extensions/alignment/core/alignment_axis library

Enums

AlignmentHorizontal

Horizontal placement on the -1, 1 alignment axis.

AlignmentVertical

Vertical placement on the -1, 1 alignment axis.

Constants

kAlignmentEpsilon → const double

Default tolerance for comparing alignment coordinates to zero.

Functions

alignmentIsNearZero(double value, {double epsilon = kAlignmentEpsilon}) → bool

Returns true when value is effectively zero for alignment math.

horizontalAxisOf(double x, {double epsilon = kAlignmentEpsilon}) → AlignmentHorizontal

Resolves x to a horizontal axis bucket.

horizontalAxisOfDirectional(double start, {double epsilon = kAlignmentEpsilon}) → AlignmentHorizontal

Resolves directional start to a horizontal axis bucket.

verticalAxisOf(double y, {double epsilon = kAlignmentEpsilon}) → AlignmentVertical

Resolves y to a vertical axis bucket.
