How to create and manipulate images with PHP

I studied the built-in function library of php and drew images. I originally came to this piece of knowledge with sadness and perseverance. After all, SVGdrawing is a big deal for me. After a brief look at the results, I found that it is still very simple. After all, many methods are built-in in PHP. You only need to understand the parameters and you can use them directly.

First of all, drawing a picture is divided into several steps:

Then proceed step by step according to the process of creating pictures. The source code is as follows

         $img = ImageCreate(400,60);   //创建一个宽400 高60的图片
    
         //创建以bg.jpg为背景的图片
         //$img = ImageCreateFromJpeg('./bg.jpg');

         //创建颜色
         $black = imagecolorallocate($img, 100, 116, 163); //创建颜色
         $red = imagecolorallocate($img,255,0,0);
         $white = imagecolorallocate($img,255,255,255);

         //绘制了矩形的轮廓
         imagerectangle($img, 10, 10, 30, 30, $white);

         //填充矩形
         imagefilledrectangle($img, 20, 20, 40, 40, $white);
     
         //填写文字
         imagettftext($img, 12, 0, 80, 35, $white, 'love.ttf', '大家好，这是我的网站!欢迎光临!');

         //生成图片
         header('Content-type:image/png');
         ImagePng($img);
         ImageDestroy($img);

Note: ImagePng($img,'my.png'); You can generate a picture of my.png under the current server path

The generated picture display effect is:

Of course, if a picture is the background ($img = ImageCreateFromJpeg('./bg.jpg') ) The display effect is:

This achieves the effect of direct manipulation of images through PHP~~ ~ Isn’t it very powerful? If you don’t have PS installed, you can just stretch out your little hand and type in a few lines of PHP code and it will be done. Haha~~~
