textmode.js / Textmodifier / finalDraw

Method: finalDraw()

finalDraw(callback): void;

Set the final post-processing callback for the composited output.

This callback runs after all visible layers have been composited and after global filters queued via filter during normal draw callbacks have been applied. Filters queued with t.filter() inside this callback are applied to the final composited texture before it is presented to the canvas.

Use postDraw when you want to affect only the base layer. Use this method when you want to affect the final image made from all layers.

Parameters

Parameter	Type	Description
callback	() => void	Function to run before the final texture is presented.

Returns

void

Example

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

t.finalDraw(() => {
	t.filter('invert');
});
