How to use it

Colorbar

Display Colorbar

colorbar = Colorbar()                                                     # Create an instance of Colorbar
bar_matrix = colorbar.get_cm()                                            # Get matrix
cv2.imshow('color_bar_demo', cv2.cvtColor(bar_matrix, cv2.COLOR_HSV2BGR)) # Display colorbar

Colorstrip(slider)

colorstrip = Colorstrip(conf)                                             # Create an instance of Colorstrip
colorstrip.connect(colorbar)                                              # Bind colorstrip to colorbar

colorstrip.slide(x)                                                       # Make the strip slide to x
bar_matrix = colorstrip.get_cm()                                          # Get matrix which contains colorbar and colorstrip
cv2.imshow('color_bar_demo', cv2.cvtColor(bar_matrix, cv2.COLOR_HSV2BGR)) # Display colorbar and colorstrip

colorpin = Colorpin()                                                        # Create an instance of Colorpin
colorpin.connect(colorboard)                                                 # Bind colorpin to colorboard

colorpin.locate(x, y)                                                        # Put the pin to (x, y) in colorboard
board_matrix = colorpin.get_cm()                                             # Get matrix which contains colorboard and colorpin
