Abstract:
PROBLEM TO BE SOLVED: To provide a method and system for controlling access to window based applications. SOLUTION: The method collects user information including a list of events and their corresponding actions, creates a user profile file by using the user information on a workstation, starts a user access application on the work station where a user is logged on, captures the events occurring in a process of the started application, inspects them with respect to the list of the events and their corresponding actions in the user profile file, proceeds with the process execution, when the captured events are not stored in the user profile file and executes the actions corresponding to the captured events, even if the there are events which are identified in the user profile file.

Abstract:
A method to reduce the number of bits to display a pixel colour, initially represented by a three colour model (e.g. RGB octets). The method comprises reducing the bit pattern of the colour to a lower (e.g. four bit) pattern by (a) analysing the first bit, or first few bits, of each of the three bit patterns, to determine tone, (b) assigning a value to the first bit of the reduced (four) bit pattern, based on the determined tone and (c) assigning the remaining (e.g three) bits of the reduced bit pattern using a predetermined bit (e.g. the second bit) from each of the three original bit patterns. The method has particular application to remote control of computer systems, where a terminal such as 105 is used to control another terminal, 103; the speed/processing complexity of the remote control can be greatly reduced if terminal 105 displays a lower resolution version of that shown on terminal 103.
Abstract:
A method and a system for a fast and reliable color reduction from multiple bit color representations to 4 bit color representations. The method for color reduction in a computer system having a three color model for color representation of a pixel, each color being represented by a multiple bit pattern, reduces the color to a four bit value by analysing the first bit of each of said three multiple bit patterns to determine tone; assigning a value to the first bit of said four bit value, based on said determined tone; and assigning the remaining three bits of said four bit value by utilising one pre-determined bit from each of said three multiple bit patterns.
Abstract:
In remote control systems (as in many other circumstances) the color representation of a bitmap is one of the heaviest factor in term of storage occupation and speed of transmission. Often, only a limited number of colors is actually used by a bitmap, so that the bit pattern of the single pixels is bigger than what is really needed to represent all the possible different colors. With the present invention, in case the number of colors does not exceed a predetermined thresholds, a palette table containing all the colors used in the bitmap is created. The pixel representations in the bitmap are then replaced by a pointer to the corresponding entry in the palette table. This allows to reduce the total size of the bitmap. The reduced bitmap is then transmitted together with the associated palette table. The receiving computer (the controller in a remote control system) is able to rebuild the original bitmap with the help of the palette table.
