Detailed Description

This class describes a tiff grayscale.

This class opens, closes, and query information from a single tiff image. Data can be queried using matrix like indices with the bracket operator or using space coordinates using the parenthesis operator.

Constructor & Destructor Documentation

TIFFGrayscale()

Dune::Copasi::TIFFGrayscale::TIFFGrayscale ( const std::filesystem::path & filename, std::size_t max_cache = 8 )

explicit

Constructs a new instance.

Parameters

[in]	filename	The filename
[in]	max_cache	The maximum row cache.

Member Function Documentation

cols()

std::size_t Dune::Copasi::TIFFGrayscale::cols

(

)

const

The size of cols for this file.

Returns

Number of cols in this file

operator()()

double Dune::Copasi::TIFFGrayscale::operator() ( double pos_x, double pos_y )

noexcept

TIFF value by position call operator.

Here we assume that TIFFTAG_RESOLUTIONUNIT has same units as the grid. Since we never check grid units, we also do not check tiff units

Parameters

[in]	pos_x	The x position in same units as the tiff file
[in]	pos_y	The y position in same units as the tiff file

Returns

Scaled TIFF value if x and y are in the TIFF domain, 0 otherwise

operator[]()

const TIFFGrayscaleRow & Dune::Copasi::TIFFGrayscale::operator[]

(

std::size_t

row

)

const

Array indexer row operator.

Warning

Row object is only a proxy object and ... TODO

Parameters

[in]

row

The row index

Returns

The row

rows()

std::size_t Dune::Copasi::TIFFGrayscale::rows

(

)

const

The size of rows for this file.

Returns

Number of rows in this file

size()

std::size_t Dune::Copasi::TIFFGrayscale::size

(

)

const

The size of rows for this file.

Returns

Number of rows in this file
