postDraw(callback): void;

Set this layer's post-draw callback.

Parameters

Parameter	Type	Description
callback	() => void	Function to run after this layer has been drawn and filtered.

Returns

void

Example

const layer = t.layers.add();

layer.draw(() => {
	t.background(0);
	t.char('A');
	t.rect(12, 8);
	layer.filter('grayscale', 0.4);
});

layer.postDraw(() => {
	layer.filter('invert');
});
