanline. One of these edge records comprises fractional data which defines a minimum position of the edge within the current scanline or on a border thereto with respect to a direction along said current scanline. Another of these edge records comprises fractional data which defines a maximum position of the edge within the current scanline or on a border thereto with respect to a direction along the current scanline. One of these edge records comprises fractional data which defines an exit position of the edge from the current scanline. The previously generated edge record comprises fractional data defining an exit point of the edge from the previous scanline. After the edge record generation step, the method then activates, for the current scanline, the filling of the graphical object over a run of pixels or pixel from a minimum pixel position to a maximum pixel position. The minimum pixel position is derived from rounding down a value equal to the fractional data of the edge record defining the minimum position, and the maximum pixel position is derived from rounding up a value equal to the fractional data of the edge record defining the maximum position.
