Detailed Description

This class describes a post-processing step whereby one or more spot colorants folded into the process components post-render.

The main use case for this feature is overprint simulation for spot colorants. With spot merging, the spot components will be rendered in addition to the process components, natively processing all overprints and colors as if the output device supports all these components. Then the spots may be folded into the process components by this post process step.

Another use is to allow exact output color values to be specified for spot components for the best possible spot color matching on the ultimate output device.

It also provides a method of previewing on screen the result of printing to a real device which supports those colorants. For example, a method of doing this would be to:

• Create a renderspec with processSpace set to the device color space.
• Add a CColorConversionPostProcessSpec to convert to the display color space, usually an RGB space.
• Add a CSpotMergePostProcessSpec to merge spot colorants into the final result, where the colorants are specified in that RGB space.

The spot components may also be pre-processed using tone curves before the merging takes place; use the toneCurves member of this class to implement this.

The spot colorants specified here must not be specified in the retainSpots list; the colorants here are considered additional to any specified therein.

There must be no more than one CSpotMergePostProcessSpec in a post-processing chain.

Member Function Documentation

create()

static JAWSMAKO_API CSpotMergePostProcessSpecPtr JawsMako::CSpotMergePostProcessSpec::create ( const IDOMColorSpaceDeviceN::CColorantInfoVect & _mergeSpotColors, const CEDLVector< CFloatVect > & _toneCurves = CEDLVector< CFloatVect >() )

static

Create a tone-mapping post process.

Parameters

_mergeSpotColors	The list of spot colorants, specified in the current color space at the current position in the post processing chain, that are to be merged into the process components.
_toneCurves	The (optional) tone curves to be applied to the spot colorants before merging into the process components. If provided, there must be a tone curve for every merged colorant. Please see CToneCurvesPostProcessSpec for a description of the tone curve format.

Returns

CSpotMergePostProcessSpecPtr The tone-mapping post process

getType()

virtual ePostProcessType JawsMako::CSpotMergePostProcessSpec::getType ( ) const

inlinevirtual

Get the type of post processing this spec represents.

Returns

ePostProcessType The post process type. See ePostProcessType
