public interface BlurAlgorithm

Method Summary

Modifier and Type	Method and Description
android.graphics.Bitmap	blur(android.graphics.Bitmap bitmap, float blurRadius)
boolean	canModifyBitmap()
void	destroy() Frees allocated resources
android.graphics.Bitmap.Config	getSupportedBitmapConfig() Retrieve the Bitmap.Config on which the BlurAlgorithm can actually work.

Method Detail

blur

android.graphics.Bitmap blur(android.graphics.Bitmap bitmap,
                             float blurRadius)

Parameters:

bitmap - bitmap to be blurred

blurRadius - blur radius

Returns:

blurred bitmap

destroy

void destroy()

Frees allocated resources

canModifyBitmap

boolean canModifyBitmap()

Returns:

true if this algorithm returns the same instance of bitmap as it accepted false if it creates a new instance.

If you return false from this method, you'll be responsible to swap bitmaps in your blur(Bitmap, float) implementation (assign input bitmap to your field and return the instance algorithm just blurred).

getSupportedBitmapConfig

android.graphics.Bitmap.Config getSupportedBitmapConfig()

Retrieve the Bitmap.Config on which the BlurAlgorithm can actually work.

Returns:

bitmap config supported by the given blur algorithm.
