I have already fixed that problem , in the apache pdfbox core (which causes
structural changes) and now everything works great.Thank you, my friend :) It
was caused by structural changes - indirect/direct references was changed.
Tilman Hausherr

Martin Schröder

> Rounding issue in generated PDF file
> ------------------------------------
>
> Key: PDFBOX-1778
> URL: https://issues.apache.org/jira/browse/PDFBOX-1778
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel, Signing
> Affects Versions: 1.8.3
> Reporter: vakhtang koroghlishvili
> Priority: Critical
> Attachments: original.pdf, saved.pdf
>
>
> We have PDF file which was signed by some other application.
> When we try to sign it with PDFbox, previous revision is damaged.
> We did some investigations and found such problem:
> (question on stackoverflow is here:
> http://stackoverflow.com/questions/19903884/pdf-document-is-modified-by-another-revision/19905271?noredirect=1#19905271
> )
> Some PDF tags are changed in new revisions.
> For example values of following tags:
> /WhitePoint
> /Gamma
> /Matrix
> are changed from values like this: 0.9505
> to values like this: 0.9505000114
> We think this is problem of converting float/double inside COSFloat.
> Following code just opens and saves PDF file and this operation changes
> values of mentioned text:
> public void saveTo(String sourceFile, String destFile) throws Exception{
> PDDocument doc = PDDocument.load(new FileInputStream(sourceFile));
> doc.save(new FileOutputStream(destFile));
> }
