I have wanted to add basic effects to Cropper’s output for a while now. Effects you may see in photo galleries that should not require the use of a full fledge graphic apps to produce, especially for repeatable, common effects like drop shadows or outlines.

I think subtle effects like these help your image stand out when you are trying to convey a message. Documentation for example can have a more polished look with a few subtle effects on an image that help it stand out.

The effect filters are applied using a separate interface and before being sent to the output plug-ins. This also makes it easier to create this type of plug-in, since you do not need to code the saving of the image. 

Here is a capture and thumbnail using two early effect filters applied, outline and dropshadow. The effects may be chained together to apply multiple effects to an image before it is saved.

I was hoping to get some feedback on how you may want to use the filters. I had some ideas such as an ability to output two thumbnails per image, for instance one with dropshadow and the other with gray-scale and dropshadow, possibly for use as roll-overs in an application.

Since I am still finalising the interfaces, it would be nice to get as many features in as I can.
