Constructor & Destructor Documentation

◆ Layer()

inviwo::Layer::Layer	(	const Layer &	rhs,
		NoData	noData,
		const LayerConfig &	config = {} )

Create a layer based on rhs without copying any representations. State from rhs can be overridden by the config

Parameters

rhs	source layer providing the necessary information like dimensions, swizzle masks, interpolation, spatial transformations, etc.
noData	Tag type to indicate that representations should not be copied from rhs
config	custom parameters overriding values from `rhs`

Member Function Documentation

◆ clone()

virtual Layer * inviwo::Layer::clone ( ) const

overridevirtual

Implements inviwo::Data< Layer, LayerRepresentation >.

◆ getAsCodedBuffer()

std::unique_ptr< std::vector< unsigned char > > inviwo::Layer::getAsCodedBuffer ( const std::string & fileExtension ) const

encode the layer contents to a buffer considering the requested image format

Parameters

fileExtension file extension of the requested image format

Returns: encoded layer contents as std::vector

◆ getAxis()

virtual const Axis * inviwo::Layer::getAxis ( size_t index ) const

overridevirtual

returns the axis information corresponding to index

Exceptions

RangeException if index is out of bounds, i.e. index >= 2

Implements inviwo::SpatialEntity.

◆ getDimensions()

virtual size2_t inviwo::Layer::getDimensions ( ) const

overridevirtual

Implements inviwo::StructuredGridEntity< 2 >.

◆ getWorldSpaceGradientSpacing()

vec3 inviwo::Layer::getWorldSpaceGradientSpacing ( ) const

Computes the spacing to be used for gradient computation. Also works for layers with non-orthogonal basis.

For orthogonal lattices this will be equal to the world space texel spacing. For non-orthogonal lattices it will be the longer of the axes projected onto the world space axes.

   World space

    b ^           ^
     /            |

y ^ / dy | / texel | | /__________>a \/ | <-—dx---> |____________> x

The actual gradient spacing vectors are given by mat3{ gradientSpacing.x, 0, 0, 0, gradientSpacing.y, 0, 0, 0, gradientSpacing.y } However, we do not return the zeroes.

To get the spacing in texture space use: mat3{glm::scale(worldToTextureMatrix, getWorldSpaceGradientSpacing())};

Returns: Step size for gradient computation in world space.

◆ setDataFormat()

void inviwo::Layer::setDataFormat ( const DataFormatBase * format )

Set the format of the data.

See also: DataFormatBase

Parameters

format The format of the data.

◆ setDimensions()

virtual void inviwo::Layer::setDimensions ( const size2_t & dim )

virtual

Resize to dimension. This is destructive, the data will not be preserved. Use copyRepresentationsTo to update the data.

Note: Resizes the last valid representation and erases all other representations. Last valid representation will remain valid after changing the dimension.

◆ setSwizzleMask()

void inviwo::Layer::setSwizzleMask ( const SwizzleMask & mask )

update the swizzle mask of the channels for sampling color layers The swizzle mask is only affecting Color layers.

Parameters

mask	new swizzle mask
