DiscardAlternateImages

When this option is ON, any Alternate Images defined for a given image (Images in different resolutions than the base image) will be discarded. Default is ON.

SubsetAllEmbeddedFonts

When this option is ON, any fonts which are embedded, but not subset, will be replaced with subset fonts. This can save considerable space in a document, but does so at the risk of preventing future edits to the document. Default is ON.

ReSubsetAllSubsetFonts

When this option is ON, any fonts which are subset embedded, will be replaced with a newly subset font. This will generally only happen if the document has been edited since it was created, or the document contains only a subset of the page that it originally contained. NOTE: This can only REMOVE glyphs from the subset font. It cannot add glyphs that were not present int he original subset. Default is ON.

RemoveAllEmbeddedFonts

When this option is ON, all embedded fonts will be removed. If this is done, the document can only be viewed on platforms which contain all of the fonts required. Generally, you would want to do this only in very tightly controlled circumstances. Default is OFF.

RemoveAllBase14Fonts

This will remove any embedded base 14 fonts. Generally, it is safe to remove these fonts, as any platform that supports PDF should have locally available copies of them. However, there is still some risk that the embedded fonts are not identical to the actual base14 fonts, and hence may render differently. Default is OFF.

MergeDuplicateFonts

When this option is ON, the document will be searched for mutliple copies of the same font. These will then be combined into a single font. Default is ON.
