Java无法删除图像文件，写入PDF后将itext7 html转换为Pdf转换图像文件

Question

I am creating a multi page PDF file from HTML templates. There are some images as well that I'm showing in PDF. PDF generate successfully and images are added in PDF file. But After this when I want to delete images they are not deleting, Popup appears that files are locked. When I kill the program that writes PDF file, then you can delete images.

public void createPdf(String htmlString) throws IOException {
     PdfWriter writer = new PdfWriter("C:\\Users\\DELL\\Desktop\\filename.pdf");
     PdfDocument pdf = new PdfDocument(writer);

     ConverterProperties properties = new ConverterProperties();
     HtmlConverter.convertToPdf(htmlString, pdf, properties);

     pdf.close();
     writer.close();
}

Note

1. I am converting HTML text to pdf.
2. In html text img tag is used to insert external images from local file system.

Answer 1

This indeed is a bug in iText7. It has been fixed already and the fix will be available in 7.1.2 release (and correspondingly pdfHTML 2.0.2).

If you want to use the fixed version already, you can build iText Core from sources yourself. The commit fixing the issue is 4565db5de87666dc60d65befb463a0519fb8334d . You don't have to build custom pdfHTML version because fix was only in iText7 Core.

Build instructions are available here .
