Resize HTML canvas with respect to inner content

+4
−0

I am currently making an esoteric language which requires a theoretically infinite canvas. Basically, it should be able to resize and fit the contents of the drawing in and outside it's existing boundaries.

Black Squiggle, Red outline rectangle and brown solid rectangle

The brown region indicates the original canvas boundaries. The black lines are the drawing, and the red boundary is what it should expand to.

When I tried searching about this, all I got was things relating to using the <canvas> tag in a responsive layout.

How do I achieve this effect using the HTML <canvas> element?

How is the drawing stored in the background? (or more specifically: would you be able to give me only a part of the full image?) Do you want to be always able to see the whole image (shrink-to-fit) or would it be sufficient to "scroll" to see the area outside of the original canvas?

I think the main idea is 1) scrolling to the top leftmost position ,b) resizing the canvas to fit the whole image and c) redrawing everything back onto it. I need the whole drawing to be visible.
