Workaround for large images exceeding the maximum canvas size?

[nsitu]

I am considering the limitations of canvas and how they apply to merge-images. Does any workaround exist in order to merge two very long images, in cases where the result would exceed the maximum length of a canvas (typically 32,767 pixels)?

Excuse me, have you achieved it? I also have this need。

I found a solution for my particular use case but it does not involve canvas. (I decided to use a server-side approach). If I was returning to this as a client side problem, I might explore using web assembly versions of various graphics libraries (Eg GraphicsMagick, FFMpeg, OpenCV, etc) and see if there are any similar limits
