Step S103, the graphics primitive object data are carried out format conversion, translate into the data of character string forms, submit to syntax analyzer by data converter;
Step S104, by the semantic rules of syntax analyzer according to XML (extensible Markup Language) data definition unit, whether verification is legal legend data, if legal and just can be identified it is formed final vector quantization legend data, forward step S106 to, if the illegal step S105 that forwards to;
Step S105, for illegal legend data, output error message;
Step S106, by the legend manager according to Back ground Informations such as the classification of legend and titles, the vector quantization legend data after the translation are saved in the legend memory storage, realize the legend persistence, create vector quantization legend storehouse;
Step S107, process ends.
Five, vector quantization geologic legend application process implementing procedure
As shown in Figure 4, it is the implementing procedure figure of vector quantization geologic legend application process of the present invention, and it is the drawing process of vector quantization legend data to the vector quantization figure, comprising:
Step S201, use geologic data reading device read geologic data information;
Whether the geologic data information that step S202, basis read is used pick-up unit to detect geologic legend and is existed in vector quantization legend storehouse, forwards step S203 to if exist, and if there is no forwards step S208 to;
Step S203, use legend manager extract vector quantization legend data according to the type and the title of legend from the legend memory storage;
Step S204, analyze each key word in the legend data,, be split into single primitive data if discernible by syntax analyzer;
Step S205, pel is carried out format conversion, translate into the data layout that the graphic plotting function can use, transformation result is submitted to graphical interpreter by data converter;
Step S206, use graphical interpreter are created graphics primitive object according to primitive data, form vector quantization legend object;
The application mode of appointment and the regional environment of demonstration are carried out suitable convergent-divergent or distortion to each graphics primitive object in the legend entity in step S207, the geologic data information that reads according to step S201, use the graphic plotting device to draw out the vector quantization legend figure that meets user demand.
Step S208, geologic legend do not have vector quantization, forward vector nursing constructive process to;
Step S209, process ends.
Six, the vector quantization legend can be expanded the semantic implementing procedure of resolving
As shown in Figure 5, it can expand semantic process of analysis figure for vector quantization legend of the present invention, and it has been described with the expanded semantic analysis process of vector quantization legend data to vector quantization legend figure, comprising:
Be the vector quantization legend data of the character string forms of a reality below, immediately following one ": ", cut apart with ", " between the attribute after the key word of each fundamental figure pel, at last with "; " represent the end of this graph primitive definition.
Step S301, according to the type and the title of current legend of drawing, generate SQL statement and also in the legend memory storage, search the legend data;
Step S302, set up a vector quantization legend object entity according to the type and the title of legend, this legend object entity includes the set of depositing graphics primitive object, and the element figure object entity that parses later joined in the set of described graphics primitive object, use as a complete legend entity;
Step S303, use character string method for splitting split out pairing fundamental figure pel according to the key word in the syntactic definition;
Step S304, judge that the key word split out is whether wrong and maybe can be identified;
Maybe can not be identified if step S305 key word is wrong, with regard to output error message;
Step S306, judge whether key word is fundamental figure pel such as circle (circle), spline (SPL) etc.;
If step S307 key word is linewidthzoomflag (live width ratio change flag), basewidth (legend original width), baseheight (legend original height) and basecolor (legend background color), just its value is composed the corresponding primary attribute of giving the legend object;
Step S308 joins this graphics primitive object entity in the legend object at last if the fundamental figure pel carries out assignment just according to the corresponding graphics primitive object of key word establishment, and according to the graph primitive property value of definition to the graphics primitive object entity attribute;
Step S309, judge whether to also have the key word that does not split, if also have key word just to forward step S303 to; Otherwise just forward step S310 to;
Step S310, the occasion of using according to legend and the environment of current demonstration carry out convergent-divergent or subsection deformation according to the type of pel, thereby reach demands of applications;
Step S311, the data of pel are carried out suitable conversion, offer API and draw function and draw;
But step S312, obtain final vector quantization figure.
Use technique scheme, the present invention has following beneficial effect: the legend of the JPG static format by can not vector quantization resolves to the element figure form of XML (extensible Markup Language) grammer, and above-mentioned element figure can carry out the ratio variation or carry out deformation operation, this convergent-divergent and distortion application demand problem with regard to fundamentally having solved legend, realized the vector quantization of geologic legend, the easier geological map that obtains complete vector quantization, convenient and exactly tectonic structure is analyzed when the researchist is used; The legend data of character string forms are kept in the legend memory storage, solved the persistence problem of vector quantization legend, realized once creating reusing, can further set up perfect vector quantization legend storehouse, also can be other application scenario reliable legend Data Source is provided; Undistorted convergent-divergent and change of shape that the legend that realizes by this method can be accomplished arbitrary proportion; When forming shape library, adopt industry standard to carry out legend and build the storehouse, can realize that the standard of legend is unified; Because legend has adopted extendible element figure form, has realized the extensibility of legend, also can well express for some complicated especially legends.Can improve the precision of geological research for the oil geology researchist provides geological map accurately and reliably.
As above-mentioned, clear legend vectorization method and the device that has described the geological map of the present invention's proposition in detail, and the technique effect of application technical solution of the present invention.But this area those skilled in the art are appreciated that under the situation of the spirit and scope of the present invention that do not deviate from the claims definition, can make multiple modification in form and details.
