Apps Kingdom sums it up: "This app transforms your pictures into amazing line sketches of amazing visual effects."
Just pick an image from your photo library or take a picture using the camera, and a sketch made of thin lines is immediately created for you. Have endless fun playing around with settings: Line width, intensity and color saturation and create your own piece of artwork.
Extremely easy to use. A handful of demo pictures are also included for a quick spin.
Proprietary algorithms generate great results with any type of image content.
