Abstract

The invention discloses a vector site map drawing method based on a mobile terminal, which relates to the technical field of drawings. The method comprises the following steps: S1, detecting a contact point when a finger presses down, and determining a beginning position of a drawing graphic primitive by the pressed contact point; S2, detecting contact points when the finger moves until the finger lifts up, and determining the termination position of the drawing graphic primitive by the contact point when the finger lifts up; and S3, drawing the graphic primitive in a rectangular zone defined by the beginning position and the termination position on a canvas. According to the invention, the method for drawing on a portable terminal is realized. The method is suitable for inspection personnel to quickly draw a site map.

Description

technical field [0001] The invention relates to the technical field of drawing, in particular to a mobile terminal-based vector scene drawing method. Background technique [0002] At present, there are very few softwares capable of drawing vector graphics in the Android system, and only two softwares, AndCAD and AutoCADWS, have the function of drawing vector graphics. AndCAD is a drawing tool with relatively simple functions. It allows users to create simple geometric shapes. Its main features include camera rendering, DXF file import / export, alignment drawing mode, graphics rotation, copying and moving, etc. AutoCADWS is a very powerful drawing tool designed to allow users to view, edit and share DWG drawings through web browsers or mobile devices. Users can work with anyone, anywhere, and store AutoCAD drawings and project files in an easily accessible online workspace. They can also view and edit designs online or on Apple iPad, iPhone, iPod touch, and Android devices. ...
