SYNOPSIS

       bool imagesettile (resource  $image, resource  $tile)

DESCRIPTION

       imagesettile(3)	sets the tile image to be used by all region filling functions (such as imagefill(3) and imagefilledpolygon(3)) when fill-
       ing with the special color IMG_COLOR_TILED.

	A tile is an image used to fill an area with a repeated pattern.  Any GD image can be used as a tile, and by setting the transparent color
       index of the tile image with imagecolortransparent(3), a tile allows certain parts of the underlying area to shine through can be created.
