# We specify -s here to explicitly exclude SF_Opaque for single-color
# images.
# !! do we need /ImageMask parsing if we exclude SF_Mask here as well?
# Original sam2p order: Opaque:Transparent:Gray1:Indexed1:Mask:Gray2:Indexed2:Rgb1:Gray4:Indexed4:Rgb2:Gray8:Indexed8:Rgb4:Rgb8:Transparent2:Transparent4:Transparent8
# !! reintroduce Opaque by hand (combine /FlateEncode and /RLEEncode; or /FlateEncode twice (!) to reduce zeroes in empty_page.pdf from !)
