주의
Note: Transparency is copied only with imagecopymerge() and true color images, not with imagecopy() or pallete images.
Note: The transparent color is a property of the image, transparency is not a property of the color. Once you have set a color to be the transparent color, any regions of the image in that color that were drawn previously will be transparent.
