change brightness and contrast of canvas with marvinj

[Skyer Walker]

I did some search but can seen to find a way to use marvinj to do brightness and contrast, is this feature not part of the js solution? if not could you recommend a js framework that can do this? I am building an online photo editing app. thanks!

Yes, it is.

Marvin.brightnessAndContrast(imageIn, imageOut, brightness, contrast);

Example:

Marvin.brightnessAndContrast(image.clone(), image, 10, 0);
