Feature Request: Output Filters about imagine HOT 7 CLOSED

you are correct, I don't believe that caching using a filter is possible, nor that it should be done that way. I can help you implement your caching if something necessary for that is missing in the library.

It would be nice to hear your idea about caching image versions. To be able to cache them properly I'll need to know the options applied to the image operation so that I can check if an image created based on these operations was already created or not. I can simply wrap Imagine in another class that does that but I think it would be nice if Imagine would provide an interface for that somehow.

You could have a CachedImage class, that is a ImageInterface proxy. Then you'd interact with it like with a regular image and it would do cache lookups and population. Imagine already is interfaced so implementing a proxy shouldn't be a problem.

Ok sounds like a good solution I'll check it out as soon as I have time for this task again, thank you. You might want to update the manual with a chapter about how to cache images because I think this is a common task when dealing with images.

@burzum are there any news relating your caching feature? I'm interested in this too. @avalanche123 I think a CachedImage class in the core would be very useful, because no one wants to do expensive computations like reflections on every reload unless the source image or source data for charts have changed - that's simply not necessary.

@krnlde No, I've solved this on app level using a storage engine and this method https://github.com/CakeDC/Imagine/blob/master/Model/Behavior/ImagineBehavior.php#L88 to cache the images. I'm working on a private project and might write a blog article in a few weeks about it including the code as a follow up to this one here http://cakedc.com/florian_kraemer/2012/02/03/image-saving-and-processing-for-high-traffic-sites

But I still wish imagine would provide some kind of interface like paramsAsFilestring() and a way to use your custom storage engine with it.

Thanks @burzum !

+1 for the interface. If that is implemented I could use Assetic for caching, which would be awesome!
