What Is a Graphics Editor?

Graphics and image software, software tools for drawing and editing various graphics, including: vector graphics, engineering drawings, flowcharts, structural drawings, etc. It is widely used in almost all fields related to work, life, production, education, technology, and publishing.

It is mainly divided into online and offline. Offline, such as Photoshop, Illustrator, Flash, Matlab, Coreldraw, etc .; online can be divided into plug-in and non-plug-in, plug-in way.

As far as formula editing is concerned, graphic editing is more widely used in almost all fields involving work, life, production, education, science and technology, and publishing. There are also countless types of graphic editing software installed on local computers, but web graphics The editing problem has not been systematically resolved for a long time.

At present, the main method for solving graphic editing and publishing in web pages is to first edit the graphics using local software (such as Photoshop, Flash, Mathlab, etc.), then output or convert the images into the specified format, and finally upload them to the specified web file. . In terms of web-based online editing and communication, this solution has the following disadvantages:

1. The network client must independently install the corresponding graphic editing software, and the use of such graphic editing software is more professional, and it is not easy to master without certain training;

2. The commonly used design and drawing functions (such as the design and drawing functions of software such as Photoshop) are not compatible with the calculation and drawing functions (such as the calculation and drawing function of software such as Matlab) commonly used in education and science and technology, causing users not only to install A variety of graphic editing software, and because the drawing software uses different methods and habits, it causes inconvenience to users;

3. The graphics edited in commonly used graphics editing software need to be output and converted into a picture of the specified format, and then upload the picture to the specified web file. The operation process is more complicated, and the uploaded picture can only be viewed on the Internet. Does not support online editing and modification, can not meet people's use based on network communication, not to mention support for graphics-based search and identification;

4. After uploading pictures of different formats to the webpage, the display quality of the pictures is related to the size of their file size. Generally, the higher the requirements for the picture display quality, the larger the corresponding picture file size, and the print quality of the webpage pictures are both not tall;

5. The speed of opening a webpage file containing pictures is mainly restricted by the speed of opening pictures in them. The pictures in various webpages not only occupy a large amount of network server storage resources, but also increase the transmission pressure of network bandwidth, which greatly improves the network server's Operating costs.

From a technical point of view, although the function of editing some simple graphics based on web pages can already be achieved, from the perspective of solving the online editing and modification of vector graphics in a non-plug-in manner, and solving the compatibility of common design drawing and calculation drawing functions, based on the network The problem of editing and modifying graphics online has actually become a web-based technical bottleneck that restricts people in the fields of education, learning, research, and work. ^[1]

Graphic editor basic introduction

The webpage graphic editor (hereinafter referred to as GraphPlay) is a software system based on Web for online editing, publishing, browsing, copying, and modifying graphics. This system is developed using JavaScript, runs on various Windows platform terminals, and is widely applicable to mainstream browsers such as IE. GraphPlay breaks through the technical bottlenecks that currently severely restrict people's network-based information release, education and learning, scientific research, technical exchanges, and literature library construction. Its advanced, practical, and economic features provide people with open and convenient Internet-based communication. With efficient editing tools.

Graphic editor software features

(1) Based on Web usage, network terminals do not need to install any plug-ins;

Web graphics editing system

(2) Represent graphics in VML , with beautiful display and clear printing;

(3) Visually edit vector graphics, friendly user interface, and support online copying, pasting and modifying of graphics;

(4) Support for generating curves based on formulas, fitting and adjusting curves based on key points, and formula identification of various graphics;

(5) Based on the VML description graphic information, the storage pressure of the network server is minimized;

(6) Graphic editing and analysis are completed at the network terminal, and the pressure of network transmission is minimized.

Graphic editor main editing functions

GraphPlay has rich vectorized graphic editing functions, and supports formula identification of various types of graphs and the function of generating function curves based on expressions.

In addition, the top of GraphPlay is also designed with "File", Edit, View, Drawing and other menus. Among them, the "Drawing" menu includes automatic generation of points, lines, regular polygons, circles by entering data or expressions. , Ellipse, elementary function curve and other functions. ^[1]
