CN103247021A - Method for converting SVG into LPF vector graphics - Google Patents

Abstract

The invention discloses a method for converting an SVG (scalable vector graphics) into LPF (low pass filter) vector graphics. The method comprises the following steps: at first, elements of an SVG graphic object are respectively converted into elements in corresponding LPF vector graphics, filters used in the elements are analyzed, linear gradient and the radiation gradient in the SVG are analyzed, and transition of multiple colors is carried out in the same pel; then, in the converted LPF vector graphics, the dynamic picture display of the LPF vector graphics is realized through compiling Javascripts, and data and data alarm in a highsoon real-time database are displayed to a user through pel flashing and color changing manners; and the LPF vector graphics are transferred in an Oracle of an application server through a configuration tool, the user uses a portal system and opens the configuration graphics through a configuration ActiveX, and the LPF vector graphics are obtained from the application server and are displayed to the user. Under the condition that the LPF vector graphics are amplified or changed in size, the graphics quality cannot be influenced.

Description

A kind of SVG polar plot is converted to the method for LPF polar plot

Technical field

The present invention relates to a kind of two bit vector bitmap-format conversion methods based on the XML language, belong to electric system portal website view shows field.

Background technology

SVG scalable vector graphics (Scalable Vector Graphics) is based on extend markup language (XML), is used for describing a kind of graphical format of two-dimension vector graphics.SVG is that W3C is a kind of new two-dimension vector graphics form that the Internet normal structure was formulated in August, 2000, also is the network vector graphics standard in the standard.The XML grammer is deferred in the SVG strictness, and describes picture material with the descriptive language of text formatting, is a kind of therefore and the irrelevant vector graphics format of image resolution ratio.

The SVG graphical format has the following advantages: 1, vector shows object, is not subjected to resolution limit; 2, based on XML; 3, adopt text to come description object; 4, have interactivity and dynamic; 5, support DOM fully.　

But the SVG polar plot can not satisfy some actual demand of electric system at present fully, trend analysis is checked as measuring point, day/moon/year curve is checked, the convenient of senior pels such as pie chart, excellent figure, histogram, panel board, LED drawn, Real-time Alarm in the picture, and function such as real time data and historical data in the Dynamic Display Hisoon database.

Therefore, need provide a kind of and transfer SVG form polar plot to have LPF form polar plot by oneself instrument, transfer SVG form polar plot to LPF, use the Hisoon configuration instrument to open then, and be published in the Hisoon gate system, realize that the user is for the advanced requirement of electric system configuration figure.

Summary of the invention

Above-mentioned defective at existing based on two bit vector bitmap-format conversion methods of XML language in the prior art the invention provides the method that a kind of SVG polar plot is converted to the LPF polar plot.By drawing instrument and the ActiveX space that the Hisoon configuration instrument provides, the C S that can realize the LPF form shows and the polar plot that embeds Web is showed, the LPF image amplify or varying sized situation under its graphical quality can not lose.The LPF image provides abundant element figure, finished product pel, dynamic pel, supports functions such as real time data monitoring, historical inverting, trend analysis, Javascript script.

Technical scheme of the present invention is:

A kind of SVG polar plot is converted to the method for LPF polar plot, and concrete steps are as follows:

(1) outside provides SVG Drawing Object;

(2) object elements of the SVG Drawing Object that step (1) is provided is converted to the element among the corresponding LPF respectively, and the filter that uses in the parsing element, add special effect to shape and text, resolve linear gradient and radiation gradual change among the SVG, realize a kind of color to the seamlessly transitting of other colors, and the transition of a plurality of colors is used in the same pel;

(3) in the good LPF of conversion, by writing the mode of Javascript script, realize that the dynamic menu of LPF is showed, by flicker, the colour switching mode of pel, show data and data alarm in the Hisoon real-time data base to the user;

(4) by configuration instrument, LPF is imported among the Oracle of application server, the user uses gate system, opens configuration figure by the configuration ActiveX control, obtains described LPF from application server, and shows the user.

Further, the object elements of the described SVG Drawing Object of step (2) comprises line (line), circle (circle), oval (ellipse), rectangle (rectangle), polygon (polyline), path (path) element.

The invention has the beneficial effects as follows:

LPF by transferring SVG configuration figure to LPF configuration figure, in the face of browsing the user who checks real time data in the Hisoon real-time data base by configuration instrument, has realized following function on the basis of SVG:

1, shows real-time tendency analysis and historical trend analytic curve;

2, show a day tracing analysis, month tracing analysis, year tracing analysis and analysis of statistical data;

3, configuration figure and HighSoon real-time data base is mutual, and the interface after a series of encapsulation is provided;

4, the configuration figure that draws and trend analysis module are published to the Hisoon gate system with the form of ActiveX control;

5, the real time execution situation by web access configuration figure and carry out trend analysis;

6, provide historical inverting function;

7, support figure layer technology;

8, support that ActiveX is published to the Hisoon gate system.

Description of drawings

Fig. 1 is that SVG is to LPF transfer process synoptic diagram;

Fig. 2 is that LPF uses the displaying procedure chart by configuration instrument.

Embodiment

Below in conjunction with accompanying drawing the present invention is explained in further detail.

The method that a kind of SVG polar plot of the present invention is converted to the LPF polar plot is:

Figure changes by object with SVG form configuration, with SVG Drawing Object wherein: elements such as line, circle, ellipse, rectangle, polyline, polygon, path, be converted to the element among the corresponding LPF respectively, and the filter that uses in the parsing element, add special effect to shape and text, resolve linear gradient and radiation gradual change among the SVG, realize a kind of color to the seamlessly transitting of other colors, and the transition of a plurality of colors is used in the same pel.

In the good LPF of conversion, by writing the mode of Javascript script, realize that the dynamic menu of LPF is showed then, flicker by pel, modes such as colour switching are better showed data and data alarm in the Hisoon real-time data base to the user, as shown in Figure 1.

By configuration instrument, LPF is imported among the Oracle of application server then.The user uses gate system, when opening configuration figure by the configuration ActiveX control, obtains this LPF from application server, and shows the user, as shown in Figure 2.

It is as follows to realize that by the Hisoon configuration instrument SVG configuration figure is converted to LPF configuration graphic operation process:

1, open the Hisoon configuration instrument, click begins-opens-the SVG file;

2, the SVG file that selection will be changed in the dialog box that ejects;

3, open this SVG file;

4, carrying out necessary Javascript script writes;

5, click begins-saves as, and configuration figure is saved as the LPF file.
