Question

我的html中有5个base64嵌入式图像。 4个PNG和1个JPG。将html转换为PDF时，该过程失败。从html删除JPG图片节点时，它可以正常工作！

iTextPDF7的Java代码：

HtmlConverter.convertToPdf(new File(src), new File(dest));

JPG base64 HTML img：

<img content-height="4.22cm" content-width="7.45cm" src="data:image/jpg;base64,/9j/4AAQSkZJRgABAQEBLAEsAAD/4Q4kRXhpZgAATU..........

PNG base64 HTML img：

<img content-width="scale-down-to-fit" width="100%" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAG4AAACrCAY........

我收到此错误消息：

错误的Base64输入字符为76:37（十进制）18：34：13.582 [main] 错误c.i.h.r.resource.ResourceResolver-无法检索图像具有给定的基本URI（文件：/ D：/ PDFCONVERTER / ITEXPDF7 / html /）和图像源路径（数据：image / jpg; base64，/ 9j / 4AAQSkZJRgABAQEBLAEsAAD / 4Q4kRXhpZgAATU0AKgAAAAgAB .................）

使用以下方法打开html文件

1）Chrome，看起来还可以！！所有图片都可以。 2）Internet Explorer 8，相同的JPG图像，和另一个（PNG），未显示在页面上。 3）Internet Explorer 11，所有图像都可以。

这让我更加困惑。

Answer 1

我发现了问题。 JPG base64已损坏。它们仅在HTML base64 JPG图像中包含许多“％”字符。将XML + XSLT转换为HTML时，JPG base 64损坏。原始XML JPG base 64中没有“％”字符。现在，我必须看看我的trasnform操作。谢谢。
