Definitions

  • Figures 5A and 5B demonstrate intersection of regions on canvas and corresponding structure in database
  • Figures 8A and 8B are illustrative figures for procedure of determining and deleting passive operations in database
  • Device Context is a structure that stores information needed when a program written for OS Windows must display output to a device such as screen or printer.
  • OS Windows utilizes Device Contexts in order to provide device-independent drawing.
  • OS Windows maintains two types of drawing surfaces, which are referenced in Device Context: bitmaps in memory (memory drawing surface) and screen drawing surface. In the following description, these drawing surfaces are called canvases.
  • API functions which has references to two or more canvases. These API functions take pixel data from one or more canvases - source canvases, combine this data and after that utilize resulting data in order to change pixels on destination canvas.
  • API function BitBlt which has references to source and destination Device Contexts in its parameters is an example of such function.
  • Source canvases of passive operations may be present on source canvases of passive operations. These regions previously had links with source regions of passive operations. As soon as these links are destroyed on step 132, algorithm must proceed further. Source canvases of each passive operation, in turn, is set as current 134 and algorithm for these canvases is proceeded 136 with the same steps of determining and deleting of passive operations on these canvases.

Abstract

La présente invention concerne un procédé permettant la mise en place et l'enregistrement d'un ensemble d'opérations, les opérations ne contribuant pas à la formation de l'image sur l'écran étant effacées. Ce procédé donne la possibilité de réduire le nombre total d'opérations enregistrées dans une mémoire tampon. Cette invention concerne également une application arbitraire (2) qui envoie des appels API au système d'exploitation (4) afin de représenter les données sur l'écran (6). Au cours du processus de représentation, ces appels sont interceptés par la fonction (8) de l'application utilisée pour l'exécution du procédé de la présente invention.
