pure virtual

Set page range.

Convenience function to set the pages to be included in the output. Equivalent to calling setPageFilterLow() and setPageFilterHigh() with lower and upper page limits.

The default for each parameter is 0.

Parameters

pageLow	The lower page limit.
pageHigh	The upper page limit.

◆ setPanose()

virtual void JawsMako::IDistiller::setPanose ( const IInputStreamPtr & panose )

pure virtual

Sets a stream that refers to a list of CID font names and their associated Panose styles.

Each line of the list must consist of two fields that are tab delimited. The first field is the font name. The second field is the complete string representing the Panose Style entry. For example:

GothicBBBPr6-Medium<tab>0801020b0500000000000000 GothicBBB-Medium<tab>0801020b0500000000000000

If set, the default Panose style will be used when Jaws emits a CID font that is not in the list.

Equivalent to calling setParameter() with the parameter name "Panose" with appropriate values.

Parameters

panose The Panose stream.

◆ setParameter()

virtual void JawsMako::IDistiller::setParameter	(	const U8String &	param,
		const U8String &	value

pure virtual

Apply a key-value pair output parameter with a string value. The parameter name is case insensitive. Please refer to the supplied documentation for the details of the available parameters and their ranges.

Parameters

param	The parameter to change
value	The value to set

◆ setPdfVersion()

virtual void JawsMako::IDistiller::setPdfVersion ( ePDFVersion version )

version The PDF version to generate.

◆ setProlog()

virtual void JawsMako::IDistiller::setProlog ( const IInputStreamPtr & prolog )

pure virtual

Set a prolog stream to be consumed by the PostScript interpreter before the input stream is processed, or NULL to clear.

This stream will be both opened and closed, and will not be cloned; take care when opening multiple PostScript inputs with the same prolog simultaneously.

A prolog stream may also be set with setParameter() using either the "PrologFile" for a prolog file name value, or "PrologCommand" for prolog PostScript data.

Parameters

prolog The prolog stream to use.

◆ setResolution()

virtual void JawsMako::IDistiller::setResolution ( float resolution )

Parameters

resolution The desired resolution.

◆ setResourceDevicePath()

virtual void JawsMako::IDistiller::setResourceDevicePath ( const U8String & path )

pure virtual

Sets the resource device path.

Provides a method of using a custom PostScript resource device in place of the usual in-memory device used by IDistiller. A fully qualified directory path must be provided, and the directory must already exist, IDistiller will not create it automatically. The resource path must contain all the PostScript required for distilling, and additional fonts may be added when using addFont().

Parameters

path	The path name to use for the resource device.

◆ setSubsetFonts()

virtual void JawsMako::IDistiller::setSubsetFonts ( bool subset )

pure virtual

Parameters

subset Subset fonts?

◆ setThumbnails()

virtual void JawsMako::IDistiller::setThumbnails ( eThumbnailType thumbnails )

   name "thumbnails" with the enumeration value as a string
   ("None", "Color" or "Mono").  The default is eTHNone.

Parameters

thumbnails The desired thumbnail type.

◆ setTransfers()

virtual void JawsMako::IDistiller::setTransfers ( eTransferFunctionMethod transfers )

pure virtual

Set the desired method to for controlling transfer functions.

    Equivalent to calling setParameter with the parameter
    name "Transfers" with the enumeration value as a string
    ("Apply", "Remove" or "Preserve"). The default is eTRApply.

Parameters

transfers The desired transfer method.

◆ setTrimToBBox()

virtual void JawsMako::IDistiller::setTrimToBBox ( bool trimToBBox )

pure virtual
