I want to play 3 pictures repeatedly for 10 times in a gif. How do I compress the size of gif using magick?
convert -delay 100 -coalesce -layers Optimize 0[123].png 0[123].png 0[123].png 0[123].png 0[123].png 0[123].png 0[123].png 0[123].png 0[123].png 0[123].png out.gif
The gif generated by the above code does not seem to compress the repeating frame, just simply superimpose the image.
The -loop option cannot be used because the playback device can only play gif once.

I am creating preview images of all JPG/PNG/GIF that are uploaded to our server.
For this I use ImageMagick with:
convert -format jpg -quality 90 -strip -background white -flatten -alpha off +repage -resize '255x255>' ".$locationtmp." -write '".$preview."'");
The parameters added are to flatten the background (make it white instead of black).
However, when using the code to create a preview of an animated GIF, the result is distorted.
Example of a distorted result:
I tried to add the +repage parameter but it did not help.
How to get a nice preview of the GIF as PNG? It could also be just the first frame.
In Imagemagick, if you want a preview image for all formats including gif and want just the first frame of the animation for the preview, then just add [0] to the filename, such as animation.gif[0]. This will take the first frame of the animation and the only frames of the other formats such as JPG and PNG that only allow one frame. The appended [0] does not hurt the other formats.
So use
image.suffix[0] in place of just image.suffix
for generating a single image preview
I am trying to change the background layer of a batch of png images to include a moving gif. I'm running on MacOs and imagemagick version 7.1.0-19.
There are two types of images I want to merge:
Overlay static images A*.png
Background image Moving#40.gif
The background gif takes 120 frames.
So far I have managed to build the images and create GIFs. However the animated gifs are not moving. I have tried including delay and loop but this does nothing. The code is as follows:
magick mogrify -format gif -delay 10 -draw 'image Dst_Over 0,0 0,0 "Moving#40.gif"' A*.png -loop 0
I have been looking for days for similar use cases but have not found a solution,I just recently got into ImageMagick so advice is much appreciated.
any ideas on how this can be accomplished?
One way would be to process them one at a time in a script loop, since one is a gif animation. Then you would use a null: separator and -layers composite. For example for one PNG.
Transparent PNG:
Animation:
magick logot.png null: \( glitter.gif -coalesce \) -gravity center -compose dstover -layers composite -layers optimize result1.gif
See https://legacy.imagemagick.org/Usage/anim_mods/#composite
Alternately, you can use -draw, but in the reverse with the png inside -draw and the GIF after magick.
magick glitter.gif -gravity center -draw 'image Over 0,0 0,0 "logot.png"' -layers optimize result2.gif
I have an animation from Blender rendered as 500 .png images, I want to convert these 500 images into a single looping .gif file, the images are 1080x1080. How do I convert them while keeping a high quality image?
convert -size 1080x1080 -delay 2 -loop 0 *.png output.gif
Without the -size flag I was getting artifacts for some reason trying to convert *.png output.gif this works,
I have a bunch of files labelled 1.png and so on. I'm using the following command line to produce a gif animation:
convert -delay 20 *.png animation.gif
But the frames get superposed sequentially. I did not expect this behavior, what might be wrong?
Thanks
Option -dispose previous:
convert -dispose previous -delay 20 *.png animation.gif
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:
