CLASS="function"

    modes of drawing on truecolor images. In blending mode, the
    alpha channel component of the color supplied to all drawing function,
    such as <A
HREF="function.imagesetpixel.html"
><B
CLASS="function"
>imagesetpixel()</B
></A
> determines how much of the
    underlying color should be allowed to shine through.  As a result, gd
    automatically blends the existing color at that point with the drawing color,
    and stores the result in the image.  The resulting pixel is opaque.  In
    non-blending mode, the drawing color is copied literally with its alpha channel
    information, replacing the destination pixel.  Blending mode is not available
    when drawing on palette images.
