Description
bool imagesettile (resource image, resource tile)imagesettile() sets the tile image to be
used by all region filling functions (such as imagefill()
and imagefilledpolygon()) when filling 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(), a tile allows certain parts
of the underlying area to shine through can be created.
Замечание:
You need not take special action when you are finished with a tile, but if you
destroy the tile image, you must not use the IMG_COLOR_TILED
color until you have set a new tile image!
