touchgfx::AbstractPainterRGB565::mixColors() method

@fn FORCE_INLINE_FUNCTION uint16_t AbstractPainterRGB565::mixColors(uint16_t newpix, uint16_t bufpix, uint16_t alpha, uint16_t shift) Mix colors. Mix colors from a new pixel and a buffer pixel with the given alpha applied to the new pixel.

Syntax

FORCE_INLINE_FUNCTION uint16_t mixColors(uint16_t newpix,     uint16_t bufpix,     uint16_t alpha,     uint16_t shift);

Arguments

newpix

The newpix value.

bufpix

The bufpix value.

alpha

The alpha of the newpix.

shift

The shift, 8 if alpha is [0..255], 16 if alpha is [0..255*255].

Return value

The new color to write to the frame buffer.
