Hello Helge, I just tried to collect some information for the Maintainer.
Might this be the expected behaviour? This image seems to have a stored Delay and Duration value: $ identify -verbose 2006_08262.gif Image: Filename: 2006_08262.gif ... Delay: 20x100 Duration: 20 ... These 20 get get read here: (rr) bt #0 0x00007fcdf0974404 in ReadGIFImage (image_info=<optimized out>, exception=<optimized out>) at ../../coders/gif.c:1098 #1 0x00007fcdf0717c20 in ReadImage (image_info=image_info@entry=0x558dfa3c9680, exception=exception@entry=0x558dfa3c4c10) at ../../magick/constitute.c:563 #2 0x00007fcdf05ce223 in DisplayImageCommand (image_info=0x558dfa3c9680, image_info@entry=0x558dfa3c54e0, argc=<optimized out>, argc@entry=2, argv=<optimized out>, argv@entry=0x7fff189926b8, wand_unused_metadata=wand_unused_metadata@entry=0x0, exception=exception@entry=0x558dfa3c4c10) at ../../wand/display.c:492 #3 0x00007fcdf0616f80 in MagickCommandGenesis (image_info=image_info@entry=0x558dfa3c54e0, command=0x7fcdf05cd5b0 <DisplayImageCommand>, argc=argc@entry=2, argv=argv@entry=0x7fff189926b8, metadata=metadata@entry=0x0, exception=exception@entry=0x558dfa3c4c10) at ../../wand/mogrify.c:173 #4 0x0000558df995d0fa in DisplayMain (argv=0x7fff189926b8, argc=2) at ../../utilities/display.c:89 #5 main (argc=2, argv=0x7fff189926b8) at ../../utilities/display.c:100 And get interpreted here, resulting in a delay of 0: 14934 delay=display_image->delay/MagickMax(display_image->ticks_per_second,1L); (rr) bt #0 XDisplayImage (display=display@entry=0x558dfa3c17f0, resource_info=resource_info@entry=0x7fff18991270, argv=0x558dfa3c15b0, argc=2, image=image@entry=0x7fff18990a50, state=state@entry=0x7fff18990a48) at ../../magick/display.c:14935 #1 0x00007fcdf05cfaa7 in DisplayImageCommand (image_info=0x558dfa3c9680, image_info@entry=0x558dfa3c54e0, argc=<optimized out>, argc@entry=2, argv=<optimized out>, argv@entry=0x7fff189926b8, wand_unused_metadata=wand_unused_metadata@entry=0x0, exception=exception@entry=0x558dfa3c4c10) at ../../wand/display.c:538 #2 0x00007fcdf0616f80 in MagickCommandGenesis (image_info=image_info@entry=0x558dfa3c54e0, command=0x7fcdf05cd5b0 <DisplayImageCommand>, argc=argc@entry=2, argv=argv@entry=0x7fff189926b8, metadata=metadata@entry=0x0, exception=exception@entry=0x558dfa3c4c10) at ../../wand/mogrify.c:173 #3 0x0000558df995d0fa in DisplayMain (argv=0x7fff189926b8, argc=2) at ../../utilities/display.c:89 #4 main (argc=2, argv=0x7fff189926b8) at ../../utilities/display.c:100 (rr) print display_image->ticks_per_second $11 = 100 (rr) print display_image->delay $12 = 20 (rr) next 14935 timer=GetMagickTime()+(delay == 0 ? 1 : delay)+1; (rr) print delay $13 = 0 https://sources.debian.org/src/imagemagick/8:6.9.11.60+dfsg-1.3/magick/display.c/#L14934 One could modify the delay to e.g. 1000 centiseconds == 10 seconds: time display-im6.q16 -delay 1000 2006_08262.gif I am not sure how this "Delay" and "Duration" is expected to be interpreted (or ignored?) for a GIF with just one picture.
