◆ blockStyleClass()

template<class RowPrefix , class ColPrefix >
std::string Dune::DefaultSVGMatrixOptions::blockStyleClass ( const RowPrefix &  row_prefix,
const ColPrefix &  col_prefix 
) const
inline

Helper function that returns an style class for a given prefix.

Note
This function is only a helper to the default writeSVGBlock and is not required for custom options classes.

◆ writeBlockTitle()

template<class Stream , class RowPrefix , class ColPrefix , class Block >
void Dune::DefaultSVGMatrixOptions::writeBlockTitle ( Stream &  out,
const RowPrefix &  row_prefix,
const ColPrefix &  col_prefix,
const Block &  block 
) const
inline

Helper function writes a title for a given block and prefix.

Note
This function is only a helper to the default writeSVGBlock and is not required for custom options classes.

◆ writeSVGBlock()

template<class Stream , class RowPrefix , class ColPrefix , class Block >
void Dune::DefaultSVGMatrixOptions::writeSVGBlock ( Stream &  out,
const RowPrefix &  row_prefix,
const ColPrefix &  col_prefix,
const Block  block,
const std::array< std::size_t, 4 > &  svg_box 
) const
inline

Write an SVG object for a given block/value in the matrix.

This function is called for every matrix block; that includes root and intermediate nested blocks of matrices. SVG blocks are written from outer to inner matrix blocks, this means that in case of overlaps in the SVG objects, the more nested blocks take precedence.

Warning
If the SVG bounding box is not respected, the content may be omitted in the final SVG view.
Note
This function signature is required for any custom options class.
Template Parameters
StreamAn ostream type (possibly a NullStream!)
RowPrefixA ReservedVector
ColPrefixA ReservedVector
BlockThe type of the current block
Parameters
outAn stream to send SVG object to
row_prefixA multindex of indices to access current row
col_prefixA multindex of indices to access current column
blockThe current matrix/sub-block/value
svg_boxSVG object bounding box (position and sizes).

◆ color_fill

std::function<std::string(const double&)> Dune::DefaultSVGMatrixOptions::color_fill

Color fill for default options.

Example:

opts.color_fill = [max,min](const double& val){
auto percentage = (val-min)/(max-min)*100;
return "hsl(348, " + std::to_string(percentage) + "%, 41%)";};
};
constexpr auto max
Function object that returns the greater of the given values.
Definition: hybridutilities.hh:484
constexpr auto min
Function object that returns the smaller of the given values.
Definition: hybridutilities.hh:506
