Generating CSS sprites for dynamic images
css, css-sprites, html, sprite
Solution
You can check and try jawr (https://jawr.dev.java.net/) library for generating/modifying (also compressing, merging) css files on servlet. It has option to change background images dynamically. You may arrange bundles for switching css file(s) for changing skin(s).
Plus side: You can also manage and arrange your .js files too!
Problem
I have a webpage which contains about 20 - 50 dynamic images (images served from a non-static source). These images are served through a servlet based on the request URL. This results in a request being generated per image, which leads to performance decay. If these images were static, I would create a CSS sprite and replace the 50 requests with a single one. As they are dynamic this is not that easy of course. I'm looking for a tool/library/method that I can use in order to aggregate these images into a single sprite at runtime. Luckily image size is constant and the same for all, which should make this much easier. Any suggestions?
