IE11 doesn't support the `slice` method on ArrayBufferViews, so
we have to use the old `Array.prototype.slice.call` trick in the
tests instead.
for (let x = 0;x < 16;x++) {
let pixel;
if ((x < 4) && (y < 4)) {
for (let x = 0;x < 16;x++) {
let pixel;
if ((x < 4) && (y < 4)) {
- pixel = checked_data.slice((y*4+x)*4, (y*4+x+1)*4);
+ // NB: of course IE11 doesn't support #slice on ArrayBufferViews...
+ pixel = Array.prototype.slice.call(checked_data, (y*4+x)*4, (y*4+x+1)*4);
} else {
pixel = [0, 0xff, 0, 255];
}
} else {
pixel = [0, 0xff, 0, 255];
}
