I'd like to display an animated GIF or any other image in a pane in tmux.
I'm playing with asciimatics to do this, and have modded one of the sample programs (images.py) to:
- display a single image
- show no error messages on "Ctrl+C"
- accept a single command line arg "image filename"
Here's the script I have and the only issue is that it seems to do a slow refresh of the image being displayed ~ every 10 seconds. How do I remove this refresh, since the image is a static image?
image.py
from __future__ import division
from asciimatics.effects import BannerText, Print, Scroll
from asciimatics.renderers import ColourImageFile, FigletText, ImageFile
from asciimatics.scene import Scene
from asciimatics.screen import Screen
from asciimatics.exceptions import ResizeScreenError
import sys
total = len(sys.argv)-1
if (total < 1):
print ("Usage: IMG")
sys.exit(1)
# Parsing args one by one
IMG = str(sys.argv[1])
def demo(screen):
scenes = []
effects = [
Print(screen,
ColourImageFile(
screen, IMG,
screen.height-2,
uni=screen.unicode_aware,
dither=screen.unicode_aware),
0,
stop_frame=200
)
]
scenes.append(Scene(effects))
screen.play(scenes, stop_on_resize=True)
# capture ctrl+c and exit nicely
import signal
import sys
def signal_handler(sig, frame):
sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
if __name__ == "__main__":
while True:
try:
Screen.wrapper(demo)
#Screen.wrapper(demo, catch_interrupt=True)
sys.exit(0)
except ResizeScreenError:
sys.exit(0)
