Andriy updated PDFBOX-1510:
---------------------------
Attachment: doesnt_work.pdf
works2.pdf
> PDF gets corrupted when trying to extract it from the embedded files
> --------------------------------------------------------------------
>
> Key: PDFBOX-1510
> URL: https://issues.apache.org/jira/browse/PDFBOX-1510
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 1.7.1
> Reporter: Andriy
> Priority: Critical
> Attachments: doesnt_work.pdf, works2.pdf
>
>
> When a PDF is attached to another PDF it gets corrupted when retrieved
> through PDEmbeddedFile.getByteArray() method call. For some reason the
> returned array has less data than the original file that has been attached to
> the PDF.
> This affects some of the documents and not another. Below is the test code
> the replicates the issue.
> PDF that has an attachment that gets corrupted will be attached to the issue.
> public class PDFEmbeddedFiles {
> private PDFEmbeddedFiles() {
> }
> public static void main(String[] args) throws Exception {
> if (args.length != 1) {
> usage();
> System.exit(1);
> } else {
> PDDocument document = null;
> try {
> File pdfFile = new File(args[0]);
> /*
> String filePath = pdfFile.getParent()
> +
> System.getProperty("file.separator");
> */
> document = PDDocument.load(pdfFile);
> if (document.isEncrypted()) {
> try {
> document.decrypt("");
> } catch (InvalidPasswordException e) {
> System.err.println("Error: The
> document is encrypted.");
> } catch
> (org.apache.pdfbox.exceptions.CryptographyException e) {
> e.printStackTrace();
> }
