Description

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:

Could you fix this issue in a future version ?
