Detailed Description

Immutable projection of ordered contour edges onto support pixels.

One pixel is yielded for each edge. A pixel can therefore occur more than once when different edges occupy different sides of that pixel.

Member Function Documentation

◆ begin()

iterator mmcfilters::ContourPixelRange::begin ( ) const

inline

Returns an iterator to the first edge pixel.

Returns: First pixel position.

Definition at line 221 of file ContourTrace.hpp.

◆ empty()

bool mmcfilters::ContourPixelRange::empty ( ) const

inlinenoexcept

Returns whether the range contains no pixels.

Returns: True when the range is empty.

◆ end()

iterator mmcfilters::ContourPixelRange::end ( ) const

inline

Returns the exclusive end iterator.

Returns: Position following the final pixel.

Definition at line 224 of file ContourTrace.hpp.

◆ size()

std::size_t mmcfilters::ContourPixelRange::size ( ) const

inlinenoexcept

Returns the number of projected edge pixels, including repetitions.

Returns: Projected pixel count.
