December 3, 2009 - This is probably my last update to the script for awhile; however, I'm really pleased with the additions.
The new script works in the same fashion as before, but now you can add snow to an existing animation (convert it to an RGB type first - Image Menu > Mode > RGB) or you can export the snow layers to separate images for additional processing in other programs or in GIMP GAP.
You can also set the snowflake size and blur the flakes.
Make sure you delete your previous script if you had it installed to avoid conflicts.
Just in time for Christmas! Here's a script that will let you take any background image (must be RGB type) and turn it into an animated snowfall. The script is based on my tutorial here: [link]
There are no limitations on using it....just have fun. A note would be nice, but a fave would be even better!
Installation Instructions
Click on the Download link to save the zip file. Once saved to your computer, double-click the zip file to open. There are several files inside:
AnimatedSnow.scm (this is the script file) A "Read Me" file with instructions and some sample images
Copy and paste the AnimatedSnow.scm file to your GIMP Scripts folder: C:\Program Files\GIMP-2.0\share\gimp\2.0\scripts
If GIMP is open, go to Filters > Script-Fu > Refresh Scripts so that GIMP will recognize the script. If GIMP isn't open, open it.
Open up the image you would like as your background and go to Filters > Animation > Animated Snow... and set the parameters (see additional instructions in the "Read Me" file.
Save as an animated gif. Keep in mind that large images with lots of frames = BIG file sizes!
Type the name of your picture in, adn after the name you just set .gif
