I'm trying to make a blinking box with imagemagick
convert -loop 1 -delay 500 -dispose Background lightOn.png lightOff.png blink.gif
result is just the first image.

Ezgif.com is a great page but can ImageMagick get the same results?
Ezgif settings:
Delay: 200 per image
Crossfade frames
Fader delay: 6
Frame Count: 10
My attempt via Linux Terminal:
convert -delay 200 -loop 0 *.jpg myimage.gif
As i told you on FL, you need to simply use
convert -resize (Smallest size) -delay 200 -morph 200 (source) (destination)
e.g:
convert -resize 200x200 -delay 200 -morph 200 /var/home/user1/pictures/*.jpg /var/home/user1/myresult.gif
on my side i can show you the result like this used on WINDOWS
in Windows Pictures folder
used this command:
C:\Users\Public\Pictures\Sample Pictures>convert -resize 20% -delay 20 -loop 0 *.jpg -morph 5 myimage.gif
Here is Unix shell script to create a faded animation of 4 images each with 10 intermediate fades. It loops over each successive pair of images and creates the faded intermediate images by blending the pair at different percentages.
Input:
(
imgArr=(lena.jpg mandril3.jpg zelda1.jpg peppers.jpg)
for ((i=0; i<4; i++)); do
img1=${imgArr[$i]}
j=$((i+1))
jj=$((j%4))
img2=${imgArr[$jj]}
for ((k=0; k<11; k++)); do
pct=$((10*k))
convert $img1 $img2 -define compose:args=$pct -compose blend -composite miff:-
done
done
) | convert -delay 20 - -loop 0 anim.gif
Animation:
Note that I had to shrink the image to 75% dimensions to make the file size small enough for upload here.
A complete one-liner solution with increased delay for main frames and last-to-first transition, with the same settings OP asked:
convert -loop 0 *.jpg -morph 10 -set delay '%[fx:(t%11!=0)?6:200]' -duplicate 1,-2-1 out.gif
-morph 10 inserts 10 intermediate frames between every original frame, so we need to increase the delay time for every 11th frame, so the fx part sets different delay time for them.
-duplicate 1,-2-1 does the transition for last to first frame
I am trying to make a gif with images using convert. But in the resulting gif, the images are just stacking one over the other.
Here is the created gif : https://i.imgur.com/EgISW2y.gif
I tried creating it with simple command :
$ convert -delay 8 -loop 0 plot_* result.gif
Try using the -dispose setting with previous option, which disposes the previous frames after they are displayed:
convert -dispose previous -delay 8 plot_* -loop 0 result.gif

I am trying to stitch together a bunch of .png's which contain some alpha (transparency) but which have a uniformly white background. The png's look fine individually, but in the resulting .gif some frames acquire a patchy background that appears to have the same RGBA color as some of the points being animated.
I have tried the following commands
convert -delay 1 im*.png anim.gif
convert -delay 1 -alpha set im*.png anim.gif
convert -delay 1 -alpha set -dispose background im*.png anim.gif
convert -delay 1 -alpha set -dispose previous im*.png anim.gif
convert -delay 1 -alpha set -dispose previous -background white im*.png anim.gif
pretty much just trying additional flags to see if anything happens to fix the glitch, but I get the same behavior in every case. Anyone have a fix?
Ah, this question led me to the right answer --
convert -delay 1 -layers Optimize im*.png anim.gif
works!
I want to make an animated gif from those .png image:
I do it with this command:
convert -layers OptimizePlus -delay 25x100 ps1-*.png -loop 0 ps1.gif
It made an animated gif successfully, however, the output has very low quality and smaller than input images:
After some search, I got -quality
convert -layers OptimizePlus -delay 25x100 -quality 99 ps1-*.png -loop 0 ps1.gif
But it seems like imagemagick just ignore the parameter.
The problem is that your source PNGs have an alpha channel which is not supported by GIFs. So you have to remove transparency from your source images first. Since you're dealing with multiple source images, you can't use the -flatten method. With newer ImageMagick versions the following should work:
convert -background white -alpha remove -layers OptimizePlus -delay 25x100 ps1-*.png -loop 0 ps1.gif
If your version of ImageMagick is older than 6.7.5, you can try:
convert -bordercolor white -border 0 -layers OptimizePlus -delay 25x100 ps1-*.png -loop 0 ps1.gif
I got the following result with the latter command:
I have an animation as a batch of .png files (100 files). The background is transparent in the source .png files. I want to convert them into a single animated gif. I have tried this command:
convert -delay 0 -loop 0 -alpha set *.png ani.gif
But the result is the following (green is the HTML page background):
How should I remove the previous frames from an every following one?
I've found -dispose previous.
UPDATE
OK, convert -delay 0 -loop 0 -alpha set -dispose previous *.png ani.gif
The solution is here:

The magic keyword seems to be “dispose” and calling the following fixed the problem:
convert -dispose 2 screencapture-*.tga screencapture.gif
