c = color(20, 75, 200) # Define color 'c' fill(c) # Use color variable 'c' as fill color rect(15, 20, 35, 60) # Draw left rectangle greenValue = green(c) # Get green in 'c' print(greenValue) # Print "75.0" fill(0, greenValue, 0) # Use 'greenValue' in fill rect(50, 20, 35, 60) # Draw right rectangle | ||
| Description |
Extracts the green value from a color, scaled to match current colorMode(). The value is always returned as a float, so be careful not to assign it to an int value. The green() function is easy to use and understand, but it is slower than a technique called bit shifting. When working in colorMode(RGB, 255), you can acheive the same results as green() but with greater speed by using the right shift operator (>>) with a bit mask. For example, the following two lines of code are equivalent means of getting the green value of the color value c: r1 = green(c) # Simpler, but slower to calculate r2 = c >> 8 & 0xFF # Very fast to calculate |
