-----------------------------------
Resolution: Duplicate
> Visual signature in bad proportions
> -----------------------------------

> Key: PDFBOX-2282
> URL: https://issues.apache.org/jira/browse/PDFBOX-2282
> Project: PDFBox
> Issue Type: Bug
> Components: Rendering, Signing
> Affects Versions: 1.8.6, 1.8.7, 2.0.0
> Reporter: Cyril Bremaud
> Priority: Minor

> I want to convert into a picture a signed PDF document with a visual
> signature. This visual signature is done with functions of PDFBox. The
> resulting image has a visual signature, but in bad proportions (it is much
> smaller).
> I use addSignature() method to add a visual signature that works very well.
> The problem may be at the addSignature () function or at PDFToImage()
> function.
> Note that the document signed with PDFBox visualizes very well with Adobe
> Reader and the signature created with Adobe Reader converts correctly in
> picture.
> Also some PDF documents are very badly converted into image, I think
> especially at this Adobe document that is totally unreadable when converted:
> http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/acrobat_digital_signature_appearances_v9.pdf
> Could you fix this issue in a future version ?
