Static p5_sys::global::blendMode[−][src]

pub static blendMode: BlendModeInternalType
Expand description

Blends the pixels in the display window according to the defined mode. There is a choice of the following modes to blend the source pixels (A) with the ones of pixels already in the display window (B):

  • BLEND - linear interpolation of colours: C = A\*factor + B. This is the default blending mode.
  • ADD - sum of A and B
  • DARKEST - only the darkest colour succeeds: C = min(A\*factor, B).
  • LIGHTEST - only the lightest colour 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.
  • REMOVE - removes pixels from B with the alpha strength of A.
  • OVERLAY - mix of MULTIPLY and SCREEN . Multiplies dark values, and screens light values. (2D)
  • HARD_LIGHT - SCREEN when greater than 50% gray, MULTIPLY when lower. (2D)
  • SOFT_LIGHT - mix of DARKEST and LIGHTEST. Works like OVERLAY, but not as harsh. (2D)
  • DODGE - lightens light tones and increases contrast, ignores darks. (2D)
  • BURN - darker areas are applied, increasing contrast, ignores lights. (2D)
  • SUBTRACT - remainder of A and B (3D)

(2D) indicates that this blend mode only works in the 2D renderer.
(3D) indicates that this blend mode only works in the WEBGL renderer.
