Blends the pixels in the Py5Graphics drawing surface according to a defined mode.
Blends the pixels in the Py5Graphics drawing surface according to a defined mode. There is a choice of the following modes to blend the source pixels (A) with the ones of pixels already in the Py5Graphics drawing surface (B). Each pixel’s final color is the result of applying one of the blend modes with each channel of (A) and (B) independently. The red channel is compared with red, green with green, and blue with blue.
BLEND: linear interpolation of colors:
C = A*factor + B. This is the default.
ADD: additive blending with white clip:
C = min(A*factor + B, 255)
SUBTRACT: subtractive blending with black clip:
C = max(B - A*factor, 0)
DARKEST: only the darkest color succeeds:
C = min(A*factor, B)
LIGHTEST: only the lightest color succeeds:
C = max(A*factor, B)
DIFFERENCE: subtract colors from underlying image.
EXCLUSION: similar to DIFFERENCE, but less extreme.
MULTIPLY: multiply the colors, result will always be darker.
SCREEN: opposite multiply, uses inverse values of the colors.
REPLACE: the pixels entirely replace the others and don’t utilize alpha (transparency) values
We recommend using
blend_mode() and not the previous Py5Graphics.blend() function. However, unlike Py5Graphics.blend(), the
blend_mode() function does not support the following:
BURN. On older hardware, the
DIFFERENCE modes might not be available as well.
Underlying Processing method: PGraphics.blendMode
blend_mode( mode: int, # the blending mode to use /, ) -> None
