Set the intercept color space for DeviceGray. This is the color space that will be used for conversion if the color manager is asked to convert from or to DeviceGray.

Parameters

space The desired DeviceGray intercept color space.

◆ setDeviceRGBIntercept()

virtual void IColorManager::setDeviceRGBIntercept ( const IDOMColorSpacePtr & space )

pure virtual

Set the intercept color space for DeviceRGB. This is the color space that will be used for conversion if the color manager is asked to convert from or to DeviceRGB.

Parameters

space The desired DeviceRGB intercept colorspace.

◆ setMapDeviceGrayToCMYKBlack()

virtual void IColorManager::setMapDeviceGrayToCMYKBlack ( bool mapGrayDirectly )

pure virtual

Configure how DeviceGray colors are converted to DeviceCMYK.

Normally, all color conversions in JawsMako are achieved using color management. In particular, this includes the DeviceGray, DeviceCMYK and DeviceRGB color spaces, which are converted using the intercept color spaces configured in the functions below.

However this means that conversions between DeviceGray and DeviceCMYK generally pass through ICC conversion. Gray values may not map exclusively to DeviceCMYK K values, resulting in non-zero values in the Cyan, Magenta and Yellow components.

This may be unsuitable in some environments, in particular when dealing with overprint simulation.

This behavior can be changed with this member. If the argument is

true: All color conversions from DeviceGray to DeviceCMYK will simply map and invert the gray value to the K channel. This will also apply to any rendering operations performed by JawsMako.
false (default): The intercept color spaces will be used to convert from DeviceGray to DeviceCMYK.

Parameters

mapGrayDirectly Determine how DeviceGray colors are converted to DeviceCMYK

◆ testGamut()

virtual bool IColorManager::testGamut	(	uint32	numColors,
		const IDOMColorSpacePtr &	sourceSpace,
		const IDOMColorSpacePtr &	destSpace,
		eRenderingIntent	intent,
		eBlackPointCompensation	bpc,
		const float *	inColors )

pure virtual

Tests whether the result of gamut checking is within the gamut of the destination color space.

Currently, only base color spaces are supported; Indexed and DeviceN spaces cannot be used.

Device Link profiles are not supported.

Parameters

numColors	The number of colors to test.
sourceSpace	The color space describing the input samples.
destSpace	The desired destination color space.
intent	The desired rendering intent for the test.
bpc	The desired handling of black point compensation. If in doubt, use eBPCDefault.
inColors	Pointer to the input sample buffer.

Returns: bool false, if any colors are Out-Of-Gamut, true otherwise.

◆ useDeviceLinkForConversionsBetween() [1/2]

virtual void IColorManager::useDeviceLinkForConversionsBetween	(	const IDOMColorSpaceICCBasedPtr &	sourceSpace,
		const IDOMColorSpaceICCBasedPtr &	destSpace,
		const IDOMICCProfilePtr &	deviceLink )

pure virtual

Set the DeviceLink ICC profile with specifying a combination of the source color space and the destination color space. If the same combination of sourceSpace and destSpace was specified with different DeviceLink ICC profile, the old DeviceLink ICC profile is replaced with the new DeviceLink ICC profile.

Parameters

sourceSpace	The desired input color space.
destSpace	The desired output color space.
deviceLink	The desired DeviceLink ICC profile.

◆ useDeviceLinkForConversionsBetween() [2/2]

virtual void IColorManager::useDeviceLinkForConversionsBetween	(	const IDOMICCProfilePtr &	sourceProfile,
		const IDOMICCProfilePtr &	destProfile,
		const IDOMICCProfilePtr &	deviceLink )

pure virtual

Convenience version of useDeviceLinkForConversionsBetween() that accepts IDOMICCProfiles instead of IDOMColorSpaceICCBased.

Parameters

sourceProfile	The desired input color profile.
destProfile	The desired output color profile.
deviceLink	The desired DeviceLink ICC profile.
