indicating the passage of time in a file.gif

[Federico P]

Hello everybody,

I run a simulation of an Astrophysical problem and et the end i've a lot of file.png .
So i decided to create a file.gif with the following command :

Code: Select all

 convert -delay 20 -loop 0 rho.*.png animation.gif 

Now i want to put some object that indicates the passage of time in my gif. Is it possible to do this ???????

Something like a clock or the time from the photo EXIF data?

something like the bar to the right of this movie:

or the time to the right, on the top of this gif:

just compute the time using the frame number and the delay, then label your image with that number. You may have to write a loop to do the labeling from the individual (-coalesced) frames knowing how much delay you are using or going to use to regenerate the animation.

This one shows you how to add a label under your frames:

Try this:
convert -delay 100 rose: rose: rose: rose: -loop 0 rose.gif

convert rose.gif -coalesce \
-gravity South -background white -splice 0x18 \
-annotate 0 'Time %[fx:t*100]' \
-layers Optimize rost_labeled.gif

Thanks so much for your answer. I used your command and I finally do my work.

Thanks so much, really.
