Detailed Description

VolumeTexture class represents a 3D dimentional image.

Constructor & Destructor Documentation

VolumeTexture() [1/3]

VolumeTexture::VolumeTexture

(

)

Constructs a null texture.

See also

VolumeTexture::isNull()

VolumeTexture() [2/3]

VolumeTexture::VolumeTexture	(	int	width,
		int	height,
		int	depth = 1,
		QImage::Format	format = QImage::Format_ARGB32
	)

Constructs a texture with the given width, height, depth and format.

A null texture will be created if parameters are not valid.

VolumeTexture() [3/3]

VolumeTexture::VolumeTexture ( const QVector< QImage > &  slices )

explicit

Constructs a texture from the given slices array of images.

All images in the aray must have the same size and format, otherwise null texture is constructed. The width, height and format of the texture will be equal to the width and heigth of the images in the array. The depth of the texture will be equal to the size of the array.

Member Function Documentation

convertToFormat()

VolumeTexture VolumeTexture::convertToFormat	(	QImage::Format	format,
		Qt::ImageConversionFlags	flags = Qt::AutoColor
	)		const

Returns a copy of the texture in the given format.

The specified image conversion flags control how the texture data is handled during the conversion process.

isNull()

bool VolumeTexture::isNull

(

)

const

Returns true if it is a null texture, otherwise returns false.

A null texture has all parameters set to zero and no allocated data.

pixel()

QRgb VolumeTexture::pixel	(	int	x,
		int	y,
		int	z
	)

Returns the color of the pixel at coordinates (x, y, z).

See also

VolumeTexture::setPixel();

setSlice()

void VolumeTexture::setSlice	(	int	index,
		const QImage &	image
	)

Fills the data at the given index z coordinate from the image.

Image must have same format, width and heigth as this texture.
