Photo - Black and White Sketch

This app simply creates a Black and White Sketch of any photo you want. The algorithm used converts pixels above a threshold level of brightness as white and pictures below the level of threshold brightness as black. In order to select a photo click on Add Photo and select Image from Gallery. Use the slider for adjusting threshold. Adjusting threshold helps define which areas are shaded white and which areas are shaded black. This makes it possible to customize the Black and White Sketch of the Photo. Image can be flipped and rotated for convenience. Black and White Pixels can be inverted to create a negative sketch of the photo. In the end the sketch can shared as a jpeg image using any of the sharing apps like Whatsapp, Gmail, Email or Facebook
