Function: computeNineSliceRegions()
computeNineSliceRegions(
width,height,pivot,uvOffset,uvScale,slices):NineSliceRegion[]
Defined in: rendering/utilities/compute-nine-slice-regions.ts:226
Computes the nine-slice regions for a sprite, given its current size, and
cuts each stretching band into tiled segments where its mode is 'tile'.
Corner regions are always a single, fixed-size quad. Edge regions stretch
or tile along their one free axis (edgeMode); the center region
stretches or tiles along both axes (centerMode). A border with an inset
of 0 (the default for any axis with no slicing) collapses to just its
center band, so a sprite with no insets at all degenerates to the single
region a non-sliced sprite would render.
Parameters
width
number
The sprite's current width, in unscaled sprite-space units.
height
number
The sprite's current height, in unscaled sprite-space units.
pivot
The sprite's pivot, normalized to its own size and Y-up
((0, 0) is bottom-left, (1, 1) is top-right), matching
SpriteEcsComponent.pivot.
uvOffset
The sprite's texture rect offset, 0 to 1.
uvScale
The sprite's texture rect size, 0 to 1.
slices
The nine-slice configuration.
Returns
Up to nine regions, each a quad to draw in place of the sprite's single quad.
