----------------------------------------------------------------
not a case of forgetfulness ... rendering to bitmap image the ExportState
should be considered and not the ViewState as recommended in [Adobes
PDF32000_2008.pdf|https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf]
chapter 8.11.4.4:
{quote} Export dictionary (Optional). A dictionary containing one entry,
ExportState, a name whose
value shall be either ON or OFF. This value shall indicate the
recommended state for content in this group when the document (or part of
it) is saved by a conforming reader to a format that does not support
optional content (for example, a raster image format).

But this also should have nearly no impact because PDF's with differing View-
and ExportState are very, very rare. Wonder if they exists.
