I am using spire.pdf.free 2.6.4 library. I am trying to convert the document to HTML format to show it in a viewer, in Windows it works fine but in Linux it shows me an exception. Below more details:
Application Server: Red Hat 7.5
Exception:
(default task-8) java.lang.NullPointerException

private String generateImageFromPDF(byte[] file) {
PdfDocument pdf = new PdfDocument();
pdf.loadFromBytes(file);
// convert the PDF to one SVG
pdf.getConvertOptions().setPdfToHtmlOptions(true);
// Save to SVG image
final ByteArrayOutputStream baos = new ByteArrayOutputStream();
pdf.saveToStream(baos, FileFormat.HTML);
return Base64.getEncoder().encodeToString(baos.toByteArray());
}
Thanks in advance.
