Adobe has discontinued the creativeSDK Image Editor UI
This solution appears to no longer be viable. Sorry :(
Adobe deprecation announcement
Previous answer:
Aviary (acquired by Adobe) offers a free feature-rich on-page editor called Feather. It is hosted, however, in that you must perform a GET to retrieve the final full-size edited image. It's features include:
- enhance (new): Autocorrect your photo with one of four basic enhancements.
- effects (new): Choose from a variety of effects and filters for your photo.
- stickers: Choose from a variety of stickers you can resize and place on your photo.
- orientation (new): Rotate and flip your photo in one tool.
- resize: Resize the image using width and height number fields.
- crop: Crop a portion of your photo. Add presets via API. Fixed-pixel cropPresets perform a resize when applied (new).
- brightness: Adjust the overall image brightness.
- contrast: Adjust the overall image contrast.
- saturation: Adjust the overall image saturation.
- sharpness (new): Blur or sharpen the overall image in one tool.
- draw: Add doodle overlays with a brush.
- text: Add custom, resizable text.
- redeye: Remove redeye from your photo with a brush.
- whiten: Whiten teeth with a brush. (Not supported in IE7-IE8)
- blemish: Remove skin blemishes with a brush.
I'm currently integrating it in a site and there are a few gotchas (they might be my fault.) I can't ever get it to perform a POST callback to my URL with the finished image URL, so instead I use the objects .onSave handler which provides the same info. Also, in current chrome/firefox, there is a security exception when Feather modifies canvas data directly from your site. So instead provide the url
option (causing Feather to request the image at that URL and then provide it back to the widget on your page.)
