Go language graphics programming technology analysis and practical guide

As a fast and efficient programming language, Go language has always been loved by programmers. It can be used not only for backend development but also for graphics programming. This article will discuss how to perform graphics programming in the Go language from two aspects: technical analysis and practical guidance. Specific code examples will be given in the second half of the article.

Technical Analysis

For graphics programming in Go language, we usually use third-party libraries to implement it. One of the most commonly used libraries is github.com/ajstarks/svgo, which provides a convenient and concise way to generate SVG graphics. SVG is a vector graphics format described using XML that supports many graphic effects and interactive features.

When using the svgo library, we first need to import the library:

import "github.com/ajstarks/svgo"

Then, we can create an SVG canvas and draw various graphics on it, such as Lines, rectangles, circles, etc. By setting different properties, we can adjust the color, size, position, etc. of the graphics. Finally, we output the generated SVG graphic to a file or display it directly in the browser.

Practice Guide

Next, we will use a simple example to demonstrate how to use the svgo library for graphics programming in the Go language. We will create a simple SVG graphic containing a rectangle and a circle.

First, we need to create an SVG canvas and set the size of the canvas:

svg := svg.New(os.Stdout)
svg.Start(500, 500)

Then, we can draw a rectangle and a circle on the canvas:

svg.Rect(100, 100, 200, 200, "fill='red'")
svg.Circle(300, 300, 50, "fill='blue'")

Finally, we need to end the SVG canvas and output the generated SVG graphic to a file:

svg.End()

Run the above code, we can see an SVG graphic containing rectangles and circles in the output.

Through the above introduction, we can see that it is not difficult to perform graphics programming in the Go language. With the help of appropriate libraries and some simple codes, various complex graphics effects can be achieved. I hope the content of this article will be helpful to you, and I hope you can have more exploration and practice in the field of graphics programming in Go language.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
