Na página Visão geral do Ghostscript , encontrei o Ps2pdf.htm explica dPDFSETTINGS
:
-dPDFSETTINGS=
configuration
Presets the "distiller parameters" to one of four predefined settings:
/screen
selects low-resolution output similar to the Acrobat Distiller "Screen Optimized" setting./ebook
selects medium-resolution output similar to the Acrobat Distiller "eBook" setting./printer
selects output similar to the Acrobat Distiller "Print Optimized" setting./prepress
selects output similar to Acrobat Distiller "Prepress Optimized" setting./default
selects output intended to be useful across a wide variety of uses, possibly at the expense of a larger output file.
Na mesma página, MaxSubsetPct
aparece apenas em uma tabela de "parâmetros reconhecidos do Acrobat Distiller 5 definidos no documento DistillerParameters incluído no SDK do Acrobat" e vincula-se a esse SDK.
Em vez de baixar o SDK grande, procurei por "Parameters do Distiller" no site da Adobe e encontrei Adobe PDF Creation Settings que explica o MaxSubsetPct na página 88:
MaxSubsetPct
Supported by: all applications
Type: integer
UI name: Subset embedded fonts when percent of characters used is less than: value %
Default value: 100The maximum percentage of glyphs in a font that can be used before the entire font is embedded instead of a subset. The allowable range is 1 through 100.
Distiller only uses this value if SubsetFonts is
true
. For example, a value of 30 means that a font will be embedded in full (not subset) if more than 30% of glyphs are used; a value of 100 means all fonts will be subset no matter how many glyphs are used (because you cannot use more than 100% of glyphs).
