How = can I achieve multipage metapost output from ConTeXt? The result should = be a multipage pdf. It contains just a metapost graphic per page. The = graphic has always the same bounding box and evolves from page to page: = Some elements to be drawn are added, and some others would ideally also = be removed, while keeping elements which has already been drawn on = previous pages. I can manage when it is not possible to remove elements = (in that case I'll just cover them with a covering element). =

I saw that it is possible to achieve my goal with = standalone metapost, as described here: https://tex.stackexchange.com/questions/471662/mpt= opdf-is-multipage-output-pdf-possible
But I'll need to = achieve this with Metapost inside ConTeXt because I use labels in = Metapost which print text in Japanese, Korean , Arabic and Roman script: = Thanks to ConTeXt, I can define appropriate fonts for each script. All = this works already in my working example.

The only = unsolved problem is to ship out multiple pages.

For the = minimal working example, I didn't remove the font defining part, because = having 4 different fonts is a condition of my use case. The graphic on = the other hand is some simple dummy nonsense graphic not from my = project. The graphic is in the provided example drawn as a summing up of = layered drawing steps (6 steps, to be precise), so no removing is = implemented here (because I don't know how that would be done). If each = of the figures 1 to 6 of my mwe can be put alone on a page, I'd be = already very happy. Now, they're put on top of each other all on the = same single page, also on top of figure 0.

The desired = multipage pdf will be used in presentation mode of a pdf viewer and = skipped forward and backward from page to page (that is from drawing = step to drawing step).
