Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The terms "first," "second," "third," and "fourth" and the like in the description and in the claims and drawings are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, result, or characteristic described in connection with the embodiment may be included in at least one embodiment of the invention. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a terminal, as shown in fig. 1, the terminal may include: the terminal comprises a processor, a memory and a display screen, wherein the memory and the display screen are connected with the processor through a bus, and the terminal specifically comprises: computers, servers, smartphones, tablets, and the like.

Scalable vector graphics (Scalable Vector Graphics, simply "svg") is a graphics format based on the extensible markup language (XML) for describing two-dimensional vector graphics. SVG is formulated by W3C and is an open standard. SVG strictly follows XML syntax and describes image content in a descriptive language in text format and is therefore a vector graphics format independent of image resolution.

In the power grid industry, as dwg drawings cannot be browsed online without plug-ins, the conventional method is to convert dwg drawings into svg drawings and browse the drawings through a browser.

In the design process of CAD, two types of TEXT are included, respectively TEXT and MTEXT (multi-line TEXT) description modes.

For different types of text, such as "M16 bolt", referring to fig. 2, fig. 2 is a representation of two different "M16 bolts", in svg drawing, especially in a representation of multiple lines of text, it is possible to represent "M16 bolts" as "M16" and "bolts", and in actual operation, no matter which is presented, it is desirable to automatically identify "M16 bolts" as a set of words when clicking on a word in the whole "M16 bolt", and perform a hot spot operation on it, such as displaying information of attribute, parameter, etc. of "M16 bolts", instead of displaying attribute, parameter of "M16" when clicking on "M16", and displaying attribute, parameter of "bolts" when clicking on "bolts". To achieve overall clicking, it is then necessary to determine "M16" and "bolt" as a group.

Referring to fig. 3, fig. 3 provides a text grouping method in a svg drawing of a power grid, the method is applied in a terminal shown in fig. 1, and as shown in fig. 3, the method includes the following steps:

step S301, a terminal acquires a first file in a svg format derived by CAD, and reads the first file by adopting a DOM programming interface;

step S302, traversing all the TEXT (TEXT) nodes in the first file to obtain transformation matrix information and font size of each TEXT node;

the information for two TEXT nodes for one svg is shown below:

wherein, the information in matrix is transformation matrix information (1.383317892 e-016-2.2591295592.823911949 1.729147365e-016 137.3676277 128.4540804), such as matrix (1.383317892 e-016-2.259129559 2.823911949 1.729147365e-016 137.3676277 128.4540804); for font sizes, for example, font-size= "1.397829316" and font-size= "1.397829316".

Step S303, dividing the TEXT nodes with the same font size into a group to obtain alpha groups of TEXT nodes, wherein each group of the TEXT nodes comprises at least two TEXT nodes;

the font size of the two TEXT nodes is font-size= "1.397829316", and the TEXT nodes are determined to be the same group.

Step S304, setting up the transformation matrix corresponding to any two TEXT nodes in the alpha group of TEXT nodes to obtain an operation result, and determining whether the any two TEXT nodes are the same TEXT TEXT according to the operation result;

step S305, if it is determined that the two TEXT nodes belong to the same TEXT, merging the two TEXT nodes into a merged TEXT, and sorting the merged TEXT from left to right according to TEXT coordinates from top to bottom to obtain a sorted merged TEXT.

According to the technical scheme, the same word size is determined to be the same group, then the transformation matrixes corresponding to any two TEXT nodes in the same group are subjected to setting operation to obtain an operation result, whether the any two TEXT nodes are the same node or not is determined according to the operation result, if the any two TEXT nodes are the same node, the two TEXT nodes are combined into one TEXT node, so that the results of the two TEXT nodes cannot appear when clicking, and the user experience degree is improved.

Optionally, the method may further include:

and comparing the TEXT information in the ordered TEXT with a preset TEXT template to determine the maximum TEXT length of the match, and adding a hot spot tag (< a > tag) to the maximum TEXT length to form a hot spot.

According to the technical scheme, the identification of the hot spot is carried out on the characters capable of forming the hot spot, so that the search of the hot spot is convenient, the hot spot is similar to a hot search word, and the hot spot can be different in different fields.

The setting operation includes: one or any combination of displacement, rotation, scaling or beveling operations. Specific implementation of the above setting operation can be found in the paper understanding SVG transform coordinate transformation.

The determining whether the two TEXT nodes are the same TEXT according to the operation result specifically may include:

if the operation result is non-rotation, non-scaling and the offset of the horizontal and vertical coordinates of the displacement operation result is within the set number of font sizes, determining that any two TEXT nodes are the same TEXT.

For the same TEXT, first, the TEXT information of the same nature uses the same font of the same font size for the same file, for example, the font used by an 'M16 bolt' is the same, if the TEXT information is displayed in two rows, the corresponding transformation is proved to be free from rotation or scaling, if the rotation or scaling occurs, the TEXT data of two rows are determined not to be the same TEXT, in addition, the displacement distance of the TEXT information of the same TEXT is not too large, as shown in fig. 2, namely, the deviation of the displacement is in an integral font size, so that the judgment on whether the TEXT information is the same TEXT can be realized in this way.

Referring to fig. 4, fig. 4 provides a text grouping method in a svg drawing, and the method is shown in fig. 4, and includes the following steps:

step S1, an SVG drawing is opened, nodes in the SVG file are analyzed in a dom mode, all the nodes of text are found, and the nodes are stored in an array.

Step S2.2 traversing the extracted TEXT information, calculating the distance between the two information by the transformation matrix thereof, and judging the possibility of the same TEXT

Step S2.3 reassembles the data, possibly as a group.

string FinalListStr＝string.Join("",LinkedTest.ToArray())；

ServerTagList.Where(x＝>new Regex(x)

.IsMatch(FinalListStr)).OrderBy(x＝>x.Length).ToList()；

By comparing the data in the server with the data in the current system, if the data can be matched correctly, the data is indicated to be the longest array which can be identified.

And S3, adding hot spots.

Hotspots are added to the characters in the svg, so that editing interaction can be performed, as follows:

the application also provides a terminal, the terminal includes:
