HTML to PDF conversion, Base64 image tag is not displaying image in PDF
Question
Trying to convert html content to pdf in java using dependencies core renderer.jar, itext-2.0.8.jar and itextpdf-5.5.13.1.jar.I'm not getting image content but other contents of HTML can able to view in PDF.
The html file contains an image tag with base64 encoded
< img style = "width = 10px; height = 10px;" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAARMAAAC3CAMAAAAGjUrGAAAAk1BMV...g==" />
creating pdf using java function which accepts the html content in string buffer as input and creates the PDF file.
public void createReport(StringBuffer sb) {
try {
String tempfile = outputPath + File.separator + "outputPdf.pdf";
PrintWriter writer = new PrintWriter(inputPath, StandardCharsets.UTF_8);
writer.println(sb.toString());
writer.close();
String url = new File(inputPath).toURI().toURL().toString();
OutputStream os = new FileOutputStream(new File(tempfile));
ITextRenderer renderer = new ITextRenderer();
ITextFontResolver resolver = renderer.getFontResolver();
resolver.addFont("C:\\Users\\DELL\\AppData\\Local\\Microsoft\\Windows\\Fonts\\ANGSA.ttf",BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
renderer.setDocument(url);
renderer.layout();
renderer.createPDF(os);
os.close();
} catch (Exception e) {
e.printStackTrace();
}
}

This works for me with flying-saucer 9.1.20 and iText 2.1.7. You should update your dependencies and/or check your base64 string.
The jar was added through maven:
<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>flying-saucer-pdf</artifactId>
<version>9.1.20</version>
</dependency>
