How do you create flash images on the fly at the server side?

The question just came up!

I have seen in web apps we get flash images generated on the fly how is it achieved开发者_运维技巧? Any api for programming languages (Java Python)?

PS: It's adobe flash movie / image or swf

If by Flash images you mean JPG, PNG and GIF files then you use any of the standard server side software packages or language specific libraries that utilize these packages.

Here are the two most popular:

ImageMagick

GD

Python has PIL (Python Imaging Library)

If you are referring to generating swfs then update the question and perhaps you can get some help on that too.
