Hi,
I read that most programs convert PNG images to JPEG images while creating PDF
files.
Is this also true for ConTeXt/LuaTeX? What happens when PNG images are
included?
Regards
Marco

The only time this will (or should) happen w/ any program is when creating a .pdf w/ a specification which sets pixel images to use compression JPEG compression.
I don't believe there are any pdf-creating tex implementations which will reprocess images in this fashion (normally they're simply encapsulated in the file as is).
