Building an animation using Python Gizeh -
i able create simple diagram shapes , numbers. using following code:
import gizeh gz w, h = 500, 300 surface = gz.surface(w,h, bg_color=(1,0.7,1)) in range(1,9): rect = gz.rectangle(lx = 10, ly = 10, xy=(w/a,h/a), fill =(0,1,0.7)) rect.draw(surface) txt = gz.text(str(a), fontfamily="dancing script", fontsize=15, fill=(0,0,0),xy=(w/a,h/a)) txt.draw(surface) surface.ipython_display() i have created version using moviepy:
import numpy np import gizeh gz import moviepy.editor mpy w, h = 500, 300 duration = 5 figpath = '/tmp/' fps = 1 def make_frame(t): surface = gz.surface(w,h, bg_color=(1,1,1)) rect = gz.rectangle(lx = 10, ly = 10, xy=(w/(t+1),h/2), fill =(0,1,0.7)) rect.draw(surface) txt = gz.text(str(t+1), fontfamily="dancing script", fontsize=15, fill=(0,0,0),xy=(w/(t+1),h/2)) txt.draw(surface) return surface.get_npimage() clip = mpy.videoclip(make_frame, duration=duration) clip.write_videofile(figpath + 'trax_0.mp4', fps=fps) clip.ipython_display(fps=fps, width=w, autoplay=0, loop=0) i able create animated gif using time delay between each step of cycle.
#!/usr/bin/env python3 import numpy np import gizeh gz import moviepy.editor mpy w,h = 128,128 # 128x128 pixel duration = 2 # 2 seconds ncircles = 20 # number of circles def make_frame(t): surface = gz.surface(w,h) in range(ncircles): angle = 2*np.pi*(1.0*i/ncircles+t/duration) center = w*( 0.5+ gz.polar2cart(0.1,angle)) circle = gz.circle(r= w*(1.0-1.0*i/ncircles), xy= center, fill= (i%2,i%2,i%2)) circle.draw(surface) return surface.get_npimage() clip = mpy.videoclip(make_frame, duration=duration) clip.write_gif("circles.gif",fps=15, opt="optimizeplus", fuzz=10)
