Fig. 2 is the regional artwork master that shows Taibei city,
Fig. 3 is the form that shows regional document of the present invention,
Fig. 4 shows database structure of the present invention,
Fig. 5 is the process flow diagram that shows the formation regional document program of the embodiment of the invention,
Fig. 6 is the process flow diagram that utilizes the complete electronic map system of regional document construction that shows the embodiment of the invention.
Utilize self defined area file construction electronic map system, its core is the formation of regional document, and existing is that example describes with concrete Taiwan electronic map system:
When drawing Taiwan electronic chart (Fig. 1), the administrative region at county level, city that is comprised for clear expression Taiwan, represent that the zone of these administrative regions represents with different colors, but identical color is adjacency not, now each areal map with each subordinate administrative region of expression among this figure proposes respectively with bitmap form, but its relative position is constant, then it is filled to black, and transfer monochromatic black and white bitmap to, shown in the regional artwork master (Fig. 2) in Taibei city, scan this black and white bitmap by regional document scanning formula again, form the regional document in expression zone, Taibei city, the scanning formula can adopt popular boundary scan algorithm to be write as.
The form of regional document, as shown in Figure 3, it at first is the total block data of 4 bit groups, be first of 4 bit groups always count then successively, first first Building X mark of 4 bit groups, first first Building Y mark of 4 bit groups, first last point Building X mark of 4 bit groups, first last point Building Y mark of 4 bit groups.
The piece number here refers to form the possible separation or the hollow number of partitions of an administrative region, is made of the island of many separation as Taiwan and the Penghu Archipelago (Fig. 1), and each island of these separation are all represented one; Also having a kind of situation is the hollow number of partitions, as Taipei County, Taiwan Province (Fig. 1), and Taibei city is comprised entirely by the Taipei, then to should be whole Taipei (comprising Taibei city) be one to the piece number of Taipei, Taibei city (as the hollow subregion) is one separately, because the hollow subregion occurs twice, the method that will take repeat region then to offset on the routine processes.
Each regional document of choosing is represented with corresponding filename, and deposit in the electronic map database, database structure as shown in Figure 4, wherein there is a field to represent the regional document name, the regional document name is generally identical with the map file name, only the file suffixes name is different, and is the same with the map file name, adopts the mode with the numbering expression.
The flow process of formation regional document program is drawn an electronic chart after the beginning as shown in Figure 5, and each adjacent subregion is to represent different subregion (501) with different colors; Form each corresponding bit mapping diagram (502) respectively for each sub regions; This each bit mapping diagram is filled to black, and transfers monochromatic artwork master (503) to; Utilize the regional document scanning sequence to scan each monochromatic artwork master, to form each regional document (504).
After forming regional document, just can pass through the complete electronic map system of regional document construction, the flow process of this construction program as shown in Figure 6, when system shows certain administrative region electronic chart (601), if this administrative region comprises lower floor administrative region (602), then read in the regional document of these lower floor administrative regions, by these regional documents, use one to create each regional subroutine, as standard C reatePolygnRan () api function to form each zone (603).When user's rolling mouse, then use one to judge the whether subroutine in certain zone of mouse, judge that as PtInRegion () api function mouse is whether in certain is regional (604).If, then use an anti-subroutine that in vain should the zone, instead in vain should the zone as InvertRgn () api function, or use the subroutine that a crisperding should the zone, should zone (605) as FrameRgn () api function crisperding.
