void	setColorLabel (int index)
	setColorLabel sets a color label index associated to the layer. The actual color of the label and the number of available colors is defined by Krita GUI configuration.

bool	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.

bool	setColorSpace (const QString &colorModel, const QString &colorDepth, const QString &colorProfile)
	setColorSpace convert the node to the given colorspace

void	setInheritAlpha (bool value)

	shearNode perform a shear operation on this node.

QImage	thumbnail (int w, int h)
	thumbnail create a thumbnail of the given dimensions. The thumbnail is sized according to the layer dimensions, not the image dimensions. If the requested size is too big a null QImage is created. If the current node cannot generate a thumbnail, a transparent QImage of the requested size is generated.

virtual QString	type () const
	type Krita has several types of nodes, split in layers and masks. Group layers can contain other layers, any layer can contain masks.

Detailed Description

The CloneLayer class A clone layer is a layer that takes a reference inside the image and shows the exact same pixeldata.

If the original is updated, the clone layer will update too.
