Description
Technical field
The present invention relates to a kind of reconstructing method, particularly relate to a kind of CAD electronic data Chinese version signal reconstruct method based on locus.
Background technology
Computer-aided design (CAD-ComputerAidedDesign) refers to and utilizes computer and graphics device thereof to help designer to be designed work.Text is the significant data type in CAD electronic data.Can express figure by word, symbol fails the design idea that expresses clearly, is the important supplement to design object attribute information.In prior art, the mode typically via manual reading of drawings understands the text in CAD electronic data.Sharing at cad data and automatically extract field with text, mainly realize CAD text object and to extended formatting conversion or extract independent text chunk content, again through manually carrying out understanding and recombinating, method is comparatively laborious, inefficient.
Summary of the invention
In order to solve the weak point existing for above-mentioned technology, the invention provides a kind of CAD electronic data Chinese version signal reconstruct method based on locus, CAD electronic data will be automatically reconstructed into the text message with complete logical by independent text object.
In order to solve above technical problem, the technical solution used in the present invention is: a kind of CAD electronic data Chinese version signal reconstruct method based on locus, specifically comprising the following steps that of the method
Step 1: will be stored in discrete text object to be reconstructed in CAD electronic data and read in internal memory, including the content of text of text object, text height and basic point coordinate；
Step 2: text object is read in internal memory successively according to physical storing sequence, then the Y coordinate according to text object basic point, discrete text object is ranked up branch, using the text height of text object as tolerance, when the difference of two text object basic point Y coordinate is in range of tolerable variance, using they text objects as same a line, then each style of writing object word is sorted according to the order that basic point Y coordinate is descending, so that it may discrete text object is divided into several rows；
Step 3: then according to the several rows text object obtained in step 2, selects same style of writing object word, according to the X-coordinate of text object basic point in same a line, is reordered by discrete for single file text object；For each row text object after branch in step 2, according to the order sequence that their basic point X-coordinate is ascending, obtain by left-to-right orderly text sequence.
Step 4: according to order in the row that step 2 and step 3 respectively obtain and line order row, obtain by left-to-right, the orderly text of multirow from top to bottom；Then the content of text of each row it is sequentially connected with and recombinates, obtaining the multiline text information with logical relation.
The present invention is based on the basic point coordinate of text object, by the basic point Y coordinate of discrete text object and basic point X-coordinate are performed twice at sequence, discrete text object is reconstructed into the text message with logical relation, method compared to existing technology, simple and convenient, easily operated, highly reliable.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, the present invention basic point coordinate according to independent text object, first analyze which text object and belong to same a line, again the text object of same a line is analyzed determining its sequencing, then the sequencing according to text object is recombinated, and obtains the restructuring text message with logical relation；
Specifically comprise the following steps that
Step 1: read in discrete text object to be reconstructed；Will be stored in the text object in CAD electronic data to read in internal memory, specifically include the content of text of text object, text height and basic point coordinate.
Wherein, text object Method of Data Organization in calculator memory is the memory data structure by realizing with computer programming language, the content of text of memory data structure organization and management text object, text height and basic point coordinate.Containing 4 text object TextA-TextD as shown in Figure 2, they are in fig. 2 according to broken box arrangement display.
Step 2: as it is shown on figure 3, the text object in TextA to TextD is read in internal memory successively according to physical storing sequence, the then Y coordinate according to text object basic point, discrete text object is ranked up branch.
Concrete grammar is: using the text height of text object as tolerance, when the difference of two text object basic point Y coordinate is in range of tolerable variance, using they text objects as same a line, then each style of writing object word is sorted according to the order that basic point Y coordinate is descending, so that it may discrete text object is divided into several rows.
The basic point Y coordinate of TextC and TextD is identical as shown in Figure 4, and relatively big, and therefore as the first row, and the basic point Y coordinate of TextA and TextB is identical, and the basic point Y coordinate less than TextC and TextD, therefore as the second row.
Step 3: the then X-coordinate according to the text object basic point in the same a line obtained in step 2, reorders discrete for single file text object；For each row text object after branch in step 2, it is ranked up according to their basic point X-coordinate.Method particularly includes: the basic point X-coordinate of text object is more little, the closer to left side, logically more forward according to writing style, is therefore sorted according to the order that basic point X-coordinate is ascending by the text object in each row, just obtains by left-to-right orderly text sequence.
The basic point X-coordinate of the first row TextC and TextD compares as shown in fig. 4-5, and TextD coordinate is less, and therefore TextD is front, and TextC is rear；In like manner, TextB is front, and TextA is rear.
Step 4: according to order in the row that step 2 and step 3 respectively obtain and line order row, discrete text object is attached and recombinates.Two minor sorts through step 2 and step 3, it is possible to obtain by left-to-right, the orderly text of multirow from top to bottom；Then the content of text of each row is sequentially connected with, discrete text object can be reassembled as the multiline text information with logical relation.
As it is shown in figure 5, the logical order after sequence is followed successively by TextD, TextC, TextB, TextA, successively the word content that each text object stores is coupled together, obtain the text message of reconstruct.
TextA-TextD shown in Fig. 2-Fig. 5 of the present invention is the text object representing broken box, splits storage at initial data textual object, is not a complete text fragment, is reconfigured to together by TextA-TextD by the method for the present invention.As can be seen here, discrete text object, based on the basic point coordinate of text object, can be reconstructed into the text message with logical relation by two minor sorts by the present invention.
Above-mentioned embodiment is not limitation of the present invention, and the present invention is also not limited to the example above, the change made within the scope of technical scheme of those skilled in the art, remodeling, interpolation or replacement, also belongs to protection scope of the present invention.
