Digital Illustration (RVP Mobile App)

While analyzing video, the app allows you to draw directly onto the video with your finger. A single finger is used to draw freehand, like using a pencil.

If you draw an approximate line or circle, your drawing will be converted into a perfect shape. If you draw an angle by drawing two separate lines, those lines will be combined into an angle shape with a degree measurement.

By default, you may use a two-finger touch to draw a line. This provides a very quick way to draw an angle--use a two-finger tap twice with your thumb at the vertex and your forefinger at each endpoint.

You may choose other two-finger shapes by touching the Tools icon in the upper-righthand corner. Choose from Line, Circle, or Box.

When Pan/Zoom is selected, using two fingers to move the image and to zoom-in on a particular region of the video. Using a single finger will draw freehand.

To undo your most recent drawing, double-tap the image or touch the Undo button. To erase all drawing from the screen, gently shake your Android phone or touch the Erase button. Using the "Disable Touch Delete" setting will force you to use the buttons within the menu to Erase/Undo drawings. This is helpful if you find yourself accidentally removing lines.

To move existing objects, touch the Tools icon and then select the Move tool. Orange handles will appear at locations which may be touched and moved. Using multi-touch controls, you are able to adjust the size/length of the existing drawings.

Illustrations on screen at the time you close the video analysis will be saved and automatically restored when you next analyze the video.
