For anyone who's looking to do combine images into an animated GIF using Python3/Wand/ImageMagick, here is the code I'm using:


import sys

from wand.image import Image
from wand.api import library

def main(filenames):
with Image() as gif:
print(f"Adding {len(filenames)} frames...")
for ...

Excellent! This is working for me both in my C program and my Python program (I was able to get Wand working with ImageMagick 7).

I confirmed that setting the iterations on the first image also works:

MagickSetIteratorIndex(wand, 0);
MagickSetImageIterations(wand, 1);

Though I can't imaging ...

I was using IM v6.9.6-8 (because the Python library, Wand, has not been updated to support 7), so I installed IM v7.0.7-28. I'm still not seeing MagickSetImageIterations take effect. I'm on macOS, building with homebrew, and viewing the GIF in Firefox v59.0.2 as well.

Here's my latest code ...

I added MagickSetImageIterations to both my test program and the "bunny" example program, but unfortunately there's no change to either GIF.

I added printf("%lu\n", MagickGetImageIterations(aw)); after the MagickSetImageIterations line, and confirmed that iterations are set to 1, but the GIFs still ...

I just tried taking the bunny.c example (https://www.imagemagick.org/MagickWand/bunny.htm) and changing to , but it is generating a looped GIF still.

I'm working on a project and need to combine a directory of PNGs into an animated GIF. So far my code is working fine, except none of the MagickSetOption calls seem to be taking any effect. I wrote a very basic C program (my full project is in Python, using Wand to interface with MagickWand) to read ...
