How to add stroke/border to transparent png image in android?












1















I have transparent images like shapes,letters which I'm fetch from gallery so I need to give them stroke/outline with black color, I can set border but It's set to whole bitmap like left,right,top and bottom.




Same thing we can do with photoshop is giving outerstroke to image but I want to achieve that in android.




I tried this and this It's give border, But what I want to do is like below
sample image



Original Image
without stroke



I want like this -->
With stroke



Does this possible in android?






java android bitmap png android-canvas
