createRandomColor()

static ImageUInt8Ptr mmcfilters::ImageUtils::createRandomColor ( int *  img, int  numRowsOfImage, int  numColumnsOfImage  )

inlinestatic

Creates a random-colour visualisation from an integer-labelled image.

The output is a row-major uint8_t image with three adjacent columns per input pixel, storing RGB triples as (R, G, B). Labels are used as array indices and therefore must be non-negative.

Parameters

img	Pointer to numRowsOfImage * numColumnsOfImage integer labels.
numRowsOfImage	Number of input rows.
numColumnsOfImage	Number of input columns.

Returns

RGB visualisation encoded as an image with numColumnsOfImage * 3 columns.

Definition at line 331 of file Image.hpp.

to1D()

static PixelId mmcfilters::ImageUtils::to1D ( int  row, int  column, int  numColumns  )

inlinestaticnoexcept

Converts (row, column) to a row-major linear index.

Parameters

row	Zero-based row coordinate.
column	Zero-based column coordinate.
numColumns	Number of columns in the image domain.

Returns

Linear index row * numColumns + column.

Definition at line 303 of file Image.hpp.

to2D()

static std::pair< int, int > mmcfilters::ImageUtils::to2D ( PixelId  index, int  numColumns  )

inlinestaticnoexcept

Converts a row-major linear index to (row, column).

Parameters

index	Row-major linear index.
numColumns	Number of columns in the image domain.

Returns

Pair (row, column).
