Function: snapRectSpan()

function snapRectSpan(a, b, pixelRatio, phase?): [number, number];

Experimental

Snap a screen-space span [a, b] (either order) to the device-pixel grid. A non-empty span never collapses: it keeps at least one device pixel. Mirror of snapSpan in the vertex shader.

Parameters

Parameter	Type	Default value
a	number	undefined
b	number	undefined
pixelRatio	number	undefined
phase	number	0

Returns

[number, number]
