Description
bool
imageantialias ( resource im, bool on )
Activate the fast drawing antialiased methods for lines and wired polygons.
It does not support alpha components. It works using a direct blend
operation. It works only with truecolor images.
Thickness and styled are not supported.
Using antialiased primitives with transparent background color can end with
some unexpected results. The blend method uses the background color as any
other colors. The lack of alpha component support does not allow an alpha
based antialiasing method.
Замечание: Эта функция доступна только в том
случае, если PHP был скомпилирован со встроенной библиотекой GD.
