Hello everyone,

first of all, thanks for reading this. Second, sorry for any mistake I do in this post, english isn't obviously my native language.
Going to the point, i would like to generate an animated image from a single image.
Explaining it further, imagine you have a huge image, like 4000x1080 and I just want the animation start from the left in a standard HD (1920x1080) and then go smoothly to the right.
Any ideas?

Thx for any reply

You don't say what version of IM you are using nor what platform.

Basically you create a loop to subsection the images, set the delay and loop and add each new subsection as a new frame to the animation. There may be more elegant ways to do this, but this should give you the basic idea. I am not an expert on animations.
Note that -crop could be used in place of the [...] subsection concept.

For unix, try this example

infile="logo:"
ww=`convert $infile -format "%w" info:`
sub=100
convert logo:[${sub}x${sub}+0+0] +repage animation.gif
xoff=100
while [ $xoff -lt $((ww-sub)) ]; do
convert -delay 50 animation.gif ${infile}[${sub}x${sub}+$xoff+0] +repage -loop 0 animation.gif
xoff=$((xoff+sub))
done

If you want the pieces to move across a white background, then remove the +repage from both places and add -dispose previous and -background white.

infile="logo:"
ww=`convert $infile -format "%w" info:`
sub=100
convert logo:[${sub}x${sub}+0+0] animation.gif
xoff=100
while [ $xoff -lt $((ww-sub)) ]; do
convert -background white -dispose previous -delay 50 animation.gif ${infile}[${sub}x${sub}+$xoff+0] -loop 0 animation.gif
xoff=$((xoff+sub))
done

Let us know if either of these are what you want or how you need it changed.

If on Windows, then see http://www.imagemagick.org/Usage/windows/. Unfortunately, I am not a Windows user, so cannot help in converting the syntax.

Hi! Thanks for the reply, mate.
I was planning to run all the code that you replied in a bash script. I'm using Ubuntu 10.4 with ImageMagick 6.6.2-6 2011-03-16 Q16.
Thanks for the code, but i dunno what to do with it! A bit newbie here. Is it PERL or something?

Ok, i figured it was a bash script (Sorry for dumbness) and it worked perfectly. Thanks a lot, mate!

By the way, the code ended like this when I adjusted the params:
