The Nine-slice component is a way to preserve the edges of an image while scaling it to the desired size.

var uComps = require('u-components');
var uActions = require('u-actions');
var Action = uActions.Action;
new Action('Nine Slice Demo', nineSliceDemo)
.addParameter('Nine Slice', uActions.ParamType.NINE_SLICE)
.register();
function nineSliceDemo(comp) {
var nineSliceComp = uComps.cast.toNineSlice(comp);
nineSliceComp.filename = 'umajin_logo.png';
nineSliceComp.sliceTop = 30;
nineSliceComp.sliceBottom = 30;
nineSliceComp.sliceLeft = 30;
nineSliceComp.sliceRight = 30;
nineSliceComp.borderScale = 75;
nineSliceComp.borderPadding = 20;
nineSliceComp.tint = '#559ca0';
}
