PixelAdjustor
Changes the color of individual pixels in a Bitmap
Usage
See the sample app. Typical usage:
PixelAdjustor.adjustColor(bitmap, Color.WHITE, Color.MAGENTA);#perfMatters
In the sample, we compare this library vs a native Java implementation. In some very basic testing with an image of 4096x2304, we are seeing the Java implementation take 1120 ms vs the native implementation taking 92ms.
NDK
NDK docs and support are hard to come by. These references have helped a lot in developing the NDK parts of this lib
