Embodiment 1

[0076] Please refer to figure 1 , image 3 and Figure 4 , Embodiment 1 of the present invention is:

[0077] A method for displaying vector graphics based on an embedded man-machine interface, comprising:

[0078] S1. Load a preset PVG graphic, extract the text information of the PVG graphic, and cache each status graphic contained in the PVG graphic, and the preset PVG graphic includes multiple states of preset components graphics;

[0079] Wherein, the loading of the preset PVG graphics is specifically:

[0080] A PVG graphic corresponding to the preset component is added to the display position of the preset component, and each state graphic in the PVG graphic is loaded respectively.

[0081] In this embodiment, the engineer created a PVG graphic (part vector graphic, component vector graphic) on the PC in advance, which is also a vectorized graphic described by specific text, which contains the number of states of the picture, and each state Use the status tag to di...

Embodiment 2

[0090] Please refer to figure 2 , the second embodiment of the present invention is:

[0091] A vector graphics display terminal 1 based on an embedded human-machine interface, including a processor 2, a memory 3, and a computer program stored on the memory 3 and operable on the processor 2, and the processor 2 executes the computer program At this time, the steps in the first embodiment above are realized.

[0092]To sum up, the present invention provides a vector graphics display method and terminal based on an embedded man-machine interface. The present invention loads PVG vector graphics with a plurality of status graphic information stored therein, and caches the status graphics therein, so that the status When switching, it is not necessary to modify the graphic description text like SVG graphics and reload, and directly select the corresponding status graphics for display, saving a lot of system resources; and the present invention does not need to install SVG dynamic...

Abstract

The invention discloses a vector diagram display method based on an embedded human-computer interface. The method comprises the steps: loading a preset PVG graph, extracting the text information of the PVG graph, and caching all state graphs contained in the PVG graph, wherein the preset PVG graph comprises a plurality of state graphs of preset parts; according to the running state of the current equipment and the display condition information of the state graph, selecting the corresponding state graph and the text information to be drawn and displayed; receiving an operation request of a user, executing the operation request, correspondingly changing the equipment state, and according to the changed equipment state and the display condition information of the state graph, selecting the state graph and the text information corresponding to the current state of the equipment from the cache to be drawn and displayed. According to the invention, a large number of system resources are saved; and the SVG dynamic library does not need to be installed, so that the storage space of the equipment is greatly saved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a vector display method and terminal based on an embedded man-machine interface. Background technique [0002] SVG (Scalable Vector Graphics) is a new two-dimensional vector graphics format formulated by W3C (World Wide Web ConSortium, the Internet Standards Organization) in August 2000, and it is also a network vector graphics standard in the specification. SVG is a new generation of network image format that is completely based on XML (Extensible Markup Language) and can be integrated with the above-mentioned technologies. SVG is not just an image format. Because it is an XML-based language, it means that it inherits the cross-platform and extensibility of XML, thus taking a big step in the reusability of graphics. For example, SVG can be embedded in other XML documents, and other XML content can also be embedded in SVG documents, and various SVG graphics can be easily combi...
