Drawing Operations
The Draw module contains nodes used to draw on images. These nodes can be found under the opsi-draw tab.

BitwiseAND¶

Uses a mask to select and output only the pixels of the input img that are white on the mask input. These pixels are taken and put to an output img, with the rest of the pixels being black.
DrawContours¶

Takes an image img and draws the input contours onto the image.
DrawFPS¶

This node draws the number of frames per second of onto the top left of input img and outputs the updated image.
