Py5Graphics.red()

Py5Graphics.red()¶
Extracts the red value from a color, scaled to match current Py5Graphics.color_mode().
Description¶
Extracts the red value from a color, scaled to match current Py5Graphics.color_mode().
The red()
function is easy to use and understand, but it is slower than a technique called bit shifting. When working in color_mode(RGB, 255)
, you can achieve the same results as red()
but with greater speed by using the right shift operator (>>
) with a bit mask. For example, red(c)
and c >> 16 & 0xFF
both extract the red value from a color variable c
but the later is faster.
This method is the same as red() but linked to a Py5Graphics
object. To see example code for how it can be used, see red().
Underlying Processing method: PGraphics.red
Syntax¶
red(rgb: int, /) -> float
