Error at creating GIF Image with ImageMagick: too many exceptions and blinking problem

I have a directory with a lot of png files with the next structure:

image1.png
image2.png
...
image3372.png

I am trying to create a GIF image with ImageMagick, so in a Terminal I am typing:

sudo apt-get install imagemagick
convert -delay 0.01 -loop 0 *.png myimage.gif

But I have the next errors:

...
convert-im6.q16: DistributedPixelCache '127.0.0.1' @ error/distribute-cache.c
/ConnectPixelCacheServer/244.
convert-im6.q16: cache resources exhausted `Image119.png' @ error/cache.c/OpenPixelCache/3984.
convert-im6.q16: too many exceptions (exception processing suspended).

And the GIF created is not complete: enter image description here

Also, it blinks. I think it is because it is considering image18 and image180 as consecutive. How do I fix that?

I am running Ubuntu 18

  1. 100 frames/second is overkill. You can run with 10 frames/sec and divide the image count by 10 (or at least the standard 25 frames/sec and divide by 4).
  2. *.png is expanded and sorted alphabetically by your shell,so if you want frames in their number sequence, pad the names with 0's:
for n in {1..3372} ; ; do mv image$n.png image$(printf "%04d" $n).png ; done
  1. convert (and other IM commands) uses a memory cache and has several self-enforced limits (that you can list with IM's identify command):
>>> identify -list resource
Resource limits:
  Width: 16KP
  Height: 16KP
  List length: 18.446744EP
  Area: 128MP
  Memory: 256MiB
  Map: 512MiB
  Disk: 1GiB
  File: 768
  Thread: 8
  Throttle: 0
  Time: unlimited
  • You can boost the limit for one run:
convert -limit memory 1000  ...
  • For more permanent changes you can also edit /etc/ImageMagick-6/policy.xml and look for lines such as <policy domain="resource" name="memory" value="256MiB"/> and increase the necessary ones.
