It's not clear to me which is the best way to convert a p5.graphics to a p5.Image.

At the moment i'm doing this:

var pg = createGraphics(400,400);
//do stuff inside pg
var img = createImage(pg.width,pg.height);
img.copy(pg, 0, 0, pg.width, pg.height, 0, 0, pg.width, pg.height);

I imagine there's a better way but i'm not able to figure it out.

That's probably the best way to do it.

My question is this, though: why do you need to create a p5.Image ? Is there something you're trying to do where using the p5.Graphics object directly doesn't work?

So the point is that i want to create a custom-shaped mask that follows the mouse and apply it to a graphic element.

My solution was to draw two p5.Graphics, one for the mask and one for the contents. The problem is that mask() is available only for p5.Images, therefore i have the need of converting it. Here is an example: https://alpha.editor.p5js.org/mikima/sketches/SkEXyPvpf

Probably this is not the simplest solution, in case would be great if you can point me in the right direction.

hi @mikima, thanks for reporting this! we recently moved to a new forum, here: https://discourse.processing.org/

it looks like you were able to find a solution, so I'm going to close this. hopefully the forum will be helpful in the future!

Thanks. It would be however useful to use mask() directly on p5.Graphics, or otherwise add a quick way to get a p5.Image from p5.Graphics objects.
