Detailed Description

The ManagedColor class is a class to handle colors that are color managed.

A managed color is a color of which we know the model(RGB, LAB, CMYK, etc), the bitdepth and the specific properties of its colorspace, such as the whitepoint, chromaticities, trc, etc, as represented by the color profile.

Krita has two color management systems. LCMS and OCIO. LCMS is the one handling the ICC profile stuff, and the major one handling that ManagedColor deals with. OCIO support is only in the display of the colors. ManagedColor has some support for it in colorForCanvas()

All colors in Krita are color managed. QColors are understood as RGB-type colors in the sRGB space.

We recommend you make a color like this:

colorYellow = ManagedColor("RGBA", "U8", "")
QVector<float> yellowComponents = colorYellow.components()
yellowComponents[0] = 1.0
yellowComponents[1] = 1.0
yellowComponents[2] = 0
yellowComponents[3] = 1.0
 
colorYellow.setComponents(yellowComponents)
QColor yellow = colorYellow.colorForCanvas(canvas)

Constructor & Destructor Documentation

◆ ManagedColor() [1/3]

ManagedColor::ManagedColor ( QObject * parent = 0 )

explicit

ManagedColor Create a ManagedColor that is black and transparent.

Definition at line 26 of file ManagedColor.cpp.

◆ ManagedColor() [2/3]

ManagedColor::ManagedColor	(	const QString &	colorModel,
		const QString &	colorDepth,
		const QString &	colorProfile,
		QObject *	parent = 0 )

ManagedColor create a managed color with the given color space properties.

See also: setColorModel() for more details.

Definition at line 33 of file ManagedColor.cpp.

◆ ManagedColor() [3/3]

ManagedColor::ManagedColor	(	KoColor	color,
		QObject *	parent = 0 )

Definition at line 44 of file ManagedColor.cpp.

◆ ~ManagedColor()

ManagedColor::~ManagedColor ( )

override

Definition at line 51 of file ManagedColor.cpp.

Member Function Documentation

◆ colorDepth()

QString ManagedColor::colorDepth ( ) const

colorDepth A string describing the color depth of the image:

U8: unsigned 8 bits integer, the most common type
U16: unsigned 16 bits integer
F16: half, 16 bits floating point. Only available if Krita was built with OpenEXR
F32: 32 bits floating point

Returns: the color depth.

Definition at line 92 of file ManagedColor.cpp.

◆ colorForCanvas()

QColor ManagedColor::colorForCanvas ( Canvas * canvas ) const

colorForCanvas

Parameters

canvas the canvas whose color management you'd like to use. In Krita, different views have separate canvasses, and these can have different OCIO configurations active.

Returns: the QColor as it would be displaying on the canvas. This result can be used to draw widgets with the correct configuration applied.

Definition at line 60 of file ManagedColor.cpp.

◆ colorModel()

QString ManagedColor::colorModel ( ) const

colorModel retrieve the current color model of this document:

A: Alpha mask
RGBA: RGB with alpha channel (The actual order of channels is most often BGR!)
XYZA: XYZ with alpha channel
LABA: LAB with alpha channel
CMYKA: CMYK with alpha channel
GRAYA: Gray with alpha channel
YCbCrA: YCbCr with alpha channel

Returns: the internal color model string.

Definition at line 97 of file ManagedColor.cpp.

◆ colorProfile()

QString ManagedColor::colorProfile ( ) const

Returns: the name of the current color profile

Definition at line 102 of file ManagedColor.cpp.

◆ components()

QVector< float > ManagedColor::components ( ) const

components

Returns: a QVector containing the channel/components of this color normalized. This includes the alphachannel.

Definition at line 123 of file ManagedColor.cpp.

◆ componentsOrdered()

QVector< float > ManagedColor::componentsOrdered ( ) const

componentsOrdered()

Returns: same as Components, except the values are ordered to the display.

Definition at line 130 of file ManagedColor.cpp.

◆ fromQColor()

ManagedColor * ManagedColor::fromQColor	(	const QColor &	qcolor,
		Canvas *	canvas = 0 )

static

fromQColor is the (approximate) reverse of colorForCanvas()

Parameters

qcolor	the QColor to convert to a KoColor.
canvas	the canvas whose color management you'd like to use.

Returns: the approximated ManagedColor, to use for canvas resources.

Definition at line 76 of file ManagedColor.cpp.

◆ fromXML()

void ManagedColor::fromXML ( const QString & xml )

Unserialize a color following Create's swatch color specification available at https://web.archive.org/web/20110826002520/http://create.freedesktop.org/wiki/Swatches_-_color_file_format/Draft.

Parameters

xml	an XML color

Returns: the unserialized color, or an empty color object if the function failed to unserialize the color

Definition at line 157 of file ManagedColor.cpp.

◆ operator==()

bool ManagedColor::operator== ( const ManagedColor & other ) const

Definition at line 55 of file ManagedColor.cpp.

◆ setColorProfile()

bool ManagedColor::setColorProfile ( const QString & colorProfile )

setColorProfile set the color profile of the image to the given profile.

The profile has to be registered with krita and be compatible with the current color model and depth; the image data is not converted.

Parameters

colorProfile

Returns: false if the colorProfile name does not correspond to to a registered profile or if assigning the profile failed.

Definition at line 107 of file ManagedColor.cpp.

◆ setColorSpace()

bool ManagedColor::setColorSpace	(	const QString &	colorModel,
		const QString &	colorDepth,
		const QString &	colorProfile )

setColorSpace convert the nodes and the image to the given colorspace.

The conversion is done with Perceptual as intent, High Quality and No LCMS Optimizations as flags and no blackpoint compensation.

Parameters

colorModel	A string describing the color model of the image: A: Alpha mask RGBA: RGB with alpha channel (The actual order of channels is most often BGR!) XYZA: XYZ with alpha channel LABA: LAB with alpha channel CMYKA: CMYK with alpha channel GRAYA: Gray with alpha channel YCbCrA: YCbCr with alpha channel
colorDepth	A string describing the color depth of the image: U8: unsigned 8 bits integer, the most common type U16: unsigned 16 bits integer F16: half, 16 bits floating point. Only available if Krita was built with OpenEXR F32: 32 bits floating point
colorProfile	a valid color profile for this color model and color depth combination.

Returns: false the combination of these arguments does not correspond to a colorspace.

Definition at line 115 of file ManagedColor.cpp.

◆ setComponents()

void ManagedColor::setComponents ( const QVector< float > & values )

setComponents Set the channel/components with normalized values.

For integer colorspace, this obviously means the limit is between 0.0-1.0, but for floating point colorspaces, 2.4 or 103.5 are still meaningful (if bright) values.

Parameters

values the QVector containing the new channel/component values. These should be normalized.

Definition at line 142 of file ManagedColor.cpp.

◆ toQString()

QString ManagedColor::toQString ( )

toQString create a user-visible string of the channel names and the channel values

Returns: a string that can be used to display the values of this color to the user.

Definition at line 171 of file ManagedColor.cpp.

◆ toXML()

QString ManagedColor::toXML ( ) const

Serialize this color following Create's swatch color specification available at https://web.archive.org/web/20110826002520/http://create.freedesktop.org/wiki/Swatches_-_color_file_format/Draft.

Definition at line 147 of file ManagedColor.cpp.
