Hi,
you would need to include an OutputIntents entry into the DocumentCatalog. I
think at that point in time there is no high level API for that.
A sample entry would look like this (Generated by Acrobat X)
(COSName{OutputIntents}:COSArray{[COSDictionary{(COSName{DestOutputProfile}:COSDictionary{(COSName{Filter}:COSName{FlateDecode})
(COSName{Length}:COSInt{2574}) (COSName{N}:COSInt{3})
(COSName{Range}:COSArray{[COSFloat{0.0}, COSFloat{1.0}, COSFloat{0.0},
COSFloat{1.0}, COSFloat{0.0}, COSFloat{1.0}]}) }) (COSName{Info}:COSString{sRGB
IEC61966-2.1}) (COSName{OutputCondition}:COSString{})
(COSName{OutputConditionIdentifier}:COSString{Custom})
(COSName{RegistryName}:COSString{http://www.color.org})
(COSName{S}:COSName{GTS_PDFA1}) (COSName{Type}:COSName{OutputIntent}) }]}).
Kind regards
