Transparent images are negatively reversed when converting documents to PDF from the NetDocuments Outlook toolbar.
- OS: Windows
- Office: N/A
- Product: ndOffice 2.0+
Issue
When you create a PDF from the Outlook NetDocuments toolbar (in an active New message/Reply/Forward with an attachment) using the 'Edit' button the output PDF may change the display of images with transparency to reverse colors like a negative image. e.g. black becomes white and white becomes black.
Cause:
The convert to PDF option uses the Microsoft Office conversion engine.
The default settings for the conversion opt for PDF/A1 format files to be output for compatibility reasons.
As part of the PDF/A1 specification transparent images are not allowed and so the transparency is not visible causing a 'negative' image.
Solution:
1) Open the document and save it to a PDF in Word first, the default options in Word do not select PDF/A options and it will correctly display.
We are considering exposing the same options available in Word to users via the Toolbar to address this in future versions.
