imagecolorresolve — Determines the closest color
int imagecolorresolve(image, red,
int image: Image
int red: Red component
int green: Green
int blue: Blue
Returns a color the same as - or as close as possible to
- the specified color. Unlike imagecolorexact() , but
similar to imagecolorclosest() , this
function always returns a color, even if the color
returned is not at all similar to the RGB values
specified. The function will move through the color
palette of the image until it finds a close match, which
may not be close at all.
