textmode.js / Textmodifier / postDraw

Method: postDraw()

postDraw(callback): void;

Set the base layer post-draw callback.

This callback runs after the base layer's draw callback, ASCII resolve pass, and any filters queued on the base layer during draw. Filters queued on t.layers.base inside this callback are applied to the base layer before other layers are composited on top.

Calling this method is equivalent to setting the callback on textmodifier.layers.base:

textmodifier.layers.base.postDraw(callback);

Parameters

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

Returns

void

Example

t.draw(() => {
	t.background(0);
	t.char('A');
	t.rect(12, 8);
	t.layers.base.filter('grayscale', 0.5);
});

t.postDraw(() => {
	t.layers.base.filter('invert');
});
