I just launched a new rails app that might just save you some dealing with vector-based graphics. Well for now it only does simple gradients and corners, but I’ve still found it useful.
Basically, instead of generating the image in Photoshop/GIMP and then referencing that file in your CSS/HTML, you just put the parameters in the url and the images are generated for you. A quick find and replace can change your color scheme without needing to go back to Photoshop/GIMP.
You will need to send me an email if you want to sign up. I think it is safer to start with a small beta.
Note: pretty much everyone on this mailing list is smart enough to ‘hack’ the access_key, so that you don’t have to sign up for the beta. I am just going to ask that you please not do it. I will be fixing that soon, but in the meantime it isn’t a serious security hole so I’m just going to ask everyone to be nice. If you want to try it just send me a note, and I’ll set you up.
I am really looking forward to hearing what you think.
