Embodiment
A kind of System and method for that in arbitrary graphic, limits the cursor moving range, utilize system's reading to figure coordinate, and after the arbitrfary point on the figure carried out coordinate identification, coordinate at figure limited range and limited boundary is classified, make the coordinate analysis result, and define this limited range and the limited boundary coordinate is the cursor mobile range, coordinate figure that reads with the cursor physical location and aforementioned limited range and limited boundary compare again, to specify the cursor mobile range, utilize the operation of this method, to reach the purpose that data reduction and operating speed improve.
Therefore for achieving the above object, the present invention can be illustrated by System and method for two parts.
At system aspects referring to Fig. 1 system architecture diagram of the present invention.Mainly include: database 110, recognition unit 120, reading unit 130 and comparing unit 140.Database 110 is responsible for storing figure; Recognition unit 120, the every bit that the figure that provided at database 110 is provided defines coordinate figure, and the coordinate analysis result is provided; Comparing unit 140 is responsible for relatively cursor coordinates value and coordinate analysis result, to send object information; Reading unit 130 is in order to provide the cursor coordinates value; Wherein utilize object information to limit the moving range of cursor.
When the user uses when of the present invention, the picture that system is at first browsed at the user, in database 110, obtain the figure and the demonstration that meet this picture, after graphic presentation, recognition unit 120 promptly defines a coordinate figure at the every bit of this figure, and analyze this figure and whether have the localized area, then provide a coordinate analysis result if having, and this coordinate analysis result is mainly in order to provide the foundation that limits the cursor moving range.
After the coordinate analysis result sets up, as user during in this graphic picture operation, the coordinate figure of cursor position at any time can via reading unit 130 read and input system in, the coordinate figure that is transfused to is compared unit 140 and receives, and compare analysis with the coordinate analysis result who has before made, if the present position of this cursor exists among this coordinate analysis result, promptly control this cursor and in this limited range, move; If the present position of this cursor is in this coordinate analysis result, be about to move in the border that this cursor is controlled at this limited range.The cursor coordinates value that above-mentioned reading unit 130 is obtained, can utilize a mouse or a trace ball to provide, also can utilize a light pen or touch panel to provide, more can utilize a recreation light rifle or any device of cursor coordinates value that can provide to provide.
After the flow process of the basic framework of having introduced system aspects and each unit data running, then state method of operating of the present invention by Fig. 2 cursor comparison of the present invention process flow diagram.
At first the user is opening after any one limits picture, and coordinate figure (step 210) can preferentially be distinguished by system, to present unlatching and the graphic picture in browsing, carries out the coordinate of every bit in the picture and distinguishes; In having distinguished picture, after the coordinate of every bit, read the range information and the boundary information (step 220) of figure immediately, to determine the qualification moving range of this figure; Then according to the previous coordinate figure that obtains, defining this range information is first data (step 230); And defining this boundary information is second data (step 240); At this coordinate figure of arrangement and range information and boundary information, obtain a coordinate analysis result (step 250) at last.
When user's manipulable cursor, the coordinate of cursor position is promptly by providing the device of cursor coordinates value, input to one by one in the reading unit 130, shown in Fig. 3 judgement cursor position of the present invention process flow diagram, system is after reading the coordinate figure (step 310) of cursor, and the coordinate information that is about to obtain sends comparing unit 140 to; Comparing unit 140 promptly according to coordinate information that obtains and the coordinate analysis result (step 320) who reads graphic making at the beginning, compares coordinate figure and the range information of figure and the action of boundary information (step 330) of cursor at this moment; Judge whether this cursor is in movably scope (step 340); When this coordinate figure was in this coordinate analysis result, promptly instructs cursor was in mobile range (step 350); When this coordinate figure was not in this coordinate analysis result, promptly instructs cursor was moved the border (step 360) to mobile range.
Then operating process of the present invention is described by an embodiment, at first system is after reading a figure, except (polygon as Fig. 4 embodiment of the invention limits shown in the figure) this figure is presented, more the every bit in this figure is carried out the affirmation and the editor of coordinate, and make coordinate analysis result as Fig. 5 embodiment of the invention, afterwards when user's operational light timestamp, whenever read a coordinate figure and be about to this coordinate figure and this coordinate analysis result comparison, if this coordinate figure exists, represent that promptly this cursor can move in this coordinate points in this coordinate analysis result; If this coordinate figure when not existing, represents that promptly this cursor can not move in this coordinate points in this coordinate analysis result, and this cursor moved to the boundary of limited range move.
Though the present invention is open with aforesaid preferred embodiment; right its is not that any those of ordinary skills are not breaking away from the spirit and scope of the invention in order to qualification the present invention; change and retouching when doing some, therefore scope of patent protection of the present invention is as the criterion with claim.
