Growing image vertically/horizontally

[kirillt]

If we make user capable of growing image then they could do graphical notes using the app. Suppose that the user has a device supporting input with pen. The user can write on the image in drawing mode, but when they reach the edge they need more blank space to continue writing. We can grow space on scroll event or by pressing special floating button.

This UX problem could be solved also by vector graphics mode and infinite canvas.
