I'm in doubt. I've tried what you've suggested, but I'm not sure if I'm
understand. I've tried one at time, but no increased quality founded.
The code I use is the following:
pdf=new DynaPDF
pdf.SetLicenseKey "..."
if not pdf.CreateNewPDF(f) then
Return
end if
'call pdf.SetJPEGQuality(100)
'call pdf.SetResolution(300)
call pdf.SetSaveNewImageFormat(false)
call pdf.SetCompressionFilter(pdf.kcfFlate)
g=new DynaPDFGraphics(pdf,20.0,20.0)
Then I read (from a db) the background image, I dray some text around the page.
I use the same instructions that I use in the printing (paper) functions.
pic=f.OpenAsJPEGMBS
(g as DynaPDFGraphics)
g.DrawPicture pic,0,0,ps.PageWidth,ps.PageHeight,0,0,pic.Width,pic.Height
Any ideas?

"C'è un equivoco di fondo. Si dice che il politico che ha avuto frequentazioni
mafiose, se non viene giudicato colpevole dalla magistratura, è un uomo onesto.
No! La magistratura può fare solo accertamenti di carattere giudiziale. Le
istituzioni hanno il dovere di estromettere gli uomini politici vicini alla
mafia, per essere oneste e apparire tali"
Paolo Borsellino
