Question

我正在尝试将我的PHP页面转换为PDF文件。但是我面临的问题是在转换成pdf之后，我无法查看我已经附加图像的顶部。而且pdf的质量越来越模糊。

我的形象是：

HTML / PHP

<div id="content2" style="background: #fff;border-bottom: 10px solid #ffffff;padding: 15px;border: 1px solid #000;width: 80%;margin: 0 auto;position: relative;overflow: hidden;margin-bottom: 15px;">

Answer 1

根据问题，您遇到了一个无法查看顶部的问题。

我已经解决了一些设计更改，最重要的是pdf.addHTML(selector, left, top, options, callback)有第二个和第三个参数表示左边和上边距，之前设置为-1,220，这是你没有得到的主要原因适当的设计pdf。

现在我也设置为pdf.addHTML($("#content2"), 0, 0, options, callback);。

PHP

<?php
$row['Payment_Date'] = date('Y-m-d');
$row['firstname'] = "Nikita";
$row['lastname'] = "Agarwal";
$row['pan'] = 'AKC230L';
?>

CSS

<style type="text/css">
    body{
        padding:0px;
        left:0px;
        top:0px;
        background-color:#ffffff;
    }
    tr{
        line-height:20px;
    }
    #content2{
        background: #fff;
        border-bottom: 10px solid #ffffff;
        padding: 15px;
        border: 1px solid #000;
        width: 80%;
        margin: auto 15px;
        position: relative;
        overflow: hidden;
        margin-bottom: 15px;
    }
    .width100{
        width:100%;
    }
    .padding20{
        padding:20px 0px;
    }
    .rowborder{
        border-bottom: 1px dotted;
        width: 100%;
        display: block;
    }
    .headerfont{
        font-size:25px;
    }
</style>
