Is an immutable Bitmap faster then a mutable one?

The Bitmap class has a method copy() with the signature below:

public Bitmap copy(Bitmap.Config config, boolean isMutable)

Is there a performance difference between a mutable and an immutable Bitmap?

How do you make a bitmap mutable?

Options options = new BitmapFactory. Options(); options. inMutable=true; myBitmap=BitmapFactory. decodeFile(filePath,options);

How to create Bitmap in android?

To create a bitmap from a resource, you use the BitmapFactory method decodeResource(): Bitmap bitmap = BitmapFactory. decodeResource(getResources(), R. drawable.

What is the use of bitmap in Android?

A bitmap is simply a rectangle of pixels. Each pixel can be set to a given color but exactly what color depends on the type of the pixel. The first two parameters give the width and the height in pixels. The third parameter specifies the type of pixel you want to use.

To answer the original question: no, there is no performance difference. There are some optimizations we could implement for mutable bitmaps though. Hopefully in a future release :)
