Hi,

I currently have an image I'd like to rotate (every 15°) to create a series of images I will use later on.

It would be nice to have that series in a single image.
I made a simple bash script that creates the 24 images, but would like to know how to do it in a single image and a single command if possible.

Code: Select all

convert -rotate "15" c.png c15.png

I also found this script, but it creates a gif file, and I'd like to keep a png:

Code: Select all

#!/bin/sh
#
# Create a rotating figure using Distort SRT transformations
#
command='convert -delay 10 c.png -virtual-pixel white'

for i in `seq 15 15 360`; do
  command="$command \\( -clone 0 -distort SRT $i \\)"
done

command="$command -delete 0 -loop 0 animated_distort_rot.gif"

eval $command

chmod 644 animated_distort_rot.gif

If you think it's possible, please let me know.

Thanks.

PNG does not support multi-frame images. GIF supports multi-frame images and animations. I believe you can save to TIFF also to have multipage images, but not animations. The imagemagick MIFF format can also be used, but only Imagemagick can view that.

So try

Code: Select all

convert c.png c.tif
for ((i=15; i<360; i=i+15)); do
convert c.tif \( c.png -background none -distort SRT $i \) c.tif
done

Again, this will not animate, but does contain every rotation angle in one file.

P.S. You can view the animation, using Imagemagick animate as follows:

Code: Select all

animate -delay 50 c.tif

Thanks a lot, Fred.
