This does the same thing as WindowBlendImage, except it operates on a single pixel (that is, a single RGB colour for the blend colour, and a single RGB colour for the base colour). This does the same thing, to a single pixel, as WindowBlendImage (with the same codes). This is intended for situations where you need to work on individual colours - either in a miniwindow image, or generally, to do things like merge them together in various ways.

Blend - the RGB code of the pixel to be blended

Base - the RGB code of the base pixel

Mode - the blending method.

Opacity - the amount of opacity, between 0 and 1 (floating-point number). An opacity of 0 means the result will be the base pixel. An opacity of 1 means the blend is fully applied. An opacity of 0.5 means the blended pixel is merged 50% with the original pixel.

Note: Available in version 4.36 onwards.

Lua example
BlendPixel (0x123456, 0x445566, 1, 0.5) -- mode 1 (normal) at 50% opacity (gives 0x2b445e)
Returns -1: The blend mode was not in the above list.

-2: Opacity less than zero or greater than 1.

Otherwise, the RGB code resulting from the blend operation.
Introduced in version 4.36
