Problem: The Emoji expression is stored in 4 bytes, so the traditional MySQL utf-8 encoding can only be stored for a maximum of 3 bytes.FIX: Modify MySQL (5.5.3 or above) encoded as UTF8MB4 to store the emoji table, and set the set names UTF8MB4 otherwise the program writes and reads garbled. Requirements: MySQL 5.5.3 or more (online said), I did not test, I use MySQL 5.6 pro-test, can be stored.To modify t

What is SVG? SVG refers to a scalable vector graphic (Scalable vector graphics) SVG is used to define vector-based graphics for the network SVG defines graphics using XML format SVG images have no loss of graphics quality when zoomed in or changed size

I. What is SVG? SVG is a 2D graphic description language released by W3C in 1999. It is a markup language based solely on XML format. The full name is extensible vector graphics, which is very different from traditional raster graphics (JPG, PNG, GIF, etc.). No. SVG is a 2D graphics development platform. It consists of two parts: XML-based data description and Th

Preface-Why Learn Snap.svg.jsBefore the webapp of the technology group, some people feel that the form of svg+animate feel very flashy, vector graphics arbitrarily enlarged and do not need to download pictures, and the effect of the mobile phone end smooth.(The biggest difference between a vector graph and a bitmap is that it is not affected by resolution.) You can zoom in or out of a graphic without affecting the clarity of the diagram.It can be disp

Join us today to learn about a lightweight class library that implements the SVG path stroke drawing and animation, we introduce the segment from easy to use, detailed usage, resources and cases, and source code interpretation.1. Easy to get started Add segment to the HTML aspect to define path. JS uses path to instantiate a segment, then you can use the segment draw method. var MyPath = document.getElementById ("My-path"), segment = new segme

SVG (Scalable Vector Graphics) SVG is an open vector graphics Description Language Based on XML. SVG images are compatible with xml1.0. SVG elements are instructions for drawing images. The viewer interprets these instructions to display SVG images on specified devices.

In the previous article, we talked about the font rendering mechanism and the causes of Iconfont aliasing, and how to draw high-quality SVG ICON, and provide a set of AI templates for your reference.The following will tell the front-end side how we use SVG to make high-definition iocn, and good support for the individual browser under the PC, and compatible with more than ie6+ browser.From the previous arti

Recently began to look at Vue, first use the official template to quickly build up the project: Vue.js provides an official command-line tool that can be used to quickly build large single-page applications. The tool provides an out-of-the-box build tool configuration that brings a modern front-end development process. Create and launch a project with hot reload, static check on save, and build configuration that can be used in a production environment in just a few minutes. Now the project Webp

Baidu Encyclopedia:svg Scalable Vector graphics (Scalable vector graphic) is a graphic format for describing two-dimensional vector graphics based on Extensible Markup Language (XML). SVG is a new two-dimensional vector graphics format developed by the Web, and also the standard of network vector graphics in specification. SVG strictly conforms to the XML syntax and describes the image content in a descript

Article Introduction: Svg/vml+js implements a cross browser vector graphics implementation scheme. Raphael JS Library is in the Webrebuild conference to listen to experts will arrive, and then looked at the next, really strong--through the SVG/VML+JS implementation of the cross-browser vector graphics implementation program.

In recent months to do more development, storage nickname is essential, but this evil support emoji expression do nickname, it is a bit of egg painThe General MySQL table is designed with the UTF8 character set. The nickname field with emoji is gone insert , and the entire field becomes an empty string. What's going on here?It turns out that MySQL's UTF8 character set is 3 bytes, and

Reason:The UTF-8 encoding can be two, three, and four bytes. The emoji expression is 4 bytes, while MySQL UTF8 encodes up to 3 bytes, so data cannot be plugged in.Workaround:Convert MySQL encoding from UTF8 to UTF8MB4Steps:1.
