Question

pCharts文档说您应该能够使用此代码将图像渲染到浏览器。

mypic.php

$myPicture->stroke;

的mypage.html

<IMG SRC=‘mypic.php‘>

img标签应该调用php脚本。在PHP脚本中，笔触函数设置content-type: image/png。

所以这就是我所拥有的：

netsales.php

<?php
     include('../class/pData.class.php');
     include('../class/pDraw.class.php');
     include('../class/pImage.class.php');

     /* query sales and create new image */

     $myPicture->stroke;
?>

的index.php

<?php
     include ('netsales.php');
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
     <div>
          <img src="netsales.php" />
     </div>
</body>
</html>

我没有收到任何错误，只有红色X表示丢失的图像。

Answer 1

尝试删除

<?php
     include ('netsales.php');
?>

从index.php开始，添加

header('Content-Type: image/png');

在中风之前。

Answer 2

我尝试这样的事情并且有效：

//html file//////////////////////
<?php include ('my.php'); ?>

<html>
<head></head>
<body>

<div> <img src="my.php" /> </div>

</body>

</html>
///////////////////////////////////


//my.php file/////////////////////////
<?php

 /* pChart library inclusions */ 
 include("pChart/class/pData.class.php"); 
 include("pChart/class/pDraw.class.php"); 
 include("pChart/class/pImage.class.php"); 


 //...


 $myPicture->autoOutput("picture.png"); 

?>
///////////////////////////////////

Answer 3

我让它为我工作我在HTML文件中有注释包含功能：

<?php //include ('my.php'); ?>

pChart不会呈现到Web浏览器，只显示缺少的图像
