An attempt at displaying GIF animations inside a sketch

[villares]

py5 can export GIF animations (check out py5_tools.animated_gif()) but how to draw an existing GIF inside your sketch?

This is an experiment (with lots of commented out print debugging lines) I tried some time ago.
I guess someone could try to make it a class mode thing so it becomes more robust and reusable, or add override options for the delay and looping...

import py5

"""
Demo: needs a GIF file named 'arvores.gif'!
"""
def setup():
    global gif
    py5.size(500, 500)
    gif = Py5Gif('arvores.gif') 
    
def draw():
    gif.draw(50, 50, 400, 400)

class Py5Gif():
    """
    A wrapper for loading and displaying GIF animation files.
    """
    default_delay = 100
    
    def __init__(self, gif_file_path):
        from itertools import count
        from PIL import Image

        if isinstance(gif_file_path, (py5.Path, str)):
            pil_img = Image.open(gif_file_path)
        else:
            raise TypeError('Provide the path to a GIF file.')
        self.loc = 0
        self.previous = 0
        self.delay = pil_img.info.get('duration', self.default_delay)
        self.frames = []
        try:
            for i in count(1):
                self.frames.append(py5.convert_image(pil_img.copy()))
                pil_img.seek(i)
        except EOFError:
            pass

    def draw(self, *args):
        if not self.previous:
            self.previous = py5.millis()
        elif py5.millis() - self.previous > self.delay:
            # print(py5.millis() - self.previous, py5.millis(), self. previous)
            self.loc = (self.loc + 1) % len(self.frames)
            self.previous = py5.millis()
        py5.image(self.frames[self.loc], *args)
        # print(self.loc)
        
if __name__ == '__main__':
    py5.run_sketch(block=False)

If you need a GIF to try out:
arvores.gif

Runs ok with Imported mode for py5.

I like this. Great way to incorporate a GIF into a Sketch. PIL is in awesome library for working with GIFs

The following is an alternate technique for playing a .gif inside a sketch. It utilizes a JavaFX imageView in a default Processing window. The .gif file may be loaded from your sketch folder.

# Uses Imported mode for py5

import java.io.FileInputStream
from javafx.scene.image import Image
from javafx.scene.image import ImageView

def setup():
  global inputFile
  size(800, 800, FX2D)
  window_title('JavaFX Button in Default Window')
  canvas = get_surface().get_native()
  root = canvas.getParent()  
  inputFile = java.io.FileInputStream("arvores.gif")
  myImage = Image(inputFile)
  imageView = ImageView(myImage)
  root.getChildren().add(imageView)

Output:
