Create image from pixel data?

[esrix]

I was wondering if there was a way to create an image in RenPy from pixel data already in computer memory? For example, if I were to pass RenPy an array of pixel data from a PyGame surface, could I construct an image from that pixel data and use it for a background in RenPy?

Reason is I've got an idea for a game that I can execute the mechanics with in PyGame, but I'd really like for RenPy to handle the storytelling elements. So I'd like to be able to take a screen capture of the game in PyGame and set it as the background in RenPy--essentially faking the appearance of a seemless transition from gameplay to story events.

Hm, you can create a custom displayable and blit the surface.

Code: Select all

init python:

    class PyGameSurface(renpy.Displayable):
        
        def __init__(self, surface):
            renpy.Displayable.__init__(self)
            
            self.surface = surface
            
        # Render the displayable
        def render(self, width, height, st, at):
            r = renpy.Render(width, height)
            # we don't need to render the surface, since... well, it's already a SDL surface =D
            # so, just blit it
            r.blit(self.surface, (0, 0)) 
            return r
            
        # Redraw this at each interact
        def per_interact(self):
            renpy.redraw(self, 0)

Sweet. I'll have to give this a try.

Thanks!

You can't store a pygame surface inside a displayable if you want to save the displayable. Just pointing that out.

Is there a way to convert an array to a surface that the displayable can use?

Not that I'm willing to support in Ren'Py.

I guess you could just save a temporary image in the disk and use im.Image to this, so there wouldn't be any problems with the save/load thing. Not sure if it's the best thing to do anyways, but should work.

True... Perhaps pygame.image.save will do the trick. I'll take a look at it over the weekend.
