I've been using android's RenderScript for about a month and I can't figure out, how I'd change a contrast with it.
I've been able to change Brightness, Blur, and Saturation, but I'm stuck with Contrast and Hue.
I know that it's possible to change contrast with histogram equalization and there's a ScriptIntrinsicHistogram class but I can't figure out how to achieve this.
Thank you for your responses.
